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

Change 3358140 on 2017/03/22 by Rolando.Caloca

	DR - Fix copy to cube face
	- Compile fix when using dump layer
	- Add new error enum

Change 3358301 on 2017/03/22 by Mitchell.Wilson

	Initial check in of LODs in InfiltratorForward. First pass on optimization in level. Adding a visibility track for SceneCapture2D in tunnel section.

Change 3358477 on 2017/03/22 by Mitchell.Wilson

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

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

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

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

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

	* Planar reflections are now supported in splitscreen

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

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

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

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

	[Copy] Distance field cvar comments

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

	[Copy] Disabled selection color on Volume materials

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

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

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

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

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

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

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

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

	Volumetric fog supports static shadowing from Stationary lights
	* Using bilinear on static shadowmap depths + 1 PCF to smooth out results

Change 3366029 on 2017/03/27 by Daniel.Wright

	Static shadow depth maps for Stationary point and spot lights are 2x higher res by default (4x more texels), which is more appropriate for volumetric fog

	Missed a file.

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

	Updated items from original shelved version by Mark Satt:

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

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

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

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

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

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

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

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

	Fixed linux build hopefully

Change 3368001 on 2017/03/28 by Mark.Satterthwaite

Change 3368019 on 2017/03/28 by Mark.Satterthwaite

	And another fix for Windows compilation of MetalShaderFormat.

Change 3368042 on 2017/03/28 by Mark.Satterthwaite

	And a couple of simpler MSVC errors.

	Remove temp working directories after archive packages built.

Change 3371641 on 2017/03/30 by Rolando.Caloca

	DR - Copy 3371640 (fix mem leak)

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

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

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

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

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

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

	[Experimental] Partial compute post process pipeline (r.PostProcess.PreferCompute).
	StencilSceneTexture added to deferred list.
	A few known issues to be fixed in a follow-up CL.

Change 3372765 on 2017/03/30 by Uriel.Doyon

	Disabled concurrent call to NotifyPrimitiveUpdated while we don't have a safe concurrent update

Change 3372979 on 2017/03/30 by Richard.Hinckley

	#jira UE-43501

Change 3373053 on 2017/03/30 by Simon.Tourangeau

	LPV Fade support
	- mostly integrated from CL 2959511

Change 3373272 on 2017/03/30 by Uriel.Doyon

	Added support for the concurrent update of dynamic primitives by the streaming manager.

	Refactored common param code to shared sub-class in CombineLUTs and Tonemap PS/CS.
	Skip compute post process out-of-bounds writes.
	Unsigned type conversion fixes.
	Trimmed compute post process shader inputs.

Change 3374233 on 2017/03/31 by Chris.Bunner

	Removed several redundant post process compute fences and resource transitions.
	Added testing CVar to force compute post processes to async (r.PostProcess.ForceAsyncDispatch).

Change 3374412 on 2017/03/31 by Rolando.Caloca

	DR - Fix static analysis

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

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

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

	Copying Metal improvements from task stream, with some modifications:
	- Off-by-default implementations for MTLFence & MTLHeap, including some small changes to the RHI interface for parallel contexts.
	- Support for Apple's Instruments "Points of Interest" tool.
	- Consolidation of some Mac & iOS compiler, memory and thread handling code.
	- Fixes for Metal not having implicit buffer SRV typecasting for DistanceField effects.
	- Improvements to the internal FMetalDebug layer, still off by default.
	- Limited support for Xcode automatic code-signing for iOS/tvOS.
	- Minimisation of render-target changes in some rendering code, esp. SceneOcclusion, DBufferDecals.
	- Added RHISetResourceAliasability_RenderThread to FDynamicRHI for RHIs to implement simple render-target aliasing.
	- Added FApplePlatformObject, a custom block allocator for Objective-C types (with NSZombie support) which is now used in MetalRHI to decrease allocation costs of Objective-C types.
	- Smattering of lesser fixes.

Change 3375654 on 2017/03/31 by Mark.Satterthwaite

	Incremental Windows build fix.

	Submitting initial HDR test map (WIP)

Change 3376756 on 2017/04/03 by Guillaume.Abadie

	Fixes scene captures ordering's backward compatibility.

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