5f27a8dbcb [Upgrade Notes Critical! Licensee build scripts and DeviceProfiles may need updating]
- Formalizing all TargetPlatforms to have a Client version, rename WindowsNoEditor to Windows, and removing DDPI specification of TargetPlatforms, and generate them programmatically
- Updated names DeviceProfiles and Build scripts, as above
- Some PlatformInfo class cleanup
- Added a TNonDesktopTargetPlatformBase class to make most TargetPlatforms simpler
- Added "No Compiled Support" to the Turnkey LaunchOn menu when the TargetPlatforms aren't compiled in (to show that even if you install an SDK, you will need to compile before you can LaunchOn)\
- Starting the transition away from PlatformInfo::FPlatformInfo to FDDPI

ccc1743281 - Big TargetPlatform Module cleanup:
- Removed the function to return a single TP, and wrapped the functionality in a simple single required function (platform just has to add TPs to an array, high level code manages init and cleanup of the array)
  - Stripped unncessary code from all TPs
  - Collapsed the desktop targetplatform modules into 1 per platform
  - Renamed LinuxAArch64NoEditorTargetPlatfortm to LinuxAArch64TargetPlatform to match the other non-editor platforms
  - Deleted AllDesktopPlatform

ae9401146d Remove all support for Metal prior to Metal 1.2 on iOS/tvOS and Metal 2.0 on macOS. This permits some fairly radical simplifications and removal of a number of workarounds.
- All Buffer<>/RWBuffer<> objects are now bound as texture2d or texture_buffer, unless they are 3-component, in which case they are bound as raw T* buffer pointers.
- 3-component Buffer/RWBuffer objects should now work - Metal needed to use packed_* types internally as normal 3-component types in Metal are the same size as 4-component types which is different to HLSL. This is untested as we have no such example.
- Texture Gather/GatherCompare operations have been fixed and should now work.
- Remove all the TypedBufferFormat function-constant specialisation infrastructure and metadata as it is no longer necessary.
- Remove all the raw-conversion for 1, 2 and 4 component vector types as it is no longer required.
- Fixed input qualifiers (centroid, linear, etc.) for Fragment shader inputs - they should now work.
- Remove a bunch of Metal specific shader changes due to buffer type casting and swizzling that will now just work.
- Use the BGRA vertex format for FColor on Metal when available (everywhere but iOS/tvOS 10 using Metal 1.2).
- Simplify ShouldCompilePermutation & similar functions now that we have fewer versions to support.

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

Change 3805828 by Gil.Gribb

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

Change 3806784 by Ben.Marsh

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

Change 3807549 by Graeme.Thornton

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

Change 3807727 by Graeme.Thornton

	Unhide the text asset format experimental editor option

Change 3807746 by Josh.Engebretson

	Remove WER from iOS platform

Change 3807928 by Robert.Manuszewski

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

Change 3808221 by Steve.Robb

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

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

Change 3809233 by Graeme.Thornton

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

Change 3809518 by Ben.Marsh

	Remove the outdated UnrealSync automation script.

Change 3809643 by Steve.Robb

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

	#jira UE-53037

Change 3809862 by Steve.Robb

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

	#jira UE-42593

Change 3811190 by Graeme.Thornton

	Add support for writing specific log channels to their own files

Change 3811197 by Graeme.Thornton

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

Change 3811257 by Robert.Manuszewski

	Cluster creation will now be time-sliced

Change 3811565 by Steve.Robb

	Define out non-monolithic module functions.

Change 3812561 by Steve.Robb

	GitHub #3886 : Enable Brace-Initialization for Declaring Variables

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

	#jira UE-48242

Change 3812864 by Steve.Robb

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

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

	#jira UE-53089

Change 3820358 by Ben.Marsh

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


Change 3822594 by Ben.Marsh

	UAT: Improvements to log file handling.

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

Change 3823695 by Ben.Marsh

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

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

Change 3823845 by Ben.Marsh

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

Change 3824180 by Ben.Marsh

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

	#jira

Change 3825777 by Steve.Robb

	Fix to return value of StringToBytes.

Change 3825810 by Ben.Marsh

	UBT: Reduce length of include paths for MSVC toolchain.

Change 3825822 by Robert.Manuszewski

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

Change 3826734 by Ben.Marsh

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

Change 3827730 by Steve.Robb

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

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

Change 3827745 by Steve.Robb

	Initializer list support for TMap.

Change 3827770 by Steve.Robb

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

	#jira UE-53813

Change 3829189 by Ben.Marsh

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

Change 3830444 by Steve.Robb

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

Change 3830718 by Ben.Marsh

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

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

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

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

	#jira UE-53845

Change 3831064 by Ben.Marsh

	Fix log file contention when spawning UBT recursively.

Change 3832654 by Ben.Marsh

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

Change 3832680 by Ben.Marsh

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

Change 3832695 by Ben.Marsh

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

Change 3833528 by Ben.Marsh

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

Change 3833543 by Ben.Marsh

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

Change 3834354 by Robert.Manuszewski

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

	#jira UE-52035

Change 3834400 by Robert.Manuszewski

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

	#jira UE-52035

Change 3834947 by Steve.Robb

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

Change 3835004 by Ben.Marsh

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

Change 3835340 by Ben.Marsh

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

Change 3835972 by Ben.Marsh

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

Change 3836019 by Ben.Marsh

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

Change 3836269 by Ben.Marsh

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

Change 3836543 by Ben.Marsh

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

Change 3836546 by Ben.Marsh

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


Change 3836805 by Ben.Marsh

	Fix commandlet to compile marketplace plugins.

Change 3836829 by Ben.Marsh

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

Change 3837036 by Ben.Marsh

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

Change 3837037 by Ben.Marsh

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

Change 3837040 by Ben.Marsh

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

Change 3837247 by Ben.Marsh

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

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

Change 3837262 by Ben.Marsh

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

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

Change 3837343 by Ben.Marsh

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

Change 3837356 by Ben.Marsh

	Fix invalid character encodings.

Change 3837727 by Graeme.Thornton

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

Change 3837823 by Ben.Marsh

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

Change 3837831 by Graeme.Thornton

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

Change 3837857 by Robert.Manuszewski

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


Change 3837943 by Robert.Manuszewski

	PR #4405: Fix FGarbageCollectionTracer (Contributed by mhutch)


Change 3838451 by Ben.Marsh

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

	#jira UE-53996

Change 3839519 by Ben.Marsh

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

Change 3843790 by Graeme.Thornton

	UnrealPak: Log the size of all encrypted data

Change 3844258 by Ben.Marsh

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

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

	#jira UE-54157

Change 3845796 by Ben.Marsh

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

Change 3845823 by Ben.Marsh

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

	#jira UE-54123

Change 3845901 by Arciel.Rekman

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

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

	(Edigrating 3819174 to Dev-Core)

Change 3846439 by Ben.Marsh

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

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

Change 3816608 by Ben.Marsh

	UBT: Use DirectoryReference objects for all include paths.

Change 3816954 by Ben.Marsh

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

Change 3816986 by Ben.Marsh

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

Change 3816991 by Ben.Marsh

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

Change 3823090 by Ben.Marsh

	UAT: Improve logging for child UAT instances.

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

Change 3826082 by Ben.Marsh

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

Change 3827025 by Ben.Marsh

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

Change 3829927 by James.Hopkin

	Made HTTP interface const correct

Change 3833533 by Ben.Marsh

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

Change 3835826 by Ben.Marsh

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

Change 3835969 by Ben.Marsh

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

Change 3837777 by Steve.Robb

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

Change 3838569 by Steve.Robb

	Algo moved up a folder.

Change 3513112 by Richard.Wallis

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

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

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

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

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

	#jira UE-33982

Change 3517069 by Yujiang.Wang

	Fix for ScissorRect settings in d3d11 being lost under certain scenarios

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

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

Change 3525461 by Daniel.Wright

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

	#jira UE-48342

Change 3587866 by Mark.Satterthwaite

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

Change 3588168 by Mark.Satterthwaite

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

	#jira UE-48163

Change 3590961 by Mark.Satterthwaite

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

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

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

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

Change 3590965 by Mark.Satterthwaite

	Remove the Z-bias workaround from Metal MRT as it isn't required and actually causes more problems.

	Remove support for Mac OS X El Capitan (10.11) including the stencil view workaround.
	Bump the minimum Metal shader standard for Metal SM4, SM5 & Metal MRT to v1.2 (macOS 10.12 Sierra & iOS 10) so we can use FMAs and other newer shader language features globally.
	Enable the new GRHIRequiresRenderTargetForPixelShaderUAVs flag as Metal is like Vulkan and needs a target for fragment rendering.
	Also fix the filename for direct-compile & remove the old batch file generation in the Metal shader compiler.

Change 3592171 by Rolando.Caloca

Change 3594999 by Mark.Satterthwaite

	Disable MallocBinned2 for iOS as on Rhino it worked but on iOS 10.0.2 there are bugs (munmap uses 64kb granularity, not the 4096 the code expects given the reported page-size).
	While we are here remove the spurious FORCE_MALLOC_ANSI from the iOS platform header.

	#jira UE-48342

Change 3595004 by Mark.Satterthwaite

	#jira UE-48748

Change 3606009 by Mark.Satterthwaite

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

	#jira UE-47663

Change 3606108 by Mark.Satterthwaite

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

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

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

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

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

Change 3358837 on 2017/03/22 by Joe.Graf

	Merge of pull request #3214 for the RenderDocPlugin

	#CodeReview: matt.kuhlenschmidt, marcus.wassmer
	#rb: marcus.wassmer

	* Planar reflections are now supported in splitscreen

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

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

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

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

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

	[Copy] Disabled selection color on Volume materials

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

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

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

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

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

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

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

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

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

	Updated items from original shelved version by Mark Satt:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Change 3219796 on 2016/12/02 by Rolando.Caloca

	DR - vk - Increase timeout to 60ms

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.

	DR - Lambdaize
	- Added quicker method to check if system textures are initialized

Change 3222290 on 2016/12/05 by Mark.Satterthwaite

	Moved HLOD persistent data to viewstate to fix per-view compatability.
	#jira UE-37539

Change 3223349 on 2016/12/06 by Chris.Bunner

	Fixed HLOD with FreezeRendering command.
	#jira UE-29839

Change 3223371 on 2016/12/06 by Michael.Trepka

	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 3223830 on 2016/12/06 by Rolando.Caloca

	DR - vk - Better error when finding an invalid Vulkan driver
	#jira UE-37495

Change 3223869 on 2016/12/06 by Rolando.Caloca

	DR - vk - Reuse fences

Change 3223906 on 2016/12/06 by Guillaume.Abadie

	Fix alpha through TempAA artifact causing a small darker edge layouts.

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

	DR - vk - Dump improvements

Change 3225012 on 2016/12/07 by Rolando.Caloca

	DR - Show warning if trying to use num samples != (1,2,4,8,16)

Change 3225126 on 2016/12/07 by Chris.Bunner

	Added 'force 128-bit rendering pipeline' to high-res screenshot tool.
	#jira UE-39345

Change 3225449 on 2016/12/07 by Chris.Bunner

	Updated engine rendering defaults to better match current best practices.
	#jira UE-38081

Change 3225485 on 2016/12/07 by Chris.Bunner

	Moved QuantizeSceneBufferSize to RenderCore and added call for PostProcess settings. Fixes screenpercentage out-of-bounds reads in some cases.
	#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.

Change 3225505 on 2016/12/07 by Daniel.Wright

	Fixed exponential height fog disappearing with no skybox

Change 3225655 on 2016/12/07 by Benjamin.Hyder

	Updating TM-Shadermodels to include Translucent lighting, Two sided, updated cloth animation, and adjusted lighting.

Change 3225668 on 2016/12/07 by Chris.Bunner

	Dirty owning packages when user manually forces regeneration of all reflection captures.
	#jira UE-38759

Change 3226139 on 2016/12/07 by Rolando.Caloca

	DR - Fix recompute tangents disabling skin cache
	- 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 3226258 on 2016/12/07 by Rolando.Caloca

	DR - Typo fix

Change 3226259 on 2016/12/07 by Rolando.Caloca

	#jira UE-39143

Change 3226932 on 2016/12/08 by Chris.Bunner

	Re-saved Infiltrator maps to update reflection captures.
	#jira UE-38759

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.
	#jira UE-37436

Change 3227120 on 2016/12/08 by Gil.Gribb

	Merging //UE4/Dev-Main@3226895 to Dev-Rendering (//UE4/Dev-Rendering)

Change 3227211 on 2016/12/08 by Arne.Schober

	DR - UE-38585 - Fixing crash where HierInstStaticMesh duplication fails. Also reverting the fix from UE-28189 which is redundant.

Change 3227257 on 2016/12/08 by Marc.Olano

	Extension to PseudoVolumeTexture for more flexible layout
	Change by ryan.brucks

Change 3227286 on 2016/12/08 by Rolando.Caloca

	DR - Fix crash when using custom expressions and using reserved keywords
	#jira UE-39311

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 3227521 on 2016/12/08 by Guillaume.Abadie

	Fixes post process volume's indirect lighting color.

	#jira UE-38888

Change 3227567 on 2016/12/08 by Marc.Olano

	New upscale filters: Lanczos-2 (new default), Lanczos-3 and Gaussian Unsharp Mask

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.
	Added early out to clear call when excluded region matches RT region.
	#jira UE-39437

Change 3228177 on 2016/12/08 by Marc.Olano

	Fix DCC sqrt(int) error

Change 3228285 on 2016/12/08 by Chris.Bunner

	Back out changelist 3225449.
	#jira UE-39528

Change 3228680 on 2016/12/09 by Gil.Gribb

	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

Change 3229013 on 2016/12/09 by Mark.Satterthwaite

	Further tidy up in SSkeletonTreeView as suggested by Nick.A.

Change 3229101 on 2016/12/09 by Chris.Bunner

	Log compile error fix and updated cvar comments.

Change 3229236 on 2016/12/09 by Ben.Woodhouse

	XB1 D3D11 and D3D12: Use the DXGI frame statistics to get accurate GPU time unaffected by bubbles

Change 3229430 on 2016/12/09 by Ben.Woodhouse

	PR #2680: Optimized histogram generation. (Contributed by PjotrSvetachov)

	Profiled on nvidia 980GTX (2x faster), and on XB1 (marginally faster)

Change 3229580 on 2016/12/09 by Marcus.Wassmer

	DepthBoundsTest for AMD.

Change 3229701 on 2016/12/09 by Michael.Trepka

	Changed "OS X" to "macOS" in few places where we display it and updated the code that asks users to update to latest version to check for 10.12.2

Change 3229706 on 2016/12/09 by Chris.Bunner

	Added GameUserSettings controls for HDR display output.
	Removed Metal commandline as this should replace the need for it.

Change 3229774 on 2016/12/09 by Michael.Trepka

	Disabled OpenGL on Mac. -opengl is now ignored, we always use Metal. On old Macs that do not support Metal we show a message saying that the app requires Metal and exit.

Change 3229819 on 2016/12/09 by Chris.Bunner

	Updated engine rendering defaults to better match current best practices.
	#jira UE-38081

Change 3229948 on 2016/12/09 by Rolando.Caloca

	DR - Fix d3d debug error
	#jira UE-39589

Change 3230341 on 2016/12/11 by Mark.Satterthwaite

	Don't fatally assert that the game-thread stalled waiting for the rendering thread in the Editor executable, even when running -game as the rendering thread can take a while to respond if shaders need to be compiled.
	#jira UE-39613

Change 3230860 on 2016/12/12 by Marcus.Wassmer

	Experimental Nvidia AFR support.

Change 3230930 on 2016/12/12 by Mark.Satterthwaite

	Disable RHICmdList state-caching on Mac - Metal already does this internally and depends on receiving all state changes in order to function.

Change 3231252 on 2016/12/12 by Marcus.Wassmer

	Fix NumGPU detection. (SLI only crash)

Change 3231486 on 2016/12/12 by Mark.Satterthwaite

	Fix a stupid mistake in MetalStateCache::CommitResourceTable that would unnecessarily rebind samplers.

Change 3231661 on 2016/12/12 by Mark.Satterthwaite

	Retain the RHI samplers in MetalRHI to guarantee lifetime.
