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 3122544 on 2016/09/13 by Ben.Woodhouse
Shadow stencil optimisation with cvar (enabled by default)
Avoids redundant clearing the stencil buffer for per-object and pre shadows by zeroing the stencil during testing, following discussion on UDN.
This means we don't benefit from Hi Stencil on GCN for the shadow projection draw calls, but it's still faster in all the cases I could find, including for the player character where the bounding box is quite large. (Note: early stencil still works fine, according to PIX)
Shadow projection GPU time profiling :
Test map with 35 characters, stationary directional light
- 4ms-2ms on XB1
- 2.5ms to 0.9ms on PC (r9-390X)
- 3ms-2ms on PS4
Paragon PS4 (roughly 20% reduced - from ~0.39ms)

DR - [UE-34481] - Extract all the State which is necessary to execute the DebugTextDrawingDelegate from the SceneProxy into its own Helpers to be drawn to the canvas later on.

Change 3127130 on 2016/09/15 by Mark.Satterthwaite
Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))). This change defines the missing overloads as returns with regular casts.

Fix for ensure fail when initializing point light shadowmaps.
This came about because cubemap rendertargets always have Extents of (Resolution, 0). The Y component was implicitly used to determine if it was a cubemap, which is odd... The fix was to make the definition explicit via a flag and initialize both the X and Y parameters.
I suspect the ensure started happening recently due to a more recent change, but fixing the underlying logic seems like the correct fix.

Change the ShaderCache to not cache resource bindings in the draw states for shader platforms that don't care - reduces the number of draw states considered significantly without reducing effectiveness.

Change 3131625 on 2016/09/19 by Mark.Satterthwaite
Inside MetalRHI add an optional cache for disposed texture objects so we may reuse them - controlled by CVAR rhi.Metal.TextureCacheMode which must be set prior to running as it can't be changed at runtime. Settings: 0 = off, 1 (default) = will attempt to reuse private memory texture objects within the frame they are released otherwise they are disposed of as before. Setting 2 extends the caching to all textures - though Managed/Shared textures cannot be reused until after the frame in which they were released has been processed on the GPU. In this mode id<MTLTexture> objects are never returned to the OS so in order to conserve VRAM calls to setPurgeableState are made to allow the driver to reclaim unusued memory if required.

Add stats to track exactly how many command buffers are allocated and committed each frame to work out why Fortnite on AMD is hanging, which turns out to be because each texture update/reallocation ends up in its own command-buffer. This needs to be rethought to pack these into fewer command buffers with the same synchronisation requirements to minimise command-buffer splits but for now we'll just make the default sufficiently large that we shouldn't see the hang until the work is done. Also ensure that command-buffer failure is always fatal - there is no way to recover or continue if a command-buffer fails.

Lighting Scenarios and lightmaps moved to separate package
* Levels can be marked as lighting scenarios (eg Day, Night). Lighting is built separately for each lighting scenario with actors / lights in all other scenario levels hidden. Only one lighting scenario level should be visible at a time in game, and its lightmaps will be applied to the world.
* Most outputs of the lighting build now go into a separate _BuiltData package. This improves level Save and AutoSave times as the separate package will only be dirtied after lighting rebuilds.
* If a lighting scenario is present, all lightmaps are placed inside it's _BuiltData package. This means that only the currently loaded lighting scenario's lightmaps will be loaded (Day or Night, but not both). This also means that lightmaps for a streaming level will not be streamed with it.
* For backwards compatibility, existing lightmaps are moved to a new _BuiltData package on load.
* Reflection captures and precomputed visibility were not moved to the separate package. Reflection captures are force updated on load of a lighting scenario level, which can increase load times.

Speculative fix for UE-34815; have yet to repro this but there's really only so many things it could be. I currently don't see how the sim resources could go away after queueing, so I'm replacing the check with an ensure and null checking the resource pointer.

Change 3142262 on 2016/09/27 by Mark.Satterthwaite
Change Apple RHI initialisation to select the first compatible shader platform to decide which RHI to initialise. Internally in MetalRHI we must gracefully fallback to a lower feature-level when this initial selection is not available on the current device/OS, in which case we need to validate that the selected shader platform was actually packaged. The order of initialisation is different per-platform:
On Mac: Order of initialisation is the order listed in TargetedRHIs .ini specifications.
On iOS/tvOS: Order is explicit: Metal MRT > Metal ES 3.1 > OpenGL ES 2

DR - Proper support for int defines
Change 3142519 on 2016/09/27 by Arne.Schober
DR - [UE-33438] - Added a Project Setting to enable Skincache Shader Permuations. The Default value for the Skincache mode was changed to enabled. The reasoning behind this was that it will be auto disabled when Skincache Shaders are disabled, and runtime toggle is a debuging feature that mainly programmers are dealing with. The Recompute Tangents option in the Skinned Mesh is now automatically grayed out when no Skincache Shader Permuations are available.

Change 3142762 on 2016/09/27 by Uriel.Doyon
Added per static mesh and per skeletal mesh UV density data. The data is now saved and available in cooked builds.
The density are computed by the engine but can be overridden by the user in the material tabs.
Texture streaming intermediate component data is now per material instead of per lod-section.
New ViewModeParam in FSceneViewFamily allowing context specific param per viewmode.
This is currently used to show which UV channel and which texture index is being
shown in the texture streaming accuracy viewmodes.
This replaces r.Streaming.AnalysisIndex
Renamed texture streaming viewmodes:
MeshTexCoordSizeAccuracy -> MeshUVDensityAccuracy
MaterialTexCoordScalesAccuracy -> MaterialTextureScaleAccuracy
MaterialTexCoordScalesAnalysis -> OutputMaterialTextureScales
Improved UV density computation and viewmode.
LightmapUVDensity is now computed separately from UVChannel Density.
Fixed texture streaming for instanced static mesh component and derived types.

DumpUnbuiltLightIteractions after lighting build for debugging
Change 3143822 on 2016/09/28 by Arne.Schober
DR - Refactoring of the ViewMatrices. Moved the Derived Matrices into the FViewMatrix struct. Made all members private do emphasize the static constness of that struct after creation. Renamed the heavy weight members on this struct to Compute*. Methods that modify The ViewMatrices have been renamed to Hack* to discurage their use in the future until a better solution for those problems is found. The ViewMatrix modification is especially misleading because it only changes the State of the ViewMatrices to read their Position from the Material Editior as if coming from the Lightsource (mainly for manual bilboards) as well as doing someting similar to generate CPU bilboards for shadows.

MAJOR FEATURES + CHANGES
==========================
Change 3079316 on 2016/08/05 by Ben.Marsh
Better PCH selection in ShaderFormatOpenGL and MetalShaderFormat - make sure Core is the first included header.
Change 3080579 on 2016/08/08 by Ben.Marsh
Slate: Move DEBUG_TAB_MANAGEMENT into SDockingTabStack.h to remove circular include dependency with DockingPrivate.h.
Change 3080587 on 2016/08/08 by Ben.Marsh
StandaloneRenderer: Move platform includes into a separate header so we can make individual headers self-contained, without having a circular dependency on StandaloneRendererPrivate.h.
Change 3080789 on 2016/08/08 by Ben.Marsh
Move BuildGraph tasks for chunking, posting builds, labeling builds, and merging manifests into the MCP project. While we do provide public interfaces for this functionality, we don't currently expect anyone outside Epic to be using them.
Change 3080815 on 2016/08/08 by Ben.Marsh
BuildGraph: Add a -GenerateDocs option, which writes out an HTML file constructed from C# XML documentation containing all the task information.
Change 3081374 on 2016/08/08 by Ben.Marsh
UBT: Invalidate the makefile if any UHT headers are deleted. Should fix issue where files are moved from one module to another, and the original module no longer contains any generated headers. Its include path needs to be removed from the compile environment.
Change 3083152 on 2016/08/09 by Ben.Marsh

UBT: Specify the -precompile option when generating project files for a target, so we include all valid modules for intellisense.
Change 3085594 on 2016/08/11 by Ben.Marsh
Change modules which reference a public header for their PCH to use a private PCH instead, even if it just includes the public header for now.
Change 3085999 on 2016/08/11 by Ben.Marsh
Add some missing #pragma once directives.
Change 3086146 on 2016/08/11 by Ben.Marsh

Change 3086172 on 2016/08/11 by Ben.Marsh
Fixup some C-style header guards to use #pragma once instead.
Change 3087289 on 2016/08/12 by Ben.Marsh
Split out UPackage and UMetaData into their own headers (they're already implemented in separate CPP files)
Change 3087310 on 2016/08/12 by Ben.Marsh
Move method stubs for FNullSlateSoundDevice into a CPP file, since they're exported from the SlateCore module.
Change 3087341 on 2016/08/12 by Ben.Marsh
UdpMessaging: Move PCH before #if PLATFORM_DESKTOP; it will only be defined if the definition is included.
Change 3087457 on 2016/08/12 by Ben.Marsh
Core: Reorganize the FTransform and FMatrix headers: Transform.h now includes TransformNonVectorized.h or TransformVectorized.h as appropriate, and UnrealMatrix.h is now Matrix.inl (and included from Matrix.h).
Change 3088407 on 2016/08/13 by Ben.Marsh
Replace use of Windows SIZE_T define with the regular C++ size_t.
Change 3088416 on 2016/08/13 by Ben.Marsh
Include a header from all .generated.cpp files (GeneratedCppIncludes.h) which includes all the basic types required to compile them, rather than assuming that the module PCH will include everything.
Also include the real declarations of noexport classes in Object.h (now renamed to NoExportTypes.h for clarity) when the CPP macro is defined, so the .generated.deps.h file will automatically have the correct definitions for them at compile time rather than relying on them being in the private PCH.
Finally, rename UObject.h to Object.h for consistency with the naming convention for all other UObject classes. UObject.h still exists for now, but outputs a deprecated message if included.
Change 3088544 on 2016/08/14 by Ben.Marsh
Core: Move the definition of the TEXT() macro into Platform.h, to avoid having to include OS headers to get it.
Change 3088552 on 2016/08/14 by Ben.Marsh
Fix compile errors for some modules that don't already include CoreUObject.h.
Change 3088925 on 2016/08/15 by Ben.Marsh

D3D12RHI: Move around some implementations to fix circular header dependencies which are masked by delayed template instantiation.
Change 3090303 on 2016/08/16 by Ben.Marsh
Engine: Add a template specialization for TPointerIsConvertibleFromTo<AActor, const volatile UObject> to fix dependency on complete AActor definition for static assert in TWeakPointer<AActor>, which only appears if including Level.h without Actor.h. Delayed template instantiation usually masks this issue.
Change 3091861 on 2016/08/17 by Ben.Marsh

UETOOL-213 - Minimize Slate FString -> FText conversion (remove SLATE_TEXT_ATTRIBUTE)
This fixes any editor/engine specific code that was passing text to Slate as FString rather than FText.
[CL 2399803 by Jamie Dale in Main branch]
* Moved Slate.h into SlateBasics.h and began shifting less commonly used headers into SlateExtras.h.
* Slate.h now simply includes SlateBasics.h and SlateExtras.h.
* Slate.h includes a deprecated warning now to indicate that SlateBasics.h + specific includes should be used instead.
* Moved dozens of inlined functions using Slate widgets into .cpp files to avoid header dependencies.
* All code samples now include SlateBasics.h and SlateExtras.h so future shifts will not break most those projects, but not trigger the deprecation warning of including Slate.h.
