e1db3cb334 Don't include commented out defines in the preprocessed code by default. 
- Defines will still be there if we're dumping the shader code for debug.
- This makes the code less unique in general case and also avoids unnecessary works that no one sees.

Change 3388455 on 2017/04/11 by Uriel.Doyon

	Changed Remove for RemoveSwap when clearing dynamic component references

Change 3388612 on 2017/04/11 by Simon.Tourangeau

	Support shaders in projects and in plugins
	When searching for a shader it will
	- First look in Engine/Shaders as usual
	- Then in project's Shader folder
	- Then in all enabled plugin Shader folders

	Project or plugin must be loaded in PostConfigInit phase
	Tested in PIE, engine (cooked, packaged)

Change 3388819 on 2017/04/11 by Arne.Schober

	DR - Faster MorpthTarget implementation. Changed the previous Gather aproach to a scatter based one. Reaching about 110GB/s on PS4 which is up to 4x faster than the previous implementation. On PC DX11 the impact is lower due to unecessary UAV barriers but still 2x faster on AMD and up to 6x faster on Nvidia Hardware.
	#RB Lina.Halper, Rolando.Caloca

Change 3388862 on 2017/04/11 by Guillaume.Abadie

	Allows Motion Blur and TAA in scene capture 2d.

Change 3388953 on 2017/04/11 by Uriel.Doyon

	Fixed issue where lights from hidden levels where affecting the lighting build, by checking if the light is registered before adding it.
	#UE-43220

Change 3389138 on 2017/04/11 by Arne.Schober

	DR - Fix crash when opening a Level without Contentbrowser open.
	#RB Matt.Kuhlenschmidt

Change 3389400 on 2017/04/11 by Uriel.Doyon

	- Renamed FMaterialResource::IsSeparateTranslucencyEnabled() to FMaterialResource::IsTranslucencyAfterDOFEnabled()
	- Removed different logic to determine if translucency after DOF was enabled, and centralized it into a single function: FSceneViewFamily::AllowTranslucencyAfterDOF()
	- FSceneRenderTargets::FinishRenderingSeparateTranslucency() now only resolves a single view, allowing better Begin/Finish scopes.
	- Renamed FSceneRenderTargets::SeparateTranslucencyDepthRT into FSceneRenderTargets::DownsampledTranslucencyDepthRT since this one is only allocated when rendering in downsampled mode.
	- Standard translucency is now rendered in the same resolution than translucency after DOF. (downsampled or full resolution)
	- Removed RenderTranslucencyParallel and merged it's logic into RenderTranslucency. Renamed DrawAllTranslucencyPasses to RenderViewTranslucency and added a parallel version RenderViewTranslucencyParallel.
	- Moved all debug draw logic (VisualizeLPV, ViewMeshElements and SimpleElementCollector) to a common place.
	- New option "r.AllowDownsampledStandardTranslucency" to control the downsampling of standard translucency. Affect blend module materials

	#jira UE-39505

	#CodeReview: matt.kuhlenschmidt
	#rb: n/a

Change 3397921 on 2017/04/18 by Joe.Graf

	Rewrote SlateFileDlgWindow's file filtering to allow for extensionless file selection and to remove the O(n^2) file filtering

	#CodeReview: arciel.rekman, matt.kuhlenschmidt
	#rb: n/a

Change 3398406 on 2017/04/18 by Rolando.Caloca

	DR - Fix shaders in plugins on Mac

Change 3399546 on 2017/04/19 by Benjamin.Hyder

	DR - Fix static analysis warning
	#RB none

Change 3403897 on 2017/04/21 by Arne.Schober

	DR - [UE-43898] - Someone missed a shaderversion bump which poisoned the DCC
	#RB None
	#jira UE-43898

Change 3404591 on 2017/04/21 by Olaf.Piesche

	#jira UE-41979
	Should never be crashing there, unless the mesh is changed after Init of the effect instance; this change safeguards against the number of mesh sections (and hence materials) changing after creation of the dynamic data to avoid the crash.

Change 3407451 on 2017/04/25 by Daniel.Wright

	Fixed Indirect Lighting Cache updates caused by capsule indirect shadows forcing point samples, breaking primitives using ILCQ_Volume

Change 3407452 on 2017/04/25 by Daniel.Wright

	Added r.AOJitterConeDirections, although disabled by default because it requires the temporal filter to be much stronger

Change 3408397 on 2017/04/25 by Daniel.Wright

	ViewFamily.bRealtimeUpdate is set to false if Slate is throttling (like when toggling show flags).  Volumetric fog discards the temporal history when not realtime, so you can see changes immediately.

Change 3408428 on 2017/04/25 by Daniel.Wright

	Changed 'r.AOMaxObjectsPerCullTile' default back to 512 as 256 causes artifacts with RTDF shadows

Change 3409764 on 2017/04/26 by Daniel.Wright

	Force dumping shader debug info for Global shaders when r.ShaderDevelopmentMode is enabled.  Most of the shaders you want to look at in a GPU capture are global shaders, and global shaders create few debug files.  'recompileshaders global' time 35s -> 38s for SM5.

Change 3411659 on 2017/04/27 by Daniel.Wright

	[Copy] Set Xbox One engine default screen percentage to 83.33 (1600x900), as ESRAM choices are dependent on this

Change 3411660 on 2017/04/27 by Daniel.Wright

	[Copy] Global distance field composite shader has a version for each flattened axis, which improves efficiency when updating a slab which is what camera movement typically causes

Change 3411667 on 2017/04/27 by Daniel.Wright

	[Copy] Discard distance field AO history buffer if it doesn't match the new buffer size.  This prevents reading uinitialized data after a scene render target resize.

Change 3411668 on 2017/04/27 by Daniel.Wright

	[Copy] Better indirect capsule shadow draw event info

Change 3411669 on 2017/04/27 by Daniel.Wright

	[Copy] Pass down FeatureLevel to AddSubjectPrimitive and GatherShadowsForPrimitiveInner instead of calling the scene's virtual function.  Showed up prominently in a sampling profile.

Change 3411755 on 2017/04/27 by Daniel.Wright

	[Copy] Occlusion queries are now always done before the base pass if a nearly full prepass is being used(DDM_AllOccluders or DDM_AllOpaque)
	* Removed r.OcclusionQueryLocation

Change 3411827 on 2017/04/27 by Daniel.Wright

	[Copy] Much cheaper implementation of IsForwardShadingEnabled which showed up prominently in sampling profiles - inlined function and no more unnecessary thread safety overhead

Change 3411829 on 2017/04/27 by Daniel.Wright

	Added an ensure to console manager when doing FindTConsoleVariableData* on a FAutoConsoleVariableRef

Change 3411837 on 2017/04/27 by Daniel.Wright

	[Copy] Worked around slow memcpy's being used to sort FSortedLightSceneInfo

Change 3411838 on 2017/04/27 by Daniel.Wright

	[Copy] Skip tracking MaterialRenderProxyMap on cooked platforms

Change 3411843 on 2017/04/27 by Daniel.Wright

	[Copy] Fixed r.ParallelShadows on PS4 and enabled by default engine-wide (saves 5ms RT with CSM)
	* Gnm was not tracking DepthClearValue when a depth target was set but not cleared
	* Gnm has a bug where TargetsNeedingEliminateFastClear does not persist across commandlist breaks.  Moved FinishRenderingGBuffer before RenderShadowDepthMaps to workaround (accidentally not in this changelist)
	* Shadow depth rendering was not using BindClearMRTValues to populate GNM parallel commandlist TargetsNeedingEliminateFastClear values

Change 3411873 on 2017/04/27 by Daniel.Wright

	[Copy] Deferred uniform expression caching.  Setting multiple parameters on a material only causes its uniform expressions to be recached once.
	* 280 calls to CacheUniformExpressions -> 120 during Fortnite combat (6.5ms -> 3.4ms)

Change 3411891 on 2017/04/27 by Daniel.Wright

	[Copy] GatherShadowPrimitives optimizations
	* Total GatherShadowPrimivies went from 2.3ms -> 1.3ms on PS4 with these changes in GPUPerfTest (duplicated 3x)
	* Much flatter primitive octree (16 -> 256 max primitives)
	* Primitives are culled against the shadow frustum before FPrimitiveSceneInfo or FPrimitiveSceneProxy are dereferenced in FilterPrimitiveForShadows
	* FilterPrimitiveForShadows work is done in a ParallelFor.  Primitive octree nodes are processed in different jobs.
	* StaticMeshWholeSceneShadowBatchVisibility now only stores entries for meshes with bRequiresPerElementVisibility (landscape).  Previously it was allocating and zeroing 500Kb 3x per frame (main view + 2 cascades) which cost ~.8ms on PS4.

Change 3412192 on 2017/04/27 by Michael.Trepka

	Fixed Clang compile errors in FortniteGame, partial copy of CL 3313426

Change 3412547 on 2017/04/27 by Daniel.Wright

	Fixed leak of FShadowMapAllocation and FLightMapAllocation's found by licensee

Change 3414239 on 2017/04/28 by Arne.Schober

	DR - UE-44500 - Removed use of Structured Buffer from MorphTargets due to HLSLCC not supporting it.

	#RB none
	#jira UE-44500

Change 3414754 on 2017/04/28 by Daniel.Wright

	Added VolumetricFogEmissive to ExponentialHeightFogComponent
	* Volumetric fog does not yet support precomputed lighting, so this is the only way to get an ambient lighting term

Change 3416859 on 2017/05/01 by Arne.Schober

	DR - Remove FeatureLevel from the Clear Functions to reduce area of error
	#RB Rolando.Caloca

	Removed early return landmine in USceneCaptureComponent2D::Serialize

Change 3431591 on 2017/05/09 by Daniel.Wright

	Disallow map building while in PIE, or PIE while buildling lighting

Change 3431594 on 2017/05/09 by Daniel.Wright

	Added RenderTargetFormat to UTextureRenderTarget2D, with choices of 8 bit, 16fp, 32fp and 1, 2 or 4 channels.

Change 3431667 on 2017/05/09 by Daniel.Wright

	Volumetric fog now supersamples lighting when the history is not available, reducing noise on areas that just came on-screen or after a camera cut.
	* The number of samples is controlled by r.VolumetricFog.HistoryMissSupersampleCount, defaults to 4, cinematic scalability uses 16
	* Under fast camera movement, volumetric fog cost went from 1.79ms -> 1.97ms with 4 samples, on a 970GTX

Change 3432366 on 2017/05/10 by Richard.Wallis

	Fix for MetalRHI Asserts When Using "Profile GPU" With RHI-Thread/Parallel-Execution.  Don't insert events when not in RHIThread or the actual single-threaded-render thread.

	#jira UE-36006

Change 3432367 on 2017/05/10 by Richard.Wallis

	Fix for Metal ReStartRenderPass assert with profiling.  macOS metal asserts when using "profileGPU" even with -norhithread argument set.

	Added no action to the allowed render pass restart store actions for the depth buffer avoiding the assert.  Interested to know the details if this is not a valid assumption to make - throwing away the depth buffer after a render pass I think would be a common case.

	#jira UE-44322

Change 3432409 on 2017/05/10 by Richard.Wallis

	Merged across CL 3415890 from Release-4.16 fix for (jira UE-43895)

	Fix for deferred store actions getting cleared when we don't have a valid render target.

Change 3432833 on 2017/05/10 by Daniel.Wright

	Fixed Ocean compile error

	Improved captions for Noise and VectorNoise material nodes

Change 3432947 on 2017/05/10 by Richard.Wallis

	Fix for shared Material Native Shader Libraries Don't Function With Iterative Cooking.   Keep latest versions of shader byte code in native shared material packaged build in an intermediate directory than can be reused on a later iterative cook.

	- Doesn't handle deletion of the intermediate directory contents.  Assumed to be a higher level requirement on non iterative cook flag.

	#jira UE-44657

Change 3433484 on 2017/05/10 by Arne.Schober

	DR - UE-44393 - Move ShaderPlatform into TShaderMap for extra debuginformation when it fails to find a proper shader. Also log when Gobalshaders are verified and recompiled.
	#jira UE-44393
	#RB Daniel.Wright

	Fixed static shadowing of volumetric fog and translucency causing shadowing past the lightmass importance volume.

Change 3433619 on 2017/05/10 by Daniel.Wright

	Skip recapturing reflection captures when PropagateLightingScenarioChange is being called for a level unload.  This leaves stale results in reflection captures around when hiding a level in the editor, but avoids the double recapture that happens when swapping lighting scenarios in game, and the unnecessary reflection capture update when exiting PIE.

Change 3433795 on 2017/05/10 by Arne.Schober

	DR - add cmdline to select a GPU vendor when multiple GPUs from differnt Vendors are installed into the same Machine
	#RB marcus.Wassmer

Change 3433941 on 2017/05/10 by Daniel.Wright

	Cone vs tile bounding sphere intersection tests for Light Grid culling of spotlights, which provides much tighter culling than just View space tile AABB vs light bounding sphere.
	* Forward shading BasePass 3.7ms -> 2.4ms in a scene with 24 spotlights on 970GTX
	* Volumetric fog 2.87ms -> 2.09ms in the same scene

Change 3436611 on 2017/05/12 by Simon.Tovey

	Improved name and tooltip for static mesh property controlling generation of alias tables for uniform sampling.

Change 3436676 on 2017/05/12 by Simon.Tovey

	Fix for fixed bounds being "invalid" unless set via the toolbar option.

Change 3436700 on 2017/05/12 by Simon.Tovey

	Crash fix.
	Issue found in https://udn.unrealengine.com/questions/355944/crash-in-fdynamicspriteemitterdatagetdynamicmeshel.html

	Particle proxies would have stale material resource pointers if the material is changed while the system was invisible.
	If the old material is freed during this time, the next time the system renders it will crash.

Change 3437367 on 2017/05/12 by Brian.Karis

==========================
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.
