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

Change 3805828 by Gil.Gribb

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

Change 3806784 by Ben.Marsh

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

Change 3807549 by Graeme.Thornton

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

Change 3807727 by Graeme.Thornton

	Unhide the text asset format experimental editor option

Change 3807746 by Josh.Engebretson

	Remove WER from iOS platform

Change 3807928 by Robert.Manuszewski

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

Change 3808221 by Steve.Robb

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

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

Change 3809233 by Graeme.Thornton

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

Change 3809518 by Ben.Marsh

	Remove the outdated UnrealSync automation script.

Change 3809643 by Steve.Robb

	GitHub #4277 : fix bug; FMath::FormatIntToHumanReadable 3rd comma and negative value

	#jira UE-53037

Change 3809862 by Steve.Robb

	GitHub #3342 : [FRotator.h] Fix to DecompressAxisFromByte to be more efficient and reflect its intent accurately

	#jira UE-42593

Change 3811190 by Graeme.Thornton

	Add support for writing specific log channels to their own files

Change 3811197 by Graeme.Thornton

	Minor updates to output formatting and timing for the text asset commandlet

Change 3811257 by Robert.Manuszewski

	Cluster creation will now be time-sliced

Change 3811565 by Steve.Robb

	Define out non-monolithic module functions.

Change 3812561 by Steve.Robb

	GitHub #3886 : Enable Brace-Initialization for Declaring Variables

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

	#jira UE-48242

Change 3812864 by Steve.Robb

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

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

	#jira UE-53089

Change 3820358 by Ben.Marsh

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


Change 3822594 by Ben.Marsh

	UAT: Improvements to log file handling.

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

Change 3823695 by Ben.Marsh

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

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

Change 3823845 by Ben.Marsh

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

Change 3824180 by Ben.Marsh

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

	#jira

Change 3825777 by Steve.Robb

	Fix to return value of StringToBytes.

Change 3825810 by Ben.Marsh

	UBT: Reduce length of include paths for MSVC toolchain.

Change 3825822 by Robert.Manuszewski

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

Change 3826734 by Ben.Marsh

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

Change 3827730 by Steve.Robb

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

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

Change 3827745 by Steve.Robb

	Initializer list support for TMap.

Change 3827770 by Steve.Robb

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

	#jira UE-53813

Change 3829189 by Ben.Marsh

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

Change 3830444 by Steve.Robb

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

Change 3830718 by Ben.Marsh

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

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

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

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

	#jira UE-53845

Change 3831064 by Ben.Marsh

	Fix log file contention when spawning UBT recursively.

Change 3832654 by Ben.Marsh

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

Change 3832680 by Ben.Marsh

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

Change 3832695 by Ben.Marsh

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

Change 3833528 by Ben.Marsh

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

Change 3833543 by Ben.Marsh

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

Change 3834354 by Robert.Manuszewski

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

	#jira UE-52035

Change 3834400 by Robert.Manuszewski

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

	#jira UE-52035

Change 3834947 by Steve.Robb

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

Change 3835004 by Ben.Marsh

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

Change 3835340 by Ben.Marsh

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

Change 3835972 by Ben.Marsh

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

Change 3836019 by Ben.Marsh

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

Change 3836269 by Ben.Marsh

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

Change 3836543 by Ben.Marsh

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

Change 3836546 by Ben.Marsh

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


Change 3836805 by Ben.Marsh

	Fix commandlet to compile marketplace plugins.

Change 3836829 by Ben.Marsh

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

Change 3837036 by Ben.Marsh

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

Change 3837037 by Ben.Marsh

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

Change 3837040 by Ben.Marsh

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

Change 3837247 by Ben.Marsh

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

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

Change 3837262 by Ben.Marsh

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

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

Change 3837343 by Ben.Marsh

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

Change 3837356 by Ben.Marsh

	Fix invalid character encodings.

Change 3837727 by Graeme.Thornton

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

Change 3837823 by Ben.Marsh

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

Change 3837831 by Graeme.Thornton

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

Change 3837857 by Robert.Manuszewski

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


Change 3837943 by Robert.Manuszewski

	PR #4405: Fix FGarbageCollectionTracer (Contributed by mhutch)


Change 3838451 by Ben.Marsh

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

	#jira UE-53996

Change 3839519 by Ben.Marsh

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

Change 3843790 by Graeme.Thornton

	UnrealPak: Log the size of all encrypted data

Change 3844258 by Ben.Marsh

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

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

	#jira UE-54157

Change 3845796 by Ben.Marsh

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

Change 3845823 by Ben.Marsh

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

	#jira UE-54123

Change 3845901 by Arciel.Rekman

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

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

	(Edigrating 3819174 to Dev-Core)

Change 3846439 by Ben.Marsh

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

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

Change 3816608 by Ben.Marsh

	UBT: Use DirectoryReference objects for all include paths.

Change 3816954 by Ben.Marsh

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

Change 3816986 by Ben.Marsh

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

Change 3816991 by Ben.Marsh

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

Change 3823090 by Ben.Marsh

	UAT: Improve logging for child UAT instances.

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

Change 3826082 by Ben.Marsh

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

Change 3827025 by Ben.Marsh

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

Change 3829927 by James.Hopkin

	Made HTTP interface const correct

Change 3833533 by Ben.Marsh

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

Change 3835826 by Ben.Marsh

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

Change 3835969 by Ben.Marsh

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

Change 3837777 by Steve.Robb

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

Change 3838569 by Steve.Robb

	Algo moved up a folder.

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 3762181 by Joe.Graf

Change 3762607 by Mark.Satterthwaite

	Remove accidentally included changes from 3761995.

Change 3762612 by Mark.Satterthwaite

Change 3763111 by Richard.Wallis

	Clone of CL 3763033 (Release-4.18):
	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

	Giant refactor of global shader interface for upcoming native support of permutation.

	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

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

	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.

	#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.

	Working linear HDR exr output from sequencer

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.

	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.

	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 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.

Change 3794631 by Mark.Satterthwaite

	Missed updating mtlpp's build.cs for TVOS.

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

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

	#jira UE-37553

Change 3697501 by Richard.Wallis

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

	Original Code Review Description:

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

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

Change 3705000 by Chris.Bunner

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

Optimize NV cloth by consuming FVector instead of FVector4 out of the solver. Vertex buffers were using FVector all along. ~15% improvement. Optimize cloth copy to vertex buffer by adding prefetch (similar to how bones are already done). Move local to world cloth transform from CPU to GPU. When simulating lots of vertices game thread was becoming bottleneck doing matrix multiply. Add your TaskGraph task switch latency test code.

Change 3710454 by Mark.Satterthwaite

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

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

Change 3713494 by Richard.Wallis

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

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

	Also tested again repro in linked bug UE-24711.

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

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

Change 3713636 by Mark.Satterthwaite

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

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

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

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

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

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

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

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

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

	Fix merge conflicts

Change 3537059 by Ben.Marsh

	Fixing case of iOS directories, pt1

Change 3537060 by Ben.Marsh

	Fixing case of iOS directories, pt2

Change 3608300 by Chris.Bunner

	Added post process material to preview compile cache set to allow post process volume preview scene improvements.

Change 3608302 by Chris.Bunner

	Fixed decal lifetime fading.

	#jira UE-48400

Change 3608303 by Chris.Bunner

	Updated default WritesAllPixels input to ignore dithering (as intended, was disabled due to isues at the time).
	Fixed material instances returning their local data when not overridden.

	#jira UE-48254

Change 3608455 by Mark.Satterthwaite

	Enabling WorldPositionOffset requires disabling fast-math on Metal because the manually specified FMA's are not respected if one or more arguments is a literal which then leads to very different compiler optimisation between the depth-only shader and the base-pass shader. This change will only affect the way Metal compiles shaders.

	#jira UE-47372

Change 3608462 by Rolando.Caloca

	DR - Cloth vertex buffers no longer generate dummy vertices
	Copy from 3608349 and 3608407

Change 3608491 by Rolando.Caloca

	DR - hlsl - Fix crash when type was not found

Change 3608513 by Rolando.Caloca

	DR - Default to real uniform buffers for Vulkan SM4 & SM5

Change 3608794 by Mark.Satterthwaite

	Implement SV_DepthLessEqual (maybe right?) for Metal - seems to work in the ParallaxOcclusionMapping test map.

	#jira UE-47614

Change 3608929 by Mark.Satterthwaite

	Fix ambiguous expression compile error.

Change 3608991 by Mark.Satterthwaite

	Fix a dumb bug when parsing the Metal compiler version that breaks Metal shader PCH generation on HFS+ volumes.

Change 3609090 by Uriel.Doyon

	StaticMeshComponent and LandscapeComponent now register AO material mask and sky occlusion texture in the texture streamer.
	Changing the current lighting scenario now triggers an update of the texture streamer, and a refresh of lighting data for instanced static meshes.
	Added an option to the "liststreamingtextures" named UNKOWNREF allowing to inspect texture without references in the texture streamer.
	BUILDMATERIALTEXTURESTREAMINGDATA now rebuild every shader in memory and mark for save those with different data.
	MipBias now behaves the same way in shipping than in other builds.
	Fixed texture resolution logic for editor tooltips and in game stats.

Change 3609659 by Richard.Wallis

	Remove Eye Adaption Pixel Shader Workaround for macOS 10.11 (El Cap) Nividia.
	#jira UE-48642

Change 3610552 by Mark.Satterthwaite

	Optimise the constant-propagation pass in hlslcc by using a hash-table to reduce the cost of looking up the existing constant assignment instructions. The get_assignment_entry drops from 25% of runtime to 2.2% of runtime on a 4.2Ghz Quad i7 2017 iMac.

Change 3610662 by Rolando.Caloca

	DR - hlsl - Fix for rwstructured buffer
	Fix for floats printed as ints

Change 3610830 by Michael.Lentine

	ByteAddressBuffer does not have a subtype.

Change 3610869 by Rolando.Caloca

	DR - hlsl - Fix disambiguation between 1.r and 1.0.r

Change 3610982 by Mark.Satterthwaite

	Use the correct code to dump Metal shader text for debugging at runtime.

Change 3610996 by Rolando.Caloca

	DR - hlsl - Actual fix for 0.r

Change 3611312 by Rolando.Caloca

	DR - Integrate: Improve performance of bokeh depth of field.
	* Fewer instances with more work (higher quad count) per instance.
	* Improves performance on RX 480 in the Infiltrator demo by 0.37 ms at 1080p and 0.50 ms at 1440p (average frame time over the beginning of the demo, including the hallway confrontation between the guard and the infiltrator, where heavy DOF is used).
	* Similar optimizations may be possible for other systems that perform similar "instanced draws of quads" (e.g. virtual texture page table updates, lens blur, and velocity scatter).

Change 3611345 by Mark.Satterthwaite

	Missed the hash-table destructor in previous change.

Change 3611372 by Rolando.Caloca

	DR - vk - New barrier/layout api

Change 3611445 by Mark.Satterthwaite

	Fix stupid bugs in MetalBackend's LoadRWBuffer helper function where the wrong type was being used - won't fix problems in the LinearTexture case though.

Change 3611686 by Mark.Satterthwaite

	Remove the sampler from the Metal Linear Texture SRV path as for reasons so far unknown it doesn?╟╓t work with the light grid culling.

	#jira UE-48881

Change 3611743 by Mark.Satterthwaite

	Implement early depth test for Metal - it is implemented such that manual specification of the SV_Depth* outputs will elide the early_fragment_test qualifier as Metal does not permit both at present.

Change 3611746 by Mark.Satterthwaite

	Use early fragment tests implicitly unless we perform a direct resource write or use discard - explicit depth writes always disable early fragment tests as Metal doesn?╟╓t allow both. This should better match D3D driver behaviour.

Change 3611756 by Mark.Satterthwaite

	Missed a header file in last commit.

Change 3611836 by Mark.Satterthwaite

	Fixed the use of Metal?╟╓s capture manager so that it doesn?╟╓t capture more frames than intended.

Change 3611843 by Mark.Satterthwaite

	Tidy up the handling of when to increment the frame count for the Metal capture manager.

Change 3612279 by Michael.Lentine

	Move FP16 Math to Public so that it can be included as part of platform which is where the other float/half defines happen.

Change 3612595 by Rolando.Caloca

	DR - hlslcc - Rebuilt with CL 3611345

Change 3612665 by Rolando.Caloca

	DR - Make cubemap mip barrier consistent with HZB mip barriers

Change 3613124 by zachary.wilson

	Enabling Eye-Adaptation in TM-ShaderModels.

Change 3613205 by Mark.Satterthwaite

	Fully disable linear textures in Metal - they simply aren't performant. Instead we'll have to use helper functions to dynamically type-cast appropriately within the shader. This is currently only configured for a handful of UAV types and will need to be extended.

Change 3613208 by Mark.Satterthwaite

	Add code to MetalBackend to promote half types to float for math operations to avoid compiler errors.

Change 3613354 by zachary.wilson

	Fixing up the Bloom_FFT map. Renaming to fit qa conventions, updating content and improving workflow.

Change 3613409 by Rolando.Caloca

	DR - vk - Layout as part of descriptor writes
	Some access flag warning fixes

Change 3613518 by Daniel.Wright

	Added 'Render Unbuilt Preview Shadows in game' rendering project setting and r.Shadow.UnbuiltPreviewInGame cvar

Change 3613610 by Daniel.Wright

	Volumetric lightmap visualization sphere size is now a fraction of the corresponding brick world size

Change 3613651 by Daniel.Wright

	[Copy] Fixed landscape in the Global Distance field on PS4.  Multiple updates to a vertex buffer using BUF_Dynamic cause a race condition on PS4 with no assert.
	Also added shrinking for GDistanceFieldUploadData which saved 15Mb.

Change 3613696 by Mark.Satterthwaite

	Add the Metal SRV format for Index buffers so that they can be properly type-cast inside the shader. Fixes recompute tangents with latest changes.

Change 3613697 by Rolando.Caloca

	DR - vk - Fix missing layout

Change 3613922 by Rolando.Caloca

	DR - vk - Some fixes for layout/transitions
	- Disable GSupportsDepthFetchDuringDepthTest on desktop as the deferred renderer is not copying the aux depth in the right spot and will be removed

Change 3614009 by Mark.Satterthwaite

	TPS Approved: Integrating the MIT-licensed mtlpp C++ Metal wrapper from Nikolay Aleksiev which will slowly replace previous Metal API wrappers in MetalRHI.

Change 3614015 by Mark.Satterthwaite

	Initial extensions to mtlpp:
	- Fixed over retention of alloc-init'd objects.
	- Added 10_13 & 11_0 availablity macros.
	- Started, but have not yet finished adding new Metal API function wrappers.

Change 3614909 by Rolando.Caloca

	DR - Fix static analysis

Change 3614916 by Michael.Lentine

	Add function to convert FP32 to FP16

Change 3614957 by Mark.Satterthwaite

	mtlpp declarations for macOS 10.13 & iOS 11 Metal features - no matching definitions yet.

Change 3614995 by Mark.Satterthwaite

	Revert all changes to project config's from Rhino that should not have come back to Dev-Rendering, keeping only the solitary change to Metal shader standard necessary for ShowdownDemo.

Change 3615035 by Rolando.Caloca

	DR - Generate mips using shader for HZB

Change 3615561 by Rolando.Caloca

	DR - Fix deprecation warning

Change 3615787 by Mark.Satterthwaite

	Only emit min. OS version specification into the Metal shader bytecode for macOS as we share shaders between iOS & tvOS and this option inhibts that.

	#jira UE-48919

Change 3616317 by Mark.Satterthwaite

	Make TonemapperConfBitmaskPC  the proper size so we dn't attempt to access uninitialized memory.

Change 3616357 by Mark.Satterthwaite

	And fix some compile errors...

Change 3616473 by Rolando.Caloca

	DR - Render pass api minor changes

Change 3616518 by Mark.Satterthwaite

	#jira UE-48472

Change 3616706 by Rolando.Caloca

	DR - Vulkan fixes (integration from Vulkan working branch)
	- Fix for editor outline
	- Fix for profilegpu

Change 3616770 by Rolando.Caloca

	DR - vk - Mark GIsGPUCrashed on device lost

Change 3616993 by Daniel.Wright

	IndirectLightingCacheQuality respects VolumetricLightingMethod

Change 3616996 by Daniel.Wright

	Volumetric Lightmap show flag is respected by Volumetric Fog

Change 3616999 by Daniel.Wright

	Fixed ObjectRadius in Volume domain materials

Change 3617777 by Rolando.Caloca

	DR - Fix static analysis warning

Change 3617863 by Guillaume.Abadie

	PR #3875: Removed Duplicated "RHI" Module Dependency (Contributed by DavidNSilva)

	#jira UE-48159

Change 3618133 by Rolando.Caloca

	DR - vk - Set general layout for compute shader resources
	- Assume transitions to writable imply end render pass

Change 3618292 by Michael.Lentine

	Add support for Expressions, Jump Statments, and Structs.

Change 3618326 by Rolando.Caloca

	DR - vk - Fix transition flags

Change 3618408 by Daniel.Wright

	Lightmass skylight solver improvements
	* Lightmass uses a filtered cubemap to represent the skylight instead of a 3rd order Spherical Harmonic.  Directionality in shadowed areas is improved.  Mip level is chosen based on the ray differential for anti-aliasing.
	* Multiple skylight and emissive bounces are now supported with a radiosity solver, controlled by NumSkyLightingBounces in Lightmass WorldSettings.  More bounces results in longer build times, and the radiosity time is not distributable.
	* The mapping surface cache is now rasterized with supersampling, reduces incorrect darkness in corners
	* Combined direct lighting, photon irradiance, skylight radiosity and diffuse in the mapping surface cache so final gather rays only have to do one memory fetch, speeds up lighting builds by 7%.
	* Added support for Embree packet tracing although no solver algorithms use it yet

Change 3618413 by Daniel.Wright

	Swarm hands out the most expensive tasks in roughly a round robin ordering among distribution agents.  Lightmass processing of a single task is multithreaded, so ideally the most expensive tasks are evenly distributed among active agents.  This has the biggest impact in small scenes with 10's of high resolution lightmaps, and with a distribution farm.  Build time in one scene went from to 113s -> 47s.

Change 3618439 by Mark.Satterthwaite

	Fix the assert in hlslcc when we have saturate(int) and the shader language spec. supports a native saturate intrinsic.

Change 3618468 by Rolando.Caloca

	DR - vk - Fix copy to non render target surface

Change 3618696 by Daniel.Wright

	Worked around Lightmass crash callstacks not getting reported back to the editor

	Added files to cross-build glslang on Windows.

	(Edigrating //UE4/Main/...@3621127 to //UE4/Dev-Rendering/...)

Change 3621194 by Rolando.Caloca

	DR - glslang - Update to 1.0.57.0
	- Fix some tab/whitespace mismatch

Change 3621225 by Rolando.Caloca

	DR - Revert glslang (Back out changelist 3621194)

Change 3621254 by Mark.Satterthwaite

	Duplicate 3610656 and revert the incorrect merge from the Rhino task stream. Fixes EyeAdaptation on all clang platforms properly thanks to RCL.

Change 3621261 by Mark.Satterthwaite

	Trivial FMetalStateCache optimisations - won't help much but equally they shouldn't hurt.

Change 3621262 by Mark.Satterthwaite

	Correct the handling of MSAA target in Desktop Forward for iOS - now the problem is that iOS always creates an internal resolve target so which texture to bind depends on the shader parameter type. Not sure (yet) how best to solve that.

Change 3621263 by Mark.Satterthwaite

	Don't mandate Mobile Metal for projects that have Metal MRT enabled.

Change 3621301 by Rolando.Caloca

	DR - Unity build fix

Change 3621349 by Mark.Satterthwaite

	Fix a bug in MetalBackend that was omitting the depth-output variable from the hlslcc signature if the semantic was SV_DepthLessEqual rather than SV_Depth.

Change 3621546 by Uriel.Doyon

	Refactor of the texture 2D mip update logic to offload more work on the async thread.
	#jira UE-45332
	#jira UE-45789

Change 3622210 by Rolando.Caloca

	DR - Do not store DDC data if static mesh failed to build
	#jira UE-48358

Change 3622349 by Arciel.Rekman

	Better build script for Linux glslang and a bugfix.

	- Support for r.Vulkan.ProfileCmdBuffers

Change 3622506 by Rolando.Caloca

	DR - vk - Back out changelist 3622401

Change 3622521 by Mark.Satterthwaite

Change 3622910 by Rolando.Caloca

	DR - static analysis fix

Change 3622964 by Mark.Satterthwaite

	Fix generation of .metallib on local Macs and exclude .metallib files from the pak - they must always be loaded from disk.

	#jira UE-48193

Change 3622986 by Mark.Satterthwaite

	A couple more trivial optimisations to MetalRHI for iOS:
	- Metal page size is 4k but only buffers under 512 bytes should go through set*Bytes on iOS to balance CPU cost.
	- On iOS the minimum buffer size should therefore be 1k and on Mac 4k as nothing else makes much sense.
	- No need to rebind uniform buffers if to the same slot - it just wastes cycles.

Change 3623266 by Rolando.Caloca

	DR - Fix GL4 rendering

	#jira UE-49187

Change 3623377 by Daniel.Wright

	Fix a LPV race condtion due to parallel RSM draw-call submission
	#jira UE-48247

Change 3626015 by Jian.Ru

	Small fix to 3625983

Change 3626294 by Michael.Trepka

	Copy of CL 3535792 and 3576637

	Added support for changing monitor's display mode on Mac in fullscreen mode. This greatly improves performance on Retina screens when playing in resolutions lower than native.

	Fixed a problem with incorrect viewport size being set in windowed fullscreen in some cases. Also, slightly improved screen fades for fullscreen mode transitions on Mac.

	#jira UE-48018

Change 3626532 by Marcus.Wassmer

	Fix divide by 0 crash when GPU timing frequency not available for whatever reason.

Change 3626548 by Ryan.Brucks

	Fix Metal 2.0 compilation.

Change 3626997 by Rolando.Caloca

	DR - vk - cis fix
	- Initial RGBA16 readback

Change 3627016 by Mark.Satterthwaite

	Workaround more of Metal's unfortunate tendency to re-associate float mul/add/sub operations - this time from Metal's own standard-library.

Change 3627040 by Brian.Karis

	Removed old rasterized deferred reflection env path.
	Removed reflection compute shader. Replaced with PS. Small perf gain.

Change 3627055 by Mark.Satterthwaite

	No MSAA support on Intel Metal or iOS Desktop Forward for the moment as neitehr work and I don't want to have lots of crashes out in the wild until we have a solution.

Change 3627057 by Mark.Satterthwaite

	Make SCW's directcompile not fall over with Metal when there are compilation errors.

Change 3627083 by Mark.Satterthwaite

	Invalidate Metal shaders so QA testing picks up the most recent changes.

Change 3627788 by Chris.Bunner

	[Duplicate, CL 3627751] - VisibleExpressions static switch value evaluation needs to handle reroute nodes rather than only verify first expression.

Change 3627834 by Rolando.Caloca

	DR - cis fix

Change 3627847 by Rolando.Caloca

	DR - 4th try to fix static analysis

	Merge fixes.

Change 3628597 by Chris.Bunner

	Merge fixes.

Change 3628656 by Michael.Trepka

	One more workaround for a bug in StandardPlatformString.cpp. It doesn't handle %lf format correctly, parsing it as long double instead of ignoring the 'l' format sub-specifier.

Change 3628685 by Daniel.Wright

	CPU interpolation of Volumetric Lightmaps for the mobile renderer.  They use a scene cache based on interpolation position, since the precomputed lighting buffer for movable objects is recreated every frame.

Change 3629094 by Ryan.Brucks

	Fixes to RenderTargetCreateStaticTexture2DEditorOnly with additional error checks

	#RB none

Change 3629223 by Rolando.Caloca

	3617483

Change 3629770 by Mark.Satterthwaite

	Fix a mobile Metal shader compilation error when using the FMA workaround for "cross" which should only be applied if the min. Metal version is 1.2 (as FMA is not known to work prior to this).

Change 3629793 by Daniel.Wright

	Fixed VolumetricLightmapDetailCellSize not being respected in small levels, causing too much volumetric lightmap density and memory

Change 3629859 by Mark.Satterthwaite

	macOS 10.12 also had problems with MSAA in forward rendering - so only permit it to work on macOS 10.13 and above.

Change 3630790 by Mark.Satterthwaite

	Move RHISupportsMSAA so that the Metal related complications for when it is viable can be hidden within.

Change 3630990 by Rolando.Caloca

	DR - vk - Redid CL 3617437 (optimize number of Buffer Views, eg 165 to 58)

Change 3631071 by Mark.Satterthwaite

	Fix a small gotcha in a change from Dev-Mobile: for MetalRHI we need to explicitly configure the ShaderCacheContext for the immediate/device context after initialising the shader-cache.
	#jira UE-49431

Change 3631076 by Rolando.Caloca

	DR - vk - Redo 3617574, reduce number of render pass objects created

Change 3631250 by Mark.Satterthwaite

	Make another Metal warning a Verbose log instead as it isn't interesting unless you are me.

Change 3631911 by Chris.Bunner

	Back out changelist 3628035.

	#jira UE-49364, UE-49365

Change 3632041 by Mark.Satterthwaite

	Fix cloth rendering on Metal - some of the data in FClothVertex is uint but we load it from a float buffer. This could be due to a bug in Metal's as_type<uint4>() or it could be that Xcode 9's compiler is now finally enforcing Metal's official flush-to-zero-on-load semantics for denorms - it isn't immediately obvious.

	#jira UE-49439

Change 3632261 by Brian.Karis

	SM4 fallback for reflection captures.

Change 3632281 by Mark.Satterthwaite

	Fix an intermittent assert on startup when the AVFoundation movie player gets the QAGame TM-ShaderModels video ready to play prior to the rendering thread being back online when resizing the window. This is done by deferring the processing of AVFoundation events to the game-thread where it won't cause a threading violation.

Change 3632382 by Rolando.Caloca

	DR - vk - Fix clang warning

Change 3633338 by Chris.Bunner

	Static analysis/Linux compile fix.

	#jira UE-49502

Change 3633616 by Jian.Ru

	Force alpha to 0xff for functional UI screenshot tests
	#jira UE-48266

Change 3633818 by Daniel.Wright

	Better indirection texture clamping and asserts

Change 3634319 by Mark.Satterthwaite

	Stop FVolumetricLightmapDataLayer ::Discard which is invoked by the Editor RHI during texture-upload from chucking the backing data when in the Editor - because if we do that then cooking will serialise an empty array. This was only apparent on Mac because Metal always invokes Discard on BulkDataInterfaces and D3D11 never does.

	#jira UE-49381

Change 3634613 by Rolando.Caloca

	DR - Call discard on bulk data for textures

	#jira UE-49533

Change 3634654 by Mark.Satterthwaite

	Fixes for broken iOS builds:
	- Fix RHIGetShaderLanguageVersion returning the wrong version for iOS Metal if the Mac version had already been queried - this has been wrong for a long while.
	- Remove the precise:: qualifier for Metal's fma intrinsic - it isn't necessary and breaks on older OSes.

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

Change 3441680 by Uriel.Doyon

	Added units to point light intensity, to allow the user to specify the value in candelas or lumens.
	New point light actors now configure the intensity in candelas by default.
	Replaced viewport exposure settings by an EV100 slider.
	Hidding the tone mapper in the show flag now still applies the exposure.
	Added a new AutoExposure method called EV100 which allows to specify :
	- MinEV100, MaxEV100
	- Calibration Constnat
	- Exposure Compensation
	#jira UE-42783

Change 3512288 by Rolando.Caloca

	DR - Fix issue when recycling image handles

Change 3512338 by Michael.Lentine

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

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

	#jira UE-46137

Change 3513112 by Richard.Wallis

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

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

	#jira UE-45657

Change 3517039 by Yujiang.Wang

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

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

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

	#jira UE-33982

Change 3517069 by Yujiang.Wang

	Fix for ScissorRect settings in d3d11 being lost under certain scenarios

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

	#jira UE-45465 UE-44760

	DR - Fix linking issue

Change 3525459 by Daniel.Wright

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

Change 3525461 by Daniel.Wright

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

Change 3590961 by Mark.Satterthwaite

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

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

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

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

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

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.

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

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

	- Disable hardware acceleration on Windows, since this causes severe performance issues with video rendering
	Please note: To actually see 60fps video, you need to ensure the browser frame rate passed into FWebBrowserSingleton::CreateBrowserWindow is set to 60 (default is 24)

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

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

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

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

Change 2963214 on 2016/05/02 by Ben.Marsh

	BuildGraph: Allow specifying optional dependencies for a node, indicating that the build products from an upstream node are desired, but should not block the node from running.

Change 2972295 on 2016/05/10 by Ben.Marsh

	EC: Remove spacing in notification emails to reduce size, and help prevent gmail from truncating messages. Also allow mailing notification emails when doing a dry run, and reading stream settings from another branch.

	EC: Store properties for the last succeeded builds, including the list of users that were notified about it.

Change 2976390 on 2016/05/12 by Ben.Marsh

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

Change 2733540 on 2015/10/19 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream

	Capsule shadows
	* Capsule shadows excel at extremely soft area shadows caused by a large light source angle, but don't support accurate self-shadowing
	* Artists can setup a physics asset containing Spheres and Sphyls (capsules) for a skeletal mesh that will be used to represent the mesh's occlusion
	* These shapes can then be used for direct shadowing (bCastCapsuleDirectShadow) on a skeletal mesh component, whose softness depends on the light source angle / radius
	* The shapes can also be used to create an indirect shadow (bCastCapsuleIndirectShadow), whose direction and softness is derived from the precomputed sky occlusion (stationary sky light) or primary indirect lighting (static sky light)
	* Capsule shadowing is computed at half res and uses tiled deferred culling for efficiency - only implemented for PC SM5 + PS4 so far
	* Shadowing of movable skylights is not yet supported

Change 2735460 on 2015/10/20 by Uriel.Doyon@uriel.doyon_office_data

	Basepass drawlist are now merged within a single drawlist.
	Lighting policy parameters are now accessed through a uniform buffer.
	Changed the global resource initialization so that InitRHI now comes before InitDynamicRHI
	#codereview nick.penwarden

Change 2744741 on 2015/10/28 by Nick.Penwarden@nickp_streams

	Remove unused RHI methods:

	RHIIsDrawingViewport
	RHIGpuTimeBegin
	RHIGpuTimeEnd

	Made default/empty versions of these calls and removed stubs from RHIs that don't use them:

	RHISuspendRendering
	RHIResumeRendering
	RHIIsRenderingSuspended

Change 2745714 on 2015/10/28 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream

	Lighting channels - each component and light can choose from 3 channels
	* Primitives output their channel mask to stencil during the base pass, the masks are copied to a texture after the base pass, deferred lighting passes compare the primitive mask against the light's mask
	* Dynamic shadow casting also respects the channels
	* Only works on opaque materials, direct lighting, dynamic lighting
	* Not implemented for tiled deferred atm
	* This will replace CastsShadowsFromCinematicObjectsOnly in the future
	#rb Martin.Mittring

Change 2746243 on 2015/10/29 by Marcus.Wassmer@Marcus.Wassmer_DevRendering_New

	First pass at separate Async Compute Context
	#codereview Lee.Clark,Daniel.Wright
	#rb Gil.Gribb

Change 2746989 on 2015/10/29 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering

	Removed a lot of complexity of the skeletal mesh motionblur code (better for multithreading, simpler, faster) but going from one large buffer to per mesh buffers. Upload of bones only needed once.

	* GPUSkinCache didn't even work before (in this branch)
	* tested  BasePass velocity
	* tested split screen
	* tested editor pause
	* matinee camera cut (no need, invalidates velocity)
	* tested CPU Skin?  (never has motionblur)
	* tested CreateSceneProxy (recreation is prevented in CreteSceneProxy unless bone count changes)
	* test ES2 -featureleveles2

	#rb: Rolando.Caloca

Change 2750734 on 2015/11/02 by Uriel.Doyon@uriel.doyon_office_data

	Embree integration into Lightmass
	Can be enabled through Lightmass.ini  [DevOptions.StaticLighting]bUseEmbree.
	Also [DevOptions.StaticLighting]bVerifyEmbree will compare ray casting results.
	Only usable on Win64 with this submit.
	#review daniel.wright

Change 2752730 on 2015/11/03 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering

	added SSAO CS version, can be enabled with

	r.AmbientOcclusion.Compute 1

	Not optimized yet
	#rb:Olaf.Piesche

Change 2752766 on 2015/11/03 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream

	Lightmass solver quality improvements
	* IndirectLightingScale is no longer applied to photons, avoids splotchy artifacts when using small scales
	* New 'Lightmass Portal' actor / component which tells the solver where to look for significant lighting.  When lighting with a Static Skylight only, in a mostly indoor environment, setting up these portals is the only way to get high quality.
	* Skylight bounce lighting is now much more accurate and leverages adaptive sampling
	* Fixed a bug that effectively disabled adaptive sampling on high IndirectLightingQualities
	* Shadow penumbras are also improved by IndirectLightingQuality
	* Texel debugging is now a cvar 'r.TexelDebugging', instead of requiring a full recompile

Change 2754018 on 2015/11/04 by Uriel.Doyon@uriel.doyon_office_data

	Quad Complexity ViewMode (PCD3D_SM5 only).
	Shader Complexity with Quad Overhead ViewMode (PCD3D_SM5 only). Require ShaderComplexity ViewMode & Show.Visualize.QuadOverhead
	#review brian.karis

Change 2754760 on 2015/11/04 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering

	improved SSAO quality (less high frequency noise) to avoid TemporalAA smearing

Change 2756308 on 2015/11/05 by Rolando.Caloca@rolando.caloca_T3903_S

	DevRendering - Enable removing unused outputs on PS4 shader pipelines, disable by default removing unused on D3D (toggable with r.D3DRemoveUnusedInterpolators)
	#codereview Marcus.Wassmer

Change 2757063 on 2015/11/06 by Simon.Tovey@Simon.Tovey_Dev

	Submitting pull request from user Pierdek.
	Early out of particle collision module update if there are no active particles.

	#github
	#1614

Change 2757340 on 2015/11/06 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering

	UE4 - Fixed the experimental r.RHICmdBalanceParallelLists 2 mode and renabled it for orion.

Change 2757343 on 2015/11/06 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering

	UE4 - Added a path so that texture streaming can avoid flushing the RHI thread.

Change 2757985 on 2015/11/06 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream

	Added new PrimitiveComponent setting bSingleSampleShadowFromStationaryLights
	* When enabled, shadowing of a movable component from a stationary directional light will come from the Volume Lighting Samples precomputed by Lightmass
	* This provides essentially free on/off shadow receiving on dynamic objects, with a fade over time between states
	* Lighting has to be rebuilt once for this to work
	#rb Rolando.Caloca

Change 2759058 on 2015/11/09 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering

	UE4 - Dynamically set stream source to avoid creating a separate drawing policy for each static mesh with vertex colors.
	#rb Daniel.Wright

Change 2760523 on 2015/11/10 by Uriel.Doyon@uriel.doyon_office_data

	Enabled Embree by default

0a2357f472 Added PrecomputedAOMask material node - allows procedural texturing using Ambient Occlusion computed by Lightmass
* bGenerateAmbientOcclusionMaterialMask must be enabled in WorldSettings for the mask to be produced by a lighting build.  The mask is stored in a BC4 texure which adds half a byte per lightmap texel.
