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

Change 3232641 on 2016/12/13 by Mark.Satterthwaite
- Eliminate redundant state changes in MetalRHI in the state cache.
- Add a new debug level for setting buffers to nil prior to calls to set*Bytes so that the tool doesn't display incorrect data.
- Make testing for validation & statistics features use the same EMetalFeatures API as everything else for consistency.
- Cache the fallback depth-stencil texture in the state cache and ignore it for determining whether a pass can restart - if we are using this texture its contents are worthless anyway.

Fix 10.11.6 support (aka -nometalv2): the stencil view workaround necessitates a mid-render blit and the way things were setup resulted in the HasValidRenderTargets assert firing. Refactored the code to separate the concept or valid render-states in the cache from active render-states in the render-pass. Now it works as intended and will be needed for 4.15.

Change 3237394 on 2016/12/15 by Mark.Satterthwaite
Add Metal-specific permutations of TBasePassHS - they affect the C++ definition on all platforms but are only cached or used on Metal - because the way we compile the combined VS+HS tessellation stage requires that the combined VS + HS HLSL code references the same resources, otherwise we get incorrect resouce bindings and subsequently fail to render properly. Long-term the Metal tessellation code will need to be refactored so that the vertex shader stage is emitted as a separate shader from the hull shader stage as this but will keep cropping back up and continue to complicate the engine.

Disable timestamp queries on pre-Maxwell nvidia hardware. Local testing suggests that this is the major cause of instability in the UE4.14 release.
It's possible that we could be more targeted by only excluding Fermi and older hardware, but identifying fermi hardware by device ID is difficult in practice, since the range overlaps with Kepler.

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.

Fix for decal rendering resource leak
The cause was that FD3D11BoundRenderTargets doesn't support setting RTs sparsely. So if one element is NULL, it won't release the ones after it.
The sparse RT layout happened as a result of a change back in October, which meant that GBuffers for decals could be set sparsely, dependent on whether the decal wrote to the normalbuffer
This change adds support for sparsely bound rendertargets in FD3D11BoundRenderTargets.

Forward renderer initial implementation
* Point and spot lights are culled to a frustum space grid, base pass loops over culled lights.
* Light culling uses a reverse linked list to avoid a per-cell limit, and the linked list is compacted to an array before the base pass.
* New cvars to control light culling: r.Forward.MaxCulledLightsPerCell, r.Forward.LightGridSizeZ, r.Forward.LightGridPixelSize
* A full Z Prepass is forced with forward shading. This allows deferred rendering before the base pass of shadow projection methods that only rely on depth.
* Dynamic shadows are packed based on the assigned stationary light ShadowMapChannel, since stationary lights are already restricted to 4 overlapping.
* GBuffer render targets are still allocated
* Fixed several issues in parallax corrected base pass reflections - not blending out box shape, discontinuity in reflection vector, not blending with stationary skylight properly
* Forward shading is now used for TLM_SurfacePerPixelLighting translucency in the deferred path
* Notable missing features: shadowing of translucency, support for various translucency lighting modes, multiple blended reflection captures

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.
This change also makes the CSM naming consistent with what the setting actually does (the old setting was named r.shadow.csm, although it affects per-object shadows as well as CSMs).

MAJOR FEATURES + CHANGES
==========================
Change 2975196 on 2016/05/12 by Robert.Manuszewski
Garbage Collector will no longer be responsible for generating class token stream, instead the token stream will be generated on startup or when a class has finished loading.
- This way we can avoid very long GC times after new blueprints have been loaded.
- Temporarily enabled CLASS_TokenStreamAssembled check in development builds (for testing purposes)

Change 2982106 on 2016/05/18 by John.Mahoney
Fixed a crash caused by loading two stat capture files simultaneously in the profiler.
If the user tries to load a capture file while another load is in progress, the previous load is now cancelled and cleaned up before proceeding with the new load.
Made the delegates in FNewStatsReader explicitly specify which profiler instance they are loading data for, instead of relying on the current value of LoadConnection->InstanceId.
This also fixes a crash that occurs when selecting a different capture file in the "Stats dump browser" pane of the profiler (after using Load Folder) while another file is still loading.
Cleaned up some weak pointer usage in the profiler window.

Harden MaterialParameterCollection from ending up with duplicate parameter names of GUIDs.
#Tests: Ran debug editor, create materail param collection with >500 elements. Still only ~18ms. Used param in shader.

#UE4 - JsonObjectConverter changes
- added the ability for a UStruct to emit json as a string if type traits are setup with ExportTextItem / ImportTextItem
- allows the UStruct to convert to json as something other than FJsonValueObject
-- things like FColor, FDateTime but they are already handled differently
- checked for possible change in existing behavior, no classes currently use type traits for this that aren't handled special already
- FUniqueNetIdRepl can now convert to/from json as a string

[CL 2856676 by Andrew Grant in Main branch]
- New filter flags in automationtest.h
- Compile time errors if proper flags are not specified
- Existing tests converted to new flags
- New "disabled" flag
- Filter dropdown in automation UI replaces Smoke Tests button
- Automation features are no longer compiled out in Test configuration at runtime (except in Shipping)
- Enabled automation tests to be triggered from in-game console in non-editor builds (automation controller is enabled)
NOTE: This will force licensees who use automation to update their tests.

- Events
Events work by writing to a preallocated buffer exposed to the VM as "SharedData". The underlying data storage for these is the same as particle attriubtes. Each "Shared Data" view in the VM has a counter which is incremented or decremented to aqcuire and consume a slot in this buffer for any particle that wished to write or read from it.
In the graph, this is done via ReadEvent and WriteEvent nodes. Each lets the user define the data they wish to read or write, just like for particle attributes.
Each also has a mandatory "Valid" pin which indicates whether the data being read or written is valid.
e.g.
A write would be marked deliberately valid or invalid by the user to control which particles write out event data. Valid <= 0.0f means dont' write. Valid > 0.0f means do write. Matches current working of less than etc. Should probably change to use ints when they're supported.
A read would be valid or not depending on whether there is data available in the event buffer.
Events TODO:
Once ints are supported, alot more power can be had using direct indexing of the buffers.
This leads me onto supporting generic, non-event buffers. Should be very easy to do.
Much of the VM support is hacked in and will want to be replaced after scalarization.
I may also move away form a "Shared Data" area and write a more general array feature. Couldn't really do this initially with no int support. Should have really done scalarization+int support first.
Needs BP interface.
** SECONDARY FEATURES **
- VM Debugger working - Still basic and rough. Allows a single particle to be traced through the VM for it's lifetime.
- Function Merging changes - Merged as needed during compiler traversal rather than all at start.
- Constatnt changes - Splat scalars when building table, not runtime. Faster and reduced code complexity.
- Fixed reallocation of niagara node pins so that existing connections are preserved.
- Added a reregister context class to reregister all niagara components that use a particualr script when that script is recompiled. TODO: Should also do this for property changes in the editor I think.
- Implemented GreaterThan Op. The reverse of LessThan
- Implemented VectorSelect Op. > 0.0f Selects input A, otherwise B.
- Added a new Graph Editor Tab to the Niagara Graph Editor. "Flattened Graph" shows you the scripts graph but with all the function calls merged into the main graph. Useful for debugging. Still a bit rough around the edges. Might not make it to V1.0 of niagara but useful for the moment.
** MINOR FIXES **
Fixed crash in Dev UI in the effect editor.
Tweakd the details customization for the dev ui.
Fixed leakage of all effect instances that were created. This stuff still needs some work. Need to do a pass over the high level stuff in Niagara and more carefully define lifetimes and ownerships.

This arranges all emitters in an SDetailView with some customization.
Primary benefit of this is that hooking things into the UI will require almost no work and elements can still be customized for a good UX.
Previous UI is still available and should work exactly as before.
Quite a bit of refactoring was needed to acheive this but much of it was needed for other things anyway and/or has some nice additonal benefits.
E.g.
- All constant types are supported easily.
- You can now create a default data object in the graph which will propagate through to the effect editor.
- Adding new data object types will be very easy.
Also added a delete and duplicate button for emitters in both UIs.
