Change 3232283 on 2016/12/13 by Ben.Woodhouse
D3D12 - downgrade root signature size warning to a log following a discussion with Microsoft. There's not much we can actually do about it, and it's not relevant to all hardware
#jira UE-36999
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.

Refactored HLOD texture streaming strategy to separate forced load from visibility.
Added an incremental update in the last stage of the texture streaming update load to clear any pending work.
Added an option "All" to the "BuildMateriaTexturelStreamingData" command to force rebuild everything.

DR - Fix for Vulkan drawing black
Change 3236788 on 2016/12/15 by Mark.Satterthwaite
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.

DR - Change more macros to lambdas
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.

Change 3237597 on 2016/12/15 by Ben.Woodhouse
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.

Distance field self shadowing controls for hiding world position offset self-shadow artifacts
* Removed static mesh build settings DistanceFieldBias, which shrunk the distance field, breaking AO and shadows
* Added DistanceFieldSelfShadowBias, which prevents occlusion close to the surface only, maintaining shadows on the ground and AO on the ground

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.

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)

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

DR - vk - Fixed crash when using vertex shaders with no descriptors
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
