  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

============================

Change 3774677 by Arne.Schober

	DR - Deprecated SetLocal from the RHICmdlist
	Fixed some unnecessary PSO collisions.

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.

Change 3844946 by Mark.Satterthwaite

	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.

	DR - Fix OpenGL overwriting texture samplers on forward renderer

Change 3853945 by Mark.Satterthwaite

	Duplicate #3831616

	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 3853966 by Mark.Satterthwaite

	Duplicate #3835852

	Fix tessellation shaders in Metal with Manual Vertex Fetch enabled:
	- The control points idnex buffer shouldn't collide with anything else.
	- We can't use the optimisation of loading texture width & height from the buffer meta-table in tessellation shaders as the combined stages don't guarantee not to clobber unused buffer slots and screw it up when we use linear textures.

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

	Fixed padding in nested uniform buffer structs
	Skip SRV members on Feature Level SM4 and below

	DR - vk - Renderdoc on Android

Change 3933095 by Daniel.Wright

	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.

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.

	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.

	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.

	Previously, if your map needed to UpdateSkyCaptureContents on startup, an ensure would fail if GWaitForIdleOnSubmit was set.
	PrepareForCPURead needs to wait for the command buffer to finish before trying to read the results back, but the wait has already happened when r.Vulkan.WaitForIdleOnSubmit is set. Trying to wait again correctly complains that the command buffer is not in the correct state. So, skip the WaitForCmdBuffer call when r.Vulkan.WaitForIdleOnSubmit is set.

Change 4007682 by Richard.Wallis

	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.
	- Renamed a variable in the AvfMediaVideoSample - was called FrameRate but it was the FrameDuration by that point.

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.

	#jira UE-58267

Change 3810277 by Daniel.Wright

	Ray Traced Distance Field shadows use a two pass tile culling algorithm with no tile max - fixes flickering from tile overflow in dense areas or with a low sun angle.  Costs .2ms on PS4.
	The distance field scene buffers now use float4 on PS4 and Xbox, saves .1ms on PS4.

Change 3817029 by Uriel.Doyon

	Added UVolumeTexture, which use 3D textures. Compressed formats are supported on DX11, DX12, PS4 and XB1.
	Projects targetting OpengGL don't have access to compressed formats (as the implementation has texture tiling issues).
	Add "r.AllowVolumeTextureAssetCreation" set as 0 by default, which controls whether volume texture can be sampled in materials and whether they can be created from 2D texture assets.
	Platform not supporting BC7, will now fallback on RGBA8 instead of DXT to preserve quality, in an attemps to increase usage of BC7.

	#jira UE-32263

Change 3819960 by Michael.Lentine

	Expose UEPhysics Clothing Parameters through UI.

Change 3823401 by Rolando.Caloca

	DR - Add NumQueriesInBatch to RHIBeginOcclusionQueryBatch

Change 3844805 by Arne.Schober

	DR - Increased Intermediate normal of Umodel and Skelmesh from 8bit Unorm Compressed to float. A resave/rebuid/reimport of the meshes is recommended to recover some lost precision.
	Fixed an issue with compressed (packed) normals on the GPU which were off by one integer representation. Also switched from UNORM to SNORM to get a discrete zero representation and removed some mads from all the VertexShaders.

Change 3876607 by Rolando.Caloca

	DR - Use render passes when running occlusion queries
	- Removes the RHI(Begin|End)OcclusionQueryBatch API

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 3917500 by Rolando.Caloca

	DR - Change depth bounds so only the enable bit is in the PSO, allow min/max to be dynamically modified

Change 3964907 by Guillaume.Abadie

	Implements RectList topology support in RHI.

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.

	- SetRate() should not required to be passed to media tracks - should be enough to do this on audio track select only.

	Data can be encoded inside the glTF JSON as a Base64 data URI. This CL addresses a known limitation of initial commit CL 3793018. I added this after because base64 is expected to be uncommon in the wild. Authoring software will typically use external BIN files (.gltf) or a BIN chunk (.glb) to store data.

	LLM update: Added Total, Untracked and FMalloc Unused to LLMFULL stat page. Fixed occasionally missing allocs/frees. Removed platform csv.

	* removed CheckSize arg from OnLowLevelFree
	* show a warning in LLM Map when replacing existing value. This means that there has been an alloc/free mismatch.
	* minor optimization in LLMMap::GetMaxIndex - cache Mask value
	* added Total and Untracked stats to LLMFULL. LLMFULL now tracks almost all of the memory that LLMPlatform does, so there is no real need to use LLMPlatform. Removed the LLMPlatform csv.
	* added FMalloc Unused stat to LLMFULL to account for memory Binned2 has allocated internally. This can be used to track Binned2 fragmentation over time.
	* renamed Binned stats to FMemory to make it more general
	* added Default tracking to CustomVirtualAlloc and disable it where necessary. This catches the few VirtualAlloc calls that were missed.
	* added AllocType arg to all allocation tracking. This was needed in order to track the FMalloc total, and also to fix the pausing
	* fixed a bug in pausing where alloc/frees were being missed. Now only pauses a specific allocation type.
	* Trackers now maintain totals for each enum tag
	* tracking of Texture and mesh allocation on Windows D3D11 & D3D12

	Merging CL 3659069 from //Fortnite/Main/... to to //ue4/dev-console/...:

	[FORTNITE] [CONSOLE] [+] Improved frame syncing mechanism
	 - Improves input latency by allowing the game thread to sync to the swap chain flip of the previous frame.
	 - Added "r.GTSyncType" CVar to control how the game thread syncs with the rest of the pipe.
	 - r.GTSyncType 2 will sync the game thread with the flip of the swap chain, preventing the pipe from getting too long and causing excess input latency.

	Platforms are required to implement RHIWaitForFlip and RHISignalFlipEvent, and call RHIInitializeFlipTracking on RHI startup.
	A separate thread monitors the progress of frame flips and signals task graph events as they pass their corresponding frame index.
	In r.GTSyncType 2 mode, the game thread is signaled by this flip tracking thread.

	[~] Unified platform specific sync interval CVars into one: rhi.SyncInterval
	 - 1 == 60Hz
	 - 2 == 30Hz
	 - 3 == 20Hz

	[CONSOLE] [+] Improved Scoped Named Events
	 - Added SCOPED_NAMED_EVENT(_FSTRING/_TEXT/_F) macros to allow use of string literals, FString and printf in scoped named event strings.
	 - Replaced explicit use of FPlatformMisc::Begin/EndNamedEvent throughout the engine with macros, so the events can be compiled out.

	- add support for pre-declared CSV stats, using FNames (these are required for GPU stats)
	- add DECLARE_GPU_STAT macro which handles STATS and CsvProfiler declarations
	Note: still a few issues to resolve with GPU stats: these randomly go to 0 at times during a replay on XB1, the GPU total is lower than the stat unit number, and the unaccounted stat is too large due to missing stats

Change 3813513 by Ben.Woodhouse

	CSV profiler refactor+ bug fix
	- Move the CSV profiler to core, so we can use it in modules other than engine
	- Profiler no longer enqueues RT commands - this is handled by a new core delegate type
	- Make begin/end requests more robust, enqueued via a command queue and processed in order
	- Defer end capture requests by a frame. This ensures stats on threads other than the gamethread (e.g. renderthread etc) are complete, so the last frame is not truncated
	- Fix long-standing bug with multiple captures where old/stale frames would appear in the first <128 frames of captures
	- Move unit stats and dynamic resolution out of the profiler itself and into the engine. Only frametime is recorded in the profiler now
	- Fix longstanding bug in first frame renderthread time in the engine

Change 3814039 by Ben.Woodhouse

	More Csvprofiler improvements
	- Event support (via CSV_EVENT macros). These appear in the "EVENTS" column of the CSV and can be used to add context to the stat data
	- Reduced memory overhead for timestamps through bit-packing (now 16 bytes per marker instead of 24), and splitting stats into different types

Change 3814041 by Ben.Woodhouse

	Integrate as edit CL 3796390 from Fortnite/Main:

	Fix CsvProfiler not compiling in shipping for now

Change 3814229 by Ben.Woodhouse

	Integrate + refactor of CL 3792591 to reduce complexity and fix bugs

	Original changelist description:
	CSV profiler improvements:
	- The CSV profiler is now always compiled in on the server
	- The CSV profiler can now handle both int32 and float stats
	- In BeginCapture, the function can take additional arguments for some customization of filenames

	Fixes to the above:
	 - Remove FCustomValue class
		- Fixes bug where all timestamp values from CSV_SCOPED_STATs were garbage (due to issues resulting from FCustomValue type ambiguity when adding values together)
		- FCsvCustomStat now just uses simple union + bitfield flag to reduce size and complexity (4 bytes instead of 8 per value)
		- FCsvColumn class modified to use doubles, which can represent both ints and floats without loss of precision - this class is not memory or time critical
	 - Replace multiple overrides used by the server for filenameprefix/folder/postfix etc with a single FilenameOverride

Change 3814242 by Ben.Woodhouse

	Disable CSV unit stats on the dedicated server

Change 3817339 by Ben.Woodhouse

	Duplicate from 3816641: CSV profiler improvements
	- Added a low-pri processing thread to compress raw timing data into a much more efficient format
	   - Reduces memory usage for 15 minute 30k frame capture with GPU stats enabled from 110MB to 3.4MB
	   - Processing time : 0.1ms per frame
	- Improved name handling for char literal stats. We now use the string as the ID rather than the pointer so multiple stat uses of the same name string apply only to  a single stat
	- Reworked thread data access to eliminate locking for anything time-critical. Frame boundaries now handled via a lock-free helper class
	-  Fixed bug with queue implementation where 1 in 128 reads would duplicate the last block of stat data
	-  Reduced #include dependencies for CSVProfiler.h
	-  Removed AccumulateMax because it doesn't work, and implementing properly would add a lot of complexity
	-  Added a simple test harness

Change 3817582 by Ben.Woodhouse

	Fix android compile warning

Change 3823242 by Ben.Woodhouse

	Integrate as edit from Fortnite/Main 3820067:

	Fix threading issue with D3D12 pipeline state caches for windows. This was caused by the usage of FRwScopeLock::RaiseLockToWrite. A pointer read before RaiseLockToWrite was called was invalidated because RaiseLockToWrite has to release the read lock before acquiring the write lock.

	Rename FRwScopeLock::RaiseLockToWrite to ReleaseReadOnlyLockAndAcquireWriteLock_USE_WITH_CAUTION to make it more explicit what's happening. As the comment says:

		// This function should be used with caution.
		// It releases the read lock _before_ acquiring a new write lock. This is not an atomic operation and the caller should
		// not treat it as such.
		// E.g. Pointers read from protected data structures prior to this call may be invalid after the function is called.

Change 3823840 by Ben.Woodhouse

	Edigrate from 3823816
	Fix an issue where the csvprofile console commands would sometimes result in an empty CSV. The root cause was GFrameNumber incrementing between the console command being read and FCSVProfiler::EndFrame(). We now use our own frame counter which is updated in EndFrame, so this can't happen

	Also fix an issue where calling csvprofile stop twice would cause all further commands to be ignored.

	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.

	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

	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 3587864 by Mark.Satterthwaite

	Fix the GPU hang on iOS caused by changes to the Depth-Stencil MSAA handling: you can't store the MSAA stencil results on iOS < 10 unless you use the slower MTLStoreActionStoreAndMultisampleResolve which we don't need for the mobile renderer.
	#jira UE-48342

Change 3587866 by Mark.Satterthwaite

	Correctly fix iOS compilation errors against Xcode 9 Beta 5 and Xcode 8.3.3 - duplicating function definitions is guaranteed to be wrong.

Change 3588168 by Mark.Satterthwaite

	Move the Xcode version into the Metal shader format header, not the DDC key, so that we can handle bad compiler/driver combinations in the runtime and don't force all users to recompile every time the Xcode version changes.

Change 3590905 by Mark.Satterthwaite

	For Metal shader compilation where the bytecode compiler is unavailable force the debug compiler flag and disable the archiving flag because storing text requires this.

	#jira UE-48163

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.

	#jira UE-46688, UE-39256, UE-47215

	Enable the new GRHIRequiresRenderTargetForPixelShaderUAVs flag as Metal is like Vulkan and needs a target for fragment rendering.
	Also fix the filename for direct-compile & remove the old batch file generation in the Metal shader compiler.

Change 3606009 by Mark.Satterthwaite

	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....

	#jira UE-46004

Change 3490228 by Mark.Satterthwaite

	Fix the Nvidia driver bug with the old reversebits fallback function - you need to use the native reverse_bits intrinsic or use some uint(ushort()) casts to get the compiler to do the right thing, which means injecting the reverse_bits function in MetalBackend not the HLSL (as it has no such type).

Change 3415853 on 2017/05/01 by Ben.Marsh

	EC: Fix jobs never completing if a "Sync & Build" step fails. Dependent jobs should evaluate their run conditions as soon as the parent step finishes, rather than waiting for child job steps to be created.

Change 3416138 on 2017/05/01 by Ben.Marsh

	Fix Fortnite cook failures. Not sure what the exact problem is here, but my hunch is that discarded "const" causes blueprint compile failures due to not being able to connect output pins between nodes for overloaded functions, or something like that.

Change 3416309 on 2017/05/01 by Ben.Marsh

Change 3417983 on 2017/05/02 by Ben.Marsh

Change 3235308 on 2016/12/14 by Ryan.Vance

	#jira UEVR-478

	Monoscopic far field improvements

	Shader changes are now gated behind the read only cvar vr.MonoscopicFarField. Changing this requires a shader compile.
	Moved the mono rendering mode to the cvar vr.MonoscopicFarFieldMode. This is writable, so users can enable/disable mono rendering on the fly if the above cvar is enabled.
	Only write to the alpha channel in the mobile base pass if the object is opaque and MONOSCOPIC_FAR_FIELD is defined.
	Addressed code review comments.

	#jira UEVR-411: Finish renaming/removing/remodelling the remaining Oculus (Rift+GearVR) commands
	#jira UEVR-412: Rename and merge remaining Morpheus console commands
	#jira UEVR-417: Remove Exec from IHeadMountedDisplay

Change 3269971 on 2017/01/24 by Jeff.Fisher

	UEVR-498 move controller is missing world to meters
	UEVR-522 PS4 motion controller worldscale support.
	-Passing world to meters scale into getControllerOrientationAndPosition because the thing asking about it ought to be part of a world, and know what it should be.  This also avoids making PS4 motion controllers dependent on the HMD.  Note Google VR Controller doesn't do position, so doesnt' care about scale.  Oculus already had internal threadsafe tracking of world scale, so I left that.  Steam handles world scale below our input level.
	-Also adding PlayerIndex member to FSceneView so we can figure out which view the MotionControllerComponent should get its worldscale from for the late render thread update.
	#jira UEVR-498
	#review-3384107

Change 3288308 on 2017/02/06 by Jeff.Fisher

	UEVR-517 Detect MotionController Connectivity
	-PS4 can only track 2 controllers and 1 hmd.  Support for dealing with that is needed.
	-Also need to support multiple motion controller components mapped to a single controller.  Licencees have done that before.
	-Created a new interface IMotionTrackingSystemManagement, and implements it for PS4Tracker on PS4.
	-Created a MotionTrackedDeviceFunctionLibrary to expose that interface to blueprint.
	-With those one can enable and disable tracking on ps4 controllers and query their state to stay within the controller tracking limit.
	-PS4Tracker also keeps a blackboard of the enable/disable state so that one can enable or disable controllers that have not been connected yet, and have them enable tracking or not when they are connected.
	-DS4 controller no longer jumps back to 000 if it loses tracking.
	#review-3384107
	#jira UEVR-517

Change 3288309 on 2017/02/06 by Keli.Hlodversson

	Add file missing from CL#3257373.

Change 3288311 on 2017/02/06 by Jeff.Fisher

	UEVR-517 Detect MotionController Connectivity - Test content.
	-tm-motionControllers has a third mode where all playstation motion controllers for player 0 are availalbe.  You can toggle them to track or not with ctrl-P,G,L,R for pad, gun, leftmove, rightmove or with alt-P,G,L,R.  Ctrl tests doing so via MotionControllerComponent.  Alt tests doing so by player index and controller type enum.
	-ctrl-A disables tracking of all controllers
	-alt-A disables tracking of all controllers for player 0
	-ctrl-D toggles enabling new controllers by default
	-Also fixed one button not working in one of the other test modes for the Aim (gun) controller.
	-The controller 'models' have an arrow out the front.  It is black if disabled.  Red if enabled, but no tracker is active, yellow if tracked but inertial only, and green if fully tracked by the camera.
	-This logic is in the QA_MoCoAll blueprint.

Change 3291601 on 2017/02/07 by Jeff.Fisher

	UEVR-536 PSVR motion controller tracking problem with multiple controllers
	-Previous code called GetRelativeTransform from the render thread, but the game thread could update it at any time.  This caches that transform so that it can be safely used in the render thread.
	#jira UEVR-536
	#review-3384107 @Ryan.Vance

Change 3292460 on 2017/02/08 by Jeff.Fisher

	#jira UE-41604

	3278583
	pCustomPresent->AllocateRenderTargetTexture may return false, if we blindly return true we can end up with an invalid render target since the fall back sceneviewport will be skipped.

	* Pre VS2015 compilers don't like mixing wide and unmarked strings in concatenation. Unfortunately LOCTEXT hides the call to the TEXT macro, completely hinding the prefix (which only gets added to the first fragment.)
	* Switch apparently doesn't know how to format a size_t for analytics either.
	Also: Typo in backwards compatibility command name alias

Change 3337347 on 2017/03/08 by Jeff.Fisher

	UEVR-9 PSVR: Social Screen Support
	-Experimental social screen support for 4.16.
	-This does the basics of driving output through the Aux port in the proper format for display on the mirror monitor.
	-Only supports 30fps on the mirror monitor.  60fps will require the implementation of sony system dialogs to deal with incompatable system features (video streaming, remote play).
	-There is a project setting in Morpheus, under experiemental bEnableSocialScreenSeparateMode.  This must be set to true to use this feature.  When it is false we avoid allocating the back buffers.
	-MorpheusFunctionLibrary blueprints now have a node "SetSocialScreenMode" which can switch between SystemMirror (hardware supported mirroring), SeparateTest (alternates black and white), SeparateTexture (displays a texture, eg a render target, specified via blueprint), and SeparateMirror(puts the hmd render buffer on screen - which is both eyes, like a debug mode).
	-Also finally updated the bEnabled flag in project settings to tell people it's only for PC.

	Fixing Android compile issues. We can't wrap portions of a macro with a definie. This should probably be some sort of recursive macro thing since there's so much overlap. Good enough for now.

Change 3383353 on 2017/04/06 by Ryan.Vance

	Fixing include cycles.

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

Change 3121996 on 2016/09/12 by Ben.Marsh

	Add support for Visual Studio 2017 (aka "15"; assuming consistent naming with other versions until final name is announced).

	* Compiler, STL implementation and CRT are binary compatible with VS2015 (see https://blogs.msdn.microsoft.com/vcblog/2016/08/24/c1417-features-and-stl-fixes-in-vs-15-preview-4/), so no new third-party libraries needed so far. WindowsPlatform.GetVisualStudioCompilerVersionName() returns "2015" as a result.
	* Default compiler for compiling and generating project files is still VS 2015 for now. Pass -2017 on the command line to GenerateProjectFiles.bat to generate VS2017 projects. Projects generated for VS2017 will use the 2017 compiler by default.
	* Visual Studio source code accessor can talk to VS 2017 instances.
	* Added a VS2017 configuration for UnrealVS, and added precompiled vsix package.
	* Switched GetVSComnTools to check the SOFTWARE\Microsoft\VisualStudio\SxS\VS7 registry key rather than the individual product install registry key. "15" doesn't seem to have it's own "InstallDir" key, but this system seems to work for all versions of Visual Studio (including previous releases of VS Express).
	* Removed ATL dependency from VisualStudioSourceCodeAccessor. It's not installed with VS by default any more, and is only used for a couple of smart pointer classes.

	Tested running the editor and packaging TP_Flying for Win64. Packaging from the editor still defaults to using the 2015 compiler, so ConfigureToolchain() needs to be overriden from the .target.cs file if multiple Visual Studio versions are installed.

Change 3189363 on 2016/11/07 by Ben.Marsh

	Consolidate functionality for determining the path to MSBuild.exe to use for compiling UE4 tools into a single batch file (GetMSBuildToolPath) and fix "Clean" not working on PS4 due to include/library paths being set to something by the Visual Studio environment.

Change 3210598 on 2016/11/27 by Ben.Marsh

	UBT: Prevent the name of each file compiled being output twice on XboxOne. Compiler already outputs this string; the action doesn't need to.

Change 3210601 on 2016/11/27 by Ben.Marsh

	PR #2967: Add silent version of switch game version (Contributed by EricLeeFriedman)

Change 3210602 on 2016/11/27 by Ben.Marsh

	PR #2964: GitDependencies shouldn't try to clean up working directory files that are excluded or ignored (Contributed by joelmcginnis)

Change 3210605 on 2016/11/27 by Ben.Marsh

	UGS: Add a warning when syncing latest would remove changes that have been authored locally. Typically happens when working with precompiled binaries.

Change 3211656 on 2016/11/28 by Ben.Marsh

	UBT: Move ModuleRules and TargetRules into their own file.

Change 3211797 on 2016/11/28 by Ben.Marsh

	UBT: Remove utility functions from TargetRules for checking different classes of target types. Moving TargetRules to be data-only.

Change 3211833 on 2016/11/28 by Ben.Marsh

	UBT: Remove overridable configuration name from target rules. This feature is not used anywhere.

Change 3211859 on 2016/11/28 by Ben.Marsh

	UBT: Deprecate the GetGeneratedCodeVersion() callback in favor of a member variable instead.

Change 3211942 on 2016/11/28 by Ben.Marsh

	UBT: Remove legacy code which tries to change the output paths for console binaries. Output paths for monolithic binaries are always in the project folder now.

Change 3215333 on 2016/11/30 by Ben.Marsh

	UBT: Replace the GetSupportedPlatforms() callback on TargetRules with a SupportedPlatforms attribute. Since a TargetRules object can only be instantiated with an actual platform, it doesn't make sense for it to be an instance method.

Change 3215482 on 2016/11/30 by Ben.Marsh

	UBT: Remove the GetSupportedConfigurations() callback on the TargetRules class. A configuration is required to construct a TargetRules instance, so it doesn't make sense to need to call an instance method to find out which configurations are supported.

Change 3215743 on 2016/11/30 by Ben.Marsh

	UBT: Deprecate the TargetRules.ShouldCompileMonolithic() function: this function requires access to the global command line to operate correctly, which prevents creating target-specific instances, and does not use the platform/configuration passed into the TargetRules constructor.

	Rather than being a callback, the LinkType field can now be set to TargetLinkType.Modular or TargetLinkType.Monolithic from the constructor as appropriate. The default value (TargetLinkType.Default) results in the default link type for the target type being used. Parsing of the command-line overrides is now done when building the TargetDescriptor.

Change 3215778 on 2016/11/30 by Ben.Marsh

	UBT: Mark overrides of the TargetRules.GetModulesToPrecompile method as obsolete.

Change 3217681 on 2016/12/01 by Ben.Marsh

	UAT: Prevent UE4Build deleting .modules files when running with the -Clean argument; these files are artifacts generated by UBT itself, not by the exported XGE script.

Change 3217723 on 2016/12/01 by Ben.Marsh

	UBT: Run pre- and post-build steps for all plugins that are being built, not just those that are enabled.

Change 3217930 on 2016/12/01 by Ben.Marsh

	UGS: Add a perforce settings window, allowing users to set optional values for tuning Perforce performance on unreliable connections.

Change 3218762 on 2016/12/02 by Ben.Marsh

	Enable warnings whenever an undefined macro is used in a constant expression inside an #if or #elif directive, and fix existing violations.

Change 3219161 on 2016/12/02 by Ben.Marsh

	Core: Use the directory containing the current module to derive the UE4 base directory, rather than the executable directory. Allows UE4 to be hosted by a process in a different directory.

Change 3219197 on 2016/12/02 by Ben.Marsh

	Core: When loading a DLL from disk, convert any relative paths to absolute before calling LoadLibrary. The OS resolves these paths relative to the directory containing the process executable -- not the working directory -- so paths need to be absolute to allow UE4 to be hosted by a process elsewhere.

Change 3219209 on 2016/12/02 by Ben.Marsh

	Replace some calls to LoadLibrary() with FPlatformProcess::GetDllHandle(). The UE4 function makes sure that relative paths are resolved relative to the correct base directory, which is important when the host executable is not in Engine/Binaries/Win64.

Change 3219610 on 2016/12/02 by Ben.Marsh

	Add the -q (quiet) option to the Mac unzip command, since it's creating too much log output to be useful.

Change 3219731 on 2016/12/02 by Ben.Marsh

	UBT: Add option to disable IWYU checks regarding the use of monolithic headers (Engine.h, UnrealEd.h, etc...) and including the matching header for a cpp file first. bEnforceIWYU can be set to false in UEBuildConfiguration or on a per-module basis in the module rules.

Change 3220796 on 2016/12/04 by Ben.Marsh

	Remove PrepForUATPackageOrDeploy from the UEBuildDeploy base class. It never has to be accessed through the base class anyway.

Change 3220825 on 2016/12/04 by Ben.Marsh

	UBT: Change all executors to derive from a common base class (ActionExecutor).

Change 3220834 on 2016/12/04 by Ben.Marsh

	UBT: Remove the global CommandLineContains() function.

Change 3222706 on 2016/12/05 by Ben.Marsh

	Merging CL 3221949 from //UE4/Release-4.14: Fixes to code analysis template causing problems with stock install of VS2017.

Change 3222712 on 2016/12/05 by Ben.Marsh

	Merging CL 3222021 from //UE4/Release-4.14: Change detection of MSBuild.exe path to match GetMSBuildPath.bat

Change 3223628 on 2016/12/06 by Ben.Marsh

	Merging CL 3223369 from 4.14 branch: Use the same logic as GetMsBuildPath.bat inside FDesktopPlatformBase to determine path to MSBuild.exe

Change 3223817 on 2016/12/06 by Ben.Marsh

	Remove non-ANSI characters from source files. Compiler/P4 support is patchy for this, and we want to avoid failing prey to different codepages resulting in different interpretations of the source text.

Change 3224046 on 2016/12/06 by Ben.Marsh

	Remove the need for the iOS/TVOS deployment instances to have an IOSPlatformContext instance. The only dependency between the two -- a call to GetRequiredCapabilities() -- is now implemented by querying the INI file for the supported architectures when neeeded.

Change 3224792 on 2016/12/07 by Ben.Marsh

	UBT: Touch PCH wrapper files whenever the file they include is newer rather than writing the timestamp for the included file into it as a comment. Allows use of ccache and similar tools.

Change 3225212 on 2016/12/07 by Ben.Marsh

	UBT: Move settings required for deployment into the UEBuildDeployTarget class, allowing them to be serialized to and from a file the intermediate directory without having to construct a phony UEBuildTarget to deploy.

	Deployment is now performed by a method on UEBuildPlatform, rather than having to create a UEBuildPlatformContext and using that to create a UEBuildDeploy object.

	The -prepfordeploy UBT invocation from UAT, previously done by the per-platform PostBuildTarget() callback when building with XGE, is replaced by running UBT with a path to the serialized UEBuildDeployTarget object, and can be done in a platform agnostic manner.

Change 3226310 on 2016/12/07 by Ben.Marsh

	PR #3015: Fixes wrong VSC++ flags being passed for .c files (Contributed by badlogic)

Change 3228273 on 2016/12/08 by Ben.Marsh

	Update copyright notices for QAGame.

Change 3229166 on 2016/12/09 by Ben.Marsh

	UBT: Rewritten config file parser. No longer requires hard-coded list of sections to be parsed, but parses them on demand. Measured 2x faster read speeds (largely due to eliminating construction of temporary string objects when parsing each line, to trim whitespace and so on). Also includes an attribute-driven parser, which allows reading named config values for marked up fields in an object.

Change 3230601 on 2016/12/12 by Ben.Marsh

	Swarm: Change Swarm AgentInterface to target .NET framework 4.5, to remove dependency on having 4.0 framework installed.

Change 3230737 on 2016/12/12 by Ben.Marsh

	UAT: Stop UE4Build deriving from CommandUtils. Confusing pattern, and causes problems trying to access instance variables that are only set for build commands.

Change 3230751 on 2016/12/12 by Ben.Marsh

	UAT: Move ParseParam*() functions which use the instanced parameter list from CommandUtils to BuildCommand, since that's the only thing that it's instanced for.

Change 3230804 on 2016/12/12 by Ben.Marsh

	UBT: Add the IsPromotedBuild flag to Build.version, and only set the bFormalBuild flag in UBT if it's set. This allows UGS users to avoid having to compile separate RC files for each output binary.

Change 3230831 on 2016/12/12 by Ben.Marsh

	UGS: Warn when trying to switch streams if files are checked out.

Change 3231281 on 2016/12/12 by Chad.Garyet

	Fixing a bug where .modules files were getting put into receipts with their absolute path instead of their relative one

Change 3231496 on 2016/12/12 by Ben.Marsh

	Disable code analysis in CrashReportProcess; causes warnings when compiled with VS2015.

Change 3231979 on 2016/12/12 by Ben.Marsh

	UBT: Suppress LNK4221 when generating import libraries. This can happen often when generating import libraries separately to linking.

Change 3232619 on 2016/12/13 by Ben.Marsh

	Fix "#pragma once in main file" errors on Mac, which are occurring in //UE4/Main.

	#jira FORT-27627

Change 3186113 on 2016/11/03 by Mark.Satterthwaite

	Duplicate CL #3183807:
	Change the way we access the Metal viewport's backbuffer, to reduce possible causes of FORT-31649:
	- Added console variable "rhi.Metal.SupportsIntermediateBackBuffer" to control whether to use an extra render-target so we can support screenshots & movie capture, or render directly to the back-buffer to save memory & GPU performance. Still defaults to ON for Mac & OFF for iOS/tvOS.
	- Change the way we handle updates to the back-buffer size to ensure that the different threads access their intended version.
	#jira FORT-31649

Change 3186116 on 2016/11/03 by Mark.Satterthwaite

	Duplicate CL #3183823:
	Record Metal resource & state objects used in a command-buffer when rhi.Metal.RuntimeDebugLevel is set to 3 or higher. The object labels, types & descriptions will be printed on failure - if the object is deleted prior to this then we have a lifetime error and it will crash at this point and can be debugged further using our -metalretainrefs command-line option or Xcode's zombie-objects.

	Used to verify that FORT-31649 is not a simple resource lifetime error and thereby speed up Apple/vendor investigations.

Change 3209265 on 2016/11/23 by Arne.Schober

	DR - originally unshelved from 3153924 - Made Depth and Velocity Rendering Passes to use PSO only RHI interface,
	We are now passing down two structs that collect all the necessary information for the drawing policies to construct a PSO object.
	One during construction of the Policy, which contains information abouyt the CullMode, FillMode and PrimType.
	And another during rendering that passes infomation like BlendState and DepthStencilState down to the low levelrenderer into SetSharedState.
	Performance of the static drawlist ist slightly slower (less than 0.1ms on Consoles) due to some addtional branches and copies. The branches in the FDrawingPolicyRenderState will go away as soon as everything is converted to use the PSO interface.
	Performace of the GPU is slightly better due to less context rolls (mainly CullMode sorts in differently now)

	Changes from UE4-DX12:

	*** CL 3183818 ***
	Update D3D12 RHI to 4.14:
	 - Merged changes from Epic up until 10/20/16
	 - Fixed an issue where command allocators where resetting too early. I changed to aggressive command list batching by default now that more SubmitCommandListHint calls exist in the upper engine, we don't need to worry about starving the GPU. Fewer ExecuteCommandLists calls means better performance and fewer Signals() so this change provides a GPU perf win.

	I had to fix an issue with aggressive batching where we would sometimes hold on to a command list long enough (in the pending list) but hadn't executed it yet. The command allocator was being put back in the queue of allocators during ReleaseCommandAllocator() without a syncpoint set and was thus being reset too early. I added a simple counter to the command allocator so it could track how many command lists were using it. It doesn't need to be thread safe since only one thread uses a command allocator at a time.

	I also added some stats around the # command lists and # command allocators since it would be possible to leak command allocators now if it's pending command list count isn't decremented correctly. In that case we'd keep creating new command allocators and eventually run out of memory.

	-Remove clear during allocate in the FD3D12FastConstantAllocator and FD3D12FastAllocator. The supplied resource locations are assumed to be new and thus don't need to be cleared.

	-Cleanup D3D12RHI stats. There were some unused stats as well as some missing ones.

	-Mark shader resource table uniform buffers as dirty only when the shader changes. Cleanup SetComputeShader calls and Dispatch calls to not set/unset the CS for each Dispatch.

	-Remove unused Check SRV resolved code that epic added to the D3D11 RHI and was brought over. We dont need it and we won't use this.

	-Remove "always on" cycle counters for high frequency RHI methods like RHISetShaderTexture. These should use the engine's stat macros as they are removed on TEST + SHIPPING builds. On Xbox a significant amount of CPU time is spent in things like QueryPerformanceCounter even when STATS aren't enabled. Currently 1% of an entire capture on XBOX is spent inside this call.

	I improved and cleaned up high freqency call stacks like:
	 - RHISetShaderTexture
	 - RHISetShaderResourceViewParameter
	 - RHISetShaderParameter
	 - RHISetUAVParameter

	In general I moved to use templated functions, removed unused parameters, unnecessary copies, etc.

	-Change D3D12 PIX profiling enable/disable to match Xbox and handle logic in the UEBuildWindows.cs for UBT. Also add a static assert to inform the developer when PIX profiling is requested but the engine is compiling out draw events.

	-Resources should be associated with the rendering thread's frame that it's currently recording command lists for and they shouldnt be cleaned up until those command lists have been translated to D3D12 command lists on the RHI thread AND completed executing on the GPU. This was confirmed to resolve an issue where CBV resources were being released too early.

	This work involved a couple changes:
	1) Move the "frame" fence to be incremented on the rendering thread (during RHIAdvanceFrameForGetViewportBackBuffer()) so that resources that are deleted from the rendering thread are assosicated with the correct frame count
	2) Queue up a command from the rendering thread to signal the "frame" fence. It needs to be queued to ensure that it's signaled at the correct time on the RHI thread (after that frame's command lists have been executed).

	-Disable GRHIRequiresEarlyBackBufferRenderTarget. Metal/Vulkan/Xbox11.x already do this. This is used by the Slate renderer during BeginRenderFrame and avoids a SetRenderTargets call.

	-Enable GRHISupportsMSAADepthSampleAccess (used in the Editor). This was enabled for D3D11 on SM5, but not for D3D12.

	-Delay load D3D12.dll and add root signature 1.1 support.

	-Add explicit flush calls to improve resource barrier batching instead of implict flushes inside FConditionalScopeResourceBarrier and FScopeResourceBarrier. Also update those classes with const members.

	*** CL 3183824 ***
	Fix the D3D12 RHI after integrating UE 4.14 updates:
	- Fixed a bug where we would try to get the PSO of a nullptr in SetPipelineState if we needed to reset the current PSO on the cmd list.
	- Fixed a spelling error
	- Removed the need for bForceState, we use dirty bits now

	*** CL 3183830 ***
	- GetDebugFlags RHI extension, needed by XB1 movie player.
	- Only query memory info if stats are enabled
	- Add support for the engine's new RHISubmitCommandsAndFlushGPU function
	- Update CommitPendingPipelineState to be Graphics/Compute specific and avoid the need for a IsCompute parameter.

	*** CL 3183837 ***
	Made PipelineState caches contain pointers to FD3D12PipelineState objects to avoid issues with using pointers to after Find/Add to the maps. TMap indicates that the pointer to the value associated with a key "is only valid until the next change to any key in the map." The lifetime of the PSO pointers is managed by the low level caches (graphics and compute). Added stat for the number of Pipeline State Objects.

	*** CL 3183931 ***
	Update Windows D3D12 headers and libs to RS1 release bits (10.0.14393.0)

	*** CL 3183978 ***
	Update UBT Windows build settings:
	- Change D3D12 PIX profiling enable/disable to match Xbox and handle logic in the UEBuildWindows.cs for UBT. Also add a static assert to inform the developer when PIX profiling is requested but the engine is compiling out draw events.

	-Delay load D3D12.dll and add root signature 1.1 support.

	*** CL 3184132 ***
	Fix Xbox PSO cache code where it could leak PSOs. Related to change 3183837.

	*** Changelist 3211714 ***
	Update D3D12 RHI with fixes:
	 - Check if we can reserve slots in GatherUniqueSamplerTables
	 - DirtyState more often in StateCache
	 - Remove InternalSetSamplerState. The alternate function isn't used.
	 - Allow MRTClear for arrays with holes in them
	 - Fix uninitialized descriptors. This was causing a GPU hang on Xbox. We need to set dirty bits for resources bound to slots outside of the current descriptor table's range
	 - Cleanup SetDescriptorHeap code. Move setting descriptor heap logic to the descriptor cache since it also owns things like the sampler maps. Added members to the descriptor cache to track the last heaps that were set on the command list to avoid dirtying bit unnecessarily.
	 - Resource transitions: go through Common between queues (3D <--> Compute)
	 - Fix initial state for placed resources.
	 - Merging epic

Change 3209340 on 2016/11/23 by Ben.Marsh

	Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.

	Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.

	  * Every header now includes everything it needs to compile.
	        * There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
	        * There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
	  * Every .cpp file includes its matching .h file first.
	        * This helps validate that each header is including everything it needs to compile.
	  * No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
	        * You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
	        * There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
	  * No engine code explicitly includes a precompiled header any more.
	        * We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
	        * PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.

	Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

Change 3170391 on 2016/10/21 by Ben.Woodhouse

	Remove the wait on end of frame ensure, because we can't rely on all the the underlying codepaths to never miss a call to flush RHI resources. The consequences of missing a flush on a given frame are not serious now, since we enforce the synchronisation with a fence, preventing the rendering thread from getting too far ahead. We will simply accumulate resources for an additional frame when this happens.

	Fixed global distance field seam artifacts from landscapes with no subsections

Change 3182368 on 2016/11/01 by Daniel.Wright

	Dynamic Indirect Shadows for static meshes using distance fields
	* These Distance Field indirect shadows use the same tile culled and downsampled framework that capsule shadows use, with similar GPU cost
	* Individual StaticMesh assets can enable bGenerateMeshDistanceField to compute a distance field, without the memory cost of enabling for the whole project
	* New StaticMeshComponent properties bCastDynamicIndirectShadow and DynamicIndirectShadowMinVisibility
	* New WorldSettings property DynamicIndirectShadowsSelfShadowingIntensity which replaces the cvar
	* The GBuffer now stores HasDynamicIndirectShadowCasterRepresentation instead of HasHeightfieldRepresentation
	* DFAO from landscape is now done through the global distance field entirely.  Landscape contribution to the global distance field is deferred to attempt to workaround texture streaming issues.

	DR - [UE-32613] - OpenGL used to have custom code in the compiler to modify the source so that the same data and matricies can be used as DirectX, unfortunately that causes precission problem. Fortunately there is an extension available (glClipControl) which enables DirectX behaviour in OpenGL and it is widely supported. We only tested Linux and Windows and therfore only default enable on those platforms.

Change 3163524 on 2016/10/14 by Mark.Satterthwaite

	Bring over specific changes from Unicorn branch that increases the size of shader optional data so that it is considerably more useful.

Change 3163529 on 2016/10/14 by Mark.Satterthwaite

	Move the Metal shader source code and compilation path into the newly enlarged shader optional data.

Change 3163553 on 2016/10/14 by Mark.Satterthwaite

	Speculative fix for FORT-31590 also seen by a licensee - the Metal command buffer handler will be called from a dispatch queue thread that won't be registered with the stats system.
	#jira FORT-31590

Change 3163562 on 2016/10/14 by Mark.Satterthwaite

	Tidy up and extend the Metal debugging options:
	- Added rhi.Metal.BufferScribble which when enabled will fill freed buffer regions with 0xCD to help identify any areas where we are writing to a buffer while it is still being processed on the GPU.
	- Added rhi.Metal.BufferZeroFill which will zero-fill newly allocated buffer regions before any other data is read/written. Useful for catching cases where we might be reading uninitialised memory.
	- Added rhi.Metal.ResourcePurgeOnDelete which will purge the backing store of resources prior to releasing them back to the system or the respective pool. This will make any use-after-free conditions much more likely.
	- Added rhi.Metal.ResourceDeferDeleteNumFrames to defer releasing resources to the system or the resource pool by the specified number of frames (in addition to the current policy of waiting for the current end of frame & command-buffer completion). Useful for tracking down resource lifetime errors.
	- Fixed a number of bugs related to the modifications to vertex stream handling and addition of the SetShaderBytes API.
	- Track the start & end of FRingBuffer ranges - it appeared that the ring-buffer usage was invalid but it was in fact only my assumptions about the range that needed to be scribbled for rhi.Metal.BufferScribble. There is still the possibility that command-buffers that are implicitly parallelised by the driver may cause the ring-buffer range tracking to go awry - but with our data dependencies and the separation of the async. compute context I don't believe this is likely.
	- Fix up the "nometalv2" flag so that we can disable the features only available on iOS/tvOS-10/macOS-10.12 on newer devices to save having to reboot all the time.
	- Fixed the flickering geometry when enabling rhi.Metal.RuntimeDebugLevel=4 which breaks render passes into separate command-buffers - the occlusion query was waiting on the wrong command buffer in this case.

Change 3163752 on 2016/10/14 by Mark.Satterthwaite

	Add missing parenthesis to fix compile error on iOS.

Change 3164151 on 2016/10/16 by Benjamin.Hyder

	Submitting TM-AutoLOD level to QAGame

	#jira UE-29618

Change 3164190 on 2016/10/16 by Uriel.Doyon

	Materials now hold texture streaming data in the form of (UV scale X UV channel) for each texture.
	This data can be disabled through "r.Streaming.UseMaterialData"
	Defined a common framework in MeshComponent for texture streaming, used by both StaticMeshes and SkeletalMeshes.
	Simplified component interface for using the texture streaming build framework.
	Removed intermediate texture streaming build data from the static mesh components.
	Fixed shader compilation errors with the decals (from merge with main).

Change 3164636 on 2016/10/17 by Rolando.Caloca

	DR - vk - Fix validation spam

Change 3164679 on 2016/10/17 by Arne.Schober

	DR - [OR-28457] Part1, Scene View Refactoring - Removed Previous VewMatrices from SceneInfo and pass in Previous and Current ViewMatrices into Uniform Buffer creation to uniform UseCase for Shadows and CustomDepth, Fixed a Bug in Shadows with help of Daniel where the SceneView was copied unnecessary copied again. Also simplified the code in that area.

Change 3164705 on 2016/10/17 by Daniel.Wright

	When new levels are loaded, only the Indirect Lighting Cache Allocations intersecting the level's light probes are updated to minimize hitches.  This optimization requires a lighting build to compute PrecomputedLightVolume bounds.

Change 3164834 on 2016/10/17 by Daniel.Wright

	Support directional light dynamic shadows in any channel with forward shading, which can happen with multiple shadow casting stationary directional lights (even though only the lighting of one will appear)

Change 3164870 on 2016/10/17 by Arne.Schober

	DR - [OR-28457] Part2, Custom Depth Jitter - Allowed to overwite the viewconstant buffer in the custom depth pass. There ia also a new Project Setting available. The default constructor of the ContextDataType has been explicitly deleted to enforce compile errors when the templated code like the StaticMeshDrawList accidently tries to create a context without ViewUniformBuffer.

	DR - vk - First version of pooled occlusion queries

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

	DR - [UE-34481] - Extract all the State which is necessary to execute the DebugTextDrawingDelegate from the SceneProxy into its own Helpers to be drawn to the canvas later on.

Change 3127130 on 2016/09/15 by Mark.Satterthwaite

	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))). This change defines the missing overloads as returns with regular casts.

Change 3130547 on 2016/09/19 by Ben.Woodhouse

	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 3131118 on 2016/09/19 by Mark.Satterthwaite

	Second attempt - this time with the correct input types. 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))). This change defines the missing overloads as returns with regular casts.

	- Disable framebuffer recycling as its causing a hang

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.

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.

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.

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

Change 3088355 on 2016/08/13 by Max.Preussner

	Media Player Editor: Fixed Local file paths without file:// open when pressing Enter, but not when clicking Go button (UE-34643)

	#jira UE-34643

Change 3088331 on 2016/08/13 by Max.Preussner

	Media: Fixed Failing to load Precached Media Source (UE-34285)

	#jira UE-34285

Change 3088202 on 2016/08/12 by Zabir.Hoque

	Porting DX12 Fix from MS:

	Update D3D12 RHI for 4.13
	 - Fixed compiler errors with missing RHI methods. Fixed compiler warnings where names were hidding other variables.

	#jira UE-0

Change 3088149 on 2016/08/12 by Mark.Satterthwaite

	Duplicate CL #3087991:
	Initial AVFoundation implementation of Media Framework for Mac, iOS & tvOS.
	- Slight adaptation of AppleMovieStreamer to pick up movies from inside the GameContentDir on all Apple platforms.
	- Video playback occurs via AVPlayerItemVideoOutput's attached to the AVPlayerItem's output. This means gathering video samples is trivial.
	- Metal texture updates occur by wrapping the texture object provided by AVF - for Mac this is simple as it can bind to the IOSurface directly, for iOS/tvOS we have to create a CVMetalTextureCache and allocate our texture from there.
	- OpenGL and OpenGLES currently have to lock the pixel buffer and upload to a texture the old fashioned way - this should be revisited when there is time.
	- Subtitles/Captions are captured using AVPlayerItemLegibleOutput which also connects to the AVPlayerItem's output.
	- On Mac audio samples are returned by manually reading from the stream using an AVAssetReaderTrackOutput, including manual seeking and synching.
	- On iOS/tvOS the audio is played directly by AVPlayer because the IOSAudio system can't handle procedural buffers - otherwise it could reuse the Mac code.
	- AVFoundation does not support AVI - that's an obsolete Microsoft/Windows file-format.
	- Only 'file://' URLs are supported - streaming would require a totally different audio solution (using MTAudioProcessingTap) and has many more edge and failure cases that would need to be handled.
	#jira UE-34315

	Fix for crash when applying BSP materials
	This was caused by the renderthread dereferencing a reference to a ModelElement object which had previously been destroyed on the game thread.

	The reference to the ModelElement was solely used to dereference the irrelevant light GUIDs. The fix involves removing the reference and keeping a local copy of this array which is owned by the proxy. This is consistent with other proxies, e.g. Landscape, StaticMesh.

	PR #2516: CMake improvements and fixes (UE-22233, UE-32136).

	- Contributed by Nihlus.
	- Contains PR #1668 by mgerhardy

	Summary of changes (from PR):

	- Fixed an issue where CMake build files would contain invalid targets
	- Fixed an issue where CMake build files would generate without code completion data, making them useless in IDEs such as CLion.
	- Fixed an issue where invalid target platforms could fall through and cause issues with the file generation.
	- Improved code readability throughout the generator. Can still use some more polish.
	- Improved CMakeFile generation performance by approximately 25%. Before this patch, generating a CMakeFiles.txt for a small-ish project took 20s - by replacing most string concatenation with StringBuilders, it now takes approximately 15s. This should be more apparent in larger projects.
	- Improved commenting throughout the generator. As with readability, can still use some more polish.
	- Removed unused using statements.
	- Added the inclusion of a fake executable target to the CMake files. Some IDEs do not recognize header files that are not part of either an executable or a library. While this target will not build, it is neccesary in CLion.
	- Replaced all instances of String.Format with string interpolation expressions from C#6. This greatly improves readability, and helped me catch some bugs with the build targets.

	- When a sound buffer is flushed from audio device manager and tries to stop sounds using a resource, was possible for the async header parse task to be in-flight, which would cause a crash
	- Fix is to bring back the code to call EnsureCompletion on tasks in the FreeResoruces function of the sound source object. This will potentially encure a slight perf increase when stopping a sound but audio engine is now going to run on a separate thread, so shouldn't have a game-thread impact in non-editor builds.

	Fix "iOS Metal-based build crashes at launch with sub-levels":
	- Slate should not bind the null RHI texture from an unitialised texture atlas - atlases only have a valid texture pointer once an entry has been added to them and in the template projects an empty sub-level doesn't add anything.
	- To prevent this kind of bug resurfacing and being so hard to track down add Metal shader binding validation to our validation layer as Apple's is incomplete on iOS and won't warn us about nil texture usage which causes these GPU restarts. This requires reworking our vertex declaration handling to be more efficient so that we can cache the pipeline reflection data as well as the pipeline objects.

	Sequencer: Fixed sequencer adding spawnables into recorded worlds twice

	The issue here is that sequencer was re-evaluating itself with the current play world as the context, which also happened to be the world that it was trying to record. As a result, it ended up with the same sequence being played twice in the recording world.

	Added the ability to specify a playback context attribute for sequencer to use, and this no longer allows sequencer to play back in any worlds that are being recorded.

	Sequencer: Added support for montage based animation

	CL#3061714 :
	    Sequencer: Fixed anim trails not playing in full, sequencer-driven animation.

	    There were 2 issues here. Firstly, we were force-handling events and anim notifies in non-preview animation which caused undefined behaviour when the animation was also updated on tick. Secondly, On the very first frame of a game, sequencer can sometimes use the PreviewSetMatineeAnimPositionInner method because the actor it is referencing has not begun play yet. Unfortunately this function left the animation in a state where the 'real' animation update function wouldn't trigger any anim notifies properly.

	CL#3063015 :
	    Sequencer: Fixed anim notifies not working when playing animation on blueprint-driven skeletal meshes

	    We now inject a new animation position into the animation system, rather than trying to 'fake' events outside of the system. This allows for much more robust event triggering when playing back through sequencer. Previously, anim notifies for trail particles would be reset every frame due to TriggerAnimNotifies being called by the animation system, and sequencer. We now defer this responsibility to the animation system entirely during playback.

	CL#3068399 :
	    Sequencer: Changed animation tracks to allow more animation types (such as anim montages)

	      - APIs now accept UAnimSequenceBases rather than UAnimSequences to afford more flexibility

Change 3073542 on 2016/08/02 by Richard.TalbotWatkin

	Duplicated from Dev-Editor, CL 3072169.

	A couple of changes to the BSP code:
	* Fixed longstanding issue where sometimes BSP geometry is not rebuilt correctly after editing it.  This was due to poly normals not being recalculated after translating vertices in Geometry Mode.
	* Fixed corruption to FPoly::iLink as it is overloaded to have two meanings: when building BSP, it temporarily represents the surface index of the next coplanar surface (and adding a new BSP node uses this to determine whether a new surface needs to be added or not). In other operations it represents an FPoly index, in general this is used more in editor geometry operations.  This fixes various crashes which arose from rebuilding BSP resulting in invalid FPoly indices.

	Mesh paint bugfixes and improvements.

	Changes to RerunConstructionScript so that OnObjectsReplaced is called correctly on all components, whether they have been created by the SCS or the UCS. Previously, components created by the UCS were not being handled, and components created by the SCS were not always being matched.  Now a serialized index is maintained for UCS-created objects, which is matched after the construction scripts have been executed.

	This will fix issues with the mesh paint tool, and any other editor tool which hooks into the OnObjectsReplaced callback in order to update its internal cache of component pointers, for example, the component visualizer render list.

	Manually integrated some fixes from Dev-Blueprints

Change 3073311 on 2016/08/02 by Richard.TalbotWatkin

	Duplicated from Dev-Editor CL 3057868

	Spline component improvements, both tools and runtime:

	- SplineComponentVisualizer now works within the Blueprint editor. This works via a generic extension added to the base ComponentVisualizer class which correctly propagates modified properties from the preview actor to the archetype, and then on to any instances whose properties are at the default value.
	- The above feature required a breaking change to USplineComponent - namely, the three FInterpCurve properties have been collected together into a struct and added as a single property. This is so that changes to the length of one of the FInterpCurves marks all three as dirty and needing rebuilding.
	- Added a custom version for SplineComponent and provded serialization fixes.
	- Added a details customization to SplineComponent to hide the raw FInterpCurve properties.
	- Added a custom detail builder category which polls the SplineComponentVisualizer each tick and provides numerical editing for spline points which are selected in the visualizer.
	- Relaxed the limitation that SplineComponent keys need to have an increment of 1.0.  Now any SplineComponent key can be set.  The details customization enforces that the sequence remains strictly ascending.
	- Allowed an explicit loop point to be specified for closed splines.
	- Allowed discontinuous splines by no longer forcing the ArriveTangent and LeaveTangent to be equal.
	- Added some new Blueprintable methods for building splines with an FSplinePoint struct, which allows all of a spline point's properties to be specified, and added to the FInterpCurves sorted by the input key.
	- Fixed the logic which determines whether the UCS has modified the spline curves.
	- Added UActorComponent::RemoveUCSModifiedProperties, which allows a component to remove any properties from the cached list which it doesn't want to be considered as 'modified'. This is used to distinguish the case of properties preserved by the SplineInstanceDataCache from those genuinely modified by the UCS.
	- Fixed "Apply Instance Changes to Blueprint" so that edited spline data can be applied to the archetype.
	- Fixed some issues with the spline component visualizer to make it generate appropriate up vectors if scale and rotation are enabled.

	https://udn.unrealengine.com/questions/305440/shadowed-light-flicker-caused-by-floating-point-pr.html
	#jira UE-34052

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

	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.

	Added CompositeMode to SceneCapture2D, which can be used to addively accumulate or composite instead of the default overwrite behavior
	Added bCaptureOnMovement to SceneCapture, which can be disabled so the only source of scene capturing is a manual capture by calling CaptureScene()

	* Fixes WorldPosition in downsampled translucency
	* View uniform buffer parameters are now cached on the view, to allow recreating the uniform buffer without having to rebuild the entire struct.  Currently used by global distance field, downsampled separate translucency.
	* Fixed the downsampled translucency depth buffer being full res used together with a smaller color target, now they are both the downsampled res
