Change 3091951 on 2016/08/17 by Chris.Bunner
(Duplicate) CL 3090919: Fixed edge case interactions in HLOD ray rejection logic in Lightmass.
Change 3093162 on 2016/08/18 by Ben.Woodhouse
Fix minor memory leak (missing delete of RT Heartbeat thread)
Change 3093470 on 2016/08/18 by Ben.Woodhouse
Fix minor leak in FMonitoredProcess - the Thread member would get leaked if the FMonitoredProcess was cancelled, because it gets NULLed without deleting it. Fix is to add a bool to keep track of whether the thread is running, rather than using the Thread pointer.
Also fixes a race condition where the FMonitoredProcess::Thread member could get initialized after the thread had completed. This would cause IsRunning to never return false, even if the thread has completed, and the editor would hang on startup (this was fixed by setting bIsRunning to true before creating the thread)

Change 3094060 on 2016/08/18 by Daniel.Wright
Fully featured base pass reflection captures with blending and parallax correction
* Used in the forward renderer when materials opt-in to 'High Quality Reflections'
* Used in the deferred renderer for translucent 'Surface ForwardShading' materials
* Reflection captures are culled to a frustum space grid using the same reverse linked-list method as lights in the forward renderer
* Fixed grid culling in stereo / splitscreen
* The ReflectionEnvironment compute shader used in the deferred path also uses the culled grid now which reduces its cost from .93ms -> .70ms on 970 GTX. PS4 cost is about the same.
* Capsule indirect self-shadowing is now reduced in the forward path to match deferred, and both are controlled by r.CapsuleIndirectShadowSelfShadowIntensity
* SetupHZB is now skipped when SSAO / SSR / HZB are all disabled

Moving vertex factory dirtying to always happen in-editor for mesh emitters on dynamic data reinitialization; there are several cases in which this needs to happen (some material changes, mesh reimports...) which are difficult to track, so in-editor we just always recreate the mesh particle vertex factory with the dynamic data.

Change 3099173 on 2016/08/24 by Ben.Woodhouse
Fixed various issues with subsurface profile, for checkerboard and non-checkerboard code paths
- Re-enable non-checkerboard skin by default
- Checkerboard issues fixed:
- Emissive lighting was being applied twice due to not taking checkerboard pattern into account
- Emissive lighting was modulated by basecolor in the recombine
- Metallic materials were contributing specular lighting to the diffuse channel
- Non-checkerboard fixes:
- Fix write mask during SkyLightDiffuse so alpha is updated correctly
- Metallic specular lighting was broken (specularColor was lerping to white instead of baseColor)
- Optimisation: Fall back to default lit for pixels where the opacity is 0.
- For non-checkerboard, this gives better handling of metallic/emissive for pixels where SSS is not required (non-CB RGBA encoding for diffuse/spec doesn't cope well with colored specular or emissive)
- For checkerboard, this gives similar results in terms of shading, but we get full-resolution shading on non SSS pixels

Change 3073689 on 2016/08/02 by Ben.Woodhouse
Improved skin postprocess - support for full resolution, with diffuse/spec lighting combined into single RGBA (sharing chroma)
Full res lighting gives less temporal AA flickering, sharper diffuse and specular lighting in the surface (since this is now at full resolution), faster postprocessing if using a 64-bit rendertarget (on NV 980Ti).
Checkerboard rendering is controlled via the r.sss.checkerboard cvar. - 0 is off/full res, 1 is checkerboard, 2 is automatic based on scenecolor (non-checkerboard requires 64bit or more rendertarget w/separate alpha)
Tested/profiled on PC, PS4

Fix for UE-34241
Scene proxy ptr was being cached during a downcast.
Inside a call to CreateDynamicData, CheckMaterialUsage_Concurrent() was causing the scene proxy to be recreated an so the cached ptr was stale.
I've fixed the immediate issue but recreating the scene proxy here doesn't seem great. Maybe CheckMaterailUsage() should be rethought a bit.

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

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

Added a new helper class FRenderTargetTemp to be reused in different canvas rendering.

[CL 3072803 by Marcus Wassmer 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 is more correct for scanned textures as they include scattering already. Affects the look of emissive lighting (rarely needed and can be fixed by content). All diffuse lighting for SubsurfaceScatteringProfile is now done without the BaseColor (minor performance cost) and reading the Lighting before the SubsurfaceScattering pass would be different.
Removed the need for a SceneColor alpha channel as lighting is now stored in a checkerboard pattern for diffuse and specular separate. Specular and diffuse lighting on Subsurface materials can appear a bit less crips.
This means the use of 32bit SceneColor (for better performance) is now possible (we might change the defaults soon).
[CL 2640696 by Martin Mittring in Main branch]
- wasn't scaling right with ViewportSize, e.g. HighResScreenshot
- Missing a horizontal line in the 2d kernel
- Improved quality of the full res portion
- refactored to avoid one full res pass
- simplified Stereo rendering support
- In single viewport case it now goes down to 32bit texture format afterwards (input can be 32/RGB or 64/RGBA as before, without alpha it can look bad)

FORT-2471 Player character appears blurry with certain video settings
(Blurry is now only on Subsurface, there it could be a bit better using the non subsurface constribution as full res)
