Change 3055495 on 2016/07/19 by Marc.Olano
Allow Noise material node on mobile
No reason to exclude mobile, except for Fast Gradient Noise, which uses 3D textures. Allow this node on ES2 for all of the other noise functions.
#jira UE-33345
Change 3055602 on 2016/07/19 by Luke.Thatcher
Fix crash bug in D3D11 RHI when selecting adapters.
- Array of adapter descriptors will get out of sync with the adapter index if any adapter is skipped (e.g. the Microsoft Basic Render Device).
#jira UE-33236
Change 3055890 on 2016/07/19 by Daniel.Wright
Improved the assert in LoadModuleChecked so we won't have to check the log to see which module it was
Change 3055891 on 2016/07/19 by Daniel.Wright
Fixed Global Distance Field not dirtying previous object position on UpdateTransform - left behind a phantom shadow on teleports

Change 3055892 on 2016/07/19 by Daniel.Wright
Higher poly light source shapes drawn into reflection captures
Change 3055893 on 2016/07/19 by Daniel.Wright
More info to 'Incompatible surface format' GNM assert
Change 3055904 on 2016/07/19 by Daniel.Wright
Reflection environment normalization improvements
* Indirect specular from reflection captures is now mixed with indirect diffuse from lightmaps based on roughness, such that a mirror surface will have no mixing. Reflection captures now match other reflection methods like SSR and planar reflections much more closely.
* When a stationary skylight is present, Reflection captures are now normalized as if the initial skylight will always be present, giving consistent results with static skylight reflections. The skylight and reflection captures with sky removed used to be normalized separately, compacting the relative brightness between the sky and scene.
* Added r.ReflectionEnvironmentLightmapMixing for debugging lightmap mixing issues. This toggle was previously not possible due to prenormalizing the capture data.
* The standard deferred reflection path (r.DoTiledReflections 0) can no longer match the results of the compute path or base pass reflections, as it would require MRT to accumulate the average brightness
* Removed unused r.DiffuseFromCaptures
* Cost of reflection environment on PS4 increased from 1.52ms -> 1.75ms with this change, but decreased back to 1.58ms by reducing tile size to 8x8
Change 3055905 on 2016/07/19 by Daniel.Wright

Change 3062244 on 2016/07/22 by Daniel.Wright
Discard old prenormalized reflection environment data on load
Change 3062283 on 2016/07/22 by Daniel.Wright
MSAA support for the forward renderer
* AntiAliasing method is chosen in Rendering project settings, DefaultSettings category
* Deferred passes like shadow projection, fogging and decals are only computed per-pixel and can introduce aliasing
* Added Rendering project setting VertexFoggingForOpaque, which makes height fog cheaper and work properly with MSAA
* The AntiAliasing method in PostProcessSettings has been removed, this may affect existing content
* Added r.MSAACount which defaults to 4
* Integrated wide custom resolve filter from Oculus renderer, controlled by r.WideCustomResolve
* GBuffer targets are no longer allocated when using the forward renderer
* Decal blend modes that write to the GBuffer fall back to SceneColor emissive only
Change 3062666 on 2016/07/23 by Uriel.Doyon
Added legend to streaming accuracy viewmodes
Added a new helper class FRenderTargetTemp to be reused in different canvas rendering.
Exposed the pass through pixel shader so that it can be reused.

Clamping noise tessellation for beams at a high but sensible value; also making sure during beam index buffer building that we never get over 2^16 indices; this is a bit hokey, but there are so many variables that can influence triangle/index count, that this is the only way to be sure (short of nuking the entire site from orbit).

Reduced streaming temp memory requirements on PS4.
Async streaming task now runs in parallel to the incremental update.

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.

Texture streaming build now takes into account the material texcoord scales applied to the texture sampling.
Also finds out which texcoord is being used when sampling textures (between 0 and 3 currently).
TexCoord analysis debug view shaders is now working with SM4 ane SM5.
StaticMeshComponents hold persistent data coming from the texture streaming build.
#tests tested with different Paragon assets. Editor SM4 & SM5. Cooked maps

Planar reflections
* New actor and component
* The scene is rendered to texture with a mirrored camera and a clip plane each frame
* The reflection texture is then applied to opaque pixels in a deferred pass, with distance and angle from plane fades
* Translucent materials apply the nearest reflection plane in the base pass
* Planar reflections require the project setting 'Support global clip plane for Planar Reflections' to be enabled, since writing to SV_ClipDistance all the time adds about 15% BasePass GPU time on PS4
* Fixed global distance field in materials which had been broken since moving global distance field properties into the view uniform buffer
* Fixed PS4 removing system-value semantics when output from vertex shader and not read in next stage

DR - Initial fix for canvas locking inside a render pass
[CL 2932649 by Gil Gribb in Main branch]
Instead of rendering a full screen quad for post process passes, render a mesh which represents only the screen area visible in the HMD after distortion.
This cuts the cost of post processing ~10-15% with no visible difference.
Initial implementation for the Vive.
[CL 2644327 by Ryan Vance in Main branch]
This feature buidls a stencil buffer according to the rougness in the GBuffer to make the difference between pixels that need a SSR computation and those who don't, instead of an early return in the SSR shader itself. Therefore SSR pixel shader invocations will only be for pixel that needs on hardware that have a high resolution stencil test before the pixel shader invocations packing into front lines, removing the efficiency drop caused by the thread that might early return in front lines that still have at least one thread that didn't early return.

HZB is now always built and stored on ViewInfo.
SSR uses constant depth intersect instead of segment intersect for better quality near contacts.
[CL 2402625 by Brian Karis in Main branch]
- Removed default shader platform parameter from GetGlobalShaderMap()
- Added an inline overload of GetGlobalShaderMap() that takes a feature level instead, and translates to the correct shader platform
- Cached feature level on FSceneView for faster access
- Cached shader map on FViewInfo for faster access
- Cached featurelevel/shadermap on rendering composition graph execution context, for faster access
Fixed a couple of crashes when switching feature level dynamically
- Needed to allow certain shader permutations to be generated if feature level was ES2, but still on a PC platform. (i.e. hitproxy shaders, and basepass shaders used by editor primitives system)

* Both paths still exist in code during this transition. The GetDynamicMeshElements path is currently disabled, enable with 'r.UseGetDynamicMeshElements 1'.
* DrawDynamicElements was called once per pass, all sorts of pass-specific cruft had leaked in along with short-term modifications of shared structures (vertex factories and material proxies). DrawDynamicElements was not const, so a bunch of 'update' type work had leaked in. Various PreRenderView implementations relied on the view being in the view family.
* GetDynamicMeshElements is called once in InitViews, and the resulting meshes are used in various passes. GetDynamicMeshElements is const and must not modify the proxy, update work should be pushed to the proxy from the game thread. GetDynamicMeshElements can be called on views that are not in the view family, which allows a proper view for shadow depth passes.
* View mode override functionality moved out of the individual proxies into a centralized place, ApplyViewModeOverrides
* GPU particles not working yet, FRecastRenderingSceneProxy not implemented
