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

Change 2746989 on 2015/10/29 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering
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
#rb: Rolando.Caloca
Change 2750734 on 2015/11/02 by Uriel.Doyon@uriel.doyon_office_data
Embree integration into Lightmass
Can be enabled through Lightmass.ini [DevOptions.StaticLighting]bUseEmbree.
Also [DevOptions.StaticLighting]bVerifyEmbree will compare ray casting results.
Only usable on Win64 with this submit.

Change 2752730 on 2015/11/03 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering
added SSAO CS version, can be enabled with

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
Change 2754018 on 2015/11/04 by Uriel.Doyon@uriel.doyon_office_data
Quad Complexity ViewMode (PCD3D_SM5 only).
Shader Complexity with Quad Overhead ViewMode (PCD3D_SM5 only). Require ShaderComplexity ViewMode & Show.Visualize.QuadOverhead
#review brian.karis
Change 2754760 on 2015/11/04 by Martin.Mittring@Martin.Mittring_Z3941_Dev_Rendering
improved SSAO quality (less high frequency noise) to avoid TemporalAA smearing
Change 2756308 on 2015/11/05 by Rolando.Caloca@rolando.caloca_T3903_S
DevRendering - Enable removing unused outputs on PS4 shader pipelines, disable by default removing unused on D3D (toggable with r.D3DRemoveUnusedInterpolators)
#codereview Marcus.Wassmer
Change 2757063 on 2015/11/06 by Simon.Tovey@Simon.Tovey_Dev

#github
#1614
Change 2757340 on 2015/11/06 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering
UE4 - Fixed the experimental r.RHICmdBalanceParallelLists 2 mode and renabled it for orion.
Change 2757343 on 2015/11/06 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering
UE4 - Added a path so that texture streaming can avoid flushing the RHI thread.
Change 2757985 on 2015/11/06 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream
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
#rb Rolando.Caloca
Change 2759058 on 2015/11/09 by Gil.Gribb@Gil.Gribb_Z2439_Dev-Rendering
UE4 - Dynamically set stream source to avoid creating a separate drawing policy for each static mesh with vertex colors.
#rb Daniel.Wright
Change 2760523 on 2015/11/10 by Uriel.Doyon@uriel.doyon_office_data

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)

[CL 2275937 by Graeme Thornton in Main branch]
* For several preview components (cascade + a couple of animation previews), don't create a separate FXSystem for the preview world. Just use the one created internally by the world
* Several bug fixes and improvements to dynamic feature level switch
* Continued conversion of code that references to global feature level.
