MAJOR FEATURES + CHANGES
==========================

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 3122543 on 2016/09/13 by Ben.Woodhouse

	Override HasOcclusion for Widget3DComponentProxy to detect if the material is has depth testing enabled.

	#jira UE-35878

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)

Change 3125378 on 2016/09/14 by Arne.Schober

	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. The issue was that the SceneProxys are only owned by the RT after their creation and the GT should avoid reading from or writing state to them.

	#review-3125887 @brian.karis

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.
	#jira FORT-25869
	#jira UE-34263

Change 3127475 on 2016/09/15 by Rolando.Caloca

	DR - vk - Debug dump

Change 3128131 on 2016/09/16 by Ben.Woodhouse

	(Integrated from //UE4/Private-Partner-NREAL/...)

	Alpha output support for postprocess materials (optional via a parameter)

	Needed for end of frame compositing. Could be used to pass intermediate data from one blendable postprocess to another (e.g edge detection)

Change 3128135 on 2016/09/16 by Ben.Woodhouse

	GPU profiler (PS4) - remove bubbles between commandlist submissions from query times

	Use r.ps4.AdjustRenderQueryTimestamps cvar to enable/disable (defaults to on)

	Also fixes some potential precision issues with unit GPU timing

	#jira UE-36072

Change 3128759 on 2016/09/16 by Mark.Satterthwaite

	Back out changelist 3127130 - its causing a build failure in FPostProcessVelocityScatterVS because hlslcc is picking the wrong as_* overload.

	Improve vector noise tooltips & documentation

Change 3130547 on 2016/09/19 by Ben.Woodhouse

	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.
	#jira UE-35837

Change 3130578 on 2016/09/19 by Daniel.Wright

	Workaround OpenGL/NVidia bug with non-power-of-2 textures by disabling CSM atlassing if we're using OpenGL

	#jira UE-29332

Change 3130965 on 2016/09/19 by Arne.Schober

	DR - [UE-35679] - the crash was caused by the Resource of the UTexture being Null. And one of the Kismet Nodes calling a function on that resource. The solution was to disable that call from Kismet when only cooking.

Change 3130967 on 2016/09/19 by Chris.Bunner

	Hid redundant texture sampler properties from texture object parameter.
	Hid redundant texture property input on texture parameter nodes.
	Fixed copy-paste error in expression texture parameter docs.
	#jira UE-32724

Change 3131118 on 2016/09/19 by Mark.Satterthwaite

	Second attempt - this time with the correct input types. 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))).

	DR - Shrink gpu skinning permutations

Change 3131261 on 2016/09/19 by Mark.Satterthwaite

	Fix Metal validation failures due to particle rendering not binding buffers to all buffer inputs declared in the shader.
	ContentExamples Effects no longer aborts complaining that the particle system didn't bind a required buffer.

Change 3131265 on 2016/09/19 by Mark.Satterthwaite

	Fix FMetalDynamicRHI::RHIReadSurfaceData for shared textures on iOS.

Change 3131271 on 2016/09/19 by Mark.Satterthwaite

	Use private memory for the Metal stencil SRV workaround needed on El Capitan.

Change 3131273 on 2016/09/19 by Mark.Satterthwaite

	Disable the lazy-encoder construction in Metal for AMD - there is a situation that causes the lazy construction to perform a clear that isn't wanted and so far this hasn't been tracked down and fixed. Until then, this will render correctly.

Change 3131280 on 2016/09/19 by Mark.Satterthwaite

	For GLSL interpolation mode flags must come before storage mode flags and you can't redeclare the system variable gl_Layer to use a differing interpolation mode.

Change 3131283 on 2016/09/19 by Mark.Satterthwaite

	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. We can support ShaderCache with Metal SM5 but not the RHI thread enabled so change when we enable it and make sure we load the binary shader cache.

	With permission from Josh.A & Michael.T, deprecate Mac OpenGL support. For now this just means visibly warning users with message boxes - but in a future release OpenGL support will be removed from macOS.

	DR - vk - Compile fix

Change 3131564 on 2016/09/19 by Rolando.Caloca

	DR - vk - Submit Hint
	- Disable framebuffer recycling as its causing a hang

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.

Change 3131630 on 2016/09/19 by Mark.Satterthwaite

	More statistics in Metal added to track down where performance was going in a particular project but which may be more generally useful.

	#jira UE-35937

Change 3132696 on 2016/09/20 by Mark.Satterthwaite

	Use set*Bytes to handle uploading buffers < 4Kb when available - this is faster than lots of small Metal buffers and reduces the amount of GPU heap fragmentation. Where the API feature isn't available or hasn't been tested yet we'll use another ring-buffer inside the MetalCommandEncoder to emulate it.

Change 3132772 on 2016/09/20 by Mark.Satterthwaite

	Rework Metal's handling of RHISetStreamSource calls that override the stride of vertex declarations to be much more efficient.

	Duplicate CL #3137164:
	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.

Change 3140360 on 2016/09/26 by Daniel.Wright

	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.

	Duplicate CL #3140166
	Fix the video playback in Fortnite - bind our shader resource texture as the render-target texture as for some reason the playback code expects it there, even though we could never provide one.
	#jira FORT-30551

Change 3140584 on 2016/09/26 by Mark.Satterthwaite

	Duplicate CL #3140131:

	#jira FORT-30622

Change 3140586 on 2016/09/26 by Mark.Satterthwaite

	#jira FORT-30649

Change 3140594 on 2016/09/26 by Zabir.Hoque

	Fix benchmark shaders register bindings. TEXCOORD0 was bound to register 1 in VS and then register 0 in PS. DX12 treats this a PSO creation failuer unlike DX11 this was an error.

Change 3140601 on 2016/09/26 by Marcus.Wassmer

	New 'Cinematic' Scalability level.  Remove unused 'new' motionblur CVAR

Change 3140602 on 2016/09/26 by Zabir.Hoque

	CreateTexture3D on XB1 DX11 was leaking ESRAM by reserving it but not allocating to it.

Change 3141941 on 2016/09/27 by Olaf.Piesche

	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 3142035 on 2016/09/27 by Olaf.Piesche

	Fix compiler error from silly leftover bit of code.

Change 3142065 on 2016/09/27 by Benjamin.Hyder

	Updating Lighting Scenario map

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 3142537 on 2016/09/27 by Daniel.Wright

	Fixed r.ScreenPercentage with MSAA - a scissor rect was being setup during the resolve and not reset

Change 3142712 on 2016/09/27 by Daniel.Wright

	Separate category for ParticleCutout properties

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.

Change 3143464 on 2016/09/28 by Daniel.Wright

Change 3143661 on 2016/09/28 by Chris.Bunner

	Warning fix.

Change 3143723 on 2016/09/28 by Daniel.Wright

	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.

Change 3143860 on 2016/09/28 by Benjamin.Hyder

Change 3145064 on 2016/09/29 by Olaf.Piesche

	#jira UE-36091

	Pulling range update for vector distributions even when UDist is not dirty; some content has a lookup table and a clean dist, but the range values have not been baked; always pulling them should be safe and not significantly costly.

	SSearchBox will now only delay text changes while it has focus

	change summary:
	- added FObjectDuplicationHelperMethods::GatherDefaultSubobjectsForDuplication()
	- modified StaticDuplicateObjectEx() to map default subobjects created in the duplicated root object's ctor before entering the serialization pass. this preserves those instances instead of causing StaticConstructObject to destroy/recreate them during serialization as part of the UObject reference duplication logic.

Change 2984693 on 2016/05/20 by Phillip.Kavan

	[UE-30495] Fix BP editor crash on component rename following undo of component add action.

	change summary:
	- modified USimpleConstructionScript::CreateNode() to create the initial component template object in the transient package, so that subsequent undo actions restore to that state rather than to a valid BPGC-owned state.
	- modified StaticConstructObject_Internal() to restore the inclusion of RF_ArchetypeObject-flagged objects in the logic that sets new objects to 'PendingKill' state before recording them into the transaction buffer. this ensures that they can be GC'd when construction is undone in the editor. Tested against sample/repro steps in UE-21240 to ensure that it no longer crashes even with the original change from CL# 2832225 reverted (that fix has since been superceded).

	#jira UE-30495

Change 2984684 on 2016/05/20 by Phillip.Kavan

	[UE-30852] Fix BPGC custom property list delta generation & post-construct initialization/serialization to properly handle array values that differ from default in length but not inner element values.

	change summary:
	- modified UBlueprintGeneratedClass::BuildCustomPropertyListForPostConstruction()/BuildCustomArrayPropertyListForPostConstruction() to return a boolean value indicating whether or not a delta value was detected.
	- modified UBlueprintGeneratedClass::BuildCustomArrayPropertyListForPostConstruction() and FBlueprintEditorUtils::BuildComponentInstancingData() to ensure that array properties are emitted to delta property lists if the size differs from default, even if none of the elements actually differ from the default value
	- removed the ensure() for the array property case in FObjectInitializer::InitPropertiesFromCustomList(), as it is now a valid case to encounter an array property delta value without any actual delta element value overrides following it in the custom property stream
	- restored the bCanUsePostConstructLink optimization for non-native class types in FObjectInitializer::InitProperties()
	- modified UArrayProperty::SerializeItem() for the ArUseCustomPropertyList case to not empty the array when a resize is needed on load (read) - this fixes an edge case in the cooked BP component data stream when array size differed from default but only one or more of the inner values actually differed, in which case all the array slots were being reset (constructed/zeroed) but only the overridden value was being serialized (loaded) from the template data stream

Change 2981221 on 2016/05/17 by Dan.Oconnor

	Preventing spawning components with 'Within' markup specified, it is unsupported by the SCSEditor and Core UObject logic at this time. Likely logic is CoreUObject needs to avoid type checking for RF_ArchetypeObject instances and the SCSEditor needs to be more consistent about using that flag on its template objects

	#jira UE-28016

Change 2979304 on 2016/05/16 by Jamie.Dale

	Backing out some changes from CL# 2976673

	These caused an issue with Slate hit-testing. The more correct fix here is to make the Slate Windows OS layer treat window positions as relative to the top-left of the window client area, rather than relative to the top-left of the window itself (which includes the OS border). This now matches what other platforms do.

	To this end, FWindowsWindow::Initialize, FWindowsWindow::MoveWindowTo, and FWindowsWindow::ReshapeWindow all now consider the given window position to be relative to the window client area, and will consistently adjust it to relative to the window before moving/creating the OS window. This only impacts windows with OS borders (aka, non-fullscreen and non-Slate drawn windows).

	Prevents a re-entrancy crash caused by potentially complex thumbnail generators. In general, we should not be doing heavy lifting in the asset browser until the user has released their mouse. This is especially true when a user is clicking on the content browser tab to bring it to front for the first time. This is probably a good change regardless of the re-entrancy issue.
