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

Change 3873906 by Dan.Oconnor

	Revised fix for preventing delegate functions from appearing in context menu when using the compilation manager - needed to run after CallDelegateHandler changed statement type

	#jira UE-51726

Change 3873614 by Dan.Oconnor

Change 3872238 by Mark.Satterthwaite

	Duplicate CL #3871025
	Make Manual Vertex Fetch a property of the shader platform for Metal - only the desktop platforms (METAL SM5/SM5_NoTess/MRT) will use manual vertex fetch. The mobile platforms use vertex descriptors. Prevents problems with cooked versions of games not working properly on Metal due to a mismatch between the runtime's Manual-Vertex-Fetch state versus the state used by the cooker when compiling shaders.

	#jira UE-54843

Change 3870283 by Arne.Schober

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

	#jira none

	glTF: binary format's BIN chunk is not necessarily right after the JSON chunk.

	Discussed this with glTF spec authors. See https://github.com/KhronosGroup/glTF/issues/1177

	glTF: base64 decoding of data buffers and images

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

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

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

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

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

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

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

Change 3726554 by Luke.Thatcher

	[CONSOLE] [+] Improved Scoped Named Events
	 - Added SCOPED_NAMED_EVENT(_FSTRING/_TEXT/_F) macros to allow use of string literals, FString and printf in scoped named event strings.
	 - Replaced explicit use of FPlatformMisc::Begin/EndNamedEvent throughout the engine with macros, so the events can be compiled out.
	 - Fixed performance issues on various platforms with named events. SCOPED_NAMED_EVENT macros were not considering whether the platform uses wide or ansi char strings.

	Duplicate from FN CL 3712515
	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 3813513 by Ben.Woodhouse

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

Change 3814039 by Ben.Woodhouse

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

Change 3814041 by Ben.Woodhouse

	Integrate as edit CL 3796390 from Fortnite/Main:

	Fix CsvProfiler not compiling in shipping for now

Change 3814229 by Ben.Woodhouse

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

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

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

Change 3814242 by Ben.Woodhouse

	Disable CSV unit stats on the dedicated server

Change 3817339 by Ben.Woodhouse

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

Change 3817582 by Ben.Woodhouse

	Fix android compile warning

Change 3823242 by Ben.Woodhouse

	Integrate as edit from Fortnite/Main 3820067:

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

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

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

Change 3823840 by Ben.Woodhouse

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

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

	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

	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.

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.

	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

	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.

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.

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

Change 3658809 by Chris.Bunner

Change 3697488 by Richard.Wallis

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

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

	#jira UE-37553

Change 3697501 by Richard.Wallis

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

	Original Code Review Description:

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

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

Change 3700356 by Guillaume.Abadie

	Implements secondary screen percentage to be able to do TAA upsample followed spatial upscale so that the editor viewport still have same TAA upsample screen percentage range to test the content with no matter monitor's DPI.

Change 3701105 by Guillaume.Abadie

	Ignore per view automatic mip bias on texture type other than 2d textures.

	#jira UE-51396

Change 3702297 by Richard.Wallis

	Mac compile fix for nullable specifier.  Looks like Obj class using the C++ class also needs this otherwise it throws.  Seems to be some kind of xcode/compiler caching bug with this stuff as it'll report the error once then on subsequent compiles say everything is ok.

	#jira UE-51386

Change 3702357 by Richard.Wallis

	Mac nullability compile fix - again.  Looks like I fell foul of that xcode compile caching!

	DR - Debug label on D3D11 UAVs
	- Validate when running -d3debug

Change 3705000 by Chris.Bunner

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

Change 3706065 by Guillaume.Abadie

	Does some renaming for primary screen percentage, and move the primary screen percentage method selection from dynamic resolution driver to FSceneView.

Change 3706464 by Chris.Bunner

	Fixed material property translate overrides that were generating code in the wrong entry.
	Fixed conditions  in If material expression GetInputType and IsMA check.

	#jira UE-51368

Change 3706641 by Chris.Bunner

	Missing "break" in switch statement (which unfortunately needs another bump to resolve).

Change 3706642 by Guillaume.Abadie

	Fixes assertion failure when r.TemporalAA.EnableUpscale = 1

Change 3706650 by Gil.Gribb

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

Change 3710454 by Mark.Satterthwaite

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

Change 3710456 by Mark.Satterthwaite

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

Change 3710457 by Mark.Satterthwaite

	DX11 texture formats for Mac Metal please!

Change 3710480 by Mark.Satterthwaite

	Permit RHI thread and parallel execution in Mac -game mode again.

Change 3710522 by Mark.Satterthwaite

	MSVC type-mismatch error fixes.

Change 3710580 by Mark.Satterthwaite

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

Change 3710616 by Mark.Satterthwaite

	Missing file.

Change 3712972 by Guillaume.Abadie

	Fixes Circle DOF's negative alpha channel getting clamped to 0 in TAA pass.

Change 3712979 by Guillaume.Abadie

	Fixes wrong RT reallocation when doing TAA upsample in editor viewports with secondary upscale.

Change 3713406 by Mark.Satterthwaite

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

Change 3713494 by Richard.Wallis

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

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

	Also tested again repro in linked bug UE-24711.

	#jira UE-40533

Change 3713612 by Mark.Satterthwaite

	Integrate LPV_STORE_INDEX_IN_HEAD_BUFFER related changes from //depot/Partners/Microsoft/UE4-MS/Engine-Fable @ 2954744

	This should make Light Propagation Volumes potentially viable on non-Microsoft platforms.

Change 3713623 by Mark.Satterthwaite

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

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

Change 3713636 by Mark.Satterthwaite

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

Change 3714049 by Guillaume.Abadie

	Do not set screen percentage method to TAA upsample when anti aliasing method is not TAA even if there is automatic fallback in the renderer.

Change 3714306 by Guillaume.Abadie

	Fixes assertion failure in dynamic resolution state proxy with GPU busy time queries.

Change 3714714 by Mark.Satterthwaite

	Tweak Metal GPU identification so that it works with eGPU boxes and protoype hardware - these changes only apply to macOS 10.13 so the system as a whole remains.

Change 3716104 by Mark.Satterthwaite

	Fix 10.12/Xcode 8 compile errors from the build-farm which is still split until Fortnite can update.

Change 3716120 by Mark.Satterthwaite

	Silence static-analysis.

Change 3716158 by Guillaume.Abadie

	Rewrites editor primitive compositing to support TAA upsample.

	This takes the oportunity to remove the manual depth testing in base pass pixel shader of editor primitives.

Change 3716271 by Daniel.Wright

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

Change 3716434 by Mark.Satterthwaite

	Backout the remaining change from 3632041 that is no longer necessary - this was the last of the 4.18 Metal workarounds.

	#jira UE-51580

Change 3717111 by Arne.Schober

	Fixing nomalization of Morph Tangents https://udn.unrealengine.com/questions/392462/
	Also implemanted batching of the dispatches which should help worst case perfomance where dispatches become too small.
	CalculateInverseAccumulatedWeights is not cheap and proably should be moved onto a task thread that runs as soon as the input weights are ready.

Change 3717127 by Mark.Satterthwaite

	Fix a mismerge from the reversion of 3632041 - part of the modified code had been moved into another file and I didn't initially notice.

Change 3717178 by Mark.Satterthwaite

	Remove useless copy-pasted expressions from glsl_type::GetByteAddressBufferInstance & force MetalBackend to relink. Apparently the previous Mac libs were mysteriously broken.

	#jira UE-51583

Change 3717476 by Marcus.Wassmer

	Fix PS4 compile.  funciton local statics not allowed on PSSL
	Also enabled the new atomics method for LPVs for all platforms

Change 3717502 by Arne.Schober

	DR - Compiletime option for compressed ruleset (0.02ms perf gain on PS4 and disabled by default as it limits array size to 2million entries)

Change 3717601 by Arne.Schober

	DR - Move cycle counter into more meaningfull locations.

Change 3718054 by Guillaume.Abadie

	Removes unecessary check() failure on secondary upscale that fires when testing raw output screen percentage method.

Change 3718066 by Guillaume.Abadie

	Reland: Rewrites editor primitive compositing to support TAA upsample.

	This takes the oportunity to remove the manual depth testing in base pass pixel shader of editor primitives.

Change 3718589 by Mark.Satterthwaite

	Console-variable to enable and disable Manual-Vertex-Fetch for Metal and fix the internal code to handle the subtle changes in behaviour for vertex-declarations so we don't explode under the Metal validation layer. MVF works on macOS, though testing did expose an error with Tessellation on Nvidia (true for MVF enabled & disabled).

Change 3718633 by Guillaume.Abadie

	Fixes temporal instability issue of TAA upsample with secondary screen percentage.

Change 3718658 by Arne.Schober

	DR - 25% MorphTarget Speed increase because there was a bit of cache thrashing between the waves going on.

	Extend mtlpp compiler testing app to support Metal tessellation compute shaders so we can send Nvidia a much simpler reproduction of their regression.

Change 3720099 by Mark.Satterthwaite

	Make the left-hand arguments work in airdiff.

Change 3720413 by Mark.Satterthwaite

	Support standalone compute shaders in the mtlpp compiler test app.

Change 3721232 by Mark.Satterthwaite

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

Change 3721244 by Mark.Satterthwaite

	Fix incorrect enum handling for Metal features due to overflow.

	#jira UE-51643

Change 3722682 by Guillaume.Abadie

	Fixes wrong clear color in SSR important for VR that has a HMD mesh.

Change 3722766 by Rolando.Caloca

	DR - Fix static analysis

Change 3722943 by Mark.Satterthwaite

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

Change 3723100 by Mark.Satterthwaite

	Apparently users like enabling Metal shader standards that won't work on their current OS, so don't display those that aren't going to work & display an error message before quitting rather than crashing when trying to load a project that tries to use an incompatible shader version.

Change 3723121 by Mark.Satterthwaite

	Fix build error.

Change 3723245 by Daniel.Wright

	Ensure for when a reflection capture upload fails due to incorrect lighting scenario level handling

Change 3725555 by Chris.Bunner

	[Dupliate] CL 3725548 - Fixed invalid screenpercentage value in VehicleGame sample (was setting -1 but should default to 100). This has always been broken but was recently exposed by CL 3686200.

Change 3726845 by Guillaume.Abadie

	Exposes SvPosition to material through screen position material expression, so that material no longer have SvPosition * InvViewSize * ViewSize precision loss.

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

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

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

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

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

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

Change 3358367 by tim.gautier

	Submitting resaved QAGame assets - Materials, Material Instances, Material Functions and Parameters

Change 3624848 by Jamie.Dale

	Added a composite font for the editor (and Slate core)

	This is defined in FLegacySlateFontInfoCache::GetDefaultFont and uses our default Roboto fonts (and the culture specific fallback fonts), and is now used as the default font for Slate and the editor.

	This change removes all the manual TTF/OTF file references from the various Slate styles, as well as updating 200+ hard-coded font references to use the new default font.

	This fixes various rendering issues with fonts in the editor when using different languages, and clears a big barrier for removing the legacy localized fallback font support.


Change 3654993 by Jamie.Dale

	'Native' (now called 'FNativeFuncPtr') is now a function pointer that takes a UObject* context, rather than a UObject member function pointer

	This avoids ambiguity when binding a native function pointer to a type that doesn't match the context pointer, as you could end up getting a function called with an incorrect 'this' pointer

	Breaking changes:
	 - Native has been renamed to FNativeFuncPtr.
	 - The signature of a native function has changed (use the DECLARE_FUNCTION and DEFINE_FUNCTION macro pair).
	 - Use P_THIS if you were previously using the 'this' pointer in your native function.

Change 3699591 by Jamie.Dale

	Added support for displaying and editing numbers in a culture correct way

	Numeric input boxes in Slate will now display and accept numbers using the culture correct decimal separators. This is enabled by default, and can be disabled by setting "ShouldUseLocalizedNumericInput" to "False" in XEditorSettings.ini (for the editor), or XGameUserSettings.ini (for a game).

	#jira UE-4028


Change 3719568 by Jamie.Dale

	Allow platforms to override the default ICU timezone calculation


Change 3622366 by Bradut.Palas

	#jira UE-46677

	Don't allow OnLevelRemovedFromWorld to reset the transaction buffer if we're in PIE mode.
	Also, remove one undo barrier in case the event was triggered in PIE mode or else we block the user from undoing previous actions.

Change 3622378 by Bradut.Palas

	#jira UE-46590

	we have a general bug with detecting the size of the last column, but the clamping prevents it from appearing with the other resize modes. The Content Browser is the only one to use fixed width.
	The bug is that the size of the last element is incorrectly reported, after we drag back and forth.
	Fixed by not reading the size real time, but reading it from the SlotInfo structure that is created earlier, which holds the correct value.

Change 3622552 by Jamie.Dale

	Added support for per-culture sub-fonts within a composite font

	This allows you to do things like create a Japanese specific Han sub-font to override the Han characters used in a CJK font (previously you needed to create a localized font asset to achieve this).

Change 3623170 by Jamie.Dale

	Fixing warning

Change 3624846 by Jamie.Dale

	Composite font cache optimizations

	- Converted a typically small sized map to a sorted array + binary search.
	- Converted the already sorted range array to use binary search.
	- Contiguous ranges using the same typeface are now merged in the cache.

Change 3625576 by Cody.Albert

	We now only set the widget tree to transient instead of passing the flag through StaticDuplicateObject. This was causing instanced subobjects to be flagged with RF_DuplicateTransient, preventing them from properly being duplicated when an array of instanced subobjects was modified.

	#jira UE-47971

Change 3626057 by Matt.Kuhlenschmidt

	Expose EUmgSequencePlayMode to blueprints

	#jira UE-49255

Change 3626556 by Matt.Kuhlenschmidt

	Fix window size and position adjustment not accounting for primary monitor not being a high DPI monitor when a secondary monitor is.  Causes flickering and incorrect window positioning.

Change 3631140 by Arciel.Rekman

	OpenAL: update Linux version to 1.18.1 (UETOOL-1253)

	- Also remove a hack for RPATH and make it use a generic RPATH mechanism.
	- Bulk of the change from Cengiz.Terzibas

	#jira UETOOL-1253

Change 3632924 by Jamie.Dale

	Added support for a catch-all fallback font within composite fonts

Change 3633055 by Jamie.Dale

	Fixed some refresh issues in the font editor

Change 3633062 by Jamie.Dale

	Fixed localization commands being reported as unknown

Change 3633906 by Nick.Darnell

	UMG - You can now store refrences to widgets in the same UserWidget.  If you need to create links between widgets this is valuable.  Will likely introduce new ways to utilize this in the future, for now just getting it working.

Change 3634070 by Arciel.Rekman

	Display actually used values of material overrides.

Change 3634254 by Arciel.Rekman

Change 3636706 by Lauren.Ridge

	Epic Friday: Save parameters to child or sibling  instance functionality

Change 3638706 by Jamie.Dale

	Added an improved Japanese font to the editor

	This is only used when displaying Japanese text when the editor is set to Japanese, and uses a font with Japanese-style unified Han characters (our default fallback font uses Chinese-style unified Han characters).

	#jira UE-33268

Change 3639438 by Arciel.Rekman

	Linux: Repaired ARM server build (UE-49635).

	- Made Steam* plugins compile.
	- Disabled OpenEXR as the libs aren't compiled (need to be done separately).

	(Edigrating CL 3639429 from Release-4.17 to Dev-Editor)

Change 3640626 by Matt.Kuhlenschmidt

	PR #4011: Remove space from filename (Contributed by projectgheist)


Change 3640697 by Matt.Kuhlenschmidt

	PR #4010: PNG alpha fix (Contributed by mmdanggg2)


Change 3641137 by Jamie.Dale

	Fixed an issue where a culture specific sub-font could produce incorrect measurements during a culture switch

	It would fallback to the last resort font for a frame or two while the font cache flushed. This has it update the ranges immediately.

	- Old workaround should no longer be needed, while this dependency makes UE4 depend on a ton of external libs.

Change 3728524 by Michael.Trepka

	Copy of CL 3725570

	Removed Enable Fullscreen option from editor's Window menu on Mac. Windowed fullscreen mode is currently unavailable on Mac in editor mode as supporting it properly would require it to work with multiple spaces and split screen, which we currently don't handle (requested in UE-27240)

	#jira UE-51709

Change 3728875 by Michael.Trepka

	Fixed compile error in Mac SlateOpenGLContext.cpp

Change 3728880 by Matt.Kuhlenschmidt

	Guard against invalid worlds in thumbnail renderers

Change 3728924 by Michael.Trepka

	Don't defer MacApplication->CloseWindow() call. This should fix a rare problem with deferred call executing during Slate's PrepassWindowAndChildren call.

	#jira UE-51711

Change 3729288 by Joe.Graf

	Added the .idea/misc.xml file generation to speed up CLion indexing

Change 3731008 by Lauren.Ridge

	Changing Layers and Blends from proxy assets to real assets

Change 3731026 by Arciel.Rekman

	libelf: make elf_end() visible (UE-51843).

	- This repairs compilation for a case when CUDA is being used.
	- Also added some missing files for ARM 32-bit.

Change 3731081 by Lauren.Ridge

	New material layer test assets

Change 3731186 by Josh.Engebretson

	Adding camera speed scalar setting and Toolbar UI to increase range on camera speed presets

	#jira UE-50104

Change 3731188 by Mike.Erwin

	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 3731682 by Arciel.Rekman

	UnrealEd: Allow unattended commandlets to rename/save packages.

Change 3732305 by Michael.Dupuis

	#jira UE-48434 : Only register if the foliage type still has a valid mesh

	#jira UE-51891

Change 3732895 by Josh.Engebretson

	https://jira.it.epicgames.net/browse/UE-51706

	If a shared DDC is not being used, present a notification to the licensee with a link on how to setup a shared DDC.
	Adds DDC notification events for check/put and query for whether a shared DDC is in use.

	#jira UE-51706

Change 3733025 by Arciel.Rekman

	UBT: make sure new clang versions are invoked.

Change 3733311 by Mike.Erwin

	Fix Linux compile warning from CL 3731188

	It didn't like mixing && and || without parentheses. Reworked logic to do one test at a time, put cheaper tests first to avoid calls to more expensive IsPluginFolder.

Change 3733658 by Josh.Engebretson

	Add a missing #undef LOCTEXT_NAMESPACE

Change 3734003 by Arciel.Rekman

Change 3734978 by Jamie.Dale

	Relaxed enum property importing to allow valid numeric values to be imported too

	This was previously made more strict which caused a regression in Data Table importing

	#jira UE-51848

Change 3734999 by Arciel.Rekman

	Linux: add LTO support and more.

	- Adds ability to use link-time opitimization (reusing current target property bAllowLTCG).
	- Supports using llvm-ar and lld instead of ar/ranlib and ld.
	- More build information printed (and in a better organized way).
	- Native scripts updated to install packages with the appropriate tools on supported systems
	- AutoSDKs updated to require a new toolchain (already checked in).
	- Required disabling OpenAL due to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219089

Change 3735268 by Matt.Kuhlenschmidt

	Added support for canvas based DPI scaling.

	-Scene canvas is by default not scaled as this could severely impact any game using a canvas based UI
	-The debug canvas for stats is always dpi scaled in editor and pie.
	-Eliminated text scaling workaround now that the entire canvas is properly scaled
	-Enabled canvas scaling in cascade UI

Change 3735329 by Matt.Kuhlenschmidt

	Fix potential crash if an asset editor has an object deleted out from under it

	#jira UE-51941



Change 3735502 by Arciel.Rekman

	Fix compile issue (bShouldUpdateScreenPercentage).

Change 3735878 by Jamie.Dale

	Updated FString::SanitizeFloat to allow you to specify the min number of fractional digits to have in the resultant string

	This defaults to 1 as that was the old behavior of FString::SanitizeFloat, but can also be set to 0 to prevent adding .0 to whole numbers.

Change 3735881 by Jamie.Dale

	JsonValue no longer stringifies whole numbers as floats

Change 3735884 by Jamie.Dale

  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 3454934 by Chris.Bunner

	Backing out changelists 3441680, 3454636 and 3454844 for the sake of integration stability.

Change 3629223 by Rolando.Caloca

	DR - Rollback //UE4/Dev-Rendering/Engine/Source/Runtime/VulkanRHI to changelist 3627847

	3617483

Change 3636145 by Chris.Bunner

	Linux compile fix.

Change 3636198 by Chris.Bunner

	Include fix.

Change 3636225 by Daniel.Wright

	Removed spammy draw event

Change 3636397 by Daniel.Wright

	Visualize volumetric lightmaps uses 18% grey in lit mode

Change 3636398 by Daniel.Wright

	Translucency lighting modes work with Volumetric Lightmaps
	* The old Indirect Lighting Cache always interpolated one sample per object, while Volumetric lightmaps operate at the frequency of the Translucency Lighting Mode (per-vertex or per-pixel) so the lighting accuracy is much higher.
	* The old ILC always applied the single lighting sample with a per-pixel normal, even in per-vertex lighting modes
	* Volumetric PerVertex NonDirectional (cheapest lit translucency) went from 74 instructions down to 42
	* Volumetric Directional went from 104 up to 122

Change 3636604 by Chris.Bunner

	Added a material translation error on identically named/associated but differently valued parameters as this will cause one of them to be lost during parameter evaluation, the result being "random".

Change 3637668 by Rolando.Caloca

	DR - hlslcc - Skip preprocessor when not required which reduces peak mem consumption by ~500 MB
	- Fix missing indexing on intrinsic return type

Change 3638541 by Chris.Bunner

	Fixed editor materials - Skip hardcoded parameter names that we rely on being overridden when checking for non-matching duplicate parameters.

Change 3638798 by Mark.Satterthwaite

	Rebuilt hlslcc for Mac for Rolando's 3637668 changes.

Change 3638861 by Mark.Satterthwaite

	Missed making a log verbose in the Metal ring-buffer.

Change 3639482 by Rolando.Caloca

	DR - vk - Minor fixes

Change 3639909 by Michael.Lentine

	Add special case for struct needed to compile.
	Workaround issues in parser such that (x)[0] is replaced with x[0] and (x).a is replaced with x.a.

Change 3639916 by Michael.Lentine

	Spelling fix.

Change 3640053 by Mark.Satterthwaite

	Fix Desktop Forward rendering on Nvidia Metal rendering on macOS by modifying the shader and runtime to treat ForwardLocalLightBuffer data as uint rather than float and invert the use of as*() casts.

	Tthis is *necessary* to avoid a bug/limitation of Nvidia's current Metal shader compiler that flushes all denorm values to zero on load from any resource. AMD & iOS Metal only flush-to-zero when sampling from textures and that's what Apple regard as the expected behaviour. I have however asked them to standardise on the D3D behaviour of preserving denorms on all load, move (incl. min/max/as*()-casts) & store operations. This won't happen in the current or imminent OS/Xcode releases.

	Now only Intel Metal is broken and their problems run deeper.

	#jira UE-48881

Change 3640983 by Olaf.Piesche

	Cache the depth buffer collision shader for GPU particles even when simple forward is enabled, as that can be turned off at runtime.

	#jira UE-48799

Change 3641480 by Michael.Lentine

	Add min16float to FP16Math

Change 3642442 by Mark.Satterthwaite

	Fix the native shader libraries again & undo the increase in cook time from changes to the way FShaderCodeLibrary was compiling & deduplicating the shaders.
	- Remvoe the single linear array for accumulated shader code: reallocating this is tremendously expensive and will double the time taken to iteratively cook large projects.
	- Uncompress the shader data for the native library system so that it actually works again.
	- Fix some errant change to the Metal compiler that was trying to wedge the fully compiled library into the single Metal library which is 100% bogus.

	#jira UE-49192

Change 3642919 by Chris.Bunner

	Reverted unintended changes to material static parameter set serialization.
	Bumped material version to force re-serialization.
	Fixed a few typos.

Change 3642923 by Richard.Wallis

	Fix for "Pixel Inspector On" message not disappearing when closing pixel inspector window while on.  Handle tab closed events to cancel the pixel inspector if window closed while running.

	#jira UE-46504

Change 3643296 by Michael.Lentine

	Convert all structures that aren't use globally to halfs.

Change 3643381 by Ryan.Brucks

	New Plugin allowing Blueprint Texture and RT reads as well as MIC creation and modification.

Change 3643929 by Ben.Salem

	Added better precision on thread values in Perf Monitor. Also added global thread values to go with per-world ones to help track down the most accurate numbers possible.

	#tests Ran locally, changes validated by benj

Change 3644203 by Mark.Satterthwaite

	Refactor mtlpp a little bit to make the compiler do more of the work & update for all the latest publicly exposed APIs.

Change 3644336 by Mark.Satterthwaite

	Ref-count the mtlpp Device object so that it can be the repository for IMP caching - now just have to go through the types created from a specific device and have them keep a reference....

Change 3644431 by Uriel.Doyon

	Added a intensity units property, for point lights and spot lights, that can be set to Candelas, Lumens or Unitless (legacy).
	The default units value for newly placed point lights and spot lights is configured in the project settings.
	Spot lights configured in lumens have their whole luminous energy redirected toward the cone.
	This means that changing the outer cone angle, changes the spot light brightness.
	New exposure menu that uses an EV100 slider.
	New post process settings "camera" tab regrouping : ShutterSpeed, ISO,  Aperture and ExposureCompensation.
	Post process settings "auto exposure" tab renamed "exposure".
	The calibration constant for "Auto Exposure Basic" is now configurable in the advanced tab.
	The auto exposure method is renamed "Metering Mode"

	New pre-exposure feature that allows the engine to apply the previous frame exposure before writing to the scene color.
	This allows the engine to render the scene with similar range than the final color (after exposure), and avoid arithmetic overflow for low precision RT formats.
	The amount of exposure applied directly is called pre-exposure, and is compensated by a smaller post-exposure value.

Change 3645098 by Marcus.Wassmer

	Don't add meshes twice when in simpleforward

Change 3645551 by Daniel.Wright

	VolumetricScatteringIntensity is greyed out based on Mobility

Change 3645707 by Chris.Bunner

	Skip empty parameters when identifying invalid duplicates during material translation.

Change 3646225 by Uriel.Doyon

Change 3646323 by Rolando.Caloca

	DR - vk - Fix bad update texture 2/3d parameters

Change 3646463 by Mark.Satterthwaite

	Metal shader files that can serve as extensions to the metal_stdlib rather than trying to wedge even more into the shader compiler. Might as well leverage Metal's C++'ness.
	Currently just a skeleton of a buffer type that would better emulate HLSL Buffer<>/RWBuffer<> objects.

Change 3646727 by Marcus.Wassmer

	fix linux and nonunity compiles

Change 3647777 by Rolando.Caloca

	DR - Mobile Vulkan optimization

Change 3647822 by Lauren.Ridge

	Layers are now renameable (except Layer 0 is always "Background") in Material Layers Functions

Change 3647918 by Chris.Bunner

	Static analysis fixes - Monolithic include, forward delcared enums, locally shadowed variable.

Change 3648010 by Michael.Lentine

	Don't use min16float by default.

Change 3648015 by Michael.Lentine

	Add special case fixes for min16float as well as half on console.

Change 3648024 by Lauren.Ridge

	Moving MaterialLayersFunctions Layer naming to EditorOnly wrappers

Change 3648127 by Lauren.Ridge

	Moving name getter functionality to FMaterialLayersFunctions

Change 3648265 by Lauren.Ridge

	Fixing loctext key

Change 3648293 by Rolando.Caloca

	DR - D3D12 fix

Change 3648326 by Rolando.Caloca

	DR - vk - Added subrectangle support when updating Texture2D and Texture3D

Change 3648522 by Rolando.Caloca

	DR - vk - Do not try to create a BufferView of a StructuredBuffer (no valid pixelformat)

Change 3648612 by Rolando.Caloca

	DR - vk - Implement RHIMapStagingSurface

Change 3648673 by Rolando.Caloca

	DR - vk - Reduce Vulkan pipeline cache disk size by filtering duplicated shader ucodes

Change 3648913 by Arne.Schober

	DR - Performance optimization during HLod traversal. using vector load and avoiding array copy by passing it through reference instead through value.

Change 3649443 by Daniel.Wright

	Exposed EmissiveBoost, since Lightmass supports Emissive areas on meshes

Change 3650436 by Mark.Satterthwaite

	Implemented the necessary extensions for Metal shading language to move lots of complexity out of MetalBackend and into actual shader code to make life *vastly* simpler.

	- Full ue4::typed_buffer<T> wrapper type & associated ue4::buffer<>/ue4::buffer_atomic<> API - totally untested but should be functionally equivalent to HLSL Buffer<T>/RWBuffer<T>.
	- All the sensible casts I can think of are now defined in ue4_format - any additional ones can just be added. The enurm of formats needs to be exposed to MetalRHI so we upload the correct values, but this should be trivial.
	- Added a full series of wrappers around texturecube_array and depthcube_array to insulate code from whether it is backed by a real cube_array or a texture2d_array so we don't have to maintain complicated variants for new/old iOS devices.
	- Added implementations for a bunch of annoying HLSL & GLSL intrinsics that were being matched by name + reverse_bits which needs a custom implementation on old shader standards.

Change 3650861 by Rolando.Caloca

	DR - vk - Fix warnings

Change 3651116 by Rolando.Caloca

	DR - vk - Support for compressed saved PSO cache

Change 3651321 by Rolando.Caloca

	DR - vk - Prep for load multiple PSO files

Change 3651337 by Chris.Bunner

	Editor-only default material fallback (hardcoded material).

	#jira UE-48404

Change 3651839 by Rolando.Caloca

	DR - vk - Integrate minor pipeline changes

Change 3652042 by Mark.Satterthwaite

	More work on mtlpp:
	- Selector class that caches IMP from SEL & Class.
	- Fixes to ns::Error.
	- Added test case application for testing denorm & float reinterpret-cast behaviour on Metal.

Change 3652370 by Uriel.Doyon

	New "stat StreamingOverview" giving high level metrics of texture usage.
	New function ResetAverageRequiredTexturePoolSize() and GetAverageRequiredTexturePoolSize() giving the average ideal value for "r.streaming.poolsize".

Change 3653658 by Chris.Bunner

	Material vertex interpolator for sprite and gpu sprite particles.

Change 3653676 by Rolando.Caloca

	DR - vk - Integrate changes: Multiple PSO caches, shared ucode & compression, size reduction up to 80%

Change 3653940 by Daniel.Wright

	Moved Volumetric Lightmap textures out of FScene and into FPrecomputedVolumetricLightmapData so their lifetime can match the MapBuildData.  This allows tossing the source BulkData in game after RHI texture creation even though switching lighting scenarios does Release/InitializeRenderingResources multiple times.

Change 3653956 by Daniel.Wright

	Fixed leak of BatchVisibilityId's

Change 3653991 by Daniel.Wright

	Fixed missing include

Change 3654013 by Daniel.Wright

	Temporarily disabed a material error whilst working with content teams to fix the introduced bugs.

Change 3654534 by Daniel.Wright

	Editor is only supported on Feature Level 5 platforms.  Added a message box and exit when SM4 is detected (d3d10, OpenGL 3).

Change 3654751 by Rolando.Caloca

	DR - vk - Add readback for RGB10A2; minor optimization

Change 3654940 by Rolando.Caloca

	DR - vk - Warning fix

Change 3655104 by Mark.Satterthwaite

	Add a bunch of code to mtlpp to wrap the Xcode command-line Metal tools and use them to provide a convenient command-line tool that can compile two Metal shaders & diff the resulting AIR to make debugging easier. Obviously this only works on macOS.

Change 3655173 by Jian.Ru

	Render dithered material as masked if a stencil prepass is not used

	#jira UE-50064, UE-49537

Change 3655479 by Daniel.Wright

	Fixed HandleLegacyMapBuildData not getting called on P maps loaded in the editor, which apparently was dropped in an integration error, causing all legacy maps (before the BuildData change) to lose their built lighting.

Change 3656341 by Richard.Wallis

	Metal validation checks to test for drawing of the end of a vertex stream as seen in UE-48172 (Landscape Mesh Flickers Rapidly When Using Sculpting Landscape).  This is not a fix for that but just a error log to catch the bad draw calls.

	#jira UE-48172

Change 3656844 by Rolando.Caloca

	DR - vk - Avoid microcode copy
	- Fix link error

Change 3656894 by Rolando.Caloca

Change 3657401 by Rolando.Caloca

	DR - vk - Linux compile fix

Change 3657607 by Rolando.Caloca

	DR - vk - Prep for changes

Change 3658722 by Chris.Bunner

	Refresh shared texture samplers when changing max ansiotropy level (e.g. scalability settings).

	#jira UE-30086

Change 3659499 by Daniel.Wright

	Moved bEnableAutoLODGeneration to LOD category so it's not the only one in HLOD category

Change 3659644 by Mark.Satterthwaite

	D3D11 equivalent to 3656341 (only enabled when -d3ddebug is) to validate DrawIndexedPrimitives isn't trying to draw off the end of the instanced vertex streams which has inconsistent (and potentially undefined) behaviour across the various APIs we support. This fires when painting the landscape because the code attempts to render with a FirstInstance value that is as large as the number of elements in the instance-data streams which D3D11 drivers silently fails to render, but which Metal (& probably Vulkan too) will renders as garbage. This pattern is wrong & will be even more dangerous in a Draw*Indirect world.

	#jira  UE-48172

Change 3659831 by Rolando.Caloca

	DR - vk - Copy 3657927 (fixes for Mali)

Change 3661921 by Rolando.Caloca

	DR - vk - Minor log/info changes

Change 3661985 by Mark.Satterthwaite

Change 3662050 by Richard.Wallis

	Compile fix for Metal enums.

Change 3662062 by Rolando.Caloca

	DR - Copy from 3662060
	- OpenGL cloth fix

Change 3662100 by Mark.Satterthwaite

	Use a temporary file and an atomic move to put the Metal PCH into the right place and reduce the number of false PCH compile failures on the build farm.

Change 3662253 by Daniel.Wright

	Reflection Captures support Lighting Scenarios without recapturing
	 * Reflection Captures are now part of the Map Build
	 * Modifying a capture in editor will display a preview, but game can only display built captures (black for unbuilt with screen message)
	 * Reflection Capture build data moved to the BuildData package
	 * Building lighting / reflection captures no longer dirties ULevels
	* Sky lights which capture the scene now work correctly with Lighting Scenarios
	* Lighting Scenarios must now be loaded for each time they are made visible (no switching back and forth while keeping both loaded)

Change 3663215 by Mark.Satterthwaite

	Initial, incomplete, tool added to mtlpp to help debug macOS Internal Compiler Errors - the mtlpp command-line tool can be fed the debug output from UE4 along with compiler settings to automatically compile shaders and construct the render pipeline that crashes the runtime compiler.
	So far only macOS render-pipeline-states are supported currently.

Change 3663293 by Mark.Satterthwaite

	Added Metal device selection to the mtlpp command-line tool so I can quickly test compile on dual-GPU Macbook Pro's.

Change 3663471 by Daniel.Wright

	Reflection Capture Builds no longer use UEditorLevelUtils::SetLevelVisibility to control level visibility, which streams out sublevels, modifying nav mesh
	Fixed status updates during Reflection Capture Build
	Captures overflowing GMaxNumReflectionCaptures now log a warning instead of pretending that they built successfully

Change 3664056 by Rolando.Caloca

	Replaces some custom material node to get View.BufferSizeAndInvSize with ViewProperty material expression in some engine material functions.

Change 3667239 by Rolando.Caloca

	DR - Use hlslcc define for common issues

Change 3668108 by Brian.Karis

	Disabled to Catmull-Rom filter. Too many flickering issues. Disabled antiflicker as well.

Change 3668157 by Mark.Satterthwaite

	In the prototype Metal stdlib extension library add inline versions of the D3D SM6 "wave" intrinsics that can be expressed in terms of Metal 2.0 simd/quad group operations (macOS=simd, iOS=quad). These are unlikely to be as efficient as direct intrinsics but they should be functionally equivalent.

	These functions are not available *yet* as I still need to hook the ue4_stdlib into MetalShaderFormat & MetalRHI.

Change 3668260 by Olaf.Piesche

	Cache particle collision shaders regardless of simple forward state

	Missed this checkin

	#jira FORT-51307

Change 3669243 by Daniel.Wright

	Bumped shader version to propagate FReflectionCaptureData rename

Change 3669369 by Mark.Satterthwaite

	Duplicating Metal changes from //UE4/Release-4.18 to Dev-Rendering (//UE4/Dev-Rendering)

	3662503 Collapse system-variables to one declaration in MetalUtils to avoid later shader compiler errors when they are specified more than once, which is seemingly permissable. Fixes volumetric fog.

	#jira UE-50293

	3665210 - Invalidate all Metal shaders again to force a recompile to workaround another driver bug.
	- On macOS compact the clip-distance value into a single output to avoid bugs in the runtime pipeline compilers.
	- In SCW's direct-compile mode MetalShaderForamt should always dump the resulting Metal shader and print any errors we encounter to the log.
	- Change FGenerateMetalVisitor to take a FMetalCodeBackend& not a FMetalCodeBackend* to avoid a lot of pointless pointer validation.

	#jira UE-50244

	3665429 Fix a crash on shutdown due to MetalRHI caching vertex-declarations beyond the lifetime of the RHI by moving the cache into the FMetalDynamicRHI itself.
	#jira UE-50356

	3665613 Fix DistanceField rendering on Metal & the associated validation layer error when it is enabled - MetalRHI can't use the same approach as Vulkan without a bit more work.

	#jira UE-50364

	3667584 Fix black flickering on some materials that use World Position Offset - the Metal sincos intrinsic comes into two flavours for single precision floats and we want the precise version not the fast version. The "cross" implementation needed a few more fma's too and this change has to invalidate Metal shaders again to take effect.
	#jira UE-50399

	3667805 Changing sincos in Metal fragment shaders had undesirable side-effects - the compiler is now re-associating another floating point operation - so limit the use of precise::sincos to vertex-shaders for now. This fixes the WPO materials without causing any other obvious problems.
	#jira UE-50399

Change 3669912 by Mark.Satterthwaite

	Fix Metal compilation for PCSS shadows - the HLSL that is compiled uses both SampleCmp and Sample which GLSL disallows (shadowSampler types in GLSL only allow SampleCmp) but is perfectly valid in Metal where only the texture type declaration changes.

	Duplicate MetalBackend.cpp changes from Joe.Graf's: 3667781
	Fixed an extra ) being emitted during HLSL->Metal translation
	Added depthcube_array support per Mark's instructions

Change 3670308 by Mark.Satterthwaite

	Missing autorelease pool blocks in MetalTexture functions.

Change 3670989 by Mark.Satterthwaite

	Stop trying to be so clever with Metal clip-distances: AMD have a bug in 10.13.0 that means we can only emit one clip-distance value, so simply emit the value with the lowest index (we have handily ordered them by importance!) and let the others become user-interpolators until this bug is resolved in a macOS SU (according to Max@AMD the fix is in, just not in time for 4.18). This means planar reflections will work, VR no-multi-view-fallback will work & layered rendering will work either individually or together - the difference being that on macOS *only* the VR no-multi-view-fallback & layered rendering paths may be slower when combined with the global clip plane.

	Hit & run fix to MetalCaptureManager and availability of tile-shader functions while I'm here.

	#jira UE-50518

	Stop syncing CPU with GPU on Vulkan

Change 3671637 by Rolando.Caloca

	DR - Copy 3670937
	Fixes Vulkan editor outline

Change 3672309 by Mark.Satterthwaite

	Submitted on behalf of Richard Wallis:

	Only disable V-Sync on Metal in macOS 10.13 when running in "true" fullscreen mode (where we switch display modes & forbid switching spaces or tabbing out) so that you won't see the rainbow artefact caused by being out-of-sync with WindowServer, only the tearing you'd expect when V-Sync is disabled. We'll chat with Apple about whether there is a way to avoid the rainbow artefact when switching spaces in Windowed Fullscreen with displaySync disabled.

	#jira UE-50134

Change 3672314 by Daniel.Wright

	User friendly message dialog for when a required key is missing from BaseLightmass.ini

Change 3672315 by Daniel.Wright

	Assert on load when a uniform buffer struct goes missing, instead of a crash on save

Change 3672476 by Chris.Bunner

	Removed duplicate material instance editor command binding that appeared in a task stream merge.

Change 3672626 by Mark.Satterthwaite

	Move the ue4_stdlib.metal extensions to MetalRHI's Public header directory as it'll need to be available to both modules and that's easier to accomplish from here.

Change 3672643 by Mark.Satterthwaite

	iOS compilation fixes.

Change 3672728 by Daniel.Wright

	Fixed encoded HDR reflection captures

Change 3672753 by Jian.Ru

	Fix texture swimming
	#jira UE-49369

Change 3672815 by Daniel.Wright

	Tooltip for build button explaining why it might be disabled

	DR - Remove global variable with semantic

Change 3673514 by Rolando.Caloca

	DR - vk - compile fix

Change 3675899 by Chris.Bunner

	Fixed support for editor-time transient parameter overrides. This happens when a compiled material's scalar or vector parameter is changed in value only, the active material resources should also update and be reverted when the material graph is closed. The code was incorrectly pulling base parameters from expressions instead of the actual uniform.

Change 3676843 by Arne.Schober

	DR - UE-49473 - Fix Stateleak caused by custom drawer in the long for loop, where the depth stencil state might not be reset in a subsequent itteration of the loop.

Change 3678269 by Daniel.Wright

	Fixed Encoded HDR reflection capture data getting the wrong Brightness applied when cooking

Change 3678543 by Daniel.Wright

	MapBuildData now tosses the unneeded reflection capture format on load.  Affects target platforms that require multiple formats at cook time.

Change 3679602 by Jian.Ru

	Fix up mesh decal shader complexity view mode
	#jira UE-50272

Change 3679959 by Chris.Bunner

	Fixed logic on overriden vector parameter retrieval for material instances checking a function owned parameter.

	#jira UE-50712

	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

	#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

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

	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 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

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 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 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.

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

	DR - vk - Redo some changes from DevMobile
	3601439
	3604186
	3606672
	3617383
	3617474
	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

	#jira UE-49431

Change 3631076 by Rolando.Caloca

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

	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.

	#jira UE-49381

Change 3634820 by Mark.Satterthwaite

	Change the hash-function for the preprocessed HLSL source in FMetalShaderOutputCooker to reduce risk of hash-collisions. Fixes one cause of UE-49381 and reveals an underlying driver bug on iOS 9 with runtime-compiled text shaders *only*.

	#jira UE-49381

Change 3634821 by Mark.Satterthwaite

	Force Metal shaders only to recompile by incrementing the format version.

	#jira UE-37458

Change 3352947 on 2017/03/17 by Phillip.Kavan

	#jira UE-42510 - Instanced static mesh transform edits are now reflected in the Blueprint editor's preview scene.

	Change summary:
	- Added IPropertyHandle::GetValueBaseAddress() (interface).
	- Modified IPropertyHandle::NotifyPostChange() to include EPropertyChangeType as an optional input.
	- Added FPropertyHandleBase::GetValueBaseAddress() (implementation).
	- Modified FPropertyHandleBase::NotifyPostChange() to include the optional input arg in the property change event.
	- Modified FPropertyHandleBase::CreatePropertyNameWidget() to clear the override text after temporarily replacing display name/tooltip text for the creation of the SPropertyNameWidget. This was done to allow for transactions to be named according to the property that's being modified.
	- Modified FMathStructProxyCustomization::OnValueCommitted() to only apply the input value while not interactively editing via spinbox as well as when not post-processing an undo/redo (which can trigger a focus loss).
	- Modified the FMathStructProxyCustomization::OnEndSliderMovement() delegate to include property handle and proxy value input parameters, as well as to call FlushValues() as part of the implementation.
	- Modified FlushValues() for each of FMatrixStructCustomization, FTransformStructCustomization and FQuatStructCustomization to explicitly handle both propagation and transaction processing.
	- Modified UInstancedStaticMeshComponent::UpdateInstanceTransform() to call Modify() prior to applying changes (so that the previous state is recorded when inside a transaction context).
	- Modified FInstanceStaticMeshSCSEditorCustomization::HandleViewportDrag() to propagate changes to all instances of the ISMC archetype.

	Known issues:
	- Using the spinbox to edit instanced mesh transform values in the Blueprint editor will not apply the change to instances in the level editor until after you release the mouse button (i.e. - it will not be shown as a "live" update).

Change 3353678 on 2017/03/20 by Michael.Dupuis

	properly unfreeze the culling of foliage when toggling the freezerendering command

Change 3353747 on 2017/03/20 by Matt.Kuhlenschmidt

Change 3353909 on 2017/03/20 by Matt.Kuhlenschmidt

	Fixed actors showing thumbnails in details panel and made a few other tweeks to thumbnail displays in details panels
	- The color of the accepted type is now  shown properly
	- All object based properties now have thumbnails on by default.

Change 3353948 on 2017/03/20 by Nick.Darnell

	UMG - Updating the background blur widget's upgrade code to use the custom version, and handling older cases that were continuing to generate blur slots, even when already upgraded.

Change 3354335 on 2017/03/20 by Nick.Darnell

	Paragon - Excluding Archetype objects from reporting references, which causes crashes in the fast template mode.

Change 3354495 on 2017/03/20 by Nick.Darnell

	Core - Making it so order that outers are discovered does not matter, initializing the chain of outers if hasn't been created when instancing subobjects.

Change 3354578 on 2017/03/20 by Nick.Darnell

	Slate - There's now a console variable option, Slate.VerifyHitTestVisibility (off by default) which enables additional visibility checks for widgets.  Normally this isn't nessesary, but if you're changing the visibility of widgets during a frame, and several hit tests need to be performed that frame there's a chance that a button could be clicked twice in one frame.  Enabling this mode will make all hit testing more expensive, so for now it's off by default, but available for licensees that need the extra testing.

Change 3354737 on 2017/03/20 by Nick.Darnell

	Core - Adding a fix to Dev-Editor from that enables objects in the same package being requested to also be loaded.  This came about during async streaming callbacks alerting that a requested class was done loading, but there were still other assets in the package 'not loaded' but were available, just needed post load called on them.

Change 3355923 on 2017/03/21 by Yannick.Lange

	VR Editor: - Remove unnecessary cleanup functions.
	- Initialize with VR Mode and remove SetOwner function, since it shouldn't be possible to reset the VR Mode afterwards.

Change 3355959 on 2017/03/21 by Yannick.Lange

	VR Editor: - Rename VREditorWorldInteraction to VREditorPlacement, to avoid confusion with ViewportWorldInteraction. VREditorPlacement will only handle placing objects from content browser in the VR Mode.
	- Removed SnapSelectedActorsToGround to VREditorMode.

Change 3355965 on 2017/03/21 by Yannick.Lange

	VR Editor:  Forgot to add files to previous submit 3355959.

	- UI system fix check on VRMode on shutdown.

Change 3356028 on 2017/03/21 by Nick.Darnell

	Slate - SButton now correctly releases mouse capture even if it becomes disabled while pressed, but before 'click' has been fired.

	#jira UE-42777

Change 3356071 on 2017/03/21 by Yannick.Lange

	VR Editor: Copy of change 3353663.
	- Fix having to press once on the landscape to see the visuals for landscape editing.
	- Fix when sculpting/painting the position wouldn't update.
	- Fix inverted action for brushes while holding down shift or modifier on motioncontroller.
	- Cleanup FLandscapeToolInteractorPosition.

	- Change from 3353663: Use TStrokeClass::UseContinuousApply and TimeSinceLastInteractorMove to decide when to apply ToolStroke on tick.

Change 3356180 on 2017/03/21 by Michael.Dupuis

	Added ShowFlag Foliage Occlusion Bounds
	Fixed non initialized variable
	Expose changing Min Occlusion Bounds instead of assuming 6

	#rn none

Change 3356347 on 2017/03/21 by Nick.Darnell

	UMG - Introducing a faster CreateWidget.  When cooking, the widget compiler now generates a widget template/archetype that is stored in the same package as the generated blueprint class.  During compiling we generate a nearly fully initialized widget tree including all sub userwidgets and their trees, hookup all member variables, initialize named slots, setup any animations...etc.  This nearly fully constructed widget can be instanced using it as an archetype in the NewObject call, and does not have to use the correspondingly slow StaticDuplicateObject path.  There are restrictions on this method, part of the compiling step for widgets now inspects if the instancing would be successful, or if there would be GLEO references after instancing because a user forgot to setup Instanced on a subobject property.  Luckily that should be few and far between, all UVisuals (Widgets & Slots) are now DefaultToInstanced, which takes care of the overwhelming cases that demand the instanced flag.  Especially given the bulk of cases using BindWidget in native code.

	UMG - Removing a lot of deprecated functions from 4.8 on UUserWidget.

Change 3356357 on 2017/03/21 by Nick.Darnell

	Build - Fixing some IWYU issues on the incremental build.

Change 3357176 on 2017/03/21 by Alex.Delesky

	#jira UE-42445 - TMaps now support editing the values of structs that act as map keys. TMaps with struct keys will now show the types of their elements in the details panel as well, and structs will now also display numbers next to set elements.

Change 3357197 on 2017/03/21 by Alex.Delesky

	#jira none - Fixing build issue for TMap key struct change.

Change 3357205 on 2017/03/21 by Michael.Dupuis

	Forgot to reset min granularity to 6 from testing

Change 3357340 on 2017/03/21 by Arciel.Rekman

	Mark FMallocAnsi (standard libc malloc) thread-safe on Linux.

Change 3357413 on 2017/03/21 by matt.kuhlenschmidt

	Added '/Game/Effects/Fort_Effects/Materials/Smoke/M_Main_Smoke_Puff.M_Main_Smoke_Puff' to collection 'MattKTest'

	Upgraded collection 'MattKTest' (was version 1, now version 2)

Change 3357505 on 2017/03/21 by Alexis.Matte

	Fix to avoid changing the CDO of FbxAssetImportData. The UI was saving the Config which was saving the CDO. But already serialized data will be reload badly if the CDO change since we serialize only the diff.

Change 3362631 on 2017/03/24 by Jamie.Dale

	Split the monolithic culture concept in UE4

	UE4 has historically only supported the concept of a single monolithic "culture" that applied to both text localization and internationalization, as well as all asset localization. Typically the "culture" was set to the "locale" of the OS, however that could be undesirable or incorrect on platforms (such as newer versions of Windows) that have a distinct concept of "language" (for localization) and "locale" (for internationalization).

	This change splits the concept of "culture" into "language" and "locale", and also adds the concept of "asset groups". The language is now used to work out which localization we should use, and the locale is used to control how numbers/dates/times/etc are formatted within our internationalization library.

	Asset groups expand on the language used by asset localization and allow you to create a group of asset classes that can be assigned a different culture than the main game language. A typical use-case of this would be creating an "audio" group that could, for example, be set to Japanese while the rest of the game runs in English.

	If your game doesn't care about the distinction between language and locale, and doesn't need to use asset groups, then you're able to continue to use "culture" as you always have. If, however, you do care about those things, then you'll likely want to avoid using the "culture" directly (as it's now a very aggressive setting that overrides all others), and instead favor using language/locale (games will typically treat these as the same) and asset groups as separate concepts (both in settings, and in your in-game UI).

	The language or locale for a game can be controlled by settings within the "Internationalization" section of your configs (this would typically be set in your GameUserSettings config, in the same way that "culture" works), eg)

	  [Internationalization]
	  language=fr
	  locale=fr

	The asset groups for a game can be controlled by settings within the "Internationalization.AssetGroupClasses" and "Internationalization.AssetGroupCultures" sections of your configs (the asset group class definition would typically be set in your DefaultGame config, and the cultures the groups use would typically be set in your GameUserSettings config), eg)

	  [Internationalization.AssetGroupClasses]
	  +Audio=SoundWave
	  +Audio=DialogueWave

	  [Internationalization.AssetGroupCultures]
	  +Audio=ja

	- Skip a couple of rasterize by flipping either the X texels or the Y texels when possible.
	- Keep the best chart raster so that we don't need to reraster when adding the chart to the layout.
	- Added a lightmap UV version in StaticMesh so that we don't invalidate the lighting cache. Only use the new lightmap UV generation when going through UStaticMesh::Build which invalidates the lighting.

	- Adding _API specifiers to MovieSceneAudioTrack, MovieSceneAudioSection, and FAudioTrackEditor so they can be subclassed in other modules.
	- Made GetSoundDuration function in MovieSceneAudioTrack.cpp a member function so it's functionaliy could be reused by subclasses.

	Sequencer: PreRoll and PostRoll is now exposed at the section level, for all sections
	  - For the majority of sections this will be unimplemented, but it will allow for some tracks to set up their data ahead of time

Change 3364896 on 2017/03/26 by Max.Chen

	Sequencer: Add segment flags to equality operator for movie scene evaluation segments
	  - This prevents them from being accumulated into adjacent segments of the same index and forced time, but differing flags

Change 3364897 on 2017/03/26 by Max.Chen

	Sequencer: Fixed "Evaluate in preroll" and "Evaluate in Postroll" options
	  - Pre and postroll flags now come through on compiled segments, so the previous manual logic for sub sections is obsolete; we can just use the compiled segment data directly.

Change 3364898 on 2017/03/26 by Max.Chen

	Sequencer: Moved track options to be accessible on all nodes, and operate on all selected tracks

Change 3364902 on 2017/03/26 by Max.Chen

	Sequencer: Ensure evaluation flags are considered when compiling segments from external sequences
	  - This ensures that preroll regions in sub sequences are correctly evaluated when their parent section has preroll
	  - Changed high pass blending to always allow preroll

Change 3364903 on 2017/03/26 by Max.Chen

	Engine: Moved proxy mesh transform update out of camera view computation code

Change 3364927 on 2017/03/26 by Max.Chen

	Sequencer: Added the ability to selectively restore state for specific anim type IDs for a given object
	  - This allows us to specifically restore one particular type of animation for a given object (ie, transform, skeletal animation control, or motion blur)

Change 3364928 on 2017/03/26 by Max.Chen

	Sequencer: Fixed sub-sub tracks not being present in master sequences
	  - In order to correctly handle preroll in inner-inner sequences, we need to have access to those tracks when compiling intermediate sub sections. By caching off all the inner templates, we can have access to these tracks to check whether they want to be evaluated in pre/post roll in the master sequence

Change 3364937 on 2017/03/26 by Max.Chen

	Sequencer: Update cine camera component debug focus plane on tick, rather than in GetCameraView

	Sequencer: Fixed section template script struct
	  - Because the cpp is not parsed by UHT, the empty template had its parent struct, rather than its own
	  - We now just return null, and handle empty segments correctly in the segment remapper as part of the track compilation

Change 3365013 on 2017/03/26 by Max.Chen

	Sequencer: Added data validation on compiled template loads, and extra guards against misuse of movie scene types

Change 3365014 on 2017/03/26 by Max.Chen

	  - This fixes a hack that was previously in place from the old PostTickRenderFixup that caused it to run that step after scrubbing bad finished. This is no longer necessary, and actually breaks clicking to set the scrub position, as it now means that we step across the entire range between the previous and current time.

	UMG - Improving some logging for fast widget creation.

Change 3368826 on 2017/03/28 by Nick.Darnell

	Slate - Slate Application now maintains seperate tracking for each pointer being utilized for drag drop, so now multiple fingers on multiple widgets can now simultaneously be attempting a drag, however once one of them becomes successful, we clear all state of all other tracking since only one Drag Drop operation is possible at a time.

	Slate - bFoldTick is now removed from the codebase, we haven't supported the other (non-folded) code path for awhile, so there was no point in maintaining the switch.

	Slate - Users have noticed issues where the cursor does not appear when changing visibility (through toggling the way the cursor appears).  This was rooted in how the OS requested cursor changes, WM_SETCURSOR on Windows only asks for new cursors when the mouse moves, but often cursors change just because mouse capture changes.  So now the path has been centralized in Slate Tick to only handle the cursor changes in one place, and several places that need to refresh the cursor state, now set a flag to handle it on next tick.

	Sequencer: Level streaming improvements
	  - Tick prerequisites are now set up when any object binding is resolved, not at the start of the sequence. This unifies code between spawnables and possessables, and allows tick prerequisites to still be set up when levels are streamed in
	  - Actor references are no longer resolved when a PIEInstance is specified on the package, and it cannot be fixed up to a different ptr than the original. This stops us resolving actors from one world into another.

Change 3219884 on 2016/12/02 by Daniel.Wright

	Assert to help track down rare crash locking capsule indirect shadow vertex buffer

Change 3219885 on 2016/12/02 by Daniel.Wright

	Fixed saving a package that doesn't exist on disk but exists in p4 at a newer revision when the user chooses 'Mark Writable'

Change 3219886 on 2016/12/02 by Daniel.Wright

	Don't create projected shadows when r.ShadowQuality is 0
	* Fixes crash in the forward path trying to render shadows
	* In the deferred path, the shadowmap was still being rendered and only the projection skipped, now all cost will be skipped

Change 3219887 on 2016/12/02 by Daniel.Wright

	Changed ClearRenderTarget2D default alpha to 1, which is necessary for correct compositing

Change 3219893 on 2016/12/02 by Daniel.Wright

	AMD AGS library with approved TPS
	Disabled DFAO on AMD pre-GCN PC video cards to workaround a driver bug which won't be fixed (Radeon 6xxx and below)

Change 3219913 on 2016/12/02 by Daniel.Wright

	Level unload of a lighting scenario propagates the lighting scenario change - fixes crash when precomputed lighting volume data gets unloaded

Change 3220029 on 2016/12/02 by Daniel.Wright

	Async shader compiling now recreates scene proxies which are affected by the material which was compiled.  This fixes crashes which were occuring as proxies cache various material properties, but applying compiled materials would not update these cached properties (bRequiresAdjacencyInformation).
	* A new ensure has been added in FMeshElementCollector::AddMesh and FBatchingSPDI::DrawMesh to catch attempts to render with a material not reported in GetUsedMaterials
	* Fixed UParticleSystemComponent::GetUsedMaterials and UMaterialBillboardComponent::GetUsedMaterials
	* FMaterialUpdateContext should be changed to use the same pattern, but that hasn't been done yet

Change 3220108 on 2016/12/02 by Daniel.Wright

	Fixed shadowmap channel assignment for stationary lights which are not in a lighting scenario level, when a lighting scenario level is present

Change 3220504 on 2016/12/03 by Mark.Satterthwaite

	Metal Desktop Tessellation support from Unicorn.
	- Apple: Metal tessellation support added to MetalShaderFormat, MetalRHI and incl. changes to engine runtime/shaders for Desktop renderer and enabled in ElementalDemo by default (OS X 10.11 will run SM4).
	- Epic: Support for different Metal shader standards on Mac, iOS & tvOS which required moving some RHI functions around as this is a project setting and not a compile-time constant.
	- Epic: Fragment shader UAV support, which is also tied to newer Metal shader standard like Tessellation.
	- Epic: Significant refactor of MetalRHI's internals to clearly separate state-caching from render-pass management and command-encoding.
	- Epic: Internal MetalRHI validation code is now cleanly separated out into custom implementations of the Metal @protocol's and is on by default.
	- Epic: Various fixes to Layered Rendering for Metal.
	- Omits Mobile Tessellation support which needs further revision.

	Removed obsolete check() in FMetalSurface constructor

Change 3223450 on 2016/12/06 by Chris.Bunner

	Added explicit ScRGB output device selection rather than Nvidia-only hardcoded checks. Allows easier support for Mac and other devices moving forward.

Change 3223638 on 2016/12/06 by Michael.Trepka

	Restored part of the check() in FMetalSurface constructor removed in CL 3223371

Change 3223642 on 2016/12/06 by Mark.Satterthwaite

	Experimental Metal EDR/HDR output support for Mac (iOS/tvOS need custom formats & shaders so they are not supported yet).
	- Only available on macOS Sierra (10.12) for Macs with HDR displays (e.g. Retina iMacs).
	- Enable with -metaledr command-line argument as it is off-by-default.
	- Sets up the CAMetalLayer & the back-buffer for RGBA_FP16 output on Mac using DCI-P3 as the color gamut and ACES 1000 nit ScRGB output encoding.

Change 3224199 on 2016/12/06 by Mark.Satterthwaite

	Fix a dumb copy-paste error from the HDR changes to Metal.

Change 3224220 on 2016/12/06 by Mark.Satterthwaite

	Fix various errors with Metal UAV & Render-Pass Restart support so that we can use the Pixel Shader culling for DistanceField effects.
	- Unfortunately Metal requires that a texture be bound to start a render-pass, so reuse the dummy depth-stencil surface from the problematic editor preview tile rendering.

Change 3224236 on 2016/12/06 by Mark.Satterthwaite

	IWYU CIS compile fix for iOS.

Change 3224366 on 2016/12/06 by Mark.Satterthwaite

	Simplify some of the changes from CL# 3224220 so that we don't perform unnecessary clears.
	- If the RenderPass is broken to issue compute or blit operations then treat the cached RenderTargetsInfo as invalid, unless the RenderPass is restarted.
	- This guarantees that we don't erroneously ignore calls to SetRenderTargets if the calling code issues a dispatch between two RenderPasses that use the same RenderTargetsInfo.

Change 3224416 on 2016/12/06 by Uriel.Doyon

	New default implementation for UPrimitiveComponent::GetStreamingTextureInfo using a conservative heuristic where the textures are stretched across the bounds.
	Optimized UPrimitiveComponent::GetStreamingTextureInfoWithNULLRemoval by not handling registered components with no proxy (essentially hidden game / collision primitives).

	Added blueprint support for texture streaming built data through FStaticMeshComponentInstanceData.

	Fix for material texture streaming data not being available on some cooked builds.

	Enabled split requests on all texture load requests (first loading everything visible and then loaded everything not visible).
	This is controlled by "r.Streaming.MinMipForSplitRequest" which defines the minimum mip for which to allow splitting.
	Forced residency are now loaded in two steps (visible, then forced), improving reactiveness.

	Updated "stat streaming" to include "UnkownRefMips" which represent texture with no known component referencing them,
	and also "LastRenderTimeMips" which related to timed primitives.
	Changed "Forced Mips" so that it only shows mips that are loaded become of forced residency.

	"Texture Streaming Build" now updates the map check after execution.

	Removed Orphaned texture logic as this has  become irrelevant with the latest retention priority logic.

	Updated "r.streaming.usenewmetrics" so that it shows behavior before and after 4.12 improvements.

Change 3224532 on 2016/12/07 by Uriel.Doyon

	Integrated CL 3223965 :

	Building texture streaming data for materials does not wait for pending shaders to finish compilation anymore.
	Added more options to allow the user to cancel this build also.

Change 3224714 on 2016/12/07 by Ben.Woodhouse

	Cherry pick CL 3223972 from //fortnite/main:

	Disable Geometry shader onchip on XB1. This saves 4ms for a single shadow casting point light @ 512x512 (4.8ms to 1.8ms)

Change 3224715 on 2016/12/07 by Ben.Woodhouse

	New version of d3dx12.h from Microsoft which incorporates my suggested static analysis fixes. This avoids us diverging from the official version

Change 3224975 on 2016/12/07 by Rolando.Caloca

	#jira UE-19394

Change 3225486 on 2016/12/07 by Chris.Bunner

	Only disable TAA during HighResScreenshots if we don't have a reasonable frame-delay enabled.

	- Make some macros into lambdas
	#jira UE-39143

Change 3226212 on 2016/12/07 by Daniel.Wright

	Features which require a full prepass use DDM_AllOpaque instead of DDM_AllOccluders, which can be skipped if the component has bUseAsOccluder=false

Change 3226213 on 2016/12/07 by Daniel.Wright

	Scene Capture 2D can specify a global clip plane, which is useful for portals
	* Requires the global clip plane project setting to be enabled

Change 3226214 on 2016/12/07 by Daniel.Wright

	Improved deferred shadowing with MSAA by upsampling light attenuation intelligently in the base pass
	* If the current fragment's depth doesn't match what was used for deferred shadowing, the neighbor (cross pattern) with the nearest depth's shadowing is used
	* Edge artifacts can still occur where the upsample fails or the shadow factor was computed per-sample due to depth / stencil testing
	* Indirect Occlusion from capsule shadows also uses the nearest depth neighbor UV for no extra cost
	* Base pass on 970 GTX 1.69ms -> 1.85ms (.16ms) in RoboRecall

Change 3227063 on 2016/12/08 by Mark.Satterthwaite

	For Metal platforms ONLY temporarily disable USE_LIGHT_GRID_REFLECTION_CAPTURE_CULLING to avoid UE-37436 while the Nvidia driver team investigate why this doesn't work for them but does for the others. This won't affect non-Metal platforms and the intent is to revert this prior to 4.16 provided we can work through the problem with Nvidia.

Change 3227376 on 2016/12/08 by Mark.Satterthwaite

	Must not include a private header inside the MenuStack public header as that causes compile errors in plugins.

Change 3227415 on 2016/12/08 by Mark.Satterthwaite

	Fix shader compilation due to my disabling of USE_LIGHT_GRID_REFLECTION_CAPTURE_CULLING on Metal - InstancedCompositeTileReflectionCaptureIndices needs to be defined even though Metal doesn't support instanced-stereo rendering.

Change 3227516 on 2016/12/08 by Daniel.Wright

	Implemented UWidgetComponent::GetUsedMaterials

Change 3227628 on 2016/12/08 by Daniel.Wright

	Removed redundant ResolveSceneDepthTexture from the merge

Change 3227635 on 2016/12/08 by Daniel.Wright

	Forward renderer supports shadowing from movable lights and light functions
	* Only 4 shadow casting movable or stationary lights can overlap at any point in space, otherwise the movable lights will lose their shadows and an on-screen message will be displayed
	* Light functions only work on shadow casting lights since they need a shadowmap channel to be assigned

Change 3227660 on 2016/12/08 by Rolando.Caloca

	DR - vk - Fix r.MobileMSAA on Vulkan
	- r.MobileMSAA is now read-only (to be fixed on 4.16)
	- Show time for PSO creation hitches
	#jira UE-39184

Change 3227704 on 2016/12/08 by Mark.Satterthwaite

	Fix Mac HDR causing incorrect output color encoding being used, HDR support is now entirely off unless you pass -metaledr which will enable it regardless of whether the current display supports HDR (as we haven't written the detection code yet). Fixed the LUT/UI compositing along the way - Mac Metal wasn't using volume LUT as it should have been, RHISupportsVertexShaderLayer now correctly returns false for non-Mac Metal platforms.

Change 3227705 on 2016/12/08 by Daniel.Wright

	Replaced built-in samplers in the nearest depth translucency upsample because the built-in samplers are no longer bound on PC (cl 2852426)

Change 3227787 on 2016/12/08 by Chris.Bunner

	Added extent clear to motion blur pass to catch misized buffers bringing in errors.

	Merging //UE4/Dev-Main@3228528 to Dev-Rendering (//UE4/Dev-Rendering)

Change 3228940 on 2016/12/09 by Mark.Satterthwaite

	Editor fixes for 4.15:
	- PostProcessTonemap can't fail to bind a texture to the ColorLUT or the subsequent rendering will be garbage: the changes for optimising stereo rendering forgot to account for the Editor's use of Views without States for the asset preview thumbnails. Amended the CombineLUT post-processing to allocate a local output texture when there's no ViewState and read from this when this situation arises which makes everything function again.
	- Don't start render-passes without a valid render-target-array in MetalRHI.

Change 3228950 on 2016/12/09 by Mark.Satterthwaite

	Make GPUSkinCache run on Mac Metal - it wasn't working because it was forcibly disabled on all platforms but for Windows D3D 11.
	- Fixed the Skeleton editor tree trying to access a widget before it has been constructed.
	- Enable GPUSkinCache for Metal SM5: doesn't render correctly, even on AMD, so needs Radar's filing and investigation.
	#jira UE-39256
