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

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

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.

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.

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

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

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

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.

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 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 3207002 on 2016/11/21 by Ben.Zeigler
#jira UE-38799
Fix it so per-widget copy of widget tree and all widgets inside are properly transient, they were being cooked before but never accessed.
Fix case where non ClientOnly public objects nested instead ClientOnly objects would cook but fail to load, and add ensure to catch these cases in the future.
If the full outer chain isn't available, it can't be loaded anyway, and this finds issues at cook time instead of load time.
We should generally outlaw non-transient objects with transient outers, it does not do what people expect.

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)

Change 3127130 on 2016/09/15 by Mark.Satterthwaite
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))). This change defines the missing overloads as returns with regular casts.

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.

Metal validation layer fix: under Metal if there are no reads from the vertex stage-in buffers we should use the Empty vertex declaration, not the filter declaration, otherwise we have to bind a redundant vertex stream buffer to silence the validation layer.

Duplicate CL #3137164:
Add stats to track exactly how many command buffers are allocated and committed each frame to work out why Fortnite on AMD is hanging, which turns out to be because each texture update/reallocation ends up in its own command-buffer. This needs to be rethought to pack these into fewer command buffers with the same synchronisation requirements to minimise command-buffer splits but for now we'll just make the default sufficiently large that we shouldn't see the hang until the work is done. 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.

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

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.

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.

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.

MIGRATING FIX @ Request
Off by 1 error on reflection roughness calculation affecting 4.12. When I hoisted the max mip index i did a -1 on both sides(c++ & hlsl). This is the simplest hotfix. In 4.13 I'll remove the shader instruction and only do the "-1" in c++ this 1 less shader instruction.

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

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

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

Fixed SCW always exiting after compiling a long shader, now checks idle time starting from the end of the last compile task
Automated smoke tests aren't run in standalone programs which are frequently launched as they increase the startup time (doubles startup time of SCW as shown in sampling profile)

Change 2772471 on 2015/11/18 by Daniel.Wright
Particle SubUV cutouts
* A new asset type 'SubUV Animation' precomputes bounding geometry for every frame of a SubUV texture animation.
* Particle emitters with a SubUV module can then use this SubUV Animation to render with much tigher bounding geometry to reduce overdraw.
* GPU performance savings depend on how much empty space (zero alpha) existed in the texture. Measured a reduction of 2-3x GPU time on a smoke effect.
* This only works if the material does not modify opacity to reveal areas with zero texture alpha

MAJOR FEATURES + CHANGES
==========================
Change 2733540 on 2015/10/19 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream
Capsule shadows
* Capsule shadows excel at extremely soft area shadows caused by a large light source angle, but don't support accurate self-shadowing
* Artists can setup a physics asset containing Spheres and Sphyls (capsules) for a skeletal mesh that will be used to represent the mesh's occlusion
* These shapes can then be used for direct shadowing (bCastCapsuleDirectShadow) on a skeletal mesh component, whose softness depends on the light source angle / radius
* The shapes can also be used to create an indirect shadow (bCastCapsuleIndirectShadow), whose direction and softness is derived from the precomputed sky occlusion (stationary sky light) or primary indirect lighting (static sky light)
* Capsule shadowing is computed at half res and uses tiled deferred culling for efficiency - only implemented for PC SM5 + PS4 so far
* Shadowing of movable skylights is not yet supported
Change 2735460 on 2015/10/20 by Uriel.Doyon@uriel.doyon_office_data
Basepass drawlist are now merged within a single drawlist.
Lighting policy parameters are now accessed through a uniform buffer.
Changed the global resource initialization so that InitRHI now comes before InitDynamicRHI
#codereview nick.penwarden
Change 2744741 on 2015/10/28 by Nick.Penwarden@nickp_streams
Remove unused RHI methods:
RHIIsDrawingViewport
RHIGpuTimeBegin
RHIGpuTimeEnd
Made default/empty versions of these calls and removed stubs from RHIs that don't use them:
RHISuspendRendering
RHIResumeRendering
RHIIsRenderingSuspended
Change 2745714 on 2015/10/28 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream
Lighting channels - each component and light can choose from 3 channels
* Primitives output their channel mask to stencil during the base pass, the masks are copied to a texture after the base pass, deferred lighting passes compare the primitive mask against the light's mask
* Dynamic shadow casting also respects the channels
* Only works on opaque materials, direct lighting, dynamic lighting
* Not implemented for tiled deferred atm
* This will replace CastsShadowsFromCinematicObjectsOnly in the future

Removed a lot of complexity of the skeletal mesh motionblur code (better for multithreading, simpler, faster) but going from one large buffer to per mesh buffers. Upload of bones only needed once.
* GPUSkinCache didn't even work before (in this branch)
* tested BasePass velocity
* tested split screen
* tested editor pause
* matinee camera cut (no need, invalidates velocity)
* tested CPU Skin? (never has motionblur)
* tested CreateSceneProxy (recreation is prevented in CreteSceneProxy unless bone count changes)
* test ES2 -featureleveles2

Change 2752766 on 2015/11/03 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream
Lightmass solver quality improvements
* IndirectLightingScale is no longer applied to photons, avoids splotchy artifacts when using small scales
* New 'Lightmass Portal' actor / component which tells the solver where to look for significant lighting. When lighting with a Static Skylight only, in a mostly indoor environment, setting up these portals is the only way to get high quality.
* Skylight bounce lighting is now much more accurate and leverages adaptive sampling
* Fixed a bug that effectively disabled adaptive sampling on high IndirectLightingQualities
* Shadow penumbras are also improved by IndirectLightingQuality
* Texel debugging is now a cvar 'r.TexelDebugging', instead of requiring a full recompile

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

[CL 2761339 by Nick Penwarden in Main branch]
* This fixes the bug where many unbuilt interactions during registration would get corrected by blueprint construction scripts but the stationary light would continue to think it was built
[CL 2496244 by Daniel Wright in Main branch]
* bCastShadowsFromCinematicObjectsOnly on the light
* bCastCinematicShadow on components
* Useful for limiting cinematic spotlight shadow cost
* These do not affect static shadowing or Ray Traced Distance Field shadows
[CL 2466535 by Daniel Wright in Main branch]
New primitive component setting bAffectDistanceFieldLighting, useful for grass whose instance count overwhelms DFAO
Distance field volume texture allocations are sorted by size for better packing, and atlas is repacked on texture reallocation
[CL 2368153 by Daniel Wright in Main branch]
* Support for point, spot and directional lights
* LightSourceRadius / LightSourceAngle controls how large the penumbras are, with proper sharp contacts
* Directional lights use fast scatter culling path, the others use tiled gather culling
* Local lights only operate on the screen bounding rect
[CL 2302917 by Daniel Wright in Main branch]
* Provides mid-range stable AO for dynamic rigid meshes
* Movable sky lights are now supported, and distance field AO is used for shadowing Movable sky lighting from dynamic scenes
* Static meshes are preprocessed into signed distance field volumes at mesh build time when the r.AllowMeshDistanceFieldRepresentations project setting is enabled
* Non-uniform scaling does not work with this method (mirroring is fine), animating through world position offset also causes artifacts as the two representations diverge
* Occlusion is computed along cones to reduce over-shadowing, object distance fields are operated on directly (no hierarchy) to obtain enough resolution to prevent leaking, visibility traces are done with cone stepping to allow better parallelization, and shading is done adaptively in space and time using the surface cache.
