Change 3310176 on 2017/02/17 by Chris.Bunner
Merging CL 3233886: AMD HDR support (requires r.AMDSupportsHDRDisplayOutput=1 in ini).
Update to AGS 5.0.5.
Partial code tidy up.
Change 3310187 on 2017/02/17 by Chris.Bunner
Preserve constant expressions rather than always casting after translating a material attribute. Losing the notion of constant means we can't correctly detect used properties and falsely enable e.g. PDO. Happened because of the incorrect component masks in BreakMaterialNodes which then had to be downcast to the correct type which is done as an inline fragment rather than swizzle expression.
#jira UE-41594
Change 3310215 on 2017/02/17 by Chris.Bunner
Prevent SpeedTree node compiling for skeletal meshes (not supported as uses more UV sets than available).

Preparing TM_Shadermodels map for automation
Change 3328222 on 2017/03/01 by Chris.Bunner
Prevent decals from drawing in separate translucency pass. Whilst user control and material relevance were already removed, if the flag was checked before being disabled (by swapping to decal domain) this was still being read in the render loop, now explicitly ignores decals.

[Copy] Changing movable skylight properties no longer affects static draw lists
Change 3333693 on 2017/03/06 by Daniel.Wright
[Copy] Added 'r.AOListMeshDistanceFields' which dumps out mesh distance fields sorted by memory size, useful for directing content optimizations
Change 3333705 on 2017/03/06 by Daniel.Wright
[Copy] Mesh distance fields are now 8 bit fixed point by default, but can be changed back to 16 bit floating piont with a project setting.
* 8 bit uses half memory but introduces error for thin surfaces or large meshes.
Change 3333721 on 2017/03/06 by David.Hill
DecalProxy:
Copy float FadeScreenSize to FDeferredDecalProxy for use in the render thread. This avoids pointer chasing to the UDecalComponent (game thread component).
Change 3333772 on 2017/03/06 by Daniel.Wright
[Copy] Scene motion blur data is only updated for the main renderer frames. Fixes scene captures and planar reflections breaking object motion blur.
Change 3333790 on 2017/03/06 by Daniel.Wright
[Copy] Mesh distance field generation uses Embree, for a 2.5x speedup

Change 3333822 on 2017/03/06 by Daniel.Wright
[Copy] Moved mesh distance field code into MeshDistanceFieldUtilities.cpp
* Moved FMeshUtilities to its own header so the 8k line MeshUtilites.cpp file can be further split up

Non-editor compile fix
Change 3333836 on 2017/03/06 by Daniel.Wright
[Copy] Workaround for gobal distance field volume textures being bloated by 4x on PS4 due to the recommended tiling modes. They now use a 2d tiling mode which avoids the bloat, saving 96Mb.
Change 3333843 on 2017/03/06 by Daniel.Wright
[Copy] Added OcclusionExponent to skylight component
* Useful for brightening up indoors without losing contact shadows as MinOcclusion does

Change 3333857 on 2017/03/06 by Daniel.Wright
[Copy] Clear light attenuation for local lights with a quad covering their screen extents
* Clearing the entire light attenuation buffer costs .1ms on PS4. This optimization lowers the minimum cost of a shadow casting light from .15ms -> .03ms.
* Shadowed lights in Fortnite with 25 lights 3.7ms -> 1.42ms on PS4
Change 3333860 on 2017/03/06 by Daniel.Wright
[Copy] Flush deferred deletes when reallocating distance field atlas to reduce peak memory
Change 3333861 on 2017/03/06 by Daniel.Wright
[Copy] Disable all distance field features on Intel cards as HD 4000 hangs in the RHICreateTexture3D call to allocate the large atlas
Change 3333869 on 2017/03/06 by Daniel.Wright
[Copy] Volumetric Fog using a volume texture mapped to the camera frustum
* Volumetric fog can be enabled on an Exponential Height Fog component with additional controls
* Lights have a VolumetricScatteringIntensity
* New cvars r.VolumetricFog, r.VolumetricFog.GridPixelSize, r.VolumetricFog.GridSizeZ, r.VolumetricFog.DepthDistributionScale
* Lighting features supported:
* Directional light with CSM and a light function
* Point / spot lights without shadows / light functions / IES profiles
* Skylight with occlusion from distance fields
* Analytical height fog covers the view range past where the volumetric fog ends
* Temporal reprojection is used on the volumetric fog scattering and extinction to achieve stability
* Translucency integrates properly into volumetric fog
* Height fog StartDistance is not supported by volumetric fog and should be set to 0.
Change 3333894 on 2017/03/06 by Daniel.Wright
[Copy] Initialize GDummyVolumetricFogGlobalDataUniformBuffer outside of parallel rendering
Change 3333902 on 2017/03/06 by Daniel.Wright

[Copy] Fixed volumetric fog trying to render light functions for a point light
Change 3333908 on 2017/03/06 by Daniel.Wright
[Copy] Volumetric materials
* Added new material domain Volume, which can output Scattering, Absorption and Emissive. All properties are in world space densities.
* Particle systems using the Volume domain are voxelized based on their ParticlePosition and ParticleRadius
* Volumetric fog integration is now energy conservative - scattering is integrated against transmission over the depth of each slice.
* Added bOverrideLightColorsWithFogInscatteringColors to exponential height fog, which can be enabled to make Volumetric Fog match Height fog more closely
Change 3334134 on 2017/03/06 by Daniel.Wright
[Copy from Michael Trepka] Added Embree 2.14.0 and changed MeshUtilities to use it as this solves issues with Embree leaking TLS keys. UnrealLightmass is still using older Embree 2.7.0 until we can find time to properly test it with the new version. Also, invalidated distance field DDC to force it to rebuild with updated Embree.

* Forward lighting of local lights can be forced with 'r.VolumetricFog.InjectShadowedLightsSeparately 0'
* Shadowed lights come at a cost: 2.9ms for volumetric fog on 970 -> 4.2ms with shadowing

Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

Change 3122544 on 2016/09/13 by Ben.Woodhouse
Shadow stencil optimisation with cvar (enabled by default)
Avoids redundant clearing the stencil buffer for per-object and pre shadows by zeroing the stencil during testing, following discussion on UDN.
This means we don't benefit from Hi Stencil on GCN for the shadow projection draw calls, but it's still faster in all the cases I could find, including for the player character where the bounding box is quite large. (Note: early stencil still works fine, according to PIX)
Shadow projection GPU time profiling :
Test map with 35 characters, stationary directional light
- 4ms-2ms on XB1
- 2.5ms to 0.9ms on PC (r9-390X)
- 3ms-2ms on PS4
Paragon PS4 (roughly 20% reduced - from ~0.39ms)

Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))).

Fix for ensure fail when initializing point light shadowmaps.
This came about because cubemap rendertargets always have Extents of (Resolution, 0). The Y component was implicitly used to determine if it was a cubemap, which is odd... The fix was to make the definition explicit via a flag and initialize both the X and Y parameters.
I suspect the ensure started happening recently due to a more recent change, but fixing the underlying logic seems like the correct fix.

Change 3131625 on 2016/09/19 by Mark.Satterthwaite
Inside MetalRHI add an optional cache for disposed texture objects so we may reuse them - controlled by CVAR rhi.Metal.TextureCacheMode which must be set prior to running as it can't be changed at runtime. Settings: 0 = off, 1 (default) = will attempt to reuse private memory texture objects within the frame they are released otherwise they are disposed of as before. Setting 2 extends the caching to all textures - though Managed/Shared textures cannot be reused until after the frame in which they were released has been processed on the GPU. In this mode id<MTLTexture> objects are never returned to the OS so in order to conserve VRAM calls to setPurgeableState are made to allow the driver to reclaim unusued memory if required.

Also ensure that command-buffer failure is always fatal - there is no way to recover or continue if a command-buffer fails.

Lighting Scenarios and lightmaps moved to separate package
* Levels can be marked as lighting scenarios (eg Day, Night). Lighting is built separately for each lighting scenario with actors / lights in all other scenario levels hidden. Only one lighting scenario level should be visible at a time in game, and its lightmaps will be applied to the world.
* Most outputs of the lighting build now go into a separate _BuiltData package. This improves level Save and AutoSave times as the separate package will only be dirtied after lighting rebuilds.
* If a lighting scenario is present, all lightmaps are placed inside it's _BuiltData package. This means that only the currently loaded lighting scenario's lightmaps will be loaded (Day or Night, but not both). This also means that lightmaps for a streaming level will not be streamed with it.
* For backwards compatibility, existing lightmaps are moved to a new _BuiltData package on load.
* Reflection captures and precomputed visibility were not moved to the separate package. Reflection captures are force updated on load of a lighting scenario level, which can increase load times.

Speculative fix for UE-34815; have yet to repro this but there's really only so many things it could be. I currently don't see how the sim resources could go away after queueing, so I'm replacing the check with an ensure and null checking the resource pointer.

Change Apple RHI initialisation to select the first compatible shader platform to decide which RHI to initialise. Internally in MetalRHI we must gracefully fallback to a lower feature-level when this initial selection is not available on the current device/OS, in which case we need to validate that the selected shader platform was actually packaged. The order of initialisation is different per-platform:
On Mac: Order of initialisation is the order listed in TargetedRHIs .ini specifications.
On iOS/tvOS: Order is explicit: Metal MRT > Metal ES 3.1 > OpenGL ES 2

DR - Proper support for int defines
Change 3142519 on 2016/09/27 by Arne.Schober
DR - [UE-33438] - Added a Project Setting to enable Skincache Shader Permuations. The Default value for the Skincache mode was changed to enabled. The reasoning behind this was that it will be auto disabled when Skincache Shaders are disabled, and runtime toggle is a debuging feature that mainly programmers are dealing with. The Recompute Tangents option in the Skinned Mesh is now automatically grayed out when no Skincache Shader Permuations are available.

Change 3142762 on 2016/09/27 by Uriel.Doyon
Added per static mesh and per skeletal mesh UV density data. The data is now saved and available in cooked builds.
The density are computed by the engine but can be overridden by the user in the material tabs.
Texture streaming intermediate component data is now per material instead of per lod-section.
New ViewModeParam in FSceneViewFamily allowing context specific param per viewmode.
This is currently used to show which UV channel and which texture index is being
shown in the texture streaming accuracy viewmodes.
This replaces r.Streaming.AnalysisIndex
Renamed texture streaming viewmodes:
MeshTexCoordSizeAccuracy -> MeshUVDensityAccuracy
MaterialTexCoordScalesAccuracy -> MaterialTextureScaleAccuracy
MaterialTexCoordScalesAnalysis -> OutputMaterialTextureScales
Improved UV density computation and viewmode.
LightmapUVDensity is now computed separately from UVChannel Density.
Fixed texture streaming for instanced static mesh component and derived types.

DumpUnbuiltLightIteractions after lighting build for debugging
Change 3143822 on 2016/09/28 by Arne.Schober
DR - Refactoring of the ViewMatrices. Moved the Derived Matrices into the FViewMatrix struct. Made all members private do emphasize the static constness of that struct after creation. Renamed the heavy weight members on this struct to Compute*. Methods that modify The ViewMatrices have been renamed to Hack* to discurage their use in the future until a better solution for those problems is found. The ViewMatrix modification is especially misleading because it only changes the State of the ViewMatrices to read their Position from the Material Editior as if coming from the Lightsource (mainly for manual bilboards) as well as doing someting similar to generate CPU bilboards for shadows.

Improved "Repaired Painted Vertex Colors" log message. This is now done once on levels at load in the editor, instead of for every component (massive log spam). Total load time caused by the fixup is reported.

Moving wanted mip computation (according to budget) to async task.
Update "stat streaming" to show visible mips and also loading progression.
Fixed overly wanted mip issue cause be max range clamping.
Optimized cost of the texture streamer on the gamethread.
Character, Terrain and Forced Load are now loaded with priority in the AsyncIO
Reduced streaming temp memory requirements on PS4.
Async streaming task now runs in parallel to the incremental update.
Fixed bug with bProcessEverything not working as expected in UpdateResourceStreaming.
Fixed metrics with HiddenScale being applied in addition to overbudget limitation.
Improved budget stability when using split load request (one for visible mips + one for hidden mips)
Implemented a more agressive visibility test (used to be a seen in the last 5 sec, now closer to .5)
Streaming stats are now within a single class named FTextureStreamingStats and updated in a single function.
Cleanup of FStreamingTexture state update into a single function (UpdateDynamicData).
Retention logic now drops texture based on the last render time (for non visible textures) to reduce looping effects.
