d16fb67979 Niagara Platform Set.
New feature for controling which platforms use certain aspects of Niagara.
Current users include;
- Emitter Enabled/Disabled switch
- System level scalability settings in EffectType and overrides in System.
- Emitter level scalability settings in EffectType and overrides in Emitter.

This entirely replaces previous Detail Level feature and all related code.

Now we allow users to select from EffectsQualitiy levels as a basic use case for scaling across platforms.
Further fine grained control can be acheived by setting per device profile overrides to this.
For example all Effects Quality levels could be enabled but Android could be specifically disabled. Or some subset of mobile devices.

TODO: Code is in place for this to cook out emitters but there are other impediments stopping this currently.
TODO: Sebastian has more UI changes incomming but as a v1.0 this is funtional.

5a0b8c9cd7 Added framepro.lScopeMinTimeMicroseconds to control the minimum recorded scope duration per platform.
framepro.ScopeMinTimeMicroseconds only applies when using framepro.startrec (not when captuing externally with the framepro ui or starting a capture through code).
Also got rid of framepro.startrecscopeoverride.

Set the default min scope to 25us.
Switch is set to 50us.
PC and Mac are set to 10us.

  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 3761437 by Guillaume.Abadie

	Optimises motion blur compute shader for consoles.

Change 3761483 by Guillaume.Abadie

	Fixes D3D11 RHI lying to dynamic resolution heuristic with t.MaxFPS.

Change 3761995 by Mark.Satterthwaite

	Add the Metal compiler path to the local .pch filename to avoid problems when Xcode moves.

Change 3761996 by Mark.Satterthwaite

	Emit more details when a pixel shader is found to have no outputs at all which Metal doesn't permit. More likely this is a bug in the shader compiler not configuring the in-out mask correctly...

	#jira UE-52292

Change 3761999 by Mark.Satterthwaite

	No need to avoid tessellation for FMetalRHICommandContext::RHIEndDrawIndexedPrimitiveUP anymore - that was from back when the tessellation logic was replicated in each RHI*Draw* implementation.

	#jira UE-51937

Change 3763111 by Richard.Wallis

	Fix for crash upon launching packaged game on Mac with Share Material Shader Code enabled.
	#jira UE-52121

Change 3763657 by Michael.Lentine

	Invalidate ddc for skeletal mesh render data so that the duplicated vertex render structures are properly serialized.

Change 3763727 by Jian.Ru

	Fix Player Collision view mode. It is caused by checking an uninitialized vertex buffer so the check always fail.
	#jira UE-52052

Change 3763738 by Guillaume.Abadie

	Implements SSR input post process material location.

Change 3764271 by Mark.Satterthwaite

	Allow ControlPointPatch lists to flow through MetalRHI as it was setup to handle this transparently - the VSHS compute shader will convert them to triangles to draw. Report the same warning as in the pipeline creation stage as this hasn't been formally validated.

	#jira UE-52454

Change 3764316 by Daniel.Wright

	Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density.  Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
	Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
	Reworked brick culling by error mechanism.  Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.

Change 3764318 by Daniel.Wright

	Missing file

Change 3764321 by Daniel.Wright

	Shader compiling memory optimizations
	* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
	* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
	* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
	* 13.8Gb written into worker input files -> 2.9Gb (4.7x less).  Global shaders are never batched when sent to SCW so unoptimized by these changes.

Change 3764595 by Daniel.Wright

	Added VolumetricLightmapDensityVolume asset icons

Change 3764701 by Michael.Lentine

	Add duplicated vertices merging for meshmerge.

Change 3766002 by Guillaume.Abadie

Change 3766007 by Guillaume.Abadie

	Oups.... Fixes compilation failure.

Change 3766697 by Guillaume.Abadie

	CL generated by python script.

Change 3767205 by Chris.Bunner

	Deferring FMaterial::RenderingThreadShaderMap update to render-thread rather than assumption commands have been flushed.

	#jira UE-50652

Change 3767207 by Chris.Bunner

	Clamp fetched texture coordinates to those available on the mesh.

Change 3767209 by Chris.Bunner

	PR #4203: Early-outs in UMaterialInstance parameter setters (Contributed by stefanzimecki)

	#jira UE-52193

Change 3767772 by Mark.Satterthwaite

	MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients. The Editor is already setup such that if the remote shader compiler is not configured & Xcode is not available locally the shader-compiler will be invoked to generate text shaders.

	#jira UE-52554

Change 3768604 by Guillaume.Abadie

	Polish up with new global shader function signature.

Change 3768993 by Guillaume.Abadie

	Fixes r.Upscale.Panini cvars

Change 3769478 by Mark.Satterthwaite

	Move the ue4_stdlib.metal & PCH into a temporary directory that exists for the lifetime of the SCW on the remote side as well as the local one and add this path as an include directory.
	#jira UE-52587

Change 3769703 by Mark.Satterthwaite

	For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
	For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.
	Remove the depth-offset hack from the depth-only vertex shader again.

	#jira UES-5651

Change 3769763 by Mark.Satterthwaite

	Handle swizzle's in the hlslcc fma identification pass so that we reduce the number of instructions and the platform compiler can't break the instructions up.

Change 3769849 by Mark.Satterthwaite

	Fix CIS error.

Change 3770517 by Richard.Wallis

	Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()).  Missing texture resource for binding.  Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like.  This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.

	#jira UE-51940

Change 3770688 by Uriel.Doyon

	Fixed texture resolution returning 0 when running blueprint construction scripts at cook time.

Change 3771115 by Mark.Satterthwaite

	Report errors from failed attempts to compile global shaders or we can't see why things fail on non-Windows platforms.

Change 3771263 by Mark.Satterthwaite

	Change the way ManualVertexFetch is enabled on Metal platforms so that it is enabled when targeting Metal v1.2 and higher (macOS 10.12+/iOS 10+). This brings iOS in the Desktop Forward renderer back into line with the Mac.

	#jira UERNDR-300

	Fixed some unnecessary PSO collisions.

Change 3777037 by Mark.Satterthwaite

	Remove incorrect change that caused a reference to "accurate::sincos" to appear in some Metal shaders rather than "precise::sincos".

Change 3777122 by Mark.Satterthwaite

	Back out changelist 3777037 - I'm blind and wasn't seeing the real problem was a stale shader cache...

Change 3777196 by Mark.Satterthwaite

	Fix text-shader compilation on iOS 10 - maybe iOS 9 too (untested!).

	We need our own make_scalar type-trait template for ue4_stdlib.metal so that we still compile with older iOS runtime compilers and we can't use as_type to directly implement the packHalf2x16/unpackHalf2x16 intrinsics for these older runtime compilers either.

Change 3779098 by Rolando.Caloca

	DR - vk - Fix query index

Change 3779275 by Mark.Satterthwaite

	Temporarily disable USE_OBJECT_COMPOSITING_TILE_CULLING  for Metal shader compilation only - other platforms are unaffected - as it isn't working properly for some reason. need to work out what's up but don't want Distance Fields to be completely snookered in the interim.

	#jira UE-52952

	#jira UE-52952

Change 3784741 by Mark.Satterthwaite

	More Metal debugging commandline options "-metalfastmath" & "-metalnofastmath" to force fast-math on or off for all shaders, must be using runtime-compiled shaders (i.e. -metalshaderdebug or r.Shaders.Optimise=0) to take effect.

Change 3788536 by Mark.Satterthwaite

	Track whether the Metal shader uses the discard_fragment function as when this is used but without any other outputs we know we need to bind at least one render-target or a depth-stencil surface but we don't know which. This lets us correctly error when we encounter a shader with no outputs at all which Metal doesn't permit.
	#jira UE-52292

Change 3788538 by Mark.Satterthwaite

	Let's try mitigating UE-46604 on Nvidia by retaining resource references in the command-buffer. This shouldn't be necessary and isn't typically on other vendors but we haven't been able to reproduce this reliably enough to get to the bottom of it.

Change 3791884 by Daniel.Wright

	Added BP setter for LowerHemisphereColor

Change 3791886 by Daniel.Wright

	Added LightmapType to PrimitiveComponent
	* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent.  Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
	* ForceSurface replaces bLightAsIfStatic
	Improvements to Volumetric Lightmap quality needed for static geometry
	* Stationary light shadowing is now dilated inside geometry
	* Now doing two dilation passes since samples near geometry see inside due to ray start bias
	* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
	Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Change 3792256 by Guillaume.Abadie

	Fixes a bug where permutation was not actually serialised in FShader, so was ending up recompiling shader at every load.

Change 3792884 by Marcus.Wassmer

	Copying //UE4/Partner-AMD to Dev-Rendering (//UE4/Dev-Rendering)

Change 3793200 by Marcus.Wassmer

Change 3793206 by Brian.Karis

	Added color grading control BlueCorrection to correct for artifacts with "electric" blues due to the ACEScg color space. Bright blue desaturates instead of going to violet.

	Added color grading control ExpandGamut which expands bright saturated colors outside the sRGB gamut to fake wide gamut rendering.

	ACES changes.

Change 3793344 by Marcus.Wassmer

Change 3794285 by Guillaume.Abadie

Change 3794307 by Guillaume.Abadie

	Resaves uassets that were modified between 3789648 and 3794285

Change 3794627 by Mark.Satterthwaite

	Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:

	- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
	- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
	- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
	- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
	- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
	- Add tvOS support.

	Next up, put this into MetalRHI and start fixing all the fallout.

	Move StructuredArchive implementation into Core, so primitive types can implement serialization overloads for it.

Change 3770875 by Steve.Robb

	Redundant UScriptStruct::PostLoad removed, which was causing a race condition in async loading.  This was re-establishing the CppStructOps, but that is unnecessary because native classes cannot change as a result of a load - only BP structs can, and they don't have CppStructOps.

Change 3772167 by Ben.Marsh

	Add a context-free binary formatter that can serialize tagged data. This functions as a lower-overhead binary intermediate format for JSON data.

Change 3772248 by Steve.Robb

	ThreadSanitizer fixes to FMalloc call counters.

Change 3772383 by Ben.Marsh

	Separate archive metadata from FArchive into FArchiveContext, so it can be safely exposed to consumers of FStructuredArchive.

Change 3772906 by Graeme.Thornton

	TextAssetCommandlet - Utility commandlet for testing/converting to text asset format

Change 3772932 by Ben.Marsh

	Fix "String:" prefix not being stripped from escaped string values.

Change 3772942 by Graeme.Thornton

	Add experimental setting to enable in-editor text asset format functionality
	Add "export to text" option into the content browser asset actions context menu

Change 3772955 by Ben.Marsh

	Add a new "stream" compound type to FStructuredArchive, which allows serializing a sequence of elements similarly to an array, but without serializing an explicit size. Allows passing through data to an underlying binary archive without breaking compatibility.

Change 3772963 by Ben.Marsh

	Allow querying record keys and stream lengths from annotated archive formatters, since these archives have markup for field boundaries.

Change 3773010 by Graeme.Thornton

	Added CORE_API to FArchiveFromStructuredArchive
	Gave text asset format experimental option a slightly less random tooltip comment

Change 3773057 by Ben.Marsh

	Add a flag to FArchive to determine whether the archive is text (IsTextFormat()).

	Add support for seeking within FArchiveFromStructuredArchive. For text formats, data is serialized to an in-memory buffer, with names and objects serialized as indices into an array. For non-text formats, data is serialized directly to the underlying archive.

	Also rename FStructuredArchive::TryEnterSlot() to TryEnterField().

Change 3773118 by Steve.Robb

	TSignedIntType and TUnsignedIntType type traits for getting an integer type of a given size.

Change 3773122 by Steve.Robb

	TAtomic fixes for pointer arithmetic.
	TSignedIntType used instead of reimplementing its own trait.

Change 3773123 by Steve.Robb

	Unit tests for TAtomic.

Change 3773138 by Steve.Robb

	Run numeric tests on integer types instead of basic tests.
	Fix for compiler warnings when subtracting from unsigned atomics.

Change 3773166 by Steve.Robb

	Refactoring of arithmetic operations into its own class, then basing the pointer and integral versions on that.

Change 3774216 by Gil.Gribb

	UE4 - Fix rare crash in the pak precacher immediately after unmounting a pak file.

Change 3774426 by Ben.Marsh

	Copy all C# tools to a staging directory before compiling them. This prevents access violations when compiling tools like iPhonePackager that reference DotNETCommon, and ensures we strip NotForLicensees folders out of them all.

	See: https://answers.unrealengine.com/questions/726010/418-will-not-build-from-source.html

Change 3774658 by Ben.Marsh

	Improve error reporting while generating intellisense for project files. Include the name of the target being compiled, and allow project file generation to continue without it.

Change 3775141 by Ben.Marsh

	Always output HTML5 diagnostics at "information" verbosity, to avoid every line being prefixed with "WARNING:" and screwing up the EC postprocessor.

Change 3775459 by Ben.Marsh

	Removing .NET Framework Perforce DLL as runtime dependency of engine third party library. The actual library is linked statically.

Change 3775522 by Ben.Marsh

	UGS: Treat .uproject and .uplugin files as code changes.

Change 3775597 by Ben.Marsh

	Fix post-build steps for plugins not being executed.

	#jira UE-52754

Change 3777895 by Graeme.Thornton

	StructuredArchiveFromArchive - An adapter class for wrapping an existing FArchive with a structured archive

Change 3777931 by Graeme.Thornton

	Refactored FArchiveUObjects serialization code into some static helpers
	Added FArchiveUObjectFromStructuredArchive which allows the adaption of a structured archive into an FArchive that supports the extra UObect serialization functions for weak/soft pointers

Change 3777942 by Graeme.Thornton

	Added missing CORE_API to FStructuredArchive::FStream
	Added FStructuredArchive::FSlot insertion operator for char
	Added specialization of TArray<uint8> serializer for structured archives which serializes the contents as one value

Change 3778084 by Graeme.Thornton

	Adding FPackageName::GetTextAssetPackageExtension() to access the file extension we use for text asset files

Change 3778096 by Graeme.Thornton

	Add a constructor to FArchiveUObjectFromStructuredArchive that takes a slot and passes it to the base class

Change 3778389 by Josh.Engebretson

	Fix an optimization issue with CPU benchmarking
	Add better support for debugging/testing local rocket builds

	UDN Link: https://udn.unrealengine.com/questions/400909/command-scalability-auto-gives-inaccurate-cpu-benc.html

	#jira UE-52192

Change 3778701 by Josh.Engebretson

	Ensure plugin content folders are mounted consistently.  Fixes TryConvertFilenameToLongPackageName failing to work on plugin assets

	UDN Link: https://udn.unrealengine.com/questions/276386/tryconvertfilenametolongpackagename-fails-for-plug.html

	#jira UE-40317

Change 3778832 by Chad.Garyet

	Adding enterprise path support for PCB's for UGS

Change 3780258 by Graeme.Thornton

	TextAssetCommandlet - Accumulate timings for loading packages and saving packages

Change 3780463 by Graeme.Thornton

	CryptoKeys improvements
	 - Enable CryptoKeys plugin by default
	 - Attempt to inherit settings from the old system by default
	 - Hide ini/index encryption settings from packaging settings and just inherit previous values into new system

	Minor UBT change to remove a trailing comma from the end of encryption/signing key binary strings

Change 3780557 by Ben.Marsh

	Fix LoginFlow module not being precompiled for the binary release.

Change 3780846 by Josh.Engebretson

	Improve filename to long package name resolution when provided a relative path

Change 3780863 by Ben.Marsh

	UAT: Add a better error message when a C# project has an invalid reference.

Change 3780911 by Ben.Marsh

	Update the BuildEditorAndTools.xml script to allow submitting archived binaries to Perforce.

	The "Submit To Perforce For UGS" node creates a zip of all the binaries that have been built, and submits it to the stream specified by the 'ArchiveStream' argument.

Change 3780956 by Josh.Engebretson

	Add support for ! (RemoveKey) config command to UBT

	UDN Link: https://udn.unrealengine.com/questions/397267/index.html

	#jira UE-52033

Change 3782957 by Robert.Manuszewski

	UE4 - Fixed a linear search in EDL that caused performance problems for very large maps.

Change 3784503 by Ben.Marsh

	Optimizations for FStructuredArchive:

	* Store the depth explicitly in element objects, to avoid having to loop through the scope stack to find it.
	* Prevent shrinking of arrays when removing elements.
	* Add an inline allocator to the scope and container stacks.

Change 3784700 by Ben.Marsh

	Remove the inline allocator from FStructuredArchive; checking whether the inline or backup allocator is being used is slower than just allocating up-front.

Change 3784989 by Ben.Marsh

	Compile out all the FStructuredArchive validation code when WITH_TEXT_ARCHIVE_SUPPORT = 0.

Change 3786860 by Gil.Gribb

	UE4 - Remove no buffering flag from windows async IO because it disabled the disk cache entirely.

Change 3787159 by Ben.Marsh

	Guard against UE4.0 backwards compatibility path when determining if an engine is a source distribution.

Change 3787493 by Josh.Engebretson

	Parallel pak generation now uses MaxDegreeOfParallelism option which is now set to the number of CPU cores
	Moved cryptography settings parsing out of threaded CreatePak method to avoid concurrency issue in ConfigCache.TryReadFile
	Fix for multiple threads parsing ini keys (PR 3995)

	#PR 3995
	#jira 52913
	#jira 49503

Change 3787773 by Steve.Robb

	Fix for missing final values from FOREACH_ENUM_ macros.

Change 3788287 by Ben.Marsh

	TBA: Add checks in debug builds that key names in maps and records for FStructuredArchive are unique.

Change 3788678 by Ben.Marsh

	Fix compile error due to inability to instantiate TArray<> of forward declared struct. Convert set of key names to an array to avoid including Set.h in public header for FStructuredArchive.

Change 3789353 by Graeme.Thornton

	Removed unused/rotten modes from TextAsset commandlet.
	Used existing "-iterations=n" switch to control a global iteration over the given command. Useful for performance testing.

Change 3789396 by Ben.Marsh

	Move code to validate container keys/sizes into DO_GUARD_SLOW checks, and allocate container metadata instances dynamically to fix problems with references to things not declared in headers that can't be included from StructuredArchive.h

Change 3789772 by Ben.Marsh

	Always strip trailing slashes from the end of paths specified by .build.cs files; they can cause quoted paths to be escaped on the command line.

Change 3790003 by Ben.Marsh

	TBA: Rename FStructuredArchive::EElementType::Object to FStructuredArchive::EElementType::Record.

Change 3790051 by Steve.Robb

	PIE is disabled during a hot reload.
	Hot reload in editor is disabled during PIE.
	Hot reload from IDE is deferred until after PIE is exited.
	Compiling multiple times before a hot reload (e.g. compiling multiple times in PIE) will now load the most recent change.

	#jira UE-20357
	#jira UE-52137

Change 3790709 by Steve.Robb

	Better move support for TVariant.
	EVariantTypes switched over to using an enum class to aid debugger visualization.

Change 3791422 by Ben.Marsh

	TBA: Return the type of a field from an annotated archive formatter at the point that we enter it, rather than querying all the time.

Change 3791489 by Graeme.Thornton

	TBA: Change StructuredArchiveFromArchive adapter to use the archive.Open() result directly, now that it's a slot and not a record

Change 3792344 by Ben.Marsh

	Improvements to base64 encoding library.

	* Now supports encoding and decoding with ANSICHAR and WIDECHAR implementations.
	* Added support for decoding base-64 blobs without padding marks.
	* Added support for decoding into pre-allocated buffer.
	* Added constexpr functions for determining the encoded and maximum decoded size of an input buffer.
	* Prevent writes past the end of allocated buffer (no longer need to manually remove padding bytes).

Change 3792949 by Ben.Marsh

	TBA: Rename FAnnotatedArchiveFormatter to FAnnotatedStructuredArchiveFormatter.

Change 3794078 by Robert.Manuszewski

	Fixing a crash that could happen when FGCObjects were constructed and destructed when shutting down the engine

	#jira UE-52392

Change 3794413 by Ben.Marsh

	TBA: Remove the element type parameter to SetScope(). It isn't really needed; we can just assume the element ID correctly identifies the item on the stack.

Change 3794731 by Ben.Marsh

	TBA: Optimize creation of stack elements for empty slots in FStructuredArchive. This saves a lot of bookkeeping when serializing a large number of individual fields. Since only one slot can be active at a time (and it only exists temporarily, until we write into it), we can just store the element ID assigned to it in a member variable.

Change 3795081 by Ben.Marsh

	UBT: Move LinuxCommon.cs into Platform/Linux folder.

Change 3795137 by Ben.Marsh

	UBT: Allow modules to specify private compiler definitions from the build.cs file, only visible within that module (via the "PrivateDefinitions" property).

Change 3795247 by Ben.Marsh

	Fix missing header when creating a new interface from the editor new code wizard.

	#jira UE-53174

Change 3796025 by Graeme.Thornton

	Fixed some deprecated "Definitions" warnings in OpenCV build files

Change 3796103 by Graeme.Thornton

	Disable experimental text asset option - it does nothing useful yet.

Change 3796157 by Graeme.Thornton

	Fix path type mismatch in visual studio source code accessor meaning that the DTE comms wouldn't identify a running instance of VS as having the current solution open.

	#jira UE-53206

Change 3796315 by Ben.Marsh

	Move Formatter to the correct position for initializer.

	#jira UE-53208

Change 3797082 by Ben.Marsh

	UAT: Work around for exception thrown by launching cook with "-platform=Android_ETC1 -targetplatform=Android -cookflavor=ETC1". Anrdoid_ETC1 is not a valid platform (it's a cook platform), and can't be parsed by UAT.

	#jira UE-53232

Change 3799050 by Ben.Marsh

	Make UnrealPak.version files writable for Mac and Linux.

Change 3801012 by Graeme.Thornton

	UGS: Show an in-place error panel when a project fails to open, allowing the user to retry and have their tabs saved instead of creating a modal dialog.

Change 3624590 by Steve.Robb

	AddReferencedObjects now generates a compile error with containers of UObject*s where the UObjectType is forward-declared, as these which won't be added to the reference collector.
	Tidy-up of existing calls to AddReferencedObjects.

Change 3629473 by Ben.Marsh

	Build: Rename the option for embedding source server information in PDB files for installed engine builds.

Change 3632894 by Steve.Robb

	VARARG* macros deprecated and usage replaced with variadic templates.

Change 3640704 by Steve.Robb

	MakeWeakObjectPtr added, which deduces a TWeakObjectPtr type from a raw pointer type.
	Fix to TWeakObjectPtr's constructor which implicitly removed const.
	Fixes to everything which didn't compile as a result.

Change 3650813 by Graeme.Thornton

	Removed FStartupPackages and associated code

Change 3651000 by Ben.Marsh

	Return the stack size from FPlatformStackWalk::CaptureStackBacktrace() rather than checking for the first null pointer, to prevent truncated callstacks if parts of the stack are zeroed out.

	#jira UE-49980

Change 3690842 by Steve.Robb

	FPlatformAtomics::AtomicRead added - needs optimizing.

Change 3722698 by Steve.Robb

	VS debugger visualizers for TAtomic.

Change 3732270 by Steve.Robb

	Relaxed stores and loads.

Change 3749315 by Graeme.Thornton

	If UAT is invoked with platforms in both the -platform and -targetplatform command line switches, build using all of them rather than just the ones in -targetplatform

	#jira UE-52034

Change 3750657 by Josh.Engebretson

	Fixed issue when debugging editor cook/package and project launch operations

	#jira UE-52207

Change 3758514 by Steve.Robb

	Fixes to FString::Printf having non-literals being passed as its formatting string.

Change 3763356 by Steve.Robb

	ENamedThreads::RenderThread and ENamedThreads::RenderThread_Local encapsulated by getters and setters.

Change 3770549 by Steve.Robb

	Removal of obsolete PLATFORM_COMPILER_HAS_DEFAULTED_FUNCTIONS and PLATFORM_COMPILER_HAS_AUTO_RETURN_TYPES.
	Tidy up of existing code which uses it.

Change 3770553 by Ben.Marsh

	Adding structured serialization API to Core/CoreUObject for use with text-based assets.

	* FStructuredArchive abstracts an archive which is made up of compound types (records, arrays, and maps). Values are stored in slots within these types.
	* Records are string -> value dictionaries where the key names can be compiled out in non-editor builds or when WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Maps are string -> value dictionaries where the key names are present regardless of the build type.
	* Proxy objects are defined to express the context for serialization (FStructuredArchive::FRecord, FStructuredArchive::FArray, FStructuredArchive::FMap, FStructuredArchive::FSlot) which allows basic validation through static typing. These objects act as lightweight handles, and can be cheaply constructed and passed around on the stack. Most serialization to and from the archive is done through these objects.
	* Runtime checks perform additional validation to ensure that serialized data is well formed and written in a forward-only manner, regardless of the underlying archive type.
	* The actual input/output format is determined by a separate interface (FArchiveFormatter). Context validation (always causing matching LeaveArray for every EnterArray, etc...) is done by FStructuredArchive, so implementing these classes is fairly trivial. FArchiveFormatter can be de-virtualized in non-editor builds, where WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Includes implementations of FArchiveFormatter for binary and JSON formats.

Change 3771105 by Steve.Robb

	Deprecation warnings for PLATFORM_COMPILER_HAS_AUTO_RETURN_TYPES and PLATFORM_COMPILER_HAS_DEFAULTED_FUNCTIONS.
	Fix for incorrect warning formatting on Clang platforms.

Change 3771520 by Steve.Robb

	Start moving Clang-using platforms' pre-setup stuff into a Clang-specific header.

Change 3771564 by Steve.Robb

	More common macros moved to the Clang pre-setup header.

Change 3771613 by Steve.Robb

	EMIT_CUSTOM_WARNING_AT_LINE moved to ClangPlatformCompilerPreSetup.h.

Change 3772881 by Ben.Marsh

	Add support for serializing FName and UObject through FStructuredArchive.

	In order to allow custom linker behavior when serializing objects:

	* The constructor to JSON input formatter now takes a delegate to convert a string object name into a UObject pointer.
	* The constructor to tagged binary formatter takes a delegate to serialize a UObject pointer into any form it chooses (likely an integer index into the import table)

	Object and name types are stored as strings in JSON, using an "Object:" or "Name:" prefix to differentiate them from regular strings. Any strings that already contain one of these prefixes are prepended with a "String:" prefix (as is any string that already has a "String:" prefix).

Change 3772941 by Graeme.Thornton

	Make build work when including StructuredArchive.h from core container types
	Added standard header to new files
	Add structured archive serializer for TArray
	Fix bug in structured archive where containers weren't being popped from the scope stack

Change 3772972 by Ben.Marsh

	Add an adapter which presents a legacy FArchive interface to a FStructuredArchive slot.

	Data is serialized into this slot as a stream of elements; raw data is buffered up into fixed size chunks, names and objects are serialized separately.

	When used with FBinaryArchiveFormatter, this should result in all data being passed through to the underlying archive in a backwards compatible way, wiith no additional bookkeeping fields.

Change 3773006 by Ben.Marsh

	Rename FStructuredArchive::FRecord::EnterSlot() to EnterField().

Change 3773013 by Steve.Robb

	bUseInlining target rule added to UnrealBuildTool, which defaults to true, to allow inlining to be disabled for debugging purposes.

Change 3774499 by Ben.Marsh

	Minor fixes for FStructuredArchive related classes:

	* Text-based archive formats are now compiled out when WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Fixed issue with FTaggedBinaryArchiveFormatter state becoming corrupted when looking ahead at field types.
	* FArchiveFieldName constructor is now explicit, to fix cases where strings were being passed directly to serialize functions.

Change 3774600 by Ben.Marsh

	Add CopyFormattedData() function, which can copy data from one formatter to another. Add a test case to SerializationAPI that converts from data -> JSON -> binary -> JSON -> data.

	This function can be used to implement a generic visitor pattern, by implementing a FArchiveFormatter which receives the deserialized data.

Change 3789721 by Ben.Marsh

	TBA: Split FTaggedBinaryArchiveFormatter into separate classes for reading and writing.

Change 3789920 by Ben.Marsh

	TBA: Support automatic coercion between any numeric types in tagged binary archives. Also report the smallest type that can contain a value, rather than just in32/double.

	#jira UECORE-364

Change 3789982 by Ben.Marsh

	TBA: Change FStructuredArchive::Open() to return a slot, rather than a record, to make it easier to implement a raw FArchive adapter.

Change 3792466 by Ben.Marsh

	TBA: Better handling of raw data in text based assets. Short sequences of binary data are Base64 encoded as a single string. Longer sequences are stored as an array of Base64 encoded lines, push a SHA1 hash to detect cases where the data was merged incorrectly.

	In order to allow inference of the correct type for a field, other fields called "Base64" will be escaped to "_Base64", and any field beginning with "_" will have an additional underscore inserted. Reading files back in reverses these transformations.

Change 3792935 by Ben.Marsh

	TBA: Rename FArchiveFormatter to FStructuredArchiveFormatter for consistency with FStructuredArchive.

Change 3795100 by Ben.Marsh

	UBT: Rename the ModuleRules Definitions property to PublicDefinitions, to make its semantics clearer.

Change 3795106 by Ben.Marsh

	Replace all internal usages of ModuleRules.Definitions, and replace it with ModuleRules.PublicDefinitions.

Change 3796275 by Ben.Marsh

	Fix paths to Version.h includes from resource files.

Change 3800683 by Josh.Engebretson

	Remove WER from Mac and Linux crash reports in favor of unified runtime-xml format
	#jira UE-50073

Change 3803545 by Steve.Robb

	TWeakObjPtr const-dropping assignment fix.
	Fixes to change.

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

Change 3780878 by Nick.Darnell

	UMG - Providing more information when the compile fails to find a bindable widget.


Change 3780855 by Gil.Gribb

	UE4 - Fixed a linear search in EDL that caused performance problems for very large maps. Saves half the load time in FN-BR.


Change 3780803 by Thomas.Sarkanen

	Dont create animation tasks for skeletal meshes that have no anim instance

	This avoids some wasted work for non-animated attachments, such as pickaxes

	#jira FORT-61523 - Don't create anim worker tasks if no AnimBP


Change 3780741 by Yenal.Kal

	#jira FORT-60177

	Fixed the bug where the anim branching points (begin and end) may be triggered twice incorrectly.

Change 3780663 by Gil.Gribb

	UE4 - Batching for audio thread commands.


Change 3780466 by Ben.Marsh

	Add error matcher for generic Microsoft errors (eg. 'cl : Command line error D8049 : command line too long to fit in debug record')

Change 3779937 by Nick.Darnell

	UMG - Adding an accessor on UUserWidget to get the owning player state easier, since it's a common operation.


Change 3779858 by Sam.Zamani

	#http
	use separate "-multihomehttp" instead of "-multihome" for routing http socket

	#jira FORT-61666
	#tests none

Change 3779288 by Michael.Trepka

	Changed FMacConsoleOutputDevice::Serialize to use FString's GetNSString() instead of converting the string using FPlatformString::TCHARToCFString to make it safer in case of garbage text passed in Data

	#jira FORT-59762

Change 3779062 by Mike.Fricker

	Merged CL 3731188 and CL 3733311 from //UE4/Dev-Editor.

	----

	Improve responsiveness of Open Asset dialog.

	On large projects, there's a noticeable delay when opening and searching/filtering assets.

	Stopwatch measurements on my machine (seconds for ~122,000 assets):
		before	with this CL
	ctrl-P	1.4	0.45
	search	1.8	0.55

	CollectionManagerModule was the main culprit for search/filter slowness.

	Open Asset delay was due to filtering out plugin content. We were doing a lot of redundant work for what is essentially a read-only operation.


Change 3778954 by Nick.Darnell

	Slate - Making the Horizontal and Vertical analog keys configurable in the navigation config.  Tweaking how fast the navigation is with the analog stick, trying to tune the feeling.


Change 3778896 by Ben.Marsh

	Separate FNameEntrySerialized from FNameEntry, rather than deriving from it. It has to be allocated differently, and many fields cannot be shared between the two.

	#jira

Change 3778807 by Ben.Marsh

	Fix Tencent include paths not registering if workspace directory contains a space.

	Tencent include paths currently have a trailing backslash, and this is surrounded by quotes if the root directory contains a space. The backslash is interpreted as escaping the trailing double quote.

	#jira

Change 3778686 by Luke.Thatcher

	 Reduced impact of dynamic vertex buffer RHI stall in D3D12
	 - In most cases we can avoid the stall if the vertex buffer has never been used before.
	 - Only when a buffer has an existing SRV do we need to stall.

	 - Also, delete copy and move constructors of FD3D12ResourceLocation. Moving or copying an instance of this class leads to double free crashes, so this is now a compile error rather than a runtime crash.

	This saves an average of 2ms frame time in a StW lastperftest replay, with r.screenpercentage 10.

	#jira FORT-61390

Change 3778679 by Thomas.Sarkanen

	Fix Linux server crash - dont attempt to run threaded work in a single-threaded environment

	We dont attempt to run animation update work multi-threaded in the same conditions that we didnt attempt to run animation eval work previously.

	#jira FORT-61548

Change 3778591 by Ben.Woodhouse

	Add build config to FPSChart HTML output

	#jira FORT-56478

Change 3778175 by ben.marsh

	Remove code to trigger an ensure on Arxan guards. We already send analytics for this, and don't need this legacy path. There is a large number of incoming ensures with this callstack that are clogging up crash reporter.

	Will remove all the surrounding code in a later update to a development branch.

	#jira

Change 3777750 by Chris.Gagnon

	- Slate now supports a CustomBoundary Navigation type wich allows a custom handler if the boundary is hit.
	  - This provides the ability to have normal navigation while within the boundary and the custom function only on the boundary.

	Header (uasset) and export (uexp) files will now be compared seperately when running cook commandlet with -diffonly to avoid situations where a mismatch in size of the header produces more differences between exports.

	+ Renamed ini setting to ignore header differences from SkipHeaderDiff to IgnoreHeaderDiff


Change 3772867 by Thomas.Sarkanen

	Nativization now correctly generates and builds code for "Client" builds

	Overall this is a bunch of hacks, but necessary for nativization to work at present. Once the cooker and UAT both have a concept of "Client" targets, this can be implemented properly.
	Instead of building to a "Client" directory, we build to "Game" for client-only platforms (like PS4, XboxOne)
	Also we need to add "Client" targets to the whitelist for the nativized assets plugin, as UBT still thinks it is building for "Client"

	#jira FORT-52823 - Nativizing Player Animation Blueprints

	Cook commandlet will now report full property name when running a diff against the existing cook (-diffonly)


Change 3772359 by Thomas.Sarkanen

	Improvements to the Cpp backend to allow VC++ to compile nativized code more effectively

	Added a new scoped helper to wrap areas of the code in PRAGMA_DISABLE_OPTIMIZATION. This helps with functions that are large tables or long lists of initializations.
	Split anim node initialization up into functions, called from a seperate function dedicated to initializing anim nodes. This splits the 5k+ line constructor into mutiple smaller functions, which the compiler has no problems with.
	Overall (along with splitting up the anim BP into functions in the asset) this reduces compilation time for the worst-case compilation unit from ~11m 40s to ~2m 32s.

	Fixes to enable auto-nativization for animation blueprints

	For blend profiles in particular, I've added subobject support to the fake import table building for nativized assets:
	- In FEmitterLocalContext::FindGloballyMappedObject, if we dont find the referenced asset then we traverse the object's outer chain if it is a subobject. We add it to UsedObjectInCurrentClass if we find its outer.
	- Updated the structure used to build the fake import table to include a specified outer. Beforehand we assumed that all objects referenced by the import table were 'top-level'.
	- Updated the fake import table building code in FLinkerLoad::CreateDynamicTypeLoader() to use the new specified outer if found. This asserts if it couldnt find the outer in the already-parsed dependencies (as it reverse-iterates). If in the general case thius turns out to be a problem we can move this to a two-pass system.

	Disabled fast-path optimization when running a native anim BP, as native code is faster!

	Fix initialization order warnings


Change 3741370 by Ryan.Gerleve

Change 3740209 by Nick.Darnell

	UMG - Finishing the ability to add a "Custom" method for Navigation.  Currently the editor implementation leaves me wanting, but it works for now.  You can put the name of a function to call (needs to match a signature that returns a UWidget).


Change 3740207 by Nick.Darnell

	Slate - Navigation attempts when the user claims they are doing custom or explicit, if those methods don't return a valid widget, we don't treat it like the attempt failed and fallback to default navigation methods.  Instead we use it as a trigger to indicate that no navigation should occur and treat it like a stop.

Change 3736109 by Michael.Trepka

	Updated FMallocLeakDetectionProxy to not use a critical section internally on top of thread safety measures performed by FMallocLeakDetection and the underlying FMalloc implementation. The improvements are biggest on Mac, in particular in low framerate situations, as Metal RHI uses malloc heavily on multiple threads, but it's also a nice 10% improvement on a high end PC.

Change 3712515 by Ben.Woodhouse

	CSV profiler GPU and pre-declared stat support
	- refactor the GPU profiler so it's no longer dependent on the stats system and can work in Test builds
	- 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 3712297 by Mike.Fricker

	Fixed huge client hitch when applying changes to in-game options
	- Every component was being re-registered when r.SimpleForwardShading was updated by the scalability system, even if the value hadn't changed.  Now, it only re-registers components if the value changes on the fly.  (e.g. when turning Shadows off or on PC)

	Fixed issue where this could fail if a messagebox was spawned early during initialization


Change 3708830 by Bob.Tellez

	#UE4 Commandline switches/options are no longer detected when found between quote characters. This causes options from not being incorrectly detected when passed in as a value from another options. i.e. -Option="-log" no longer causes -log to be picked up. This removes the syntax of specifying parameters like "Option=Value", which should now be replaced with -Option="Value"

	#jira FORT-57833

	Added engine code for drawing a debug 2D box.
	Added engine code that allows for Keyboard Shortcuts to be special characters like backslash \.

	-- Code --
	DrawDebugHelpers:
	DrawDebugCanvas2DBox() - Added this to allow us to draw debug 2D boxes.

	RemoteConfigIni:
	SpecialCharMap - Updated this TCHAR* property to be in the right order so you can use special characters like backslash as keyboard shortcuts.

Change 3701976 by Michael.Noland

	Editor: Rewrote CallInEditor support and promoted it so it can be used on functions in any class, not just blueprints derived from AActor:
	- CallInEditor used on native UFUNCTION() declarations will now show up without having to make a BP subclass
	- CallInEditor can now be used as a top-level keyword in the UFUNCTION() declaration (e.g., UFUNCTION(Category=CoolCommands, CallInEditor))
	- Now shows each function as a separate button, placed in the category associated with the function
	- The button strip entry is now searchable by function name or tooltip
	- Prevented operating on functions that have parameters or return values, which would crash before
	- Removed the duplicate copies of properties placed in the Blutility section
	- Added a scoped transaction around CallInEditor execution
	- Allowed functions to be marked as CallInEditor in addition to custom events (currently we don't allow editing category or tooltip on custom events...)

	Editor: Moved Experimental/EarlyAccessPreview details customizations up to UObject so it can be used on any class, not just actors/components

	Edigrating CL# 3374995, 3375121, and 3375308 from Dev-Framework to FN main

Change 3700836 by Bob.Tellez

	Modified commandline parse function, to detect when it is incorrectly parsing a parameter, from within another parameters value (not exhaustive).

	For example, this commandline only contains the parameter ParamA. It should not be possible to parse ParamB, as it is part of ParamA's value:
	-ParamA="-ParamB=Value"

	#jira FORT-57833

Change 3700821 by Bob.Tellez

	Merging CL#3461205 from //UE4/Dev-Core

	Speculative fix #2 for a server crash/assert. If the timing is right, it's possible for the server to try to re-load a placed-in-map actor that was previously garbage collected. This was happening because CanClientLoadObject was always returning true for these (null) objects, even if the NetGUID corresponded to a map actor that shouldn't be loaded. Also added/improved some logging that will help in case this doesn't fix the issue.

Change 3690227 by David.Ratti

	Added optional TWeakObjectPtr parameter to packagemap functions GetOrAssignNetGUID, SUpportsObject. This allows you to pass in a weak ptr for an object if its already created. If you pass in null, the functions will create them internally.

	Cherrypick TAA refactor 3512696 and TAA fix 3668108

	#jira FORT-56303

Change 3681494 by Bob.Tellez

	#UE4 IsLoadedByEditorPropertiesOnly is not working properly so I removed it from FullLoadAndSave


Change 3681342 by Bob.Tellez

	#UE4 Added a FullLoadAndSave option to cooking, which simply loads all content then saves it to avoid the overhead of managing which packages need to be cooked. Large perf improvement for those who cook by the book and can fit the entire game in memory


Change 3681014 by Yenal.Kal

	#jira FORT-56209
	#jira FORT-56272

	Fixed a bug in the ability system where the ability ended callbacks could cause the ability end to be called again in the same call stack even though the ability is activated only once.

	This was happening because we were broadcasting the event before we decrement the active count.

Change 3680739 by Michael.Trepka

	Warn about NaN float literal values when translating HLSL to Metal instead of failing, plus added more detailed warning/error messages for NaN and unhandled values

	#jira UE-50650 Fix memory/event leak in USoundWave::AudioDecompressor

	Fix is to only delete the decompress/pre-cache task in game thread during FinishDestroy and not allow sounds to start playing unless the precache task has finished.

Change 3672464 by Lukasz.Furman

	removed recast layers crash tracking code

Change 3672153 by Daniel.Lamb

	Added some debugging code to help track down why shaders are hashing poorly.


Change 3671498 by Luke.Thatcher

	 [~] Modify new frame syncing to reduce performance regression seen when the game is running over budget.
	 - Rather than forcing a flip sync after we kick off one frame early, we just continue to kick frames if we time out. This allows the game thread to get ahead when we're over budget.
	 - The game thread will naturally resync with the vsync when we return to being in budget.

	#jira FORT-55842

Change 3671079 by Ryan.Gerleve

	Fix an edge case where the PackageMap on the server would try to resolve objects from default NetGUIDs even if their outer has already been garbage collected. This could lead to a completely unrelated object being returned instead of null, leading to asserts and potentially other issues.

	#jira FORT-55763


Change 3670487 by Zak.Middleton

	Optimize some low level details of UNetConnection::ClientHasInitializedLevelFor() and UNetDriver::IsLevelInitializedForActor(). Add cached WorldPackage for NetDriver to avoid repeated GetOuterMost() and Casts. Remove rendundant virtual GetWorld() calls, and mark UNetDriver's version "final" to let it optimize away virtual call. Made UNetConnection::ClientVisibleLevelNames a TSet instead of TArray, since it is searched frequently when there are streaming levels present.

	#jira FORT-55999

Change 3670351 by Zak.Middleton

	Back out changelist 3669817 (networking optimizations). Would rather have more testing before it goes to Release-Next. Will resub just for main and RP.

	fixed overlapping index buffers when static mesh exports both convex and simple collisions for navigation
	#jira UE-50370

Change 3665374 by Mike.Fricker

	Fixed server crashing after hotfixes have re-imported curve table data
	- The hotfix system is capable of replacing the content of a UCurveTable on the fly
	- If any systems had references to inner curves on that curve table, they would become invalid
	- This needs to be fixed in 1.6.4 (tonight) and also in 1.7

	#jira FORT-55792

Change 3665063 by Daniel.Broder

	Fixed crash in GameplayTagQueryCustomization when choosing "Save and Close" on GameplayTagQuery after setting a query due to nullptr NotifyHook in CloseWidgetWindow.

	Added additional if (StructPropertyHandle.IsValid()) wrappers and one check(StructPropertyHandle.IsValid()); the former to be consistent with other code and prevent possible crashes, the latter to at least catch the cause of a possible crash properly without having to change the code more significantly to handle it gracefully.

	Also changed some if( X ) to if (X) to match coding standards and provide consistency within the file.


	Michael, I'm Reviewing you on this fix since you brought this change over from Framework.  And Marc because you reviewed him on that change.

	#UE4 #NoReleaseNotes #RNX

Change 3664916 by John.Abercrombie

	Copy CLs 3383318 & 3388506 from //Orion/Main/Engine/Source/Runtime/Engine/...
	- Been testing with this for a while now
	- This change makes particle effects show up on the current frame's pose for skel meshes as well

	Removed my StopAllMontagesByGroupName temp hack

	CL 3383318
	Delay dispatching of AnimEvents (Notifies and Montage Events) until after we receive an updated animation pose (if applicable).
	This fixes AnimNotifies playing particle effects using a socket location using last frame's pose. Now they use the current frame's pose.

	CL 3388506

	Delay clearing of MontageInstances and triggering 'OnAllMontageInstancesEnded' until all Montage Events have been dispatched.
	Also fix SkelMeshComponent ticking on dedicated servers when rejoining in progress.

	#jira FORT-55102 - Server Crash UAnimInstance::StopAllMontagesByGroupName

Change 3780616 by Gil.Gribb

	Fixed and reenabled r.DelaySceneRenderCompletion

Change 3778979 by Gil.Gribb

	UE4 - Improved the performance of grass updates and added the ability to not do all of them every frame.

Change 3778200 by Nick.Darnell

	UMG - Making it possible to cancel delays and all animations on widgets.  Useful when destroying a widget and needing to stop any async state.

Change 3777612 by Zak.Middleton

	Perf: Added option to CharacterMovementComponent to skip immediate forward prediction for proxies on the frame they receive a network update (bNetworkSkipProxyPredictionOnNetUpdate). This avoids all forward prediction sweeps and floor checks on those updates. Intermediate frames will interpolate with prediction. This can also be disabled globally with the CVar "p.NetEnableSkipProxyPredictionOnNetUpdate 0".
	Added NetworkSmoothingDisableProxyPredictionForPawnLOD to force disabling full simulation for LOD >= this value (currently 3, so bottom 75 pawns). This takes precedence over current distance and view angle checks for prediction (mesh interpolation is untouched).

Change 3774338 by Ben.Woodhouse

	Convert the D3D12 PSO caches to use RwScopeLocks. This change is courtesy of a shelf from Gil, plus a couple of minor fixes.
	Saves up to a millsecond of frame time in CPU-bound scenarios

Change 3773462 by Gil.Gribb

	UE4 - Add particle batching. This is disabled by default but can improve thread scheduling when there are lots of very fast particle systems.

Change 3771375 by Hongyi.Yu

	Fixed the crash where ability components are unregistered and then re-registered, which usually happens in PIE.

Change 3771368 by Ben.Zeigler

	#jira UE-52670 Add project setting bValidateUnloadedSoftActorReferences that is true by default to match current behavior. If you set it to false it will no longer load packages to look for soft actor references when deleting/renaming actors.

Change 3771173 by Seth.Weedin

	Auto manage attachment support for AudioComponent- An opt-in feature that allows AudioComponents to cache their AttachParent/AttachSocket and only attach themselves when playing audio, detaching after playback is completed. Set to false by default.

Change 3768811 by Ori.Cohen

	Change animation scale collision code so that it uses the physics asset.

Change 3768148 by Brian.Bekich

	Fix muting being unable to find remote player controller

Change 3768117 by Ori.Cohen

	Prevent pawn collision from updating during animation

Change 3766554 by Gil.Gribb

	UE4 - Added a new option to add and remove from static draw lists on demand. This is off by default.

Change 3766427 by Nick.Darnell

	Slate - Finally adding Opacity to SWidget.  Any widget can now be alpha animated at will, no more need to waste overhead by wrapping things with SBorder or making them userwidgets just to be able to animate a fade.

Change 3761682 by nick.darnell

	Athena - Introducing a way to interrupt the request to scroll and item into view.  In cases where you're animating, quickly showing and hiding, with the item widgets unavailable for a few frames, you enter cases where the deferred navigation is resolved after you've canceled showing a dialog stealing focus.

Change 3761416 by Ben.Zeigler

	#jira UE-52287 Prevent cook metadata like DevelopmentAssetRegistry.bin from being packed into a shipping game, by moving it into a Metadata subdirectory and updating deployment scripts to avoid that directory.
	Right now it doesn't package them at all, we could change it to package them as Debug Non-UFS if desired
	Change it so the asset audit UI will only load DevelopmentAssetRegistry.bin files, the cooked registry files don't have enough information any more to be useful
	Remove ability for runtime game to load DevelopmentAssetRegistry.bin, this ended up not being useful

Change 3750998 by Ethan.Geller

	#jira FORT-60191 Allow -audiomixer command line arg to work on all platforms.

Change 3749540 by Marc.Audy

	SignificanceManager now takes viewpoints in as TArrayView instead of const TArray&

Change 3748102 by Marc.Audy

	Allow cheat cvars to work in Test builds by default
	Can be overriden by defining ALLOW_CHEAT_CVARS_IN_TEST as 0 in Target.cs files

Change 3744756 by Bart.Hawthorne

	Upgrade Oodle to version 2.5.5. Also, iOS, Android, and Switch platforms have been added. The new dictionary has been generated with old and local captures.

Change 3741168 by Max.Preussner

	MediaUtils: Fixed movies not playing properly in Shipping builds

Change 3739256 by Jian.Ru

	Set distance field self-shadow bias without recreating all render states

Change 3730756 by Ben.Woodhouse

	HISM optimization:
	Gil's change to skip trees with only one level of hierarchy (working around badly tuned content issues)
	Change vert threshold to 2K.
	1-2ms renderthread win without impacting GPU when rendering point lights

Change 3724029 by Zak.Middleton

	Increase allowed time for movement substep duration. Don't want to lower between 2 iterations, as this is not used much in practice other than deflection and movement mode changes, and that will change behavior (lose momentum). This new setting will absorb longer hitches in the common case (moving without collision or falling).

Change 3723985 by Marc.Audy

	SignificanceManager PostSignificanceUpdate functions can now be executed sequentially on the game thread as well as concurrently in the parallel for (old behavior)

Change 3722910 by Jian.Ru

	Amortize shadow cache update caused by resolution change
	Changed to use view distance vs. view space z when calculating whole scene shadow resolution which is less sensitive to camera rotation

Change 3718247 by Yenal.Kal

	Fixed the bug where the gameplay effect durations can show incorrect values after rejoin or after server time drifting away from the client.

Change 3716343 by Jamie.Dale

	Adding Korean and Turkish to the localization automation


Change 3710534 by Uriel.Doyon

	Texture streaming optimization where a maximum texture resolution for each level streaming data is computed per view.
	This is used to cull irrelevant levels and reduce the async task number of iterations.
	The culled size is defined by the new r.Streaming.MinLevelTextureScreenSize.

	This requires to remove primitives with big UV density from the level data.
	Those primitives get moved to the dynamic lists.
	This is controlled by r.Streaming.MaxTextureUVDensity

Change 3707207 by David.Ratti

	Remove look ahead-vectors prediction in FNetViewer. This (requires) a line trace which is not desirable or really accurate anymore. This saves us a line trace per connection per multicast rpc.

	unify reliable multicast rpc handling: these now do relevancy checks and are not sent to non relevant clients

Change 3706272 by Thomas.Sarkanen

	Added utility/math functions to aid in optimizing anim blueprints

	Added VectorLengthXY to get the 2D length of a 3D vector. Avoids unecessary conversions.
	Added polar->cartesian->polar conversion helper functions for expensive frequently-used anim graph functionality.

Change 3706159 by David.Ratti

	PlayerState/ASC replication optimizations from Polge: this puts the net update frequnecy on player state back to 1hz while forcing netupdates on the player state actor when the ability system component needs to update

Change 3692891 by David.Ratti

	Optimizations for UNetConnection::ClientHasInitializedLevelFor: build acceleration map of actor outer's (ULevels) -> Visibility bool. Existing logic stays the same.

Change 3691392 by Aaron.McLeran

	#jira UE-50628 Fix audio trying to sync load bulk data with EDL enabled

	- Fix log error in BulkData.cpp
	- Make the first stream chunk be force inline payload in bulk data flags so it loads immediately vs in async IO system
	- Make audio stream chunks get as close to 256 k chunks as it can, zero-pad rest to be 256 k aligned
	- Fix up DDC key, serialize AudioDataSize separately from chunk DataSize

Change 3682683 by Zak.Middleton

	Add bOnlyTickMontageOnDedicatedServer variable to AnimInstance, to avoid anim bp updates on dedicated server. Turn on to fix hitching from queued ServerMove() calls, and some free perf during all montages on the server.

Change 3678771 by Ori.Cohen

	Added the ability to turn on stack walk during hitching vs lightweight stats

Change 3676363 by Ori.Cohen

	Added the ability to get callstacks as part of hitch detection

Change 3674877 by Keith.Judge

	Move definition of GFailedToFindParamCollectionBufferQueue to ShaderBaseClasses.cpp so that all targets can successfully compile.

Change 3672515 by Bob.Tellez

	Added code to play wind particle effects

Change 3670909 by Zak.Middleton

	Fixed ForcePositionUpdate() not calling CheckJumpInput(). Added "p.NetForceClientServerMoveLossPercent" cvar to simulate loss of client->server movement RPCs (without hosing the rest of networking).

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

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

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

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

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

	* Planar reflections are now supported in splitscreen

Change 3360758 on 2017/03/23 by Daniel.Wright

	[Copy] Added new light property bCastVolumetricShadow, which defaults to true for directional and sky lights, but false for point / spot lights as supporting volumetric fog shadowing has significant GPU overhead

Change 3360762 on 2017/03/23 by Daniel.Wright

	[Copy] Texture flags are now properly routed to RHICreateTexture3D from the render target pool

Change 3360768 on 2017/03/23 by Daniel.Wright

	[Copy] Distance field cvar comments

Change 3360782 on 2017/03/23 by Daniel.Wright

	[Copy] Disabled selection color on Volume materials

Change 3360795 on 2017/03/23 by Daniel.Wright

	[Copy] Volume materials now specify Albedo and Extinction, which is more intuitive than Scattering and Absorption.  Albedo is [0-1] reflectance, while Extinction is a world space density.

Change 3360799 on 2017/03/23 by Daniel.Wright

	[Copy] Cinematic scalability levels get 2x volumetric fog resolution in x and y

Change 3360806 on 2017/03/23 by Daniel.Wright

	[Copy] Fixed volumetric fog being offset when viewport min is not 0

Change 3360809 on 2017/03/23 by Daniel.Wright

	[Copy] Volumetric fog now adds a bias to the inverse squared light falloff denominator, prevents extreme aliasing from the hotspot.  Can be controlled with r.VolumetricFog.InverseSquaredLightDistanceBiasScale.

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

	Updated items from original shelved version by Mark Satt:

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

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

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

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

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

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

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

Change 3367877 on 2017/03/28 by Brian.Karis

	DR - Copy 3371640 (fix mem leak)

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

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

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

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

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

Change 3372740 on 2017/03/30 by Chris.Bunner

	[Experimental] Partial compute post process pipeline (r.PostProcess.PreferCompute).

	DR - Fix static analysis

Change 3374544 on 2017/03/31 by Richard.Wallis

	FShaderCache Parallel-Context-Aware Merged with FShaderCache Single Library.

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

	Fixes scene captures ordering's backward compatibility.

	Before, 2d scene captures were rendered before cube scene captures. The CaptureSortPriority broke backward compatibility by settings this new member to 0 in the USceneCaptureComponent's constructor. Since it is a higher come first policy, this CL set the default of this value to 1 in USceneCaptureComponent2D's constructor.

	#jira FORT-36375

Change 3280579 on 2017/01/31 by Ben.Zeigler

	Remove ForEachProperty and switch AssetManager to use TPropertyValueIterator instead. Code review changes to TPropertyValueIterator.
	Add InitializeAssetBundlesFromMetadata to AssetManager which parses AssetBundles metadata at load/save time and uses that to assign asset references to specific bundles.
	Add RecursivelyExpandBundleData to allow recursively acquiring bundle dependencies.
	Add AssetBundles to the PropertyMetadata list. Sorted list and fixed some comment typos.
	Change it so the DataAsset factory won't show blueprintable native classes as valid, the editor doesn't like it when you have both blueprinted and non-blueprinted assets of the same base class.
	Change AssetPtr.LoadSynchronous to be const and to behave the same as Get(). This was a licensee complaint and the old behavior to null out the reference because of a transient load error can cause data loss.

	Delay initialization of asset registry tag filter list until it is needed, to make sure it catches modules that were loaded after the asset registry module. Fixes issues with tags not inherting to child classes

Change 3278592 on 2017/01/30 by Ben.Zeigler

	Add TPropertyValueIterator to replace ForEachProperty. This is a recursive iterator instead of a predicate search, and also allows extracting the property chain, which I need for metadata parsing.
	AssetManager has an example of both uses, will delete ForEachProperty tomorrow.

	#jira FORT-36662 Return streamable manager to always use hard references, weak references do not work during AddReferencedObjects at all, because of the unreachable flag that is set during GC. This returns the behavior of forcing assets to be "Force Deleted" if they were loaded by asset manager.

	Fix crash/data loss when a Pin's DefaultObject points to an ObjectRedirector. FixObject will return redirectors so you need to correct for that

Change 3276073 on 2017/01/27 by Ben.Zeigler

	Add some utility functions to core asset manager and streamablemanager and fix various editor interactions.
	Add startup and cook interaction hooks to AssetManager directly and call them form Engine in addition to the game-specific hooks.
	Add concept of BulkScanning to AssetManager, use this when scanning many directories.
	Fix issues with string asset references being wrong for blueprint classes, this would be easier if the assetdata pointed to the class and not the possibly-missing blueprint.
	Change StreamableManager to keep referenced objects as weak pointers. These pointers are effectively soft in the editor, hard outside of the editor. By storing them as raw pointers it was difficult to guarantee their safety without causing issues with deleting assets.

Change 3276058 on 2017/01/27 by Ben.Zeigler

	#JIRA FORT-34794

Change 3236747 on 2016/12/15 by Ben.Zeigler

	Fortnite fixes for asset manager/async loading changes
	FortItemDefinitions now async load needed assets on demand. Currently this is only loading AttributeTemplate, which may not even be in use
	The blueprints needed for weapons are now async loaded when the player puts them on their quickbar, instead of being loaded once and staying in memory forever
	FortAssetManager is now being used in parallel to the loading code in FortGlobals, I will remove the FortGlobals code in the next checkin once I know things are working
	Change it so the MissionEventNames are loaded asynchronously when clicking the picker, this code was half completed already so I finished it up
	Change it so GameplayCueNotifies get async loaded on demand instead of async loaded at startup, this improves startup load times
	Change it so the CommonUIModule uses the global assetmanager instead of a passed in StreamableManagerHandler
	Item json changed because it got resorted, no actual json changes other than a few cosmetics that were added yesterday
	Change it so FortItem implements the mcp item interface directly, instead of FortWorldItem and FortAccountItem implementing it separately

Change 3236746 on 2016/12/15 by Ben.Zeigler

	Add ProcessAsyncLoadingUntilComplete which will process async loading until a predicate is true or time runs out
	Change streamable manager to return a handle structure, that can be used to block or poll as needed. Active handles will keep objects in memory even after the load finishes
	FStreamableManager::SynchronousLoad now does high-priority-async-load-and-wait instead of doing a full async flush/static load object if asynch loading is in progress, this should make stalls much shorter when sync loading a single asset
	Deprecate some of the StreamableManager functions now that handles exist. The fact that SynchronousLoad kept an object from ever GCing was not expected behavior by most users

	Add Experimental feature AssetManager, which is a global singleton that supports loading assets on demand. It is disabled by default
	Add concept of PrimaryAssetID which is a Type:Name pair that globally identifies an asset. This is returned by GetPrimaryAssetId on UObject and is needed for the asset manager to work
	Add PrimaryAssetData class, which supports the primary asset and bundle concepts natively
	Add concept of an AssetBundleEntry/Data, which is a scoped map from name -> list of assets. If you modify an AssetBundleData it will get baked into the asset registry at runtime

	Fix KismetSystemLibrary and GameplayCueManager to use the new streaming functionality

Change 3234031 on 2016/12/13 by Ian.Fox

	#UE4, #XMPP - Finish libstrophe MUC (Multi-User Chat) implementation

Change 2750026 on 2015/11/02 by Thomas.Sarkanen

	Anim Multithreading: thread-safety refactor

	Segregated access to various parts of anim update data by spitting off a new proxy class (FAnimInstanceProxy) containing all data accessed in Update() and Evaluate() passes. Gated access to the proxy data on the game thread in a number of ways:

	- Explicit access via GetValueOnGameThread() - this blocks on any existing task, completes and then allows control to return to the accessing function. This allows stuff like Blueprints to continue to operate as normal.
	- Explicit access via GetValueOnAnyThread() - this ensures that in the limited set of circumstances we need this (Blueprint pure functions mostly) that conditions are met about concurrent access.
	- Deprecating many APIs on UAnimInstance that should not be used (and in fact are not used at present, happily).

	Derived classes of UAnimInstance can override the creation of the proxy class to create their own type. We do this for UAnimSingleNodeInstance etc.

	Any API deprecation should continue to function - no functions have been removed yet. The only things that are not backwards-compatible are direct access to some public member variables for which there is no way to support (e.g. via references, for example UngroupedActivePlayerArrays).

	Some APIs have been changed to more specifically represent the dependencies involved. For example TickAssetPlayerInstance() used to take a UAnimInstance*, only to use it to simply queue notifies. This has been deprecated and replaced with a new FNotifyQueue API. FNotifyQueue also uses a thread-safe FRandomStream instead of FMath::Rand.

	Many changes are due to substituting accessor functions for direct variable access.

	Removed 'service' tick group as we no longer need to segregate the running of our parallel update.

	Anim nodes that need to do some game thread-side update should register for a pre-update callback delegate in the proxy. See FAnimNode_AnimDynamics for an example of this.

	Moved UpdateActiveVertexAnims into FAnimRuntime so I can subsume some of the code that was in USkeletalMeshComponent::EvaluateAnimation into UAnimInstance (and hence keep the proxy access private).

	#rb Martin.Wilson,Lina.Halper

Change 2750077 on 2015/11/02 by Marc.Audy

	Expose UInputComponent::BindAction that supports WithKey delegate signature

Change 2751767 on 2015/11/03 by Thomas.Sarkanen

	Added extra support to Anim Blueprint 'fast-path'

	Added support for negated bools (value gets negated during copy).
	Added support for copying from struct members (via break struct) and split struct pins.

	Removed potentially troublesome references to BP-constructed UProperties, replacing them with the property FName. This adds some extra Initialize() overhead, but prevents various crash-on load issues (one when generating the class CRC). Added guard to prevent multiple initialization to save this more expensive work being done more often.

	Fixup deprecation warnings fallout from multithreaded update changes.

	Fixed up use of AnimInstance in Vicon plugin.
	Fixed up use of AnimInstance in slope warping node.

	Un-deprecated some APIs to become warning free (these APIs are safe to call but just a 'bad idea if you want to do it right').
	Also an extra API to allow for smoother transition: Allow custom allocation/deallocation (including using a proxy member struct) by providing an override point for proxy destruction.

	For XAudio2, because we do our own distance-attenuation calculations, we use the X3dAudio2 API to simply compute a speaker-map for spatialization and force the listener to be at the origin and the emitter to be on the unit-circle. Thus, from XAudio2's perspective, all distances for every listener-emitter pair will be 1.0.

	So in order to use the InnerRadius blending feature, we need to trick it into doing a an inner radius blend relative to a distance of 1.0. For example, if OmniRadius and Distance are the same, then the "NormalizedOmniRadius" is 1.0 and XAudio2 will begin its "blend" of the sound to an omni-directional speaker map.

	If Emitter-listener distance is less than the OmniRadius, we'll want to do more blending to an omni-directional speaker map, but we need to set the InnerRadius to something greater than 1.0 (i.e. so that the normalized distance of 1.0 will be treated as less than the InnerRadius). To do "full" omni-directional blending, the emitter-listener distance will be 0 or close to zero, and the NormalizedOmniRadius will be very large (i.e. close to infiinity).

	The previous math just set the NormalizedOmniRadius to FLT_MAX which is fine but that number is eventually squared before making the API call. FLT_MAX squared is INF.

	Note: I do not think we need to square the OmniRadius in:
	Emitter.InnerRadius = OmniRadius*OmniRadius;
	But I am keeping it t here because of legacy content which depends on that behavior.

	crashfix  was putting bad bodies to sleep at start

	  Fatal error!
	  Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000000
	  UE4Editor-Engine.dll!USkeletalMeshComponent::InitArticulated() [...\\engine\\source\\runtime\\engine\\private\\skeletalmeshcomponentphysics.cpp:875]

	On some skeletalmeshcomponent, some bodies aren't getting created correctly.  Trying to force them to sleep was causing a crash - it expected instantiated physx bodies.  Seems that all the rest of the code is able to tolerate bad bodies.
	Added check to ensure physx body exists before trying to force it to sleep.

	not sure if bad bodies are the norm or if this fix is just more "kicking the can down the road".

	- Fixed crash when building a LOD with SubActors.Num < 2
	- Force HLOD level slider is now always enabled, however won't show complete image if not all HLODs are build
	- LODActor tree view item now scrolls into view if selected in the world
	- Set bAllowCullDistanceVolume to false for LODActor's static mesh components by default
	- Added 7zip files
	- Fixed issue with WinINet complaining about http-request without 'http://' prefix
	- Changed % reduced or original triangles display string, now uses float instead of int (for < 1% reductions)
	- Override texture sizes and automatic texture bias
	- Fixed issue with incorrect material merging, not picking up it required mesh-data during baking. Added extra conditions for rendering with mesh-data.
	- Now incorporate static meshes with opague materials into HLOD merging
	- Fixed issue with incorrect normals after merging meshes who's owning components had been negatively scaled
	- Fixed issue with incorrect texture size being set from MergeActor window (was only changing .X component)
	- Fixed issue with material merging when meshes with multiple LODs are merged, right now only merges LOD0's together if we are also merging the materials (otherwise, merge each LOD)
	- Added ENUM for texture scaling/resizing type that has to be applied while merging the materials
	- Added detail customization class for FMaterialProxySettings

dadb2b42db UE-17938 Adding ability to set a volume headroom per platform to better achieve platform consistency with respect to volume.
- Added stubs per platform in their ini file that doesn't change volume, except for mac which this bug is about and for which I reduced the volume by -6 dB. This can be changed by designers as per needed for their game per platform. The final headroom should be set by designers.
- Removed the hard-coded headroom constant used in OpenAL recently added.
