c72b7a33d8 Merging //UE4/Dev-Rendering-Graph@4492585 to Dev-Rendering (//UE4/Dev-Rendering)
This implements the framework to write the high level rendering code into passes organized in direct acyclic graph. It is also unifying the uniform buffer, shader parameters, and pass parameters to same single API: structures with run time meta data. This allow high level user code be extremely seamless, user code debugging, and render graph ease of implementation and debugging.

Issue of collaborative work of Arne Schnober, Brian Karis, Daniel Wright, Marcus Wassmer and Guillaume Abadie.

Names of the graph managed resources are not final.

0cf4a7b4cd Merging from Dev-Niagara 4360525, 4360676, 4364096 for Simon.Tovey
Some compile time optimizations

- Moved large map of hlsl keyword replacements from C++ to ini file to improve compile times.
- Now not using templates to handle input parameters to data interface. Now taking a bit from the bytecode offset to denote constant vs register.
- As well as improving compile times, this also makes DIs far easier to write and maintain so I've rolled out to all DIs. Has no affect on perf.
- Moved some things into the VectorVM namesspace.

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

Change 4073167 by Krzysztof.Narkowicz

	Added subsurface profile for eye shading model.
	#jira none

Change 4073422 by Krzysztof.Narkowicz

	Added dual specular for subsurface profile shading model.
	#jira none

Change 4075278 by Krzysztof.Narkowicz

	Fixed forward reflection/refraction rendering issues, which caused ShaderModels.Material.Refraction to fail.
	#jira none

Change 4084231 by Krzysztof.Narkowicz

	Dual specular - replace lobe spread with two separate roughness multipliers. Default material roughness is now replaced by an average lobe roughness in order to support non dual specular features.
	#jira none

Change 4092798 by Matt.Collins

	Some HDR refactoring.

	Previously the DisplayOutput and ColorGamut were only set in GameUserSettings.
	I added a Sink that checks the HDR enable. If it's toggled we apply the correct DisplayOutput and ColorGamut for the current platform (this way we get good settings even if you toggle via the console). These settings are still exposed via the console and can be set independently if the user wants.

Change 4096954 by Chris.Bunner

	Added ShaderModelID as scene texture option and renamed existing value to ShaderModelColor to better reflect the internal code.

Change 4111285 by Brian.Karis

	Eye shading update.
	Added Iris normal (disabled). Removed wrap. Fixed contact shadows.

Change 4155261 by Krzysztof.Narkowicz

	Planar reflection prefilter - use scene viewport size instead of reflection target size in order to keep filter size constant in screen space. This makes planar reflection filter more stable in case of dynamic resolution.

	#jira none

Change 4167644 by Krzysztof.Narkowicz

	Global shader map is now stored in multiple DDC entries (one per shader filename) instead of keeping everything in a single one. This allows to skip recompilation of unchanged shader files.

Change 4183727 by Yuriy.ODonnell

	Implemented auto-conversion from deferred to DBuffer decals in forward shading mode (when GBuffer is not available).

	Added support for specular and metallic channels for DBuffer decals, based on work by Chris Bunner.
	This requires DBufferC to be expanded from 2 to 4 channels, leading to slight increase in DBuffer bandwidth and memory requirements.

	Appearance of DBuffer decals is affected by this change, as specular and metallic channel values previously hard-coded in DBufferDecalShared.ush.
	Decals were forced to be non-metallic and have specular of 4% (0.5 numeric value). Now the authored decal material values will be used, which matches GBuffer decals.

	Added support for DBuffer decals with emissive component.

	Most decal types can now be automatically converted, with the exception of stain decals. Those are currently approximated as regular translucent decals.

Change 4197684 by laz.matech

	Added a PostProcess Volume test to the map to test that Cinematic Depth of View can be achieved through PPVs as well. Changed the BP_DepthOfFeildPOV asset - I exposed Focus Method so that it can be disabled for the PPV test. Added a second Hair Model head to the InFocusHair test so that it tests in and out of focus hair models (changed the name of the test to FocusHair).

	#jira none

Change 4225614 by Rolando.Caloca

	DR - Enable depth collision particles on Vulkan mobile

Change 4235489 by Uriel.Doyon

	Removed r.DefaultFeature.PointLightUnits and r.DefaultFeature.SpotLightUnits and replaced them by a single r.DefaultFeature.LightUnits which also controls the units of newly placed rect lights.

	#jira UE-59525

Change 4260154 by Mark.Satterthwaite

	Parallelize the creation of Metal archives and libraries when they are broken up into smaller sub-libraries, this should reduce apparent cook time by going wide across threads on the host of the cooker.

Change 4270594 by Brian.Karis

	Fix for textured rect light L pointing away from plane due to approximate diffuse integration.

Change 4273361 by Daniel.Wright

	Particle Cutouts with 8 verts now always use stochastic approach.  Circle textures with > 234 edges in the convex hull were overflowing the uint64 calculation of the total number of combinations, causing an infinite loop.

Change 4309174 by Mark.Satterthwaite

	Graph device utilization from the driver monitor stats - really helps see how well the GPU is being used.

Change 4310121 by Matt.Collins

	Optmizing RemoveUniformBuffersFromSource. Brings it from ~20% to ~1.5% in my testing.

	#jira none

Change 4312960 by Daniel.Wright

	Fix from Stephen Hill for incorrect light grid culling near the near plane

Change 4314169 by Richard.Wallis

	FShaderCache and associated public structures are now marked as deprecated.  All FShaderCache code hooks removed from MetalRHI, OpenGLDrv and engine Launch/Shutdown logic.

	#jira none

Change 4320760 by Arne.Schober

	DR - Remove SV_Coverage from basepass interpolants when running with Masked in early Depth with ForwardShading as otherwise earlyZ will be disabled (as the PS has to run).
	#jira UE-60992

Change 4334607 by Uriel.Doyon

	Added custom overrides to reset ULightComponent::Intensity to default (in FLightComponentDetails).
	Now settings a light Intesity to default resets the brightness to the archetype brightness.
	This handles correctly cases where the intensity units differs between the two objects.
	Also changed FLocalLightComponentDetails so that changing intensity units kepts the same brightness
	(by recomputing the Intensity).

	#jira UE-61401

Change 4336188 by Rolando.Caloca

	DR - Added -ReduceThreadUsage so programs can use less threads (for SCW )

Change 4337967 by Rolando.Caloca

	DR - Remove unused RHISupportsShaderCompression function

cdbff82b3d Skeletal mesh improvements / additions
? Adding object version header for Dev-Niagara stream. Used to modify skeletal mesh data.
? Modified DataInterface outputs to be optional using a change to the register handler so it writes to a dummy value when the value is optonal.
? Refactored API so a single function can now output Position, Velocity and NBT data in any combination.
? Adding compile error and info when a DI function does not match a calling node. Allows DI APIs to be reworked safely. Though you do need to trigger a recompile when any API is changed.
? Refactored Triangle sampling functions to own cpp
? Vertex Sampling functions in own cpp
? Bone + Socket sampling functions in own cpp. (Experimental skeleton sampling in another shelf, left out of code for now)
? Made SkinOnTheFly the default for skinning mode.

	+ 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.

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

Change 3879958 by Frank.Fella

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

	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

	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.

	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.

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.

	New helper functions returning the min index, max index and number of particles to be spawned for a given time value.
	Uses an internal LastSpawnIndex to avoid spawning the same particles twice.
	- Modified GetLastParticleIndexAtTime():
	If the CSV file doesn't have time informations, returns false and set the LastIndex to the last particle
	If desiredTime is smaller than the first particle, LastIndex will be set to -1
	If desiredTime is higher than the last particle in the csv file, LastIndex will be set to the last particle's index

	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.

Change 4050566 by Olaf.Piesche

	-More fixes and changes for async gpu buffer readback
	-removed more CPU intervention; spawning and death now happen largely without CPU direction, other than determining the number of particles to spawn
	-Added piping number of vert indices per instance from the renderer down to the GPU context and CS; as a result, GPU simulated mesh emitters are working again; this will need a bit of additional work to handle multiple renderers (will need multiple DrawIndirect parameter buffers reflecting the different renderers)
	-General cleanup and prettification

	We can't rely on properties in the emitter being loaded before the call to UNiagaraScript::PostLoad() so this is unsafe.

	#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

Change 3941865 by Mark.Satterthwaite

	Fix the incorrect landscape rendering and the incorrect render-to-texture from blueprint bugs with MetalRHI.

	- Track outstanding AsyncCopyBufferFromBufferToBuffer operations to identify attempts to modify overlapping ranges within the same prologue command-buffer. This doesn't work and requires that we break the current render-pass and issue on the current command-buffer. A log warning will be emitted  when this occurs.

	- Don't attempt to alias private memory buffers the moment they are released from the RHI resource because that can lead to incorrect sharing of the memory when used by AsyncCopyBufferFromBufferToBuffer.

	#jira UE-56021

Change 3940993 by Marc.Audy

	Do not return the last column if the specified column does not exist.

Change 3938305 by Mark.Satterthwaite

	For whatever reason moving the buffer initialisation into the prologue command buffer doesn't work - this make absolutely no sense to me. I suspect that this is *merely* moving a render pass boundary around somewhere and forcing raster-state to be reapplied.

Change 3934892 by Mark.Satterthwaite

	In MetalRHI treat BUF_Volatile buffers as Shared or Managed memory in all circumstances so that multiple updates within a render pass are respected even though this will hurt CPU performance. This fixes GPU particles on macOS. Also push initialisation upload into the async. command buffer to avoid it overwriting a later Lock/Unlock! Only read-back and copy-buffer operations should be on the 'current' command buffer as they need to be inline with all outstanding commands.

Change 3920519 by Phillip.Kavan

	Fix a regression in which elements would not be initialized when constructing the value assignment for UDS-typed container members in nativized Blueprint C++ code.

	Change summary:
	- Modified FEmitDefaultValueHelper::InnerGenerate() to remove UDS from the list of special cases that avoid calling InitializeStruct() as part of new element construction. Previously the conversion code assumed the compiler would perform value initialization of a nameless temporary, but that is no longer valid in 4.19, as UDS types have been changed to function more like native structs, and as such all converted UDS types will now emit an explicit default ctor which is now used to assign defaults that differ from the zero-initialized value.

Change 3920004 by Jack.Porter

	Disable Manual Vertex Fetch SRV creation when MVF is disabled.

	Made a single RHISupportsManualVertexFetch(EShaderPlatform) to control whether to use MVF. The Shader Platform (or alternatively, feature level) is the only thing that can decide whether or not to use MVF because we need to know when we compile the shaders if we're going to do MVF or not. Checking GSupportsResourceView at runtime is useless because the shaders can't change and so if GSupportsResourceView can ever be false for a platform, the shaders need to have been built without it.

	Creating SRVs without using them on mobile is not harmless because several devices don't support formats that are needed.

	Place buffer updates into the prologue command-buffer in MetalRHI to avoid breaking the current command-encoder. This improves performance, though the semantics of Metal now differ subtly to other RHI implementations as the buffer updates happen prior to the SetRenderTargets call in the GPU's view of the world.

	#jira UE-55592

Change 3915250 by JeanLuc.Corenthin

	Can't add C++ code to Enterprise projects (when enterprise is installed)

	Root cause: When compiling a C++ project, Datasmith modules are included in the build process (with the wrong path)

	Fix:
	- Added two more Enterprise directories, Plugins and Intermediate, to the Enterprise directories to check against
	- Build the correct path for the Datasmith modules and plugins in FindOrCreateModuleByName. Added check to see if module is under one of the Enterprise directories.
	- Added modules to list of precompiled modeules in UEBuildTargets.AddPrecompiledModules if Engine and Enterprise are 'installed and the module is under Enterprise.

	#jira UEENT-1032

Change 3915240 by Ben.Marsh

	Reduce editor startup times by ~15s on Windows.

	Platform loading code recursively scans every module for dependent DLL modules to load first. Change to make it early-out as soon as it encounters a module which is already in memory (via a call to GetModuleHandle() from ResolveMissingLibraryImportsRecursive). Also use a TSet<> to store set of visited modules rather than an Array.

	Now spends <0.1s total in this function on editor startup.

	(Change looks larger than it is due to moving functions out of WindowsPlatformProcess.h to avoid introducing TSet dependency into this header).

	Adding Calibrate button #jira none

Change 3914599 by Andrew.Rodham

	Sequencer: Sequence template source signatures are now also compared to catch the case where a sub-sequence asset has been saved but not modified

	  - The following sequence of events exposes this issue:
	    - Create a master sequence with a single shot that spawns a cube
	    - Add this sequence to a level and set it to auto-play
	    - Save everything and restart
	    - Resave just the inner shot asset without opening it
	    - PIE
	    - The inner shot never spawns its cube because its template was wiped on save, but its signature never changed. Since the master sequence previously didn't check the template source signature, it ends up trying to evaluate an empty template.

	Change summary:
	- Modified FEmitDefaultValueHelper::HandleSpecialTypes() to skip editor-only checks for instanced default subobjects. These will have already been created by a native parent class.
	- Modified FEmitDefaultValueHelper::HandleInstancedSubobject() to assert before creating a "dummy" component in place of an editor-only instance if we're not supposed to be creating it.

	 - Fix replaces the TArray with a TStaticArray of max size MAX_SUBSECTION_COUNT (which is 4).

	#jira UE-55394
	#jira UE-52328
	#iOS
	#4.19

	This is a particular case of UE-52328 iOS reporting crash on application exit: SPRINGBOARD, process-exit watchdog transgression

	Found several issues on iOS if the game is forced closed when the startup movie is playing and "Wait for movies to complete" is enabled in Project Settings

	- the game thread is waiting for the movie to complete on game shutdown - more that 5 sec

	- crash on FDefaultGameMoviePlayer::Shutdown if the above is fixed

	- HTTP module no longer has time to wait for the requests to complete.

	- as for fullbody, went back to old mathod because in the fullbody, we want shortest path most of times and you don't blend more than 1 weight, so this is likely fine
	- as for additive, change to use blend from identity.

	[CONSOLE] [^] Added RHI Command List Enqueue Lambda method (merging as edit CL 3879722 from //Fortnite/Main to //UE4/Release-4.19)

	 - Can be used to enqueue arbitrary tasks on the RHI thread from the render thread (similar to how EURC works for GT -> RT tasks), without having to write lots of bolierplate FRHICommand functor classes.
	 - The first overload of EnqueueLambda method will check Bypass() to determine if it should run the lambda immediately or defer to the RHI thread.
	 - This can be overriden via the 2nd overload if you need to check additional things such as IsRunningRHIInSeparateThread.
	 - The function returns true if the lambda was enqueued and deferred to the RHI thread, otherwise false. This can be used to optionally add RHIThreadFences for unlock commands etc.

	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).

	Sequencer: Fixed overlapping ranges being inserted into the evaluation field during compilation

	  - The issue was that track segments that had been combined with adjacent segments (due to them being identical) would potentially cause a subsequently compiled frame to overlap with a range that had already been inserted into the evaluation field.
	  - The insertion code previously asserted that only minor overlaps were catered for (due to fp rounding errors) and assumed that a supplied range could not entirely contain any other range in the field.
	  - The solution is to supply the insertion time along with the range to know exactly where the data should live in the field, and crop the range to the maximum allowable space between adjacent ranges.

	#jira UE-54272

Change 3877545 by Ben.Marsh

	Replace FPlatformMisc::DebugBreak() with the UE_DEBUG_BREAK() macro. VS2017 is able to show force-inlined calls on the callstack, which makes debugging asserts and ensures annoying.

	Use similar logic for expanding ensure() macros in place.

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

Change 3805828 by Gil.Gribb

	UE4 - Fixed a bug in the lock free stalling task queue and adjusted a comment. The code is not current used, so this is not actually change the way the code works.

Change 3806784 by Ben.Marsh

	UAT: Remove code to compile UBT when using UE4Build. It should already be compiled as a dependency of UAT.

Change 3807549 by Graeme.Thornton

	Add a cook timer around VerifyCanCookPackage. A licensee reports this taking a lot of time so it'll be good to account for it.

Change 3807727 by Graeme.Thornton

	Unhide the text asset format experimental editor option

Change 3807746 by Josh.Engebretson

	Remove WER from iOS platform

Change 3807928 by Robert.Manuszewski

	When async loading, GC Clusters will be created after packages have been processed to avoid situations where some of the objects that are being added to a cluster haven't been fully loaded yet

Change 3808221 by Steve.Robb

	GitHub #4307 - Made GetModulePtr() thread safe by not using GetModule()

	^ I'm not convinced by how much thread-safer this is really, but it's tidier anyway.

Change 3809233 by Graeme.Thornton

	TBA: Misc changes to text asset commandlet
	 - Rename mode to "loadsave"
	 - Add -outputFormat option which can be assigned "text" or "binary"
	 - When saving binary, use a differentiated filename so that source assets aren't overwritten

Change 3809518 by Ben.Marsh

	Remove the outdated UnrealSync automation script.

Change 3809643 by Steve.Robb

	Incorrect semi-colon search removed after discussion with author.
	Test added.

	#jira UE-48242

Change 3812864 by Steve.Robb

	Removal of some unproven code which was supposed to fix hot reloading BP class functions in plugins.

	See: https://udn.unrealengine.com/questions/376978/aitask-blueprint-nodes-disappear-when-their-module.html

	#jira UE-53089

Change 3820358 by Ben.Marsh

	PR #4358: Incredibuild use ShowAgent by default (Contributed by projectgheist)


Change 3822594 by Ben.Marsh

	UAT: Improvements to log file handling.

	- Always create log files in the final location, rather than writing to a temp directory and copying in later.
	- Now supports -Verbose and -VeryVerbose for increasing log verbosity, rather than -Verbose=XXX.
	- Keep a backlog of log output before the log system is initialized, and flush it to the log file once it is.
	- Allow buildmachines to specify the uebp_FinalLogFolder environment variable, which is used to form paths for display. When build machines copy log files elsewhere after UAT finishes (eg. a network share), this allows error messages to display the right location.

Change 3823695 by Ben.Marsh

	UGS: Fix issue where precompiled binaries would not be shown as available for a change until scrolling the last submitted code change into the buffer (other symptoms, like de-focussing the main window would cause it to go back to an unavailable state, since the changes buffer was shrunk).

	Now always queries changes up to the last change for which zipped binaries are available.

Change 3823845 by Ben.Marsh

	UBT: Exclude C# projects for unsupported platforms when generating project files.

Change 3824180 by Ben.Marsh

	UGS: Add an option to show changes by build machines, and move the "only show reviewed" option in there too (Options > Show Changes).

	#jira

Change 3825777 by Steve.Robb

	Fix to return value of StringToBytes.

Change 3825810 by Ben.Marsh

	UBT: Reduce length of include paths for MSVC toolchain.

Change 3825822 by Robert.Manuszewski

	Optimized PIE lazy pointer fixup. Should be up to 8x faster now.

Change 3826734 by Ben.Marsh

	Remove code to disable TextureFormatAndroid on Linux. It seems to be an editor dependency.

Change 3827730 by Steve.Robb

	Try to avoid decltype(auto) if it's not supported.

	See: https://udn.unrealengine.com/questions/395644/build-417-with-c11-on-linux-ttuple-errors.html

Change 3827745 by Steve.Robb

	Initializer list support for TMap.

Change 3827770 by Steve.Robb

	GitHub #4399 : Added a CONSTEXPR qualifiers to FVariant::GetType()

	#jira UE-53813

Change 3829189 by Ben.Marsh

	UBT: Now always writes a minimal log file. By default, just contains the regular console output and any reasons why actions are outdated and needed to be executed. UAT directs child UBT instances to output logs into its own log folder, so that build machines can save them off.

Change 3830444 by Steve.Robb

	BuildVersion and ModuleManifest moved to Core, and parsing of these files reimplemented to avoid a JSON library.
	This should be revisited when Core has its own JSON library.

Change 3830718 by Ben.Marsh

	Fix incorrect group name being returned by FStatNameAndInfo::GetGroupName() for stat groups.

	The editor populates the viewport stats list by calling this for every registered stat and stat group (via FLevelViewportCommands::HandleNewStatGroup). The menu entry attempts to show the stat name with STAT_XXX stripped from the start as the menu item label, with the free-form text description as a tooltip.

	For stat groups, the it would previously just return the stat group name as "Groups" (due to the raw naming convention of "//Groups//STATGROUP_Foo//..."). Since this didn't match the expected naming convention in FLevelViewportCommands::HandleNewStat (ie. STAT_XXX or STATGROUP_XXX), it would fail to add it.

	When the first actual stat belonging to that group is added, it would add a menu entry for the group based on that, but the stat description no longer makes sense as a tooltip for the group. As a result, all the editor tooltips were junk.

	#jira UE-53845

Change 3831064 by Ben.Marsh

	Fix log file contention when spawning UBT recursively.

Change 3832654 by Ben.Marsh

	UGS: Fix error panel not being selected when opened, and weird alignment/color issues on it.

Change 3832680 by Ben.Marsh

	UGS: Fix failing to detect workspace if synced to a different stream. Seems to be a regression caused by recent P4D upgrade.

Change 3832695 by Ben.Marsh

	UGS: Invert the options in the 'Show Changes' submenu for simplicity.

Change 3833528 by Ben.Marsh

	UAT: Script to rewrite source files with public include paths relative to the 'Public' folder. Usage is: RebasePublicIncludePaths -UpdateDir=<Dir> [-Project=<Dir>] [-Write].

Change 3833543 by Ben.Marsh

	UBT: Allow targets to opt-out of having public include paths added for every dependent module. This reduces the command line length when building a target, which has recently become a problem with larger games (due to Microsoft's compiler embedding the command line into each object file, with a maximum length of 64kb). All engine modules are compiled with this enabled; games may opt into it by setting bLegacyPublicIncludePaths = false; from their .target.cs, as may individual modules.

Change 3834354 by Robert.Manuszewski

	Archetype pointer will now be cached to avoid locking the object tables when acquiring its info. It should also be faster this way regardless of any locks.

	#jira UE-52035

Change 3834400 by Robert.Manuszewski

	Fixing crash on exit caused by cached archetypes not being cleaned up before static exit cleanup.

	#jira UE-52035

Change 3834947 by Steve.Robb

	USE_FORMAT_STRING_TYPE_CHECKING removed from FMsg::Logf and FMsg::Logf_Internal.

Change 3835004 by Ben.Marsh

	Fix code that relies on dubious behavior of requiring referenced "include path only" modules having their _API macros set to be empty, even if the module is actually implemented in a separate DLL.

Change 3835340 by Ben.Marsh

	Fix errors making installed build from directories with spaces in the name.

Change 3835972 by Ben.Marsh

	UBT: Improved diagnostic message for targets which don't need a version file.

Change 3836019 by Ben.Marsh

	UBT: Fix warnings caused by defining linkage macros for third party libraries.

Change 3836269 by Ben.Marsh

	Fix message box larger than the screen height being created when a large number of modules are incompatible on startup.

Change 3836543 by Ben.Marsh

	Enable SoundMod plugin on Linux, since it's already supported through the editor.

Change 3836546 by Ben.Marsh

	PR #4412: fix type mismatch (Contributed by nakapon)


Change 3836805 by Ben.Marsh

	Fix commandlet to compile marketplace plugins.

Change 3836829 by Ben.Marsh

	UBT: Fix ability to precompile plugins from installed engine builds.

Change 3837036 by Ben.Marsh

	UBT: Write the previous and new contents of intermediate files to the log if they change. Makes it easier to debug unexpected rebuilds.

Change 3837037 by Ben.Marsh

	UBT: Fix engine modules having inconsistent definitions depending on whether modules are only referenced for their include paths vs being linked into a binary (due to different _API macro).

Change 3837040 by Ben.Marsh

	UBT: Remove code that initializes members in ModuleRules and TargetRules objects before the constructor is run. This is no longer necessary, now that the backwards-compatible default constructors have been removed.

Change 3837247 by Ben.Marsh

	UBT: Remove UELinkerFixups module, now that plugins and precompiled modules do not require hacks to force initialization (since they're linked in as object files).

	Encryption and signing keys are now set via macros expanded from the IMPLEMENT_PRIMARY_GAME_MODULE macro, via project-specific macros added in the TargetRules constructor.

Change 3837262 by Ben.Marsh

	UBT: Set whether a module is an engine module or not via a default value for the rules assembly. All non-program engine and enterprise modules are created with this flag set to true; program targets and modules are now created from a different assembly that sets it to false. This removes hacks from UEBuildModule needed to adjust behavior for different module types based on the directory containing the module.

	Also add a bUseBackwardsCompatibleDefaults flag to the TargetRules class, also initialized to a default value from a setting passed to the RulesAssembly constructor. This controls whether modules created for the target should be configured to allow breaking changes to default settings, and is set to false for all engine targets, and true for all project targets.

Change 3837343 by Ben.Marsh

	UBT: Remove the OverrideExecutableFileExtension target property. Change the only current use for this (the MayaLiveLinkPlugin target) to use a post build step to copy the file instead.

Change 3837356 by Ben.Marsh

	Fix invalid character encodings.

Change 3837727 by Graeme.Thornton

	UnrealPak: KeyGenerator: Only generate prime table when required, not all the time

Change 3837823 by Ben.Marsh

	UBT: Output warnings and errors when compiling module rules assembly in a way that allows them to be double-clicked in the Visual Studio output window.

Change 3837831 by Graeme.Thornton

	UBT: When parsing crypto settings, always load legacy data first, then allow the new system to override it. Provides the same key backwards compatibility that the editor settings class gives

Change 3837857 by Robert.Manuszewski

	PR #4404: Make FGCArrayPool singleton global instead of per-CU (Contributed by mhutch)


Change 3837943 by Robert.Manuszewski

	PR #4405: Fix FGarbageCollectionTracer (Contributed by mhutch)


Change 3838451 by Ben.Marsh

	UBT: Fix exceptions thrown on a background thread while caching C++ includes not being caught and logged correctly. Now captures exceptions and re-throws on the main thread.

	#jira UE-53996

Change 3839519 by Ben.Marsh

	UBT: Simplify configuring bPrecompile and bUsePrecompile settings for modules. Each rules assembly can now be configured as installed, which defaults the module rules it creates to use precompiled data.

Change 3843790 by Graeme.Thornton

	UnrealPak: Log the size of all encrypted data

Change 3844258 by Ben.Marsh

	Fix plugin compile failure when created via new plugin wizard. Passing -plugin on the command line is unnecessary, and is now reserved for packaging external plugins for the marketplace.

	Also extend the length of time that the error toast stays visible, and don't delete the plugin on failure.

	#jira UE-54157

Change 3845796 by Ben.Marsh

	Workaround for slow performance of String.EndsWith() on Mono.

Change 3845823 by Ben.Marsh

	Fix case sensitive matching of platform names in -TargetPlatform=X argument to BuildCookRun.

	#jira UE-54123

Change 3845901 by Arciel.Rekman

	Linux: fix crash due to lambda lifetime issues (UE-54040).

	- The lambda goes out of scope in FBufferVisualizationMenuCommands::CreateVisualizationCommands, crashing the editor if compiled with a recent clang (5.0+).

	(Edigrating 3819174 to Dev-Core)

Change 3846439 by Ben.Marsh

	Revert CL 3822742 to always call Process.WaitForExit(). The Android target platform module in the editor spawns ADB.EXE, which inherits the editor's stdout/stderr handles and forks itself. Process.WaitForExit() waits for EOF on those pipes, which never occurs because the forked process never terminates.

	Proper fix is probably to have the engine explicitly duplicate stdout/stderr handles for new pipes to output process, but too risky before copying up to Main.

Change 3816608 by Ben.Marsh

	UBT: Use DirectoryReference objects for all include paths.

Change 3816954 by Ben.Marsh

	UBT: Remove bIncludeDependentLibrariesInLibrary option. This is not widely supported by platform toolchains, and is not used anywhere.

Change 3816986 by Ben.Marsh

	UBT: Remove UEBuildBinaryConfig; UEBuildBinary objects are now just created directly.

Change 3816991 by Ben.Marsh

	UBT: Deprecate PlatformSpecificDynamicallyLoadedModules. We no longer have any special behavior for these modules.

Change 3823090 by Ben.Marsh

	UAT: Improve logging for child UAT instances.

	- Calling RunUAT now requires an identifier for prefixing into the parent log, which is also used to determine the name of the log folder.
	- Stdout is no longer written to its own output file, since it's written to the parent stdout, the parent log file, and the child log file anyway.
	- Log folders for child UAT instances are left intact, rather than being copied to the parent folder. The derived names for the copied names were confusing and hard to read.
	- Output from UAT is no longer returned as a string. It should not be parsed anyway (but may be huge!). ProcessResult now supports running without capturing output.

Change 3826082 by Ben.Marsh

	UBT: Add a check to make sure that all modules that are precompiled are correctly marked to enable it, even if they are part of the build target.

Change 3827025 by Ben.Marsh

	UBT: Move the compile output directory into a property on the module, and explicitly pass it to the toolchain when compiling.

Change 3829927 by James.Hopkin

	Made HTTP interface const correct

Change 3833533 by Ben.Marsh

	Rewrite engine source files to base include paths relative to the "Public" directory. This allows reducing the number of public include paths that have to be added for engine modules.

Change 3835826 by Ben.Marsh

	UBT: Precompiled targets now generate a separate manifest for each precompiled module, rather than adding object files to a library. This fixes issues where object files from static libraries would not be linked into a target if a symbol in them was not referenced.

Change 3835969 by Ben.Marsh

	UBT: Fix cases where text is being written directly to the console rather than via logging functions.

Change 3837777 by Steve.Robb

	Format string type checking added to FOutputDevice::Logf.
	Fixes for those.

Change 3838569 by Steve.Robb

	Algo moved up a folder.
