	+ PerParticleRandom still had some randomness in it
	+ UserColorCurve has a user color curve defined in 3 different components referencing the same system
	+ BasicSkinnedEmitter has 4 skinning sub-tests, attached as a subcomponent, referencing a world skeletal mesh, using a material filter, and using a bone filter

	+ added a skinning module that spawns based off exec index and a data interface that queries the number of triangles on a skeletal mesh.

	#tests auto tests pass

Change 3864729 by Frank.Fella

	Sequencer - Fixed a few places which were modifying sequencer data, but not calling the NotifySequencerDataChanged.

Change 3864737 by Frank.Fella

	Niagara - Fix the timeline in the niagara editor plus other fixes.
	+ Turned on looping in the timeline by default.
	+ Added simulation options to control playback in the editor, including turning off auto-play, disabling reset on change, and disabling resimulation when changing while paused.
	+ Added a buttons to the timeline for each renderer an emitter has which shows a renderer specific icon and will allow navigation directly to the renderer with future stack changes.
	+ Fixed issues in the emitter life cycle and spawn rate modules which were preventing delay and looping from working consistently. (includes auto-test)
	+ Added top level metadata for modules.
	+ Added the ability to add metadata to a module and it's inputs to allow it to be edited directly using timed sections in the timeline.  Currently configured for the emitter life cycle module.
	+ Changed the way the "MaxSimTime" on niagara component works so that it now represents the maximum frame time which should be used when seeking the component to the desired age.  This previously was the maximum amount of simulation time to run which would prevent simple effects from simulating quickly, and would also allow more complicated effects to hang the UI while seeking.
	+ Changed the behavior of niagara component when seeking to desired age so that it always uses the exact specified seek delta instead of trying to seek to the exact desired age.
	+ Fixed the component so that systems which are seeking to the desired age in the editor no longer draw in fast forward mode.
	+ Changed the default playback range for effects in the timeline from 1000 seconds to 10 seconds, and fixed the timeline so that the playback range is serialized into the asset which will persist the setting across loads.
	+ Fixed scrubbing in the timeline so that it doesn't immediately reset when scrubbing backwards.
	+ Added a button to the timeline track for enabling and disabling isolation mode for emitters.
	+ Added a checkbox to the timeline to enabled and disable emitters from the timeline.
	+ Fixed PinToNiagaraVariable so that it asserts if bNeedsValue is specified and it can't actually provide a value.
	+ Create a class called FNiagaraStackFunctionInputBinder which allows binding to an input of a function on a stack so that you can easily set and get the value of the input without having to worry about modifying the graph or rapid iteration parameter sets directly.

	#tests Existing auto-tests and 1 new test for life cycle changes.

Change 3867179 by Frank.Fella

	Niagara - Turn off GPU simulation for test assets for Shaun.

Change 3869201 by Simon.Tovey

	Bypassing JonLs issue

	#tests no longer crashes.

Change 3869897 by Frank.Fella

	Niagara - Fix crashes when using the skeletal mesh data interface.  NOTE: The change to the actual skeletal mesh data interface code doesn't seem needed, but without it, it crashes with the stomp allocator on.  We'll have to investigate further.

Change 3870487 by Frank.Fella

	Niagara - Always generate cached skin data immediately, and make sure we're not indexing triangles that don't exist.  This is a temporary fix to avoid a crash when changing the skeletal mesh source on an effect in the level from the details panel.

Change 3877378 by Frank.Fella

	Niagara - Update the burst and lifecycle modules with new metadata for incoming timeline changes.

Change 3877564 by Frank.Fella

	Sequencer - Fix a few more places which were modifying sequencer data without calling NotifyMovieSceneDataChanged.

Change 3877565 by Frank.Fella

	Niagara - Remove old unused burst code from some runtime classes.

Change 3877567 by Frank.Fella

	Niagara - Add support for keying bursts on the timeline which is configured using script metadata.

Change 3877699 by Frank.Fella

	Niagara - Fix a crash in the new timeline code for when you have bursts, but you have inputs on the emitter lifecycle bound, also set lower bound of view range of the timeline to be -.1 so that you can more easily interact with keys at 0.

Change 3877715 by Frank.Fella

	Sequencer - Update the change type when pasting keys from the clipboard from Unknown to TrackValueChanged to avoid unnecessary work.  From code review on last change.

Change 3879285 by Simon.Tovey

	A couple of fixes for using struct constants

	#tests Jon's case now compiles and works correctly.

Change 3879378 by Frank.Fella

	Niagara - Fix a few spots where recursive graph traversal was visiting nodes multiple times because of diamonds in the pin connections.  This reduces a terrible hang in UNiagaraScriptSource::InitializeNewRapidIterationParameters from 5 minutes to 5 seconds but there are futher issues to investigate becasue even 5 seconds it too long.

Change 3879858 by Shaun.Kime

	Moved the VM script compilation to the DDC in order to facilitate better team compilation behavior. Significant changes to the translator and overall compile workflow to make the data behave better for a future multi-threaded compilation path.
	In order to know when to compile, a key is generated that uses the compile id's of the graphs that influence the compilation of our node. In this way, if an end user goes and edits a function or module and checks in, the overall compile id will not match b/c that function is in the dependency list of a system downstream. The system will then know to recompile. However, everyone else on the team will generate the same key because the asset in question was checked in with its local compile id already changed.

	Additionally, we now employ change tracking on traversals from a node graph. These traversals walk through all the nodes leading to a given output node and see if they've been altered. If they have, a new compile id is generated. If not, the old compile id is used. This also means that if you edit a particle update section in the stack, the emitter section won't force the system to recompile.

	GPU scripts now have their own script slot rather than riding alongside particle spawn scripts. This allows us to address them independently in the translator and put them in the DDC as well. Once the text is generated, we then go back out to the DDC to generate the shader associated.

	Known issues:
	+ Emitters are sometimes marked dirty on open
	+ Nodes connected to event writes aren't part of the hashing
	+ DataInterface signature changes don't dirty the compiles
	+ Struct changes don't dirty the compiles
	+ On system loading, we go out to the DDC instead of using existing scripts, which is slower..

	#tests all auto-tests pass, additional tests run to validate proper behavior

Change 3879859 by Shaun.Kime

	Content update post DDC change

Change 3879862 by Shaun.Kime

	Niagara plugin content to ddc

Change 3879958 by Frank.Fella

	Niagara - Actually fix the bad recursion in this function by using the existing traversal method.

Change 3881727 by Damien.Pernuit

	Niagara - Houdini - Created a separate plug-in for the Houdini CSV Data Interface.

Change 3881877 by Simon.Tovey

	Fix for mac compile issue

Change 3882773 by Simon.Tovey

	Actual fix for Mike

Change 3882822 by Shaun.Kime

	Rather than throw a check, I instead emit an error when we can't match up a data interface and instantiate a CDO version. Not perfect, but this will let you recompile.

	#tests allows me to open jonathan's file

Change 3883538 by Shaun.Kime

	Moving particle-level scripts to compile with the emitter named Emitter in their internal scripts. This simplifies the dependencies quite a bit, but causes some complexity on the wiring side (most of which we were already doing anyway).
	Getting rid of some allocations in translation (still more to go).
	Fixed some of the logic for emitters that had modules of the same name to now properly concatenate.

	Compile version bumped, so all scripts will be forced to recompile. Not saving this into the test files for now, as I expect this to happen a bit for the near term.

	#tests all auto-tests pass, creating a new emitter and system on PC works

Change 3883552 by Shaun.Kime

	Fixing renaming to work properly now. It just invalidates the system script compile id's, forcing it to auto-compile.

	#tests auto-tests pass

Change 3884722 by Bradut.Palas

	Added searchbar with basic name search for Niagara stack

	#tests none
	#jira UE-53469

Change 3884793 by Shaun.Kime

	#tests created in editor, saw default was correct, carried through to VM runtime through attribute viewer

Change 3890849 by Shaun.Kime

	Porting over 4.19 fix to Dev-Niagara

	#tests allows creation of valid scripts even when ini is cleared.

Change 3891088 by Frank.Fella

	Sequencer - When getting selected tracks for the external selection api, include tracks if any of their child nodes are selected.  This matches the behavior object guid external selection.

Change 3891114 by Bradut.Palas

	Fixing crash that sometimes happens if a stack tree changes while a stack search is active

	#tests none

Change 3891131 by Frank.Fella

	Sequencer - Move section headers for bool, int, vector, and color to the public directory so they can be used by the niagara level sequence integration.

Change 3891165 by Wyeth.Johnson

	error for shaun

Change 3891354 by Shaun.Kime

	Adding Quat struct to more locations. Now treated like hlsl float4.

	#tests EulerToQuaternion now compiles

Change 3891463 by Bradut.Palas

	Fix crash that sometimes happens when deleting module and hitting Ctrl-Z to undo (the condition for removing the listeners from the rootentry should not be tied to the validity of weak pointers for system and emitter, because sometimes they are out of sync when changing the graph)

	#tests none

Change 3891641 by Wyeth.Johnson

	resave node

Change 3893143 by Shaun.Kime

	Fixing issue where you try to bind a vertex color sampler to a mesh without it. We failthe binding rather than crash due to a check later. Also fixed up error logging to only mention the one that failed.

	#tests can open NiagaraSystem'/Game/FX/SkeletalMeshDissolve/EmittersAndSystems/FightSceneDissolve.FightSceneDissolve' with an error..

Change 3893528 by Bradut.Palas

	fix another crash when search results are invalidated during search

	#tests can now copy and paste comment boxes

Change 3894012 by Bradut.Palas

	no longer executing search tick if the rootentry is null

	#tests none

Change 3894828 by Frank.Fella

	Niagara - Runtime changes to support sequencer animation
	+ Reset the simulation when force solo is changed on the component.
	+ Invalidate the render data and clear the buffers when resetting to avoid previously rendered particles from drawing.
	+ Automatically sync the override parameters in the component when the source assets exposed parameters change and removed forced syncing from various places.
	+ Remove lots of refresh code from the niagara component details which should not be neccessary anymore.

	#TESTS Ran autotests, tested through the UI while building the sequencer tests asests.

Change 3894832 by Frank.Fella

	Niagara - Level sequence support for spawning and animating system life cycle and select user parameter types.

	#Tests Ran existing tests and added a new test to verify added functionality.

Change 3896944 by Bradut.Palas

	safeguard entries with no search items (it actually can be null)

	#tests none

Change 3896948 by Bradut.Palas

	Fix assert when dereferencing source array (no need for a raw pointer to the array since it's initialized with the content anyway)

	#tests none

Change 3896950 by Bradut.Palas

	fix compile error with previous commit

	#tests none

Change 3897698 by Frank.Fella

	Niagara - Fix some safety issues with parameter initialization on the niagara component.
	+ Kill the current system if we synchronize parameters to avoid issues with data interface lifetime.
	+ Always sync parameters when the asset is set to prevent missing data interfaces in the override list.
	+ Add an enum to control how data interface parameters are handled when calling CopyParametersTo.
	+ When the system instance is copying the asset parameters, have it copy data interfaces by reference so that it's not creating data interfaces copies which will be deleted at the next garbage collection.

	#Tests Auto-tests, also doesn't crash anymore when opeining Jonathan's disolve effect and then opening a level.

Change 3897953 by Frank.Fella

	Niagara - Remove some namespace restrictions from the code that generates the available parameters to read from in the stack UI since it was preventing the use of custom namespaces in modules and it was not clear what issue it was solving since we already prevent scripts from addressing parameters from lower level scripts.  Also move user parameters to their own menu section.

	#Tests Custom namespaces are usable again in the stack.

Change 3898926 by Bradut.Palas

	Fix for crash caused by garbage collection and async search
	#jira UE-55284 (Stack search doesn't work on collapsed entries) now searching through unfiltered children, will need extra fixes on the stack to eliminate "ghost" results"
	Both are still under code review, submitting because they are simple to rollback and harmless to other features.

	#tests none

Change 3899069 by Shaun.Kime

	Parallel compilation

	Major changes:
	Rather than a custom streaming version that we know influences a rebuild, I'm moving away to a guid that you need to regenerate if you change the compiler in any meaningful way
	needed for multiple reasons,
	1) if two people are making changes to the compiler, having something other than a guid as the value makes the content of the ddc ambiguous
	2) when iterating I often need to make multiple changes to get to a working final result, bumping the version number each time that happens gets old fast

	We fully clone the input graph to do the compile in the background. While the translation step is not a huge amount of time, it keeps the main thread responsive.

	We currently have a big critsec around the crosscompiler to bytecode as it isn't threadsafe. Future changes will push this to the ShaderCompilerWorker.

	#tests all tests pass as well as stress tests around saving while compilng, long compile times, etc.

Change 3899071 by Shaun.Kime

	Fixing the availability flags for system and emitter scripts.

	#tests all auto tests pass

Change 3899077 by Shaun.Kime

	Fixing assets to have their wait on compile finished checkbox checked in the editor for testing

Change 3899184 by Bradut.Palas

	implemented categories for module inputs (now inputs can be assigned a category in the module editor and they will be grouped by those categories in the Niagara stack)

	#tests none

Change 3899329 by Bradut.Palas

	fix broken commit by adding missing new files NiagaraStackInputCategory.cpp and .h

	#tests none

	Niagara - Add WITH_EDITORONLY_DATA to prevent non-editor compile failures.

Change 3902477 by Frank.Fella

	Niagara - Fix FNiagaraEditorTypeUtilities to be a thread safe TSharedFromThis since it's always created with a thread safe shared pointer, also fix up issues related to this change.  Fixes a crash which occurrs when it's the target object of a delegate binding.

	#Tests adding a curve data interface to a parameter collection no longer crashes.

	PropertyEditor - PropertyRowGenerator - Added features and fixes to support integration into niagara's stack view.
	+ Added a method to get filter/search strings for an IDetailTreeNode to support external searching and filtering.
	+ Added a delegate to the layout builder for when one of it's owned nodes has it's visibility forcibly changed by a customization.
	+ Changed the filtering so nodes are generated for properties marked as advanced.
	+ Pass the notify hook down to the detail utilities so that change notifications work as expected.
	+ Add layout data for the widgets returned from the IDetailTreeNode to prevent alignment and sizing issues in custom implementations.

	- Shader now uses the DI default object to create the correct parameters struct.
	All parameter and buffer management now being handled inside this parameter struct.
	This allows far more encapsulated code for each DI.
	Allows us to reamove the GPU buffers from and the Scene texture refs that were in the base DataInterface class.
	Simplifies the API and process of implementing DI's on the GPU considerably.

	- Removed all existing GPU buffer support code and usage. All DIs now use a parameters struct.

	- Have moved tons of curve code into the base class, simplifying the child implementation classes.

	- Implemented GPU curve interpolation.

	- Removed bAllowUnnormalizedLUT. Confusing and now unnessessary. All curves do this by default.

	- Modified FNiagaraShaderMapId to use the latest FNiagaraCustomVersion::LatestScriptCompileVersion and bumped it.

	- Created NiagaraCore module and moved a few classes into it. Anything needed by both the shaders and runtime should be here.
	- Refactored DI hierarchy to base from a new UNiagaraDataInterfaceBase which is inside NiagaraCore.

	- Removed constness from many UStruct/UEnum/UClass pointers. Technically we don't ever need these to be non const so initialy coded as const. Some existing engine code however requires these be non const so had to propagate that back through our code.

	Making it possible to see the debug output if the console variables are set for shaders.

	#tests auto-tests pass

Change 4069628 by Shaun.Kime

	OpenGL is very picky about shutting down its texture buffers. We were improperly holding onto static resources and leaking OpenGLShaderResourceViews until module shutdown. Unfortunately, this is *after* the renderer has been shut down and the corresponding OpenGL managers have been deleted, causing us to call into deleted memory. By making several classes FRendererResources, we now register at the appropriate times. In several cases, since the buffers are special purpose fallbacks I moved them into helper locations that are build on demand.

	Removed FNiagaraVertexFactoryBase::DummyBuffer
	Created FNiagaraDummyRWBufferInt and FNiagaraDummyRWBufferFloat so that I could wrap several dummy RW buffers in RendererResources and TGlobalResource.
	Removed NiagaraEmitterInstanceBatcher::DummyWriteIndexBuffer

	#tests all auto-tests pass on PC and OpenGL and we can open and close OpenGL after using Niagara assets

	#jira UE-59000

Change 4069646 by Shaun.Kime

  MAJOR FEATURES & CHANGES
============================

Change 3870267 by Arne.Schober

	DR - SafeRelease SRVs that might be hold by the Vertexfactories (maybe due to indirect use in GlobalResources)
	Note that the VFs are not owners of the data, e.g the underlying Buffers might be released before this and this reference counting should be uneccessary

Change 3872507 by Arne.Schober

	Back out changelist 3870267

Change 3988916 by Marcin.Undak

	Quail/Linux compilation fix #rb none #codereview arciel.rekman

Change 4042277 by Rolando.Caloca

	DR - Clear UBs between PSOs on D3D to help track down not setting resources

Change 4042297 by Arne.Schober

	DR - Fix case where LPV requires SSAO to run but no GBuffer is available in formward mode. In this case we force the behaviour to use the simple AO (as ASyncAO pass)
	#jira UE-42135

Change 4042404 by Jian.Ru

	Fix a race condition when RT is disabled and then re-enabled
	#jira

Change 4042437 by Richard.Wallis

	Mac Localization - Mac now uses FUICommand and NSLOCTEXT to build main menu items.  Don't fetch menu items using name since that could change.  Lookup using ID's.

	Note:
	New CB function binding system in *FStartupApplicationToMacMenuBinder*.  Added to simplify the existing and new CB function binding.

	Update:
	Application menu now also gets an update on runtime langauge changed event.  Other menu's get updated anyway as per runloop updates.

	#jira UE-49526

Change 4042602 by Guillaume.Abadie

	Adds support for alpha channel in DOF.

Change 4042603 by Guillaume.Abadie

Change 4042671 by Guillaume.Abadie

	Massages DOF's shader code for HLSLCC.

Change 4042772 by Mark.Satterthwaite

	Expose the MTLComputePipelineState's label string.

Change 4043013 by Juan.Canada

	Fixed bounds of skeletal meshes could be inverted (min > max) with negative scaling. That was breaking occlusion tests in some scenes, creating flicking issues.
	#jira UE-49290

Change 4043171 by Rolando.Caloca

	DR - Workaround crash on hlslcc

Change 4043182 by Uriel.Doyon

	Fixed skylight issues when using pre-exposure.
	Improved IndirectIrradiance gbuffer encoding when using pre-exposure.

Change 4043452 by Mark.Satterthwaite

	Extensively refactor the MetalRHI GPU profiling code. There is now a "MetalProfiler Start/Stop/Frames=X" in-game command that will spit out JSON files similar to the platform-agnostic TracingProfiler, but this displays the command-buffer encoding and execution which actually makes sense with Metal where we can't arbitrarily insert requests for time-stamps and breaking command-buffers/encoders is expensive.

Change 4044732 by Richard.Wallis

	Fix for macOs restoring to fullscreen results in render with large black border.  Also tested that is fix doesn't seem to re-introduce UE-51270 (CL 3696161).  There appears to be an edge case that can cause the toogleFullScreen: method to not correctly expand window frame to the full screen size - we end up with a frame size of the previous setting.  Forcing the correct values doesn't fix the issue - the only consistant fix seems to be to re-introduce the - (NSSize)window:(NSWindow *)window willUseFullScreenContentSize:(NSSize)proposedSize delegate method.

	#jira UE-57549

Change 4044741 by Guillaume.Abadie

	Further insulate private plugin usage within MetalRHI.

Change 4046006 by Mark.Satterthwaite

	Simplify dependency on the private module and hope it now builds properly.

Change 4046612 by Mark.Satterthwaite

	Apple A9 introduced support for baseVertex & baseInstance, earlier GPUs don't support it at all. The code was incorrectly compiling shaders assuming they did at given Metal shader standard versions. Instead we always compile mobile shaders assuming they don't support base index & vertex and for dektop shaders we now need an A9 or better GPU for it to work.

	#jira UE-55234

	Supress warnings about the missing module when not available or enabled. Also make it work on all Metal platforms.

Change 4050290 by Mark.Satterthwaite

	Sort out the timebase for all the different Metal clocks when profiling - everything is now in microseconds and seems to line up! Need to rework all the other timing code similarly - but not in this commit.

	Extend the Mac & iOS Frame-Pacer API to proivde the target output time and the intended duration so that the MetalProfiler can record the display V-Blank window.

Change 4053111 by Rolando.Caloca

	DR - hlslcc - RequiresNegateDDY()

Change 4053402 by Mark.Satterthwaite

	Add instrumentation for buffer & texture allocation and shader & pipeline compilation to MetalProfiler. Everything that I personally care to track should now be in place but the implementation details are grim so there's still plenty of room for improvement.

Change 4053454 by Mark.Satterthwaite

	More attempts to allow the builders to compile for Mac in such a fashion that the private module's perfectly innocuous headers don't cause an error.

Change 4053765 by Guillaume.Abadie

	Fixes a failure in DOFGather's ShouldCompilePermutation() caused by R11G11B10 change.

Change 4057220 by Guillaume.Abadie

	Cherry-picks and reworks experimental AO decal from GDC 2017's The Human Race demo.

	AO decal are on purpose not supported with ASync AO, because the proper way location to do that would be right before whenever a pass use it, but is currently challenging to track down considering the screen space AO buffer is used a by a lot of different passes through the scene texture uniform buffer.

	- Fixed d3derror when resizing the window in multi-gpu.
	- Fixed d3d12 checks when exiting in multi-gpu.
	- Command context containter can now only be used with a single gpu mask. This cleans up passing the mask everywhere.
	- RenderPass now reuse the current GPUMask instead of assuming the view mask. Decoupling furter more the binding.
	- Removed of IRHIComputeContext::GetContextForGPUMask().
	- Removed GPUMask from QueueRenderThreadCommandListSubmit and QueueCommandListSubmit since it is now a member of FRHICommandListBase.

	- Command lists now have a GPU mask set at creation time.
	- Support for immediate command list GPU mask.
	- Using the new SCOPED_GPU_MASK where we previously used a new command list on the stack.
	- Refactored most NodeMask naming to GPUMask, and also "const FRHIGPUMask&" to "FRHIGPUMask".
	- Commandline option "-mgpu" is now replaced by "-MaxGPUCount=" and "-PresentGPU="
	- Multi-gpu modes are now controlled through  -mgpumode={ gpu0, gpu1, broadcast, avr, afr }
	- Defines WITH_SLI and WITH_MGPU now control the path to multi-gpu support in the engine.
	- Variable GNumActiveGPUsForRendering is now split in  GNumAlternateFrameRenderingGroups and GNumExplicitGPUsForRendering.

Change 3774677 by Arne.Schober

	DR - Deprecated SetLocal from the RHICmdlist

Change 3809579 by Chris.Bunner

	Back out changelist 3774677.

	#jira UE-53483

Change 3810363 by Mark.Satterthwaite

	More random fixes to mtlpp: most important is the extension to Buffer that allows creation of sub-buffers that are merely views onto a sub-range of the parent. These sub-buffers are valid to use throughout the mtlpp API with two exceptions: they may not be used for visibilityResultsBuffers and Set*BufferOffset functions cannot take this offset into account (as the encoder does not hold onto the buffers and I don't want it to). In the case of Set*BufferOffset the caller has to know what is going on and in the case of visibilityResultsBuffers it'll just assert as it isn't sensible.

	This makes it *much* easier to do things like sub-buffer allocation, though the caller must be aware of the alignment restrictions of their intended usage as they are not possible to enforce. For example, a call to SetVertexBuffer requires an offset alignment must match the alignment of the data-type in the shader for "device" resources, or for "constant" data it must be max(4, sizeof(datatype)) on iOS and 256 on macOS. This should allow for much more tightly packed sub-allocations than earlier approaches, though older drivers (e.g. Mac OS X 10.11) enforce only the coarser "constant" data restriction everywhere.

	rd_route v1.1.1 with attached TPS approval.

	For macOS function interposition which is useful for debugging and the occasional workaround.

Change 3845164 by Mark.Satterthwaite

	Add LLM support for macOS, including tracking of memory allocated in Objective-C. This makes use of runtime method swizzling in the Objective-C runtime and the rd_route library I added for Richard Wallis, which allows for arbitrary runtime function interposition and allows me to hook the custom allocators used in Apple's many Objective-C frameworks on which the whole macOS edifice is built. Objective-C objects are charged to the calling scope as they are too common to impose their own without murdering frame rate.

	We would need a TPS approval for an iOS function interposition library for this to work fully on iOS, if desired in the short term discarding LowLevelFree events that aren't in the map rather than asserting will workaround the problem.

	Fix the black ground scattering on Metal - we've had issues with the atmospheric fog calculations for a long time - one or more intermediate operations generates different precision on Metal so we end up passing -ve values into sqrt which then generates NaN/INF. For Metal when compiling this file and this file only #define sqrt() to sqrt(abs()) so that we don't see anymore unexpected black in atmospheric rendering. This is far from ideal but I don't want to make abs all inputs into every sqrt because AFAIK this is the only case where we have an issue, and until we to investigate each intermediate calculation that isn't ridiculously, soul-crushingly tedious, it isn't practical to identify the source of the error.

Change 3877428 by Krzysztof.Narkowicz

	Merged with tiny tweaks Ansel photography plugin improvements from Adam Moss (GitHub pull request #4426):
	-The free-roaming photography camera has new constraints by default, i.e. it can't pass through walls
	-Photography session can be started and stopped programmatically, e.g. making it possible to bind photography to an alternative hotkey or button combo. This was an often-requested feature.
	-Tweakables and utilities are now exposed through a Blueprint Function Library (rather than direct manipulation of console variables)
	-The Ansel photography session UI now exposes some engine effect tweakables as sliders. For example, if the game is using depth-of-field then sliders are made available to allow the photographer to change the focal depth etc. The developer may suppress this behavior through the Blueprint Function Library.
	-Letterboxing is now removed during multi-part capture, d'oh.
	-Tiled shots are taken at full resolution even if ScreenPercentage < 100
	-SSR is enabled during super-resolution shots since Ansel is now better at hiding any ensuing artifacts
	-Postprocess settings are frozen at session start to avoid discontinuities during photography, i.e. wandering between postprocess volumes when the camera auto-moves for stereo and 360 shots.

Change 3891925 by Yuriy.ODonnell

	Fix/workaround for inconsistent preprocessor definitions for NVAftermath that result in FD3D11DynamicRHI class layout mismatch. NVAftermath support is now enabled by default for Win64.

	NVAftermath is declared as a private dependency in D3D11RHI. It does not automatically propagate to modules that explicitly include private RHI headers (OculusHMD, OSVR, OSVRInput). This results in NV_AFTERMATH being defined while compiling RHI module and not defined when compiling other modules, causing memory corruption at runtime.

	The long-term solution for this and similar issues requires some mechanism for adding transitive module dependencies, so that anyone that depends on D3D11RHI module would automatically also get the NVAftermath. Additionally, private headers should *never* be included directly by external modules.

	The short-term solution is to explicitly add NVAftermath dependency to OculusHMD, OSVR and OSVRInput.

	Additionally, NV_AFTERMATH is no longer forced by D3D11RHIPrivate.h when it's not defined. This allows catching this kind of mismatch in the future through a compiler warning (C4668).

Change 3932819 by Daniel.Wright

	[Integrate] Scene Textures uniform buffer
	* Base Pass Uniform Buffer now contains a Scene Textures uniform buffer.  Previously the translucent base pass had to check ~40 loose scene texture parameters every draw.
	* FMeshMaterialShader's must now bind PassUniformBuffer and supply a valid pass uniform buffer.  For most passes this is just FSceneTextureUniformParameters.
	* FRendererModule::DrawTileMesh can now cleanly set dummy scene texture resources, just by configuring how the pass uniform buffer is created.
	* Moved scene texture shader functions out of Common, into SceneTexturesCommon which must be manually included by shaders that want to use them
	* Separate Mobile Scene Textures uniform buffer to silo the platform complexities

	Moved DBuffer inputs out of FDeferredPixelShaderParameters and into FOpaqueBasePassUniformParameters

	Removed per-frame material uniform expressions.  GameTime material node with period is now implemented with an fmod in the shader, without the use of MaterialFloat, so that it will happen at full precision.
	* Per-frame expressions were used when the GameTime material node had a period, to do the fmod on the CPU where 32 bit precision is guaranteed, for mobile GPU's where pixel shader precision is sometimes less than 32fp.

	Moved forward shading data into the Base Pass Uniform Buffer
	Removed instanced stereo support for the light cull grid - will have to be reimplemented without changing SRV's per draw
	Base pass sets View Uniform Buffer from DrawRenderState instead of choosing which one to set per-draw

	Moved FSceneTextureUniformParameters out of the opaque base pass uniform buffer.
	* Base Pass shaders now enable SCENE_TEXTURES_DISABLED when compiling for a material of any domain other than MD_Surface.  These are used when rendering thumbnails of a material in a different domain, which could be opaque, but the opaque base pass drawing policy does not bind a scene textures uniform buffer, so the shader must not bind it.
	* Opaque materials can no longer use EyeAdaptation.

	Clone of CL 3974146 converted for mtlpp along with extra mtlpp usage suggestions by Mark Satt:

	Fix for black flickering on first paint with weighted material landscape on Mac.  When using AsyncCopyFromBufferToTexture in Metal we put the blit operation on the prologue encoder - however after a draw call using that resource the copy operation should happen after on the current encoder, this keeps the correct order of operations.

	Added Bool return from various Asnyc renderpass resource requests so caller can decide correct further action.  Updated to include the other async functions.

Change 3985087 by Mark.Satterthwaite

	Make sure that the particle scratch buffer is large enough to hold all the data for the curve texture we are rendering to, otherwise a full set of curves will start scribbling memory after 64Kb (the curve texture is 256Kb of data - 512x512x4 as sizeof(RGBAUInt8) == 4).

Change 3987039 by Yuriy.ODonnell

	Initial implementation of tracing profiler to show CPU and multiple GPUs on the same timeline. Currently only supported on DX12 platforms.

	Use `TracingProfiler frames=N` console command to trigger a capture of the next N frames. Trace is saved to disk as a JSON file into `Saved/Profiling/Traces` directory.
	Trace file uses Google Tracing format and can be visualized in Chrome built-in profiler (chrome://tracing).

	`r.GPUStatsChildTimesIncluded=1` CVar makes timing scopes hierarchical.
	`TracingProfiler.BufferSize=N` CVar controls the size of the tracing buffer, which may need to be increased for long traces (default is 65k events). Only can be set at startup.

Change 3990064 by Mark.Satterthwaite

	Ensure that packed globals are reuploaded when the command-encoder is restarted - don't simply invalidate the existing parameters. This properly handles cases where a single logical render-pass is broken into multiple command-encoders and/or command-buffers - otherwise all shaders must reset all parameters each time. When we move between frames we *do* want to perform a full state reset though as previous frame globals are treated as invalid.

Change 3990080 by Mark.Satterthwaite

	Change the way we invalidate the visibility buffer between command-buffers and command-encoders so that on iOS you can reuse the same buffer within the same command-buffer, but not across more than one. The code provides an exception to this rule when running under the MetalRHI validation tools which can break each draw call into its own buffer.

Change 3993923 by Krzysztof.Narkowicz

	Fixed crashes inside RemoveSpeedTreeWind() and RemoveSpeedTreeWind_RenderThread().
	FStaticMeshComponentRecreateRenderStateContext didn't flush deferred render updates causing stale RenderData to be left:
	1. Thumbnail manager called SetStaticMesh(nullptr), which added StaticMeshComponent to deferred render updates.
	2. UStaticMesh::Build called FStaticMeshComponentRecreateRenderStateContext and destroyed DenderData, but didn't touch Thumbnail's manager StaticMeshComponent as it was nullptr.
	3. This resulted in a StaticMeshComponent with stale RenderData pointer.

	Texture Streaming Changes and Fixes:

	- Static components added after the level is registered in the streaming manager are now handled correctly (fixes the low quality on the chests)
	- Dynamic components do not need to register to the streaming manager anymore.
	- Optimized dynamic component management by removing duplicate entries in the update list.
	- Added a pregarbage collect pass to the dynamic component management to optimize GC handling.
	- Added a budget reset logic whenever the scene requirements change significantly.
	- PIE worlds now have correct visibility information.
	- Fixed possible invalid memory access when processing the streaming manager slave views.
	- Refactored the incremental level texture data build to prevent new components from being unhandled.
	- Removed StreamingManager callbacks for NotifyActorSpawned() and NotifyPrimitiveAttached()
	- Added a StreamingManager callback NotifyPrimitiveUpdated(), to be used whenever a primitive streaming state must be updated.

	No video when playing HLS streaming video on Mac.  2 Issues, FPS was zero making duration for video sample buffer nonsense and Video Track dimensions were going to zero on the AVAsset once fully initialized when playing HSL streams.  Now cache relevant details and handle zero frame rate.

	Notes:
	- Caching the frame rate is not as important as we could look it up each time and fix for zero - ignoring that at the moment.
	- Assume we DO NOT want the FrameSize to be the last fetched video frame size from the AvfMediaVideoSampler as I think that is the video quality for streaming video and not the media frame size.

Change 4018251 by Mark.Satterthwaite

	Fix broken rendering on Metal that tracked back to the innocuous looking changes in CL #4006495 (no blame attached - these changes are entirely reasonable) and cause various bugs in QAGame's TM-DistanceFields, ElementalDemo and probably more. Doesn't fix broken SpeedTree rendering :(.

	MetalRHI was allowing uniform buffers to blow away linear texture buffers when the constant buffer has been elided due to dead-code elimination. This problem can manifest without linear textures if the uniform buffer contains both constant data and a resource-table but the shader doesn't use any of the constant data. That's because Metal doesn't separate constant buffers from any other kind of buffer unlike D3D which separates all the slots out - and Metal doesn't provide enough buffers to emulate the D3D arrangement. So far this has only manifested in the MVF + Linear Texture case but a more robust solution will be necessary long term.

Change 4025337 by Yuriy.ODonnell

	Improved use-after-free detection mechanism and physical memory usage of MallocStomp on Windows.

	MallocStomp on Windows will now reserve virtual address space for every allocation and then commit physical pages only to the valid usable part.
	Physical pages will be unmapped on Free, but virtual address space will not be released and therefore will never be re-used.

	Virtual address space is allocated from the OS in blocks of 1GB and then linearly sub-allocated.
	This reduces VA space usage, as VirtualAlloc returns blocks on 64KB granularity even if we just need 4KB. As a small bonus, this also reduces number of syscalls per allocation.

	This dramatically increases accuracy of use-after-free detection, but consumes significant amount of memory for the OS page table.
	Virtual memory limit for a process on Win10 is 128 TB, which means we can afford to keep virtual memory reserved for a long time.
	Running Infiltrator demo consumes ~700MB of virtual address space per second.

	Additionally, committing physical pages only for the usable part of the entire virtual block reduces physical memory usage by ~30% compared to old behavior,
	which allocated and committed entire block of pages via BinnedAllocFromOS and then marks border page as non-accessible.

Change 4030225 by Yuriy.ODonnell

	Static analysis warning fix: make sure declaration of Sleep() is consistent between Windows headers and TBB

	The complexity with this particular case is that the warning is generated in synchapi.h, which is included by some Windows headers.
	If a module includes TBB and then Windows platform headers, static analyzer will report this warning.
	Suppressing it would require wrapping all instances of Windows header includes in third-party macros.

	Current pragmatic solution is to modify the Sleep() declaration in TBB header to be consistent with Windows and to report the issue to Intel for a permanent fix.

Change 3903799 by Daniel.Wright

	[Integrate] Pass Uniform Buffers
	* All pass-constant shader inputs should go into the appropriate pass uniform buffer, instead of being set per-draw
	* Moved many per-draw base pass parameters over to the Base Pass Uniform Buffer
	* Opaque and Translucent base pass shaders have different uniform buffers, which allows compile errors when accessing an invalid resource (eg GBuffer in Opaque), instead of silently falling back to GBlackTexture

	Uniform buffers can now contain nested structs with UNIFORM_MEMBER_STRUCT()
	* This allows composing a uniform buffer at a particular update frequency out of many features, with encapsulation of each feature's parameters in a struct.
	* Eg deferred fog uses FFogUniformParameters, but so does translucency in the base pass, where FFogUniformParameters is reused nested inside the base pass uniform buffer.
	* Resources can now be located anywhere in the uniform buffer.  Padding is inserted to the cbuffer representation to keep memory layouts matching.  In the future the cbuffer could be compacted.
	* RemoveUniformBuffersFromSource() which works around HLSLCC lack of struct initializers now handles nested structs

Change 3979171 by Mark.Satterthwaite

	Copying //Tasks/UE4/Dev-UERNDR-354-mtlpp to Dev-Rendering (//UE4/Dev-Rendering):

	Rewrites MetalRHI in terms of mtlpp, which is a C++ wrapper library built around Metal's Objective-C API that attempts to reduce overheads and eliminate resource lifetime errors.

	Regarding mtlpp:
	- The mtlpp library uses C++ constructor/destructor and smart-pointer style management of Objective-C retain/release calls to prevent over- and under-release problems.
	- To reduce Objective-C overheads the mtlpp library caches the internal C-function that implements the Objective-C selectors for the most commonly used Metal protocol types and calls the function directly - this avoids objc_msgSend which does this look-up dynamically and thus improves CPU performance slightly.
	- Another advantage is that mtlpp provides infrastructure to extend the Metal API slightly to help improve MetalRHI - the two important aspects are mtlpp::CommandBufferFence which provides a consistent CPU<->GPU synchronisation primitive and sub-buffer allocations from mtlpp::Buffer which allow for far superior memory management.
	- Validation functionality is also provided by mtlpp to detect CPU vs. GPU data races and resource lifetime validation - this is expensive and is thus optional and compiled out from Shipping binaries that should be used when performance is most critical. The validation only works between resource modification and *submitted* command-buffers - anything that is being actively encoded on the CPU is ignored and it remains the responsibility of the application to validate the order of operations when encoding.

	Apple Platform:
	- LLM support which tracks Objective-C objects is enabled only on macOS - we don't have the necessary libraries to intercept and override the internal system calls on iOS.

	MetalRHI:
	- All the types are switched over, (mostly) insuling the external API from the horror of Metal and Objective-C.
	- Buffers are now managed quite differently, small buffers are allocated from a magazine allocator that allocates in fixed blocks from a larger parent buffer, intermediate sized buffers are allocated from a simple heap allocator that wraps a larger buffer and anything of reasonable size (>2Mb) will use the pooled allocator. This *radically* reduces the number of buffer resources, by as much as a factor of 10, because they are now sub-allocated without the need to use MTLHeap or MTLFence so they are performance equivalent to the existing implementation on the GPU and much faster on the CPU. Total memory use is approximately the same.
	- Vertex & index buffer management has been updated to reflect changes in the management and to avoid reallocating buffers which provide a Linear Texture (for SRVs) unless strictly necessary. This ensures that even in cases where a dynamic buffer is updated multiple times in a frame it will still work acceptably well.
	- The Metal ring-buffer implementation is completely different again, this time it can use Managed memory on macOS which allows for much better performance on eGPUs which will be more and more important for Mac.
	- Everyone that needs to wait on a command-buffer fence (rather than a command-buffer itself) now use mtlpp::CommandBufferFence, which prevents race conditions between the different command-buffer handlers (which sometimes execute out of order).
	- LLM tracking should now report the same data as the MetalRHI stats group for buffer & texture allocations - there is no segmentation for Vertex/index/Structured/Uniform allocations in Metal so these numbers are going to be wrong and will need to be rethought.
	- What will be unseen are the number of small but important resource usage fixes that avoid stale resources from being bound to the device after the point at which they become invalid. This should eliminate a class of errors where the GPU uses a resource pointer that is modified by the CPU and was necessary to satisfy the new mtlpp validation code.

	Other:
	- Remove the Metal focused workarounds from the ClothBuffer resource binding and related vertex-buffer SRV - these were put in when MetalRHI/MetalShaderFormat couldn't handle float->uint conversions correctly and they should now.
	- Fix a validation error caused by trying to render a 0-sized scissor rect which is invalid in Metal and simply pointless elsewhere.
	- Consistency of disabling the Manual Vertex Fetch behaviour in shaders.

Change 3697488 by Richard.Wallis

	Fix for Mac editor session no longer accurately tracking Mouse location after moving between Desktops in Mission Control on 10.12.6.  Problem stems from the extra call to update the slate cached window position in mouse move while dragging, which is itself is a hack but apparently this is needed as we don't get window position updates on Mac while dragging (although I couldn't see any -ve side effects without it) then the OS (in 10.12.6) doesn't always push out a final window did move notificaiton when changing desktops which leaves the window according to slate incorrectly positoned to it's frame.

	Solution is to either remove the mouse-move-while-drag window position hack or add a final window position update to the mouse-up event while dragging - this change is the latter.

	#jira UE-37553

Change 3697501 by Richard.Wallis

	Move audio processing over to audio bus tap.  Currently on Mac Media audio playback uses OS media player mixer rather than Engine as existing implemtation, using AVAssetReader, now suffers from poor performance with new Media Framework.  This audio tap version replaces that asset reader implementation but also suffers from bad quality audio hence is still disabled at the top of AvfMediaTracks.cpp.

	Original Code Review Description:

	Convert Mac to Play audio through the engine MediaFramework API rather than using AVMediaPlayer.  This is the Mac implementation only - this should work ok on iOS but unable to test due to missing audio type implementation (throws error "Init Buffer on unsupported sound type name = Synth type = 5"), as such is only enabled for Mac.  There maybe some extra tweaks required for iOS on app backgrounding etc if this feature is enabled.

	- Stuttering Audio Performace issue investiagation:  Re-Tested this implementation against [now fixed] current Mac implementation which was working fine last year and that implementation now has the same audio output quality (performance) issues as this one.  Basic investigation seems to point to somewhere in the engine audio handing.  When poor audio is heard the FMediaAudioResampler::Generate() function is dequeing an IMediaAudioSample sample buffer and the audio sample queue usually has 50-100 of these IMediaAudioSample buffers waiting in the queue.  I think the AvfMedia playback system is providing the sample buffers in good time but they are not getting consumed "fast" enough.  This under consuming also occurs if I force the Core Audio - Audio Unit mixer to use 48000 samples/sec.

Change 3705000 by Chris.Bunner

	Skip compiling opacity and opacity mask inputs on opaque surface materials. Previously the code was always added to the shader, sometimes we force opaque materials down a masked path which then calls the dormant code unintentionally. A safer fix for UE-48254.
	Partially reverted previous fix in CL 3608303 which removed a material instance optimization caching the overridden base properties.

Change 3706650 by Gil.Gribb

	UE4 - UE4 - Changes from intel. Increase number of worker threads on Windows to if hyperthreads (hyperthreads √ 2) else cores √ 1 up to a max of 22 workers. Increase MAX_THREADS multiplier per bank from 22 to 26. Intel VTune ITT event annotations. Wrapped in same function as your existing CPU events and enabled with √vtune. Optimize NV cloth by consuming FVector instead of FVector4 out of the solver. Vertex buffers were using FVector all along. ~15% improvement. Optimize cloth copy to vertex buffer by adding prefetch (similar to how bones are already done). Move local to world cloth transform from CPU to GPU. When simulating lots of vertices game thread was becoming bottleneck doing matrix multiply. Add your TaskGraph task switch latency test code.

Change 3710454 by Mark.Satterthwaite

	Refactor the way we compile Buffer<> & RWBuffer<> types for Metal so that we can support the type-conversion semantics of HLSL/D3D.
	- Buffer<> types are converted to Linear Textures unless the internal type is 3-compnent or the STRONG_TYPE macro is added as a type-qualifier. Linear Textures require an MTLTexture "view" object be created around the MTLBuffer which is the backing-store and it is typically best if that buffer is marked as Private (GPU-only) memory, reading from this in the shader then uses the texture-fetch hardware to perform the format conversion on load.
	- RWBuffer<> & 3-compnent Buffer<> types are converted to use template functions to load/store - the implementation of which will read the format from the BufferSizes meta-table and determine which type-conversion to apply. Function-constants are used to specialise the shader where feasible to reduce branch costs (function-constants are a Metal feature that allow efficient runtime recompilation of bytecode shaders).
	- Buffer<> & RWBuffer<> types where the STRONG_TYPE macro is added as a type-qualifier (only does something on Metal, everywhere else it is #define'd away) are compiled as "raw" Metal buffers of the inner-type (e.g. float4 for Buffer<float4>) and the MetalRHI runtime will enforce that only SRVs/UAVs of the proper format are bound to it. This is necessary in a couple of cases (BoneMatrices, NumCulledLightsGrid, CulledLightDataGrid & ForwardLocalLightBuffer buffers) which are used in a larger number of shaders as Linear Textures have poorer performance than Buffer<>/RWBuffer<>.
	- Most of the complications to generating subtly different Metal code for different OS/device combinations have been factored out into ue4_stdlib.metal which acts as an extension to the Metal shader standard-library and helps simplify the MetalBackend code - particularly helpful for Buffer<>/RWBuffer<> but also texturecube_array and the SM6 wave-related intrinsics.
	- Reverted some of the awkward Metal-specific changes Richard.Wallis & Arne had to make to the high-level shaders as they aren't necessary anymore.
	- Made the existing Metal-specific changes to use uint32 for all light-grid injection buffers apply to all Metal platforms again (I had hoped that it would not be necessary anymore, but it is much faster this way).
	- STRONG_TYPE is actually hlslcc's "invariant" keyword applied as a type-qualifier to a Buffer<>/RWBuffer<> type - only valid when using Metal which exports this through ILanguageSpec and #define'd out for everyone else.
	- Old versions of iOS (anything earlier than iOS 10.3) won't be able to use this new code, so every buffer will be treated as "raw" and the MetalRHI will now properly report when something goes awry rather than it leading to mysterious rendering errors and crashes.

Change 3710456 by Mark.Satterthwaite

	Fix the Eddie workset project generator so that Enterprise projects don't get mixed in with regular projects at the top-level because of the way Eddie combines workset groups.

Change 3710580 by Mark.Satterthwaite

	Alright then - if I can't use the C++11 extended string semantics I'll have to use "xxd -i" to generate a hex-dump include header from ue4_stdlib.metal instead. This can only be updated from a machine with access to the POSIX xxd command (Mac & Linux, possibly the new Linux sub-system for Win10).

Change 3713406 by Mark.Satterthwaite

	Use GPU morph targets on Mac - the necessary buffer conversions will always be available there. For iOS it can only be supported if iOS 10 is the minimum OS & Metal standard so leave that on the CPU path for now.

Change 3713494 by Richard.Wallis

	Fix for hitch when PIE unloading sublevel.  PerformReachabilityAnalysisOnObjects is spawing multiple threads in Editor builds as there is an extra code path that results in Critical Section locking within a singleton type static object - this is a bottle neck for multiple threads.  However they all just need to read the data not change it.  Replaced FScopeLock with a Read/Write version allowing these threads to all take a read lock at the same time to reduce contention.

	Changed the FUObjectAnnotationDense implementation only - left the sparse implementation alone as its not currently affecting this - although we could proactivly change that too.

	Also tested again repro in linked bug UE-24711.

Change 3713623 by Mark.Satterthwaite

	Implement ByteAddressBuffer/RWByteAddressBuffer in hlslcc in a similar manner to StructuredBuffer/RWStructuredBuffer so that the backends don't need too much modification. Implement the necessary changes into MetalBackend to make this work for Metal.

	Load/Store{+2,3,4} & Atomics are supported. Counter operations are not supported and aren't likely to be.

Change 3713636 by Mark.Satterthwaite

	Enable LPVs for Mac Metal.
	- Rework some multi-dimensional arrays & array-index dependent HLSL code that hlslcc simply can't cope with, the mesa-glsl compiler core is only capable of dealing with 1 dimensional arrays and array-indexing can't itself be directly dependent on the result of an array-index operation.
	- MetalRHI needs to ignore any SetRenderTargets call that binds nothing at all as you must bind at least one target (UAV, RT, Depth/Stencil) for it to be able to do anything sensible.
	- Turn on LPVs for Metal as it works now.

Change 3716271 by Daniel.Wright

	Lightmass correctness fixes
	* After these changes, point, spot, directional and sky lights closely match reference renderer Mitsuba after light unit conversions
	* Photon density trimming intended for direct photons was affecting indirect photons as well.  This caused high noise for point / spot lights with a large attenuation radius.  Indirect photon density even for small lights is 5x with this change, which improves 2nd bounce quality.
	* Removed legacy fudge factor on point / spot light photon energy
	* Spotlights no longer emit based on indirect photon paths.  Fixes excessive photon energy from spot lights as they were emitting outside of the cone.
	* Fixed photons computing one more bounce than requested.
	* Added an option to use the Radiosity solver for all multibounce, replacing photons.  Useful as a reference but generally too much noise indoors.
	* Fixed visualization of photons without final gather

Change 3721232 by Mark.Satterthwaite

	No more Metal Shader Model 4 - instead we have to have a Metal Shader Model 5 w/o Tessellation as Nvidia's shader compiler is broken on all tessellation shaders in 10.13.0 and above. There is no guarantee that they will fix this prior to 10.14 and I can't afford to disable tessellation entirely as if I do that then the AMD & Intel compilers will also regress. As there is no Shader Model 4 platform on Mac anymore I've amended the LevelEditorActions to disable the preview modes when no appropriate shader platform is available.

Change 3722943 by Mark.Satterthwaite

	Disable the METAL_SM5_NOTESS shader platform again - I can workaround the Nvidia pipeline state compiler crash by changing the buffer address space from "constant" to "device" as we're managing to confuse the poor thing. This won't materially affect AMD or Intel as they don't care much about this, but to limit performance issues on Nvidia we only need to do this for Tessellation Compute shaders.

Change 3723100 by Mark.Satterthwaite

Change 3695086 by Guillaume.Abadie

	Render thread dynamic resolution & TAA upsample.

	Merging //Tasks/UE4/Dev-DynamicRes/...@3694528 to //UE4/Dev-Rendering/...

	New features breakdown:
	- TAA upsample compute shader that accepts screen percentage from 50% to 200%, with a faster shader permutation for consoles;
	- Material no longer have to deal with BufferUV, and post process material after TAA upsample can sample any scene buffer seamlessly;
	- Material texture per view mip bias to produce sharper images with TAA upsample;
	- Render thread dynamic resolution heuristic is fully plugable by game code (for VR plugin specific heuristics);
	- Dynamic resolution in PIE and game builds;
	- Busy time queries in the RHI to be implemented on the different platforms so that the dynamic resolution heuristic can  exactly associate GPU frame times with screen percentages in its history;
	- Game user settings to enable/disable dynamic resolution;
	- In editor viewport screen percentage config to previsualise and test content at different screen percentage.

	Fixes:
	- Various fixes for algorithms producing different outputs at different screen percentage.
	- Various fixes for algorithms sampling outside view rects.

	Refactors:
	- TAA shader
	- Moved some screen percentage specific members from FSceneView to FViewInfo for thread race bullet proofing.

	Aknowledgements:
	- VR plugins are broken
	- DFAO still have some artifacts

	Premiliminary review: Marcus.Wassmer
	Review for TAA refactor and TAA upsample shader: Brian.Karis
	Review for dynamic resolution: Brian.Karis

  MAJOR FEATURES & CHANGES
============================

Change 3441680 by Uriel.Doyon

	Added units to point light intensity, to allow the user to specify the value in candelas or lumens.

Change 3512288 by Rolando.Caloca

	DR - Fix issue when recycling image handles

Change 3512338 by Michael.Lentine

	Fix precision if user enters a multiple of 90 degree rotation for transforms.

	This will only work for exact values. Generally comparing float point numbers using == is unsafe but it should be ok in this case as they are exact values entered from the UI. We may want to later expand this to include thresholding using a value ~1e-7.

Change 3513112 by Richard.Wallis

	Crash when packaging for iOS with Shared Material Native Libraries and Share Material Shader Code from windows platform.  Offline shader compile for archiving not done - shader header has missing offline compile flag for native Metal library archiving.

	Fix includes:
	- Handle offline compile failure when not running on Mac and no remote is configured (or remote fails). (I think it's this point at which the crash in the bug report is at).
	- Make sure remote can build for native Metal libraries and archive correctly - this should now support Linux platforms or Mac to Mac (if enabled in MetalShaderCompiler.cpp) for testing if required.
	- Updated to include remote calling into the xcode 9 Metal pch fix already submitted by Mark Satt.

	#jira UE-45657

Change 3517039 by Yujiang.Wang

	GitHub #2655: Optimization for shadow map resolution selection for spot lights

	* Use the radius of the inscribed sphere at the cone end as the spot light's screen radius

	Note: slight drop of shadow quality of spot lights may occur when they are far away from the camera. This is intended, since before this optimization they tend to be always rendered with the maximum shadow map resolution (2048), which is very costly

	#jira UE-33982

Change 3517069 by Yujiang.Wang

	Fix for ScissorRect settings in d3d11 being lost under certain scenarios

	* Scissor rectangle is always enabled in the low-level d3d11 pipeline, and it is expected that at least one ScissorRect is present no matter whether RHISetScissorRect is called with bEnable=false (when it is false we just use a big rect to make it effectively disabled)
	* However FD3D11StateCacheBase::ClearState() clears all the states, which removes scissor rectangles and causes problems for certain routines (FScene::UpdateSkyCaptureContents)
	* Now SetScissorRectIfRequiredWhenSettingViewport will always set a effectively disabled ScissorRect on each FD3D11DynamicRHI::RHISetViewport call, just like d3d12 does

	DR - Fix linking issue

Change 3525459 by Daniel.Wright

	Volumetric Lightmaps - higher quality precomputed GI on dynamic objects and GI on Volumetric Fog
	* Enabled by default on all maps, effective after a lighting build.  This replaces the existing Precomputed Light Volume and Indirect Lighting Cache features.
	* New Lightmass World Settings: VolumeLightingMethod, VolumetricLightmapDetailCellSize and VolumetricLightmapMaximumBrickMemoryMb.
	* Lightmass computes lighting samples in an adaptive grid, with higher density around geometry inside the importance volume.  Positions outside the importance volume get lit with the border texels.
	* Improved Lightmass volume solver to use importance photons and full adaptive final gather, so volume samples have similar quality to 2d lightmaps.
	* A static indirection texture is built covering the importance volume and flattening the brick tree by storing the offset to the highest density brick at each indirection cell.
	* Seamless and efficient GPU interpolation across density levels is achieved by adding a single row of padding to bricks, copied from neighbors, and stitching up bricks with lower density neighbors
	* The Volumetric lightmap stores Irradiance as a 3 band SH, which is 27 floats, quantized into 28 bytes, 7 texture lookups.
	* A full screen barebones material using Volumetric Lightmaps costs .42ms on 970 GTX, while Indirect Lighting Cache Point costs .32ms
	* Sky bent normal is also stored for stationary skylights and Directional Light Shadowing for Single Sample Shadow receiving.
	* Volumetric fog, Movable components, unbuilt Static Components, SingleSampleShadow receiving and Capsule Shadows use Volumetric Lightmaps if available
	* New Visualization show flag for Volumetric Lightmap sample points
	* Level streaming of volume light data is not currently supported with this method

Change 3525461 by Daniel.Wright

	Lowered default r.Shadow.RadiusThreshold for Epic shadow settings as it was causing a lot of visible artifacts from small objects popping out.  This will increase shadowmap cost slightly (13.5ms RT -> 14.3ms RT in Fortnite on PS4, no measurable GPU difference).

Change 3590961 by Mark.Satterthwaite

	Submitted on Richard Wallis's behalf as he's on holiday:

	Mac fixes for Compute Skin Cache rendering issues (resulting in incorrect positions and tangents) and for recomputing tangents.  Problem sampling from buffers/textures as floats with packed data.  Some of the data appears as denorms so get flushed to zero then reinterpreted as uints via asuint or in Metal as_type<uint>().  Fix here for Metal seems to be to use uint types for the skin cache SRV's and as_type<> to floats instead.

	There could be some other areas where we're unpacking via floats that could affect Metal and I'm not sure how this will impact on other platforms.

	Correctly implement ClipDistance for Metal as an array of floats as required by the spec. and fix a few irritating issues from the merge that should not have.
	- When compiling a tessellation vertex shader in the SCW direct mode we can't evaluate non-existant defines and we don't actually need to.
	- The define names, values & shader file name are irrelevant to the Metal output key, but the shader format name & Metal standard really do matter - should speed up Metal shader compilation a bit.
	- Move the shader vertex layer clip-distance to index 2 to avoid conflicts.
	- Don't default initialise the debug code string for Metal shaders or it won't print out the actual code....

	- Removed different logic to determine if translucency after DOF was enabled, and centralized it into a single function: FSceneViewFamily::AllowTranslucencyAfterDOF()
	- FSceneRenderTargets::FinishRenderingSeparateTranslucency() now only resolves a single view, allowing better Begin/Finish scopes.
	- Renamed FSceneRenderTargets::SeparateTranslucencyDepthRT into FSceneRenderTargets::DownsampledTranslucencyDepthRT since this one is only allocated when rendering in downsampled mode.
	- Standard translucency is now rendered in the same resolution than translucency after DOF. (downsampled or full resolution)
	- Removed RenderTranslucencyParallel and merged it's logic into RenderTranslucency. Renamed DrawAllTranslucencyPasses to RenderViewTranslucency and added a parallel version RenderViewTranslucencyParallel.
	- Moved all debug draw logic (VisualizeLPV, ViewMeshElements and SimpleElementCollector) to a common place.
	- New option "r.AllowDownsampledStandardTranslucency" to control the downsampling of standard translucency. Affect blend module materials

	#jira UE-41979
	Should never be crashing there, unless the mesh is changed after Init of the effect instance; this change safeguards against the number of mesh sections (and hence materials) changing after creation of the dynamic data to avoid the crash.

Change 3407451 on 2017/04/25 by Daniel.Wright

	Fixed Indirect Lighting Cache updates caused by capsule indirect shadows forcing point samples, breaking primitives using ILCQ_Volume

Change 3407452 on 2017/04/25 by Daniel.Wright

	Added r.AOJitterConeDirections, although disabled by default because it requires the temporal filter to be much stronger

Change 3408397 on 2017/04/25 by Daniel.Wright

	ViewFamily.bRealtimeUpdate is set to false if Slate is throttling (like when toggling show flags).  Volumetric fog discards the temporal history when not realtime, so you can see changes immediately.

Change 3408428 on 2017/04/25 by Daniel.Wright

	Changed 'r.AOMaxObjectsPerCullTile' default back to 512 as 256 causes artifacts with RTDF shadows

Change 3409764 on 2017/04/26 by Daniel.Wright

	Force dumping shader debug info for Global shaders when r.ShaderDevelopmentMode is enabled.  Most of the shaders you want to look at in a GPU capture are global shaders, and global shaders create few debug files.  'recompileshaders global' time 35s -> 38s for SM5.

Change 3411659 on 2017/04/27 by Daniel.Wright

	[Copy] Set Xbox One engine default screen percentage to 83.33 (1600x900), as ESRAM choices are dependent on this

Change 3411660 on 2017/04/27 by Daniel.Wright

	[Copy] Global distance field composite shader has a version for each flattened axis, which improves efficiency when updating a slab which is what camera movement typically causes

Change 3411667 on 2017/04/27 by Daniel.Wright

	[Copy] Discard distance field AO history buffer if it doesn't match the new buffer size.  This prevents reading uinitialized data after a scene render target resize.

Change 3411668 on 2017/04/27 by Daniel.Wright

	[Copy] Better indirect capsule shadow draw event info

Change 3411669 on 2017/04/27 by Daniel.Wright

	[Copy] Pass down FeatureLevel to AddSubjectPrimitive and GatherShadowsForPrimitiveInner instead of calling the scene's virtual function.  Showed up prominently in a sampling profile.

Change 3411755 on 2017/04/27 by Daniel.Wright

	[Copy] Occlusion queries are now always done before the base pass if a nearly full prepass is being used(DDM_AllOccluders or DDM_AllOpaque)
	* Removed r.OcclusionQueryLocation

Change 3411827 on 2017/04/27 by Daniel.Wright

	[Copy] Much cheaper implementation of IsForwardShadingEnabled which showed up prominently in sampling profiles - inlined function and no more unnecessary thread safety overhead

Change 3411829 on 2017/04/27 by Daniel.Wright

	Added an ensure to console manager when doing FindTConsoleVariableData* on a FAutoConsoleVariableRef

Change 3411837 on 2017/04/27 by Daniel.Wright

	[Copy] Worked around slow memcpy's being used to sort FSortedLightSceneInfo

Change 3411838 on 2017/04/27 by Daniel.Wright

	[Copy] Skip tracking MaterialRenderProxyMap on cooked platforms

Change 3411843 on 2017/04/27 by Daniel.Wright

	[Copy] Fixed r.ParallelShadows on PS4 and enabled by default engine-wide (saves 5ms RT with CSM)
	* Gnm was not tracking DepthClearValue when a depth target was set but not cleared
	* Gnm has a bug where TargetsNeedingEliminateFastClear does not persist across commandlist breaks.  Moved FinishRenderingGBuffer before RenderShadowDepthMaps to workaround (accidentally not in this changelist)
	* Shadow depth rendering was not using BindClearMRTValues to populate GNM parallel commandlist TargetsNeedingEliminateFastClear values

Change 3411873 on 2017/04/27 by Daniel.Wright

	[Copy] Deferred uniform expression caching.  Setting multiple parameters on a material only causes its uniform expressions to be recached once.
	* 280 calls to CacheUniformExpressions -> 120 during Fortnite combat (6.5ms -> 3.4ms)

Change 3411891 on 2017/04/27 by Daniel.Wright

	[Copy] GatherShadowPrimitives optimizations
	* Total GatherShadowPrimivies went from 2.3ms -> 1.3ms on PS4 with these changes in GPUPerfTest (duplicated 3x)
	* Much flatter primitive octree (16 -> 256 max primitives)
	* Primitives are culled against the shadow frustum before FPrimitiveSceneInfo or FPrimitiveSceneProxy are dereferenced in FilterPrimitiveForShadows
	* FilterPrimitiveForShadows work is done in a ParallelFor.  Primitive octree nodes are processed in different jobs.
	* StaticMeshWholeSceneShadowBatchVisibility now only stores entries for meshes with bRequiresPerElementVisibility (landscape).  Previously it was allocating and zeroing 500Kb 3x per frame (main view + 2 cascades) which cost ~.8ms on PS4.

Change 3412192 on 2017/04/27 by Michael.Trepka

	Fixed Clang compile errors in FortniteGame, partial copy of CL 3313426

Change 3412547 on 2017/04/27 by Daniel.Wright

Change 3431667 on 2017/05/09 by Daniel.Wright

	Volumetric fog now supersamples lighting when the history is not available, reducing noise on areas that just came on-screen or after a camera cut.
	* The number of samples is controlled by r.VolumetricFog.HistoryMissSupersampleCount, defaults to 4, cinematic scalability uses 16
	* Under fast camera movement, volumetric fog cost went from 1.79ms -> 1.97ms with 4 samples, on a 970GTX

Change 3432366 on 2017/05/10 by Richard.Wallis

	Fix for MetalRHI Asserts When Using "Profile GPU" With RHI-Thread/Parallel-Execution.  Don't insert events when not in RHIThread or the actual single-threaded-render thread.

	#jira UE-36006

Change 3432367 on 2017/05/10 by Richard.Wallis

	Fix for Metal ReStartRenderPass assert with profiling.  macOS metal asserts when using "profileGPU" even with -norhithread argument set.

	Added no action to the allowed render pass restart store actions for the depth buffer avoiding the assert.  Interested to know the details if this is not a valid assumption to make - throwing away the depth buffer after a render pass I think would be a common case.

	#jira UE-44322

	Fix for shared Material Native Shader Libraries Don't Function With Iterative Cooking.   Keep latest versions of shader byte code in native shared material packaged build in an intermediate directory than can be reused on a later iterative cook.

	- Doesn't handle deletion of the intermediate directory contents.  Assumed to be a higher level requirement on non iterative cook flag.

Change 3433619 on 2017/05/10 by Daniel.Wright

	Skip recapturing reflection captures when PropagateLightingScenarioChange is being called for a level unload.  This leaves stale results in reflection captures around when hiding a level in the editor, but avoids the double recapture that happens when swapping lighting scenarios in game, and the unnecessary reflection capture update when exiting PIE.

	Crash fix.
	Issue found in https://udn.unrealengine.com/questions/355944/crash-in-fdynamicspriteemitterdatagetdynamicmeshel.html

	Particle proxies would have stale material resource pointers if the material is changed while the system was invisible.
	If the old material is freed during this time, the next time the system renders it will crash.

Change 3437367 on 2017/05/12 by Brian.Karis

	Added Apple override allocator macro - each command encoder type needs it's own allocator queue.

Change 3444787 on 2017/05/17 by Daniel.Wright

	Fixed DBuffer decal default normal (used when DBuffer decals enabled, but not decals rendered) not reconstructing zero properly, adding -.008 to WorldNormal which then caused artifacts with forward lighting specular on materials with roughness near 0.

MAJOR FEATURES + CHANGES
==========================

Change 3358140 on 2017/03/22 by Rolando.Caloca

	DR - Fix copy to cube face
	- Compile fix when using dump layer
	- Add new error enum

Change 3358301 on 2017/03/22 by Mitchell.Wilson

	Initial check in of LODs in InfiltratorForward. First pass on optimization in level. Adding a visibility track for SceneCapture2D in tunnel section.

Change 3358477 on 2017/03/22 by Mitchell.Wilson

	Updating Skeletal Mesh DPW_Robot_Export to resolve screen size being too low for LOD1. Cleaned up LOD1 which was showing some visible popping when transitioning.

Change 3358529 on 2017/03/22 by Mark.Satterthwaite

	Globally disable clang's "constant-logical-operand" warning when running under Distcc - it is much easier and less invasive than constantly fixing the code.

Change 3358745 on 2017/03/22 by Mark.Satterthwaite

	Disable another warning (parentheses-equality) under Distcc because again the separation of preprocessing from compilation means it turns up where it isn't expected.

Change 3358837 on 2017/03/22 by Joe.Graf

	Merge of pull request #3214 for the RenderDocPlugin

	#CodeReview: matt.kuhlenschmidt, marcus.wassmer
	#rb: marcus.wassmer

Change 3367838 on 2017/03/28 by Richard.Wallis

	Updated items from original shelved version by Mark Satt:

	- Added MetalBackend.cpp to change main function string to have an initial crc + code length zero's

	**Description below taken from Mark Satt's original verison of this in CL3343280**

	Updated for Dev-Rendering's PSOs & integrates Richard's work on RHI shader libraries.

	Replace the FShaderCache's cook-time binary shader cache with Dmitriy Dyomin's standalone FShaderCodeLibrary that saves all shader byte-code arrays to files named by the FSHAHash. This de-duplicates shaders so we only ever store the byte code once. Includes optional support for generating a platform specific library file - which Metal implements to provide a single Metal library. The platform-native implementation can perform more de-duplication and in the case of Metal has lower file overheads and will compress more efficiently.

	- All of the support code for the FShaderCache's cook caching is gone, which affects all platforms. The FShaderCodeLibrary is currently  supported by Cook-By-The-Book but can be used with iterate or child cookers - only DLC cooking requires further work.
	- With further modifications it should be possible to support Cook-on-the-Fly as well (output directories would be needed in FShaderCodeLibrary::InitForCooking) and the file-access pattern should be changed to use async. IO so that Material loading is not considered complete until all required byte-code arrays are loaded into the FShaderCodeLibrary.
	- For Metal archiving shaders this way will compile with debug information and the FShaderCodeLibrary, with some help from extensions to IShaderFormat, will save the debug information out into separate files during cooking - these can then be used to debug the game without having to locally recompile, recook & repackage but the shipped byte-code is stripped. Global shader caches are also subject to de-duplication in the library in order to support Metal's shader stripping.
	- File Move operations need to respect the 'Replace' flag - for FShaderCodeLibrary to work we need Move to be atomic.
	- This bumps the object version and will cause all content to recook.
	- Native library support is optional - only Metal currently implements one, but so could Vulkan and D3D12. For Metal the big advantages are further de-duplication where different materials generate the same MetalSL text but a different FSHAHash, that the single Metal library has lower overhead and that as a single file it all compresses far better (esp. with LZMA - 5x smaller).

Change 3367854 on 2017/03/28 by Mark.Satterthwaite

	Don't track or record draw call resources for non-OpenGL shader platforms in the shader-cache as it is unnecessary and makes it slower on the CPU than it needs to be.

Change 3372436 on 2017/03/30 by Uriel.Doyon

	Added flags in UPrimitiveComponent to keep track of its state in the streaming manager.
	This allows to avoid unnecessary callback and processing in begin destroy reattach and being destroy logic.

	Removed the limitation of only processing UMeshComponent when handling spawed primitive.
	This releases the level manager from having to manage dynamic primitives.
	This improves performance by not having to manage dynamic references in the level manager.

	Primitives managed as dynamic now have a callback when ever their proxy is udpated, handling
	many cases automatically where previously a manual callback to notify would have been required.

	Fixed an issue where primitives with no reference to streaming textures would loose they dynamic state
	because of lack of references in the streamer.

	Future Work
	- This was done before Engine PSO were in so this now needs a refector in the recording and playback on pipeline states instead an emulate PSO in OpenGL Driver.
	- Remove FShaderCacheState and replace the logic with FGraphicsPipelineStateInitializer which should be able to record from the RHI current pipeline state
	- This would reduce the Locking required as it's naturally per thread/context and only the final record would need a lock

	Partial code tidy up.

Change 3310187 on 2017/02/17 by Chris.Bunner

	Preserve constant expressions rather than always casting after translating a material attribute. Losing the notion of constant means we can't correctly detect used properties and falsely enable e.g. PDO. Happened because of the incorrect component masks in BreakMaterialNodes which then had to be downcast to the correct type which is done as an inline fragment rather than swizzle expression.

	#jira UE-41594

Change 3310215 on 2017/02/17 by Chris.Bunner

	[Copy] Added 'r.AOListMeshDistanceFields' which dumps out mesh distance fields sorted by memory size, useful for directing content optimizations

Change 3333705 on 2017/03/06 by Daniel.Wright

	[Copy] Mesh distance fields are now 8 bit fixed point by default, but can be changed back to 16 bit floating piont with a project setting.
	* 8 bit uses half memory but introduces error for thin surfaces or large meshes.

Change 3333721 on 2017/03/06 by David.Hill

	DecalProxy:
	Copy float FadeScreenSize to FDeferredDecalProxy for use in the render thread.  This avoids  pointer chasing to the UDecalComponent (game thread component).

Change 3333772 on 2017/03/06 by Daniel.Wright

	[Copy] Scene motion blur data is only updated for the main renderer frames.  Fixes scene captures and planar reflections breaking object motion blur.

Change 3333790 on 2017/03/06 by Daniel.Wright

	Non-editor compile fix

Change 3333836 on 2017/03/06 by Daniel.Wright

	[Copy] Workaround for gobal distance field volume textures being bloated by 4x on PS4 due to the recommended tiling modes.  They now use a 2d tiling mode which avoids the bloat, saving 96Mb.

Change 3333869 on 2017/03/06 by Daniel.Wright

	[Copy] Volumetric Fog using a volume texture mapped to the camera frustum
	* Volumetric fog can be enabled on an Exponential Height Fog component with additional controls
	* Lights have a VolumetricScatteringIntensity
	* New cvars r.VolumetricFog, r.VolumetricFog.GridPixelSize, r.VolumetricFog.GridSizeZ, r.VolumetricFog.DepthDistributionScale
	* Lighting features supported:
	   * Directional light with CSM and a light function
	   * Point / spot lights without shadows / light functions / IES profiles
	   * Skylight with occlusion from distance fields
	* Analytical height fog covers the view range past where the volumetric fog ends
	* Temporal reprojection is used on the volumetric fog scattering and extinction to achieve stability
	* Translucency integrates properly into volumetric fog
	* Height fog StartDistance is not supported by volumetric fog and should be set to 0.

Change 3333894 on 2017/03/06 by Daniel.Wright

	[Copy] Initialize GDummyVolumetricFogGlobalDataUniformBuffer outside of parallel rendering

Change 3333902 on 2017/03/06 by Daniel.Wright

Change 3333908 on 2017/03/06 by Daniel.Wright

	[Copy] Volumetric materials
	* Added new material domain Volume, which can output Scattering, Absorption and Emissive.  All properties are in world space densities.
	* Particle systems using the Volume domain are voxelized based on their ParticlePosition and ParticleRadius
	* Volumetric fog integration is now energy conservative - scattering is integrated against transmission over the depth of each slice.
	* Added bOverrideLightColorsWithFogInscatteringColors to exponential height fog, which can be enabled to make Volumetric Fog match Height fog more closely

Change 3334134 on 2017/03/06 by Daniel.Wright

	[Copy from Michael Trepka] Added Embree 2.14.0 and changed MeshUtilities to use it as this solves issues with Embree leaking TLS keys. UnrealLightmass is still using older Embree 2.7.0 until we can find time to properly test it with the new version. Also, invalidated distance field DDC to force it to rebuild with updated Embree.

	* Forward lighting of local lights can be forced with 'r.VolumetricFog.InjectShadowedLightsSeparately 0'

MAJOR FEATURES + CHANGES
==========================

Change 3250856 on 2017/01/09 by Daniel.Wright

	Only showing instruction count for 'Base pass shader' now

Change 3250943 on 2017/01/09 by Rolando.Caloca

	DR - Async Compute PSO creation

Change 3251036 on 2017/01/09 by Rolando.Caloca

	DR - Add r.AsyncPipelineCompile
	- Dispatch on any thread
	- Wait for completion event

Change 3251058 on 2017/01/09 by Ben.Woodhouse

	Fix for PSO creation D3D error with NumRenderTargets. Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN)
	#jira UE-40332

Change 3251141 on 2017/01/09 by Ben.Woodhouse

	Duplicated from Fortnite CL 3243458:
	D3D12 memory optimization -  The d3d12 buddy suballocator  is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory.

	On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage.

	Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX

Change 3251142 on 2017/01/09 by Ben.Woodhouse

	Duplicated from Fortnite 3243496
	memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time.

Change 3252323 on 2017/01/10 by Rolando.Caloca

	DR - Gfx async PSO creation prep

Change 3252474 on 2017/01/10 by Daniel.Wright

	Back out bulk data for distance fields from cl 3241990 which causes distance fields to be corrupt in Fortnite

Change 3252790 on 2017/01/10 by Daniel.Wright

	Added InscatteringColorCubemapAngle to exponential height fog

Change 3252843 on 2017/01/10 by Uriel.Doyon

	Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways.
	The bound defrag is now done outside of the async work logic.

Change 3252866 on 2017/01/10 by Mark.Satterthwaite

	Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future.
	#jira UE-40357

Change 3254511 on 2017/01/11 by Rolando.Caloca

	DR - PSO stats

Change 3255958 on 2017/01/12 by Mark.Satterthwaite

	Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed.
	#jira UE-40554

Change 3256329 on 2017/01/12 by Olaf.Piesche

	#jira UE-38615

	Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

Change 3256371 on 2017/01/12 by Uriel.Doyon

	Reenabled texture streaming bound defrag as the fix is in CL 3252843

Change 3257032 on 2017/01/13 by Daniel.Wright

	Added fastClamp to fastmath.usf

Change 3257111 on 2017/01/13 by Daniel.Wright

	Disabled bAffectDistanceFieldLighting on DefaultPawn, fixes VisualizeMeshDistanceFields in game

Change 3257112 on 2017/01/13 by Daniel.Wright

	DFAO optimizations
	* Changed the culling algorithm to produce a list of intersecting screen tiles for each object, instead of the other way around.  Each tile / object intersection gets its own cone tracing thread group so wavefronts are much smaller and scheduled better.  3.63ms -> 3.48ms (.15ms)
	* Replace slow instructions in inner loop with fast approximations (exp2 -> sqr + 1, rcpFast, lengthFast) 3.25ms -> 3.09ms (.16ms)
	* Moved transform from world to local space out of the inner loop (sample position constructed from local space position + direction) 3.09ms -> 3.04ms
	* Compute shader for ClearUAV 3.04ms -> 2.62ms (.42ms)

Change 3257113 on 2017/01/13 by Daniel.Wright

Change 3257326 on 2017/01/13 by Uriel.Doyon

Change 3257448 on 2017/01/13 by Daniel.Wright

	Removed legacy features Distance Field Specular Occlusion, Distance Field Surface Cache AO, PreCullTriangles

Change 3257616 on 2017/01/13 by Daniel.Wright

	Distance field mesh visualization now uses a cone containing the entire tile to cull objects with, making the results stable

Change 3257657 on 2017/01/13 by Daniel.Wright

	Mesh distance fields are stored zlib compressed in memory until needed for uploading to GPU
	* 81Mb of backing memory -> 32Mb in GPUPerfTest, atlas upload time 29ms -> 893ms

Change 3258063 on 2017/01/14 by Rolando.Caloca

	DR - vk - Refactor descriptor set reuse in prep for more changes

Change 3258827 on 2017/01/16 by Daniel.Wright

	Global distance field update regions are clipped against others to reduce redundant updates.

Change 3258959 on 2017/01/16 by Benjamin.Hyder

	Updating Planar Reflection example material in TM-Shadermodels

Change 3259270 on 2017/01/16 by Daniel.Wright

	[Copy] 'r.MSAACount 1' now produces no MSAA or TAA.  'r.MSAACount 0' can be used to toggle TAA on for comparisons.

Change 3259652 on 2017/01/16 by Uriel.Doyon

	Better support for static primitive becoming dynamic.

Change 3260107 on 2017/01/17 by Ben.Woodhouse

	Fix FMonitoredProcess to prevent infinite loop in -nothreading mode
	#jira UE-40717

Change 3260594 on 2017/01/17 by Daniel.Wright

	Added a new global distance field (4x 128^3 clipmaps) which caches mostly static primitives (Mobility set to Static or Stationary)
	* The full global distance field inherits from the mostly static cache, so when a Movable primitive is modified, only other movable primitives in the vicinity need to be re-composited into the global distance field
	* Global distance field update cost with one large rotating object went from 2.5ms -> .2ms on 970GTX and 4.6ms -> .3ms.  Worst case full volume update is mostly the same.
	* Adds 12Mb for the new volume textures

Change 3260956 on 2017/01/17 by Daniel.Wright

	Structured buffers for DF object data
	* Full global distance field clipmap composite 3.0ms -> 2.0ms due to scalarized loads

Change 3261296 on 2017/01/17 by Daniel.Wright

	Exposed MaxObjectsPerTile with 'r.AOMaxObjectsPerCullTile' and lowered the default from 512 to 256, saves 17Mb of object tile culling data structures
	Removed unnecessary UAV transitions preventing object and global cone tracing from overlapping, saves ~.1ms

Change 3262036 on 2017/01/18 by Ben.Salem

	V0 of Perf monitor plugin for easily consumable stat csvs. With plugin enabled, enter PerformanceMonitor help into the console to get usage details.

Change 3262056 on 2017/01/18 by Chris.Bunner

	Remove inverse tonemapping when rendering HDR output.
	#jira UE-40728

	DR - Add missing SetStencilRef() and SetBlendFactor() on most RHIs
	- Fix hash for PSOs

Change 3263674 on 2017/01/19 by Chris.Bunner

	PR #3144: Improved error messages (Contributed by DarkSlot)
	#jira UE-40835

Change 3264150 on 2017/01/19 by Ben.Woodhouse

	Add support for single threaded in FMonitoredProcess. Deprecated IsRunning() in favour of a new Update() method because polling IsRunning is not compatible with -nothreading mode
	#jira UE-40841

Change 3264153 on 2017/01/19 by Ben.Woodhouse

	Integrate latest changes from MS-DX12 CLs 3231395-3262526

	- Added WinPixEventRuntime.tps
	- Includes PIX support, various optimizations (saved 1.3ms in testbed scene)

	CL 3262343:
	Fix depth testing on translucency not working correctly after cl 3231395. This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes:
	 - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case.

	CL 3231395:
	  Update D3D12 RHI:
	 - Fix deferred MSAA path in RHI
	 - Add Pix3.h support
	 - Cleanup SetName usage and remove it from shipping builds.
	 - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value.
	 - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64
	 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version.
	 - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident.

Change 3264251 on 2017/01/19 by Mark.Satterthwaite

	Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions.
	#jira UE-40803

Change 3264642 on 2017/01/19 by Daniel.Wright

	Raised GMaxShadowDepthBufferSizeX to max texture resolution on most platforms, was previously 4096.

	#tests recompiled and preflighted

	Fix bad declaration.
	#3055

Change 3266656 on 2017/01/20 by Mark.Satterthwaite

	Changes to the FShaderCache to restore it and extend it to optionally report on shader de-duplication when generating a binary shader cache (Console Variable: r.BinaryShaderCacheLogging).

	Duplicate & amend CL #3266053 from Trepka:
	Fixed issues with shader cache not working properly with Mac Metal (but it still requires -norhithread to work at all). Enabled the shader cache by default if RHI thread is disabled.

	Amend & integrate RCO's CL #3197085.

Change 3267741 on 2017/01/23 by Rolando.Caloca

	DR - Detect duplicated shader and pipeline types

Change 3268600 on 2017/01/23 by Uriel.Doyon

	Added missing r.Streaming.MaxEffectiveScreenSize config to base texture scability settings.
	Integrated CL 3227368 from Orion stream
	Enabled r.Streaming.UsePerTextureBias by default as this has been tested in Orion for several months.
	Fixed issue with the  InvestigateTexture command which could return invalid reference depending on the timing,
	Added th MaxEffectiveScreenSize settings in the investigate texture command.

Change 3269512 on 2017/01/24 by Richard.Wallis

	Fix for shader binary cache uncompress data size during internal shader log.

Change 3271237 on 2017/01/25 by Ben.Woodhouse

	#jira UE-40980
	#udn 325525

	Fix uniform buffers for mesh particles; these should really be on the mesh collector, so allocating them as a one frame resource is safe

Change 3271594 on 2017/01/25 by Ben.Woodhouse

	ESRAM support stage 1:
	Implemented noncontiguous ESRAM page allocator replacing XgMemoryLayout API. The allocator allocates non-contiguous ranges of pages and maps them onto a contiguous virtual address range.
	Unlike the previous implementation, this allocator frees pages for reuse when resources are destroyed
	Note: issues with deferred deallocation may prevent reuse in many cases - that will be addressed in the next stage
	Support for the old allocator is still available (for now) via the define NEW_ESRAM_ALLOCATOR
	#fyi rolando.caloca

	DR - Update shader version

Change 3273138 on 2017/01/26 by Ben.Woodhouse

	Fix merge issue with MonitoredProcess.cpp (this arose from an integration made as an edit in dev-rendering, which confused perforce when the change was subsequently integrated from main)

Change 3122543 on 2016/09/13 by Ben.Woodhouse

	#jira UE-35878

Change 3122544 on 2016/09/13 by Ben.Woodhouse

	Shadow stencil optimisation with cvar (enabled by default)

	Avoids redundant clearing the stencil buffer for per-object and pre shadows by zeroing the stencil during testing, following discussion on UDN.

	This means we don't benefit from Hi Stencil on GCN for the shadow projection draw calls, but it's still faster in all the cases I could find, including for the player character where the bounding box is quite large. (Note: early stencil still works fine, according to PIX)

	Shadow projection GPU time profiling :
	Test map with 35 characters, stationary directional light
	  - 4ms-2ms on XB1
	  - 2.5ms to 0.9ms on PC (r9-390X)
	  - 3ms-2ms on PS4

	Paragon PS4 (roughly 20% reduced - from ~0.39ms)

	Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))).

	Fix for ensure fail when initializing point light shadowmaps.

	This came about because cubemap rendertargets always have Extents of (Resolution, 0). The Y component was implicitly used to determine if it was a cubemap, which is odd... The fix was to make the definition explicit via a flag and initialize both the X and Y parameters.

	I suspect the ensure started happening recently due to a more recent change, but fixing the underlying logic seems like the correct fix.

Change 3131625 on 2016/09/19 by Mark.Satterthwaite

	Inside MetalRHI add an optional cache for disposed texture objects so we may reuse them - controlled by CVAR rhi.Metal.TextureCacheMode which must be set prior to running as it can't be changed at runtime. Settings: 0 = off, 1 (default) = will attempt to reuse private memory texture objects within the frame they are released otherwise they are disposed of as before. Setting 2 extends the caching to all textures - though Managed/Shared textures cannot be reused until after the frame in which they were released has been processed on the GPU. In this mode id<MTLTexture> objects are never returned to the OS so in order to conserve VRAM calls to setPurgeableState are made to allow the driver to reclaim unusued memory if required.

	Use set*Bytes to handle uploading buffers < 4Kb when available - this is faster than lots of small Metal buffers and reduces the amount of GPU heap fragmentation.

	Duplicate CL #3137164:
	Add stats to track exactly how many command buffers are allocated and committed each frame to work out why Fortnite on AMD is hanging, which turns out to be because each texture update/reallocation ends up in its own command-buffer. This needs to be rethought to pack these into fewer command buffers with the same synchronisation requirements to minimise command-buffer splits but for now we'll just make the default sufficiently large that we shouldn't see the hang until the work is done. Also ensure that command-buffer failure is always fatal - there is no way to recover or continue if a command-buffer fails.

Change 3140360 on 2016/09/26 by Daniel.Wright

	Lighting Scenarios and lightmaps moved to separate package
	* Levels can be marked as lighting scenarios (eg Day, Night).  Lighting is built separately for each lighting scenario with actors / lights in all other scenario levels hidden.  Only one lighting scenario level should be visible at a time in game, and its lightmaps will be applied to the world.
	* Most outputs of the lighting build now go into a separate _BuiltData package.  This improves level Save and AutoSave times as the separate package will only be dirtied after lighting rebuilds.
	* If a lighting scenario is present, all lightmaps are placed inside it's _BuiltData package.  This means that only the currently loaded lighting scenario's lightmaps will be loaded (Day or Night, but not both).  This also means that lightmaps for a streaming level will not be streamed with it.
	* For backwards compatibility, existing lightmaps are moved to a new _BuiltData package on load.
	* Reflection captures and precomputed visibility were not moved to the separate package.  Reflection captures are force updated on load of a lighting scenario level, which can increase load times.

	The density are computed by the engine but can be overridden by the user in the material tabs.

	Texture streaming intermediate component data is now per material instead of per lod-section.

	New ViewModeParam in FSceneViewFamily allowing context specific param per viewmode.
	This is currently used to show which UV channel and which texture index is being
	shown in the texture streaming accuracy viewmodes.
	This replaces r.Streaming.AnalysisIndex

	Renamed texture streaming viewmodes:
	MeshTexCoordSizeAccuracy -> MeshUVDensityAccuracy
	MaterialTexCoordScalesAccuracy -> MaterialTextureScaleAccuracy
	MaterialTexCoordScalesAnalysis -> OutputMaterialTextureScales

	Improved UV density computation and viewmode.

	LightmapUVDensity is now computed separately from UVChannel Density.

	Fixed texture streaming for instanced static mesh component and derived types.

Change 3143822 on 2016/09/28 by Arne.Schober

	DR - Refactoring of the ViewMatrices. Moved the Derived Matrices into the FViewMatrix struct. Made all members private do emphasize the static constness of that struct after creation. Renamed the heavy weight members on this struct to Compute*. Methods that modify The ViewMatrices have been renamed to Hack* to discurage their use in the future until a better solution for those problems is found. The ViewMatrix modification is especially misleading because it only changes the State of the ViewMatrices to read their Position from the Material Editior as if coming from the Lightsource (mainly for manual bilboards) as well as doing someting similar to generate CPU bilboards for shadows.

	Fix AbilitySystemComponent not ticking while playing a montage, and ticking when we're not playing a montage

	Here's the issue in the version of the code prior to this checkin:
	- UpdateShouldTick calls GetShouldTick, which checks the value of RepAnimMontageInfo.IsStopped
	- When we call UpdateShouldTick within AnimMontage_UpdateReplicatedData, we haven't set RepAnimMontageInfo.IsStopped yet to the correct value
	- So when we aren't playing any montages but are starting a new one, we were saying we shouldn't tick
	- It also means if we were playing a montage, and then stop, we'll start ticking
	- Ticking calls AnimMontage_UpdateReplicatedData, which should be called while we're playing

Change 3078122 on 2016/08/04 by Dmitry.Rekman

	Linux: treat abort() / SIGABRT as crash.

	- Rationale: certain code not under our control (most notably, stack smashing protector) may call abort(), which would previously terminate the engine without any chance to even enter the crash handler.
	- Rewrote RequestExit() because it used abort() itself.
	- Also removed -fstack-protector. The logic behind this is: stack protector calls abort() on detecting a smash (which is suspected to contribute to missing reports), but does it at an inappropriate place, that causes stack unwinding to crash later.  As bad as it sounds, it may be better to allow stack to be corrupted and crash later - hopefully outside of libc code - to some other reason.

	OR-26580 CRASH: FXAudio2SoundSource::GetChannelVolumes - Silent Crash during gameplay

	- Removed voice operation set since it was causing crashes when stopping voices. Still a good idea, but need to make sure the async OnBufferEnd and stopping an FSoundSource can work together.
	- Added a proxy object that wraps the FAsyncTask used for async decoding. Calling IsDone() and EnsureCompletion() can't happen at the same time from different threads now.

	Engine: Refactored FPS chart creation to make it modular so many performance data consumers can be active at once, allowing greater flexibility and decoupling game analytics from FPS chart exec commands
	- IPerformanceDataConsumer is an interface for all consumers of per-frame performance tracking data, and instances can be registered/unregisted with the engine using AddPerformanceDataConsumer/RemovePerformanceDataConsumer
	- The implementation of the 'standard' frame time and hitch histogram tracking is FPerformanceTrackingChart, while the per-frame logging .csv is split into a separate FFineGrainedPerformanceTracker class.
	- The calculation of frame time breakdowns and hitch detection now occur as long as at least one IPerformanceDataConsumer is registered
	- Internally the code has been cleaned up a bit to use FHistogram for data storage instead of custom binning code

	Upgrade Notes:
	- DumpFPSChartAnalytics has been removed, games that used it should switch to creating their own instance of FPerformanceTrackingChart and call DumpChartToAnalyticsParams on it directly
	- In general games should have no reason to programmatically call GEngine->StartFPSChart anymore, instead creating their own instance (this prevents conflicts when using the engine console commands)
	- HTML output for stopfpschart is now generated to a single file rather than two duplicate files (using both map name and capture time as part of the file name)
	- Removed PauseFPSChart, IsFPSChartActive, and GetFPSChartBoundByFrameCounts to reflect that the GEngine instances aren't meant for external use (Start/Stop are left public for automated testing that wants to use them to do logging, but may also be moved private in the future)

	Paragon:
	- Updated to use a separate FPerformanceTrackingChart for gameplay versus in-game menus and removed the duplicated code and GameThreadHitchChart event
	- Removed partial USE_SERVER_PERF_COUNTERS code in ChartCreation.cpp, splitting it out into a separate observer, which currently lives in Paragon but will be moved to shared code in a separate checkin. The code was only useful in the first place along with other Paragon-side code that was consuming it.

Change 3067560 on 2016/07/27 by Aaron.McLeran

	OR-26322 Client Hang in FXAudio2EffectsManager::SetReverbEffectParameters

	- Only applying reverb parameters if they've changed from previous reverb params to avoid unnecessarily spamming the XAudio2 API call
	- using xaudio2 operation sets to ensure that voice and effect params are executing in sequence
	- only calling destroy voice after all voice and effect changes have been committed to avoid destroy voice interfering with those commands
	- Don't call EnsureCompletion on pending async tasks on teardown

	#rb Jeff.Campeau
	#tests play paragon with change, notice no changes to audio behavior, no crashes. Created testmap with several reverb zones and demonstrated reverb effect transitions

	- Added O(1) getters for total sample counts and sum of all measurements
	- Removed encapsulation-breaking SetBinCountByIndex / SetBinSumByIndex

Change 3066681 on 2016/07/27 by Frank.Gigliotti

	Camera anim field of view fix;

	* The FOV is now reset on the PlayerCameraManager camera actor when it's initialized.  This fixes cases of stale FOV values after playing camera anims that don't end with the FOV at it's base value.

	* Base FOV can now be edited in the CameraAnim properties.  This allows you to specify what the FOV keys are relative to.  Previously it was always using a base FOV of 90 degrees.

Change 3073689 on 2016/08/02 by Ben.Woodhouse

	Improved skin postprocess - support for full resolution, with diffuse/spec lighting combined into single RGBA (sharing chroma)

	Full res lighting gives less temporal AA flickering, sharper diffuse and specular lighting in the surface (since this is now at full resolution), faster postprocessing if using a 64-bit rendertarget (on NV 980Ti).

	Checkerboard rendering is controlled via the r.sss.checkerboard cvar. - 0 is off/full res, 1 is checkerboard, 2 is automatic based on scenecolor (non-checkerboard requires 64bit or more rendertarget w/separate alpha)

	Tested/profiled on PC, PS4

Change 3075969 on 2016/08/03 by Uriel.Doyon

	Material GUIDs are not updated anymore when parents or textures change.
	Lighting now uses a hash built from the list of parents, textures and shader functions.

	Removes integer BBS random number generators. Fewer instructions, but too slow to use (see 1.7x perf boost above)

Change 3077884 on 2016/08/04 by Daniel.Wright

	Lighting channels can now be edited on components with static mobility, since dynamic lights can still affect them

Change 3078994 on 2016/08/05 by Simon.Tovey

	Fix for UE-34241
	Scene proxy ptr was being cached during a downcast.
	Inside a call to CreateDynamicData, CheckMaterialUsage_Concurrent() was causing the scene proxy to be recreated an so the cached ptr was stale.
	I've fixed the immediate issue but recreating the scene proxy here doesn't seem great. Maybe CheckMaterailUsage() should be rethought a bit.

	MIGRATING FIX @ Request

	Off by 1 error on reflection roughness calculation affecting 4.12. When I hoisted the max mip index i did a -1 on both sides(c++ & hlsl). This is the simplest hotfix. In 4.13 I'll remove the shader instruction and only do the "-1" in c++ this 1 less shader instruction.

Change 3009028 on 2016/06/10 by Daniel.Wright

	Shadow depth refactor
	* Shadow setup and render target allocation now happens in InitViews, and shadow depth rendering happens at one spot in the frame
	* This provides control over where shadow depths are rendered for things like async compute, and allows easy atlasing of shadowmaps for forward shading
	* The 33Mb of shadow depth buffers in FSceneRenderTargets has been removed, and shadow depth buffers are now allocated as needed
	* A large amount of duplicated code to handle each shadow type has been combined
	* Cleaner parallel rendering: no more view hacking for the shadow depth pass, no more shadow depths in the middle of translucency
	* 'vis ShadowDepthAtlas' or 'vis WholeSceneShadowMap' must now be used to visualize the shadow depth textures

Change 3013736 on 2016/06/14 by Daniel.Wright

	Cached shadowmaps for whole scene point and spot light shadows
	* Controlled by 'r.Shadow.CacheWholeSceneShadows', defaults to enabled (7ms -> 1.5ms of shadow depths on Titan for ~20 lights)
	* Primitives with Static or Stationary mobility have their depths cached, as long as the light is not moving
	* Primitives with Movable mobility or using World Position Offset in their materials will not have their depths cached
	* Cached shadowmaps are copied each frame and then movable primitive depths composited
	* Fast paths exist for when there were no static primitives (skip cached shadowmap) or movable primitives (project directly from cached shadowmap)
	* 'r.Shadow.CacheWPOPrimitives' controls whether materials using WPO can be cached (default is off for correctness)
	* 'r.Shadow.CachedShadowsCastFromMovablePrimitives' can be used to force off all support for movable primitives, skipping the shadowmap copies (1.5ms -> 0ms of shadow depths for ~20 lights)

	Ripped out the quick hacky VM debugger I wrote a while back.
	Over complicated the VM and didn't do enough work to justify it.
	Will revisit debugging and profiling of VM scripts in future.

Change 3019691 on 2016/06/20 by Ben.Woodhouse

	Add a per-object shadow setting for directional lights (r.Shadow.PerObjectDirectionalDepthBias), which is independent of the CSM setting. Often a smaller bias is desirable on per-object shadows, where detailed self-shadowing is needed.

	This change also makes the CSM naming consistent with what the setting actually does (the old setting was named r.shadow.csm, although it affects per-object shadows as well as CSMs).

	#tests front end parties, being kicked from outpost lobby

Change 3013712 on 2016/06/14 by Bob.Tellez

	#UE4 Fix DrawNetDriverDebug crash during map transitions

Change 3013418 on 2016/06/14 by Mark.Satterthwaite

	Don't release Metal buffers directly into the buffer pool, instead defer this until the command-buffer is known to have finished. This prevents the CPU from trying to modify the buffer while the GPU is still reading it if the GPU has fallen so far behind the CPU and therefore eliminates one possible cause of invalid access on the GPU.
	#jira FORT-24510

Change 3013394 on 2016/06/14 by Mark.Satterthwaite

	Report Metal command-buffer failures in MetalQuery in the same way as MetalCommandList and make them fatal as well. This ensures that the game doesn't try to continue if the commands failed as that is unsafe.
	#jira FORT-24808

Change 3012977 on 2016/06/14 by Fred.Kimberley

Change 3012755 on 2016/06/14 by Bob.Tellez

	#JIRA FORT-113

Change 3011948 on 2016/06/13 by Mark.Satterthwaite

	Workaround a Fortnite crash on launch for Mac OpenGL - one or more shaders are using the bit-cast operators (asuint(), asfloat()) that aren't available with GLSL version 150. In order to use them the GLSL version must be 330 which means switching the version tag at runtime. There will be Mac GPUs on 10.10.5 which don't correctly implement these instructions so this really isn't a fix - that would be to change shaders to not use SM5-level instructions.

Change 3011659 on 2016/06/13 by Bob.Tellez

	#UE4 Better handling of checked state in SGameplayTagWidget::IsTagChecked. Checking direct child tags was not sufficient and also not needed since HasTag allows you to follow parent tags when checking for an explicit tag.

Change 3011647 on 2016/06/13 by Rob.Cannaday

	Fix for multiple account login not kicking previous logins
	Client was not parsing response from backend.  Client was expecting content-type to be "application/json" (using FString::Equals).  Backend was returning "application/json;charset=UTF-8".  Changed usage from FString::Equals to FString::StartsWith
	#jira FORT-25452
	#tests multiple account login, frontend only

Change 3011436 on 2016/06/13 by Nick.Cooper

	#UE4 - Added bRelativeToInitialFOV option to UCameraAnim, defaulting to true. If turned off, camera anims will use the camera's current FOV as the initial FOV for the animation

	#jira FORT-23606

Change 3010411 on 2016/06/12 by Bob.Tellez

	#UE4 Fix for a possible case where a reference to an async loading package that would contain a level gets replicated before the level it contains is fully serialized, causing network loading code client side to attempt to load the package even though it is not allowed to load maps.

	#jira FORT-113, FORT-22222

	#jira FORT-25361
	[FORT-25361] Health and shield values are incorrect when slotting survivors with bonuses
	- Fix some resultant bugs from swapping attributes to be struct-based:
	   - Fix issue wherein the initial creation of the client-side aggregator could be initialized with the computed final value from the server, resulting in incorrect client-side math
	   - Fix issue where subsequent changes to the aggregator's base value on the client would be lost

Change 3009514 on 2016/06/10 by Bob.Tellez

	#UE4 Remove final usage of the task graph in WmfMediaPlayer to dodge shutdown crashes.

Change 3009197 on 2016/06/10 by Michael.Trepka

Change 3008392 on 2016/06/09 by Ben.Zeigler

	#jira FORT-25244
	Change it so application error codes like 400/404 do not cause the mcp to think it is disconnected from the backend. Only 408, 501, 502, and 504 now result in ServiceUnavailable.

Change 3006633 on 2016/06/08 by Dmitry.Rekman

	Linux: propagate ensure message to the CR (FORT-23030).

	- Without this, ensure() has a generic "SIGTRAP" error message, which is misleading for QA.

	#tests Tried "debug ensure" a few times, observed crash report (on the website) with the proper message
	#jira FORT-23030

Change 3006036 on 2016/06/08 by Rob.Cannaday

	#jira FORT-18687

Change 3005216 on 2016/06/07 by Bob.Tellez

	#UE4 Avoiding layout invalidation if you use SetEnabled to set an identical enabled state. This is the same as how SetVisibility works.

	Increased the number of input buses for CoreAudio 3D Mixer to support 64 audio channels. Also, added a warning to FAudioDevice::StartSources so it doesn't silently ignore sound source initialization failures.

Change 3002048 on 2016/06/06 by Daniel.Broder

	Support for setting Scalar and Vector Materials by Index rather than by name on MIDs.

	This feature allows much better performance in cases where large numbers of parameters are being set per frame and where the indices can be cached by the calling code in an initialization step.

	#RB Stephan.Delmer

	#CodeReview Bob.Tellez

	#UE4 #ReleaseNote

Change 3001315 on 2016/06/05 by Daniel.Broder

	Fixed crash that could occur when the FPhysScene* was null (the world has no PhysicsScene) in USkeletalMeshComponent::TermArticulated().  That could happen when loading a world without fully instantiating it, such as when right-clicking a world in the context browser rather than opening the world directly.

	#RB Stephan.Delmer

	Ori, I wasn't sure if the whole line (and the line below it using PScene) should be moved within the if (PhysScene) block or not, but this change seems to fix it.  If they can safely be moved, that would be presumably more efficeint though (since we'd only compare vs. nullptr once).

	#CodeReview Ori.Cohen

	#UE4 #Fortnite #BugFix

Change 3001001 on 2016/06/04 by Fred.Kimberley

	Added meta data about attributes and a post serialize function so we can recover attributes that have changed their type.

	Adding Fortnite specific attribute type specialization. This type enforces minimum and maximum values for attributes.

Change 3000613 on 2016/06/03 by Sam.Spiro

	#fort online 24747

	#jira FORT-24422

Change 2997948 on 2016/06/02 by Eric.Newman

	Moved ProdCom to bottom of file w/ deprecation comment, and clarified deprecation criteria.  Will probably need to be removed in //UE4 first and check for any fallout from EC jobs failing

Change 2997660 on 2016/06/02 by Chris.Wood

	Changed Linux server crash handler to force CRC log paths to match main engine log.
	[UE-30259] - Some server crashes are missing from crashreporter database

Change 2991738 on 2016/05/26 by Bob.Tellez

	Manual merge of CL #2907874:
	When MCP cancels a request due to its required auth failing, the http retry system would never kick off the complete delegates.

	The fix is to add the request to the list when it is cancelled if we did not find it.

	#jira [FORT-6139]
	Trap models persist after destroying supporting structure in Outpost
	- Root issue was caused by error within network dormancy and queued bunches: If a dormant actor's open bunch ended up queued and a close bunch came in before the bunch was processed, the actor would never be properly destroyed client side as a result of not re-establishing the channel's actor pointer
	- Fix issue by changing close bunches to not be fully processed until their appropriate place in the queue. While this could cause superfluous execution (i.e. actor recreated just to be immediately destroyed), it should respect gameplay programming intent in regards to RPCs

Change 2911009 on 2016/03/15 by Bob.Tellez

	#UE4 Fixed a bug in UHierarchicalInstancedStaticMeshComponent where RemoveInstances would not rebuild the ClusterTree, causing SortedInstances to contain incorect indices in GetInstancesOverlappingBox.

	#orion - Lower default NetUpdateFrequency for minions (10->6). Avoid excessive latency for some knockback/knockup abilities that would have noticeable lag by forcing an update sooner when they are triggered.

	This should have the following effects:
	1. Reduce server CPU cost (we tick minions at the net frequency).
	2. Reduce server bandwidth
	3. Reduce client CPU cost (we move character capsules and perform overlaps when new positions are received).

Change 2946645 on 2016/04/18 by Richard.Fawcett

	When promoting a buidl to staged, prevent enumeration of files already in S3

	Enumerating files in S3 is a slow process, and it turns out that simply uploading all chunks blindly is more efficient than enumerating existing chunks and selectively uploading only the new ones.

	#rb Leigh.Swift
	#tests This technique has already been used in launcher promotions for several months

Change 2946622 on 2016/04/18 by Richard.Fawcett

	By default, when enumerating chunks from a manifest file, skip checking they exist on disk at enumeration time.

	This will fail anyway further down the line if the files don't exist, but will improve speed of stage promotions by around five minutes. In practice, we have NEVER seen a job fail at this point because of the existence check.

	#rb Leigh.Swift
	#tests Ensure that output of ExtractDataFilenamesFromManifest method is identical both with and without bSkipExistsCheck specified.

	Fix for OR-19778

	When some pooled systems are reused, on init they have a non zero lod level but the emitter instances are created at LOD 0 initially.
	So the component did not think it had to update it's LOD but the emitters were not at the correct LOD.
	Have forced a LOD set on init when the component LOD is non-zero.

Change 2943174 on 2016/04/13 by Aaron.McLeran

	OR-19392 Ensure condition failed: (*RequiresInitialization == 0) on loading into PVP match

	- Removing ensure since there is a rare edge case where it's possible for a sound looping node may get ResetChildren called twice.
	- Condition is when a child random node o fa looping node has a blank entry and results in no sound chosen in a given frame (which results in ResetChildren getting called). Later in the frame, if a sound had previously been playing with an active sound, it will have stop called on it, which will call NotifyWaveInstanceFinished and hit the ensure. Simply using the branch to check if the looping node has been initialized will work fine in this and other cases.
