Needed for upcoming MeshDecals
Change 2982601 on 2016/05/18 by Daniel.Wright
Movable skylight now matches stationary for subsurface shading models
* Two sided was broken in 4.11, Subsurface had never been handled
Change 2982603 on 2016/05/18 by Daniel.Wright

Better categories for some Rendering project settings
Change 2982619 on 2016/05/18 by Daniel.Wright
Scene capture 2d improvements
* Orthographic projection supported
* Opacity is now captured in alpha, allows partial rendering in a scene capture and compositing into another scene later
* Various GBuffer attributes are now available to be captured, including depth
* Changed Blueprint capture function to CaptureScene, which happens immediately (was previously deferred), allowing multiple captures with different parameters
Change 2982664 on 2016/05/18 by Daniel.Wright
Fading out planar reflections based on roughness since they don't have support for variable roughness (fade starts at .2 roughness, ends at .3)

Shorter display name for WorldPosition material node
Change 2984423 on 2016/05/19 by Daniel.Wright
Fixed WorldPosition and ScreenPosition for downsampled separate translucency by scaling SvPosition before those computations. The View uniform buffer still contains incorrect buffer sizes for this pass.
Change 2984432 on 2016/05/19 by Rolando.Caloca
DR - Disable PPCombineLUT for Vulkan to work around glslang issue (will need to be reenabled when adding SM4/5 path)
Change 2985415 on 2016/05/20 by Daniel.Wright

Making use of MATERIALBLENDING_ANY_TRANSLUCENT
Change 2989812 on 2016/05/25 by Daniel.Wright
Hide DFGI show flags from UI
Change 2989901 on 2016/05/25 by Daniel.Wright
Height fog now works properly in planar reflections
* The ray used for computing fog is first clipped by the reflection plane
Change 2989904 on 2016/05/25 by Daniel.Wright
Always use PF_FloatRGBA for LightAccumulation to guarantee alpha channel and negative range
Change 2989991 on 2016/05/25 by Daniel.Wright
Improved usability for DBuffer Decals
* 'Show Decals' works correctly, previously would fetch from uninitialized textures
* DBuffer being enabled forces a full prepass, previously decals would render incorrectly unless correct settings of r.EarlyZPass were used
* Improved the PrePass draw event to indicate whether it's full or partial
* Materials using DBuffer blend modes will fail to compile when the DBuffer project setting is disabled, instead of just being invisible
* r.EarlyZPass can now be changed at runtime, which is useful for profiling
Change 2990008 on 2016/05/25 by Daniel.Wright
Fixed capsule shadows on skeletal meshes with scaling
Change 2990274 on 2016/05/25 by Daniel.Wright
Fixed DFAO (from cl 2961310)
Change 2990304 on 2016/05/25 by Martin.Mittring
OR-22233 GPU Sprites invisible unless solo'd
#jira:OR-22233
Change 2990309 on 2016/05/25 by Martin.Mittring
Added SubDSurface actor (using CPU code of OpenSubDiv), component, asset as starting point for more work in that direction,
(Early work in progress)
Change 2990363 on 2016/05/25 by Daniel.Wright
Spreading precomputed visibility to neighbors now uses a 2d grid to find neighbors, speeds up the process for 800k cells from 40 mins to 20s
Change 2990392 on 2016/05/25 by Daniel.Wright
Added r.AOSpecularOcclusionMode, which determines how specular should be occluded by DFAO
0: Apply non-directional AO to specular.
1: (default) Intersect the reflection cone with the unoccluded cone produced by DFAO. This gives more accurate occlusion than 0, but can bring out DFAO sampling artifacts.
2: (experimental) Cone trace through distance fields along the reflection vector. Costs about the same as DFAO again because more cone tracing is done, but produces more accurate occlusion.
Change 2990454 on 2016/05/25 by Martin.Mittring
polish readme
Change 2990610 on 2016/05/25 by Martin.Mittring

#code_review:Shane.Caudle
Change 2990754 on 2016/05/25 by Zabir.Hoque
Fix compiler warning: C4456: declaration of 'NewStaticMesh' hides previous local declaration.
#CodeReview: Martin.Mittring
Change 2990801 on 2016/05/25 by Zabir.Hoque
Only allocate reflection capture cubemaps if we are actually doing a reflection capture. The old approach always allocated based on CVar and worked with a warning on D3D since if SRC was larger than the DST, the extra SRC area was dropped. New approach only allocates when necessary and is correctly sized everytime. Also hardened access to CVar and what users are allowed to set.
#CodeReview Marcus.Wassmer, Rolando.Caloca, Daniel.Wright, Martin.Mittring

DR - Allow toggling compute skin dispatch at runtime
- r.SkinCacheShaders Now enable the shaders and feature
- r.SkinCaching enables toggling at runtime
- r.SkinCache.BufferSize Sets the size in bytes of buffer for outputting
- Now uses 3 UAV buffers instead of one (avoid RenderDoc crashes)
#codereview Marcus.Wassmer, Martin.Mittring
Change 2803940 on 2015/12/15 by Marcus.Wassmer
Add r.PS4.AsyncComputeBudgetMode to switch between CUMasking and WaveLimit modes. So far it looks like WaveLimits behave better in UE4.
Also rearrange AsyncSSAO to run immediately after HZB to overlap with occlusion queries. In my testing this takes SSAO cost from .5ms -> .2ms. However it had to be hacked to run without normals. Hopefully Martin can get some real AsyncSSAO in.
#rb Martin.Mittring
#codereview Martin.Mittring
Change 2803999 on 2015/12/15 by Uriel.Doyon
Refactored the shader complexity material override logic to allow other viewmodes shader overrides.
TexelFactorAccuracy ViewMode : shows the accuracy of the static mesh texel factors, used for streaming.
WantedMipsAccuracy ViewMode : shows the accuracy of the static mesh wanted mips accuracy, used for streaming.
Added an option to stream textures based on the AABB distance instead of using the sphere approximation.
Added an option to only keep a the wanted mips.
Moved optimization related viewmodes into a submenu to avoid polluting the interface.

make separate translucency screen percentage a bit more robust; add numsamples to the render target creation functions in preparation for MSAA support for higher quality with low res separate translucency
#rb martin.mittring
Change 2804367 on 2015/12/15 by Daniel.Wright
Capsule shadow primitives are tracked separately on registration - saves 2.6ms of RT time doing the view frustum culling in a medium sized map
Change 2805293 on 2015/12/16 by Olaf.Piesche
logging if potentially immortal emitters are spawned from gameplay; this should catch if we spawn burst only emitters with indefinite life spans (muzzle flashes, hit impacts, etc.)

#test:editor
Change 2811205 on 2015/12/22 by Brian.Karis
Pulled clear coat out of the reflection compute shader. Added permutation for skylight.
Clear coat base layer now done in base pass. It only picks up the closest capture. This will cause popping when the object moves. Still needs a cross fade.

Added check for stale BP classes in FKismetCompilerUtilities::IsTypeCompatibleWithProperty() to stop compiler errors during reinstancing.
[UE-19795] - UMG Compiler error when adding variable to nested Widget
Change 2721474 on 2015/10/08 by Andrew.Rodham
Sequencer: Movie render operations now successfully capture UMG UI
Change 2724958 on 2015/10/12 by Chris.Wood
Added missing resource cleanup code to UMG widgets
[UE-21874] - UWIdget classes with missing ReleaseSlateResources() overrides
Added ReleaseSlateResources() to ListView, TileView and Slider widgets to reset shared pointers to slate widgets.
Change 2733562 on 2015/10/19 by Andrew.Rodham
Sequencer: Fixed spawnables not working in sub-sequences
- The issue here was that sequence track instance updates had no knowledge of which sub-sequence they were being evaluated within. We now pass the active sequence instance into the relevant track instance functions.
- Also addressed some issues to do with save/restore state not getting called correctly on master tracks of sequence instances
- Tidied up spawn track editor
Change 2735264 on 2015/10/20 by Chris.Wood
Improved Engine analytics handling for Editor and games
[UE-21892] - Improve how Engine analytics are handled for Editor and games
Changes:
Added Privacy section to Editor settings
Exposed editor analytics flag in Privacy options

Changed AreEditorAnalyticsEnable() to use new flag
Prevented analytics init when disabled by user
Sending event and shutting down analytics when user opts out
Add in-game project setting for anonymous game usage data
Renamed and moved bHardwareSurveyEnabled
Added message about exposing in-game setting to end users
Added anonymous GUID id for in-game analytics
Moved end user settings to global config (defaultengine.ini)
Placeholder loc text on new options for now, pending legal wording sign-off
Change 2735866 on 2015/10/20 by Max.Preussner
Async: Added ability to register an optional callback function that is executed when a Future completes
Change 2739793 on 2015/10/23 by Andrew.Rodham
Sequencer: Refined movie scene capturing to ensure frame accuracies are maintained
- Aborting an in-progress capture now gracefully terminates the process (through a remote session command) to ensure it still creates a valid video
- Level sequece movie capture will now pick up a corresponding level sequence in the world, and use that to capture with. A new actor will be spawned at runtime with the correct asset, should one not already exist.
- Made -nomovie actually work
- Refined how active movie captures are managed
- Added option to 'stage' a sequence before starting the capture. This feature will set the sequence on its first frame for the preroll, to ensure that PPP effects are allowed time to stabilize
Change 2744402 on 2015/10/28 by Max.Preussner

Upload crashes from CRC to Data Router
[UECORE-249] - Integrate Crash Report Client with the Data Router
Upload to Receiver still active as we are running both in parallel for now.
We now occlude Separate Transluceny by new Gaussian DOF.
Details: optimized one full res pass if GaussianDOF with SeparateTranslucency is used. NearDOF is now occlusing/hiding SeparateTransluceny which allows DOFVignette to work better and it seems more right in general. If Far and Near DOF is used with Gaussian DOF it now requires another half res setup pass and full res composite pass.
Added enum to allow for 3 custom colors if a texture is not bound.
[CL 2656232 by Martin Mittring in Main branch]
Consolidated the visible and hidden area meshes into a single class that can be used by all HMD clients
Some house cleaning
[CL 2648164 by Ryan Vance 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]
help text:
Defines in which order the nodes in the CompositionGraph are executed (affects postprocess and some lighting).
Option 1 provides more control, which can be useful for preserving ESRAM, avoid GPU sync, cluster up compute shaders for performance and control AsyncCompute.
0: tree order starting with the root, first all inputs then dependencies (classic UE4, unconnected nodes are not getting executed)
1: RegisterPass() call order, unless the dependencies (input and additional) require a different order (might become new default as it provides more control, executes all registered nodes

[CL 2322274 by Richard TalbotWatkin 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]
* 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
