Change 3761995 by Mark.Satterthwaite
Add the Metal compiler path to the local .pch filename to avoid problems when Xcode moves.
Change 3761996 by Mark.Satterthwaite
Emit more details when a pixel shader is found to have no outputs at all which Metal doesn't permit. More likely this is a bug in the shader compiler not configuring the in-out mask correctly...
#jira UE-52292
Change 3761999 by Mark.Satterthwaite
No need to avoid tessellation for FMetalRHICommandContext::RHIEndDrawIndexedPrimitiveUP anymore - that was from back when the tessellation logic was replicated in each RHI*Draw* implementation.
#jira UE-51937
Change 3762181 by Joe.Graf
Changed MaxShaderJobBatchSize to 25 on Mac as it reduced shader compile time by 21%

Change 3763111 by Richard.Wallis
Clone of CL 3763033 (Release-4.18):
Fix for crash upon launching packaged game on Mac with Share Material Shader Code enabled.
#jira UE-52121
Change 3763657 by Michael.Lentine
Invalidate ddc for skeletal mesh render data so that the duplicated vertex render structures are properly serialized.
Change 3763727 by Jian.Ru
Fix Player Collision view mode. It is caused by checking an uninitialized vertex buffer so the check always fail.
#jira UE-52052
Change 3763738 by Guillaume.Abadie
Implements SSR input post process material location.
Change 3764271 by Mark.Satterthwaite
Allow ControlPointPatch lists to flow through MetalRHI as it was setup to handle this transparently - the VSHS compute shader will convert them to triangles to draw. Report the same warning as in the pipeline creation stage as this hasn't been formally validated.
#jira UE-52454
Change 3764316 by Daniel.Wright
Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.
Change 3764318 by Daniel.Wright
Missing file
Change 3764321 by Daniel.Wright
Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.
Change 3764595 by Daniel.Wright
Added VolumetricLightmapDensityVolume asset icons
Change 3764701 by Michael.Lentine
Add duplicated vertices merging for meshmerge.

Change 3767209 by Chris.Bunner
PR #4203: Early-outs in UMaterialInstance parameter setters (Contributed by stefanzimecki)
#jira UE-52193
Change 3767772 by Mark.Satterthwaite
MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients. The Editor is already setup such that if the remote shader compiler is not configured & Xcode is not available locally the shader-compiler will be invoked to generate text shaders.
#jira UE-52554
Change 3768604 by Guillaume.Abadie
Polish up with new global shader function signature.
Change 3768993 by Guillaume.Abadie
Fixes r.Upscale.Panini cvars
Change 3769478 by Mark.Satterthwaite
Move the ue4_stdlib.metal & PCH into a temporary directory that exists for the lifetime of the SCW on the remote side as well as the local one and add this path as an include directory.
#jira UE-52587
Change 3769703 by Mark.Satterthwaite
For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.
Remove the depth-offset hack from the depth-only vertex shader again.
#jira UES-5651
Change 3769763 by Mark.Satterthwaite
Handle swizzle's in the hlslcc fma identification pass so that we reduce the number of instructions and the platform compiler can't break the instructions up.
Change 3769849 by Mark.Satterthwaite
Fix CIS error.
Change 3770517 by Richard.Wallis
Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.
#jira UE-51940
Change 3770688 by Uriel.Doyon
Fixed texture resolution returning 0 when running blueprint construction scripts at cook time.
Change 3771115 by Mark.Satterthwaite
Report errors from failed attempts to compile global shaders or we can't see why things fail on non-Windows platforms.
Change 3771263 by Mark.Satterthwaite
Change the way ManualVertexFetch is enabled on Metal platforms so that it is enabled when targeting Metal v1.2 and higher (macOS 10.12+/iOS 10+). This brings iOS in the Desktop Forward renderer back into line with the Mac.
#jira UERNDR-300
Change 3773472 by Guillaume.Abadie
Fixes a crash on PIE of SimpleComposure project.
Change 3773475 by Guillaume.Abadie
Fixes bug in editor viewport caused by SSR input changes.
Change 3774677 by Arne.Schober
DR - Deprecated SetLocal from the RHICmdlist
Fixed some unnecessary PSO collisions.
Change 3777037 by Mark.Satterthwaite
Remove incorrect change that caused a reference to "accurate::sincos" to appear in some Metal shaders rather than "precise::sincos".
Change 3777122 by Mark.Satterthwaite
Back out changelist 3777037 - I'm blind and wasn't seeing the real problem was a stale shader cache...
Change 3777196 by Mark.Satterthwaite
Fix text-shader compilation on iOS 10 - maybe iOS 9 too (untested!).
We need our own make_scalar type-trait template for ue4_stdlib.metal so that we still compile with older iOS runtime compilers and we can't use as_type to directly implement the packHalf2x16/unpackHalf2x16 intrinsics for these older runtime compilers either.
Change 3779098 by Rolando.Caloca
DR - vk - Fix query index
Change 3779275 by Mark.Satterthwaite
Silence the Metal runtime compiler warning caused by use of a deprecated enum value when running text shaders compiled for Metal v1.0/1.1 on a Metal v1.2+ OS.

Fixed invalid access in the resave package commantlet when building texture streaming material data for materials enabling tesselation.
Change 3784496 by Mark.Satterthwaite
Temporarily disable USE_OBJECT_COMPOSITING_TILE_CULLING for Metal shader compilation only - other platforms are unaffected - as it isn't working properly for some reason. need to work out what's up but don't want Distance Fields to be completely snookered in the interim.
#jira UE-52952
Change 3784608 by Rolando.Caloca
DR - Copy 3784588
- Fix for drivers returning out of date swapchains during resizes
Change 3784734 by Mark.Satterthwaite
Real fix for UE-52952 - MetalShaderFormat wasn't propagating the full thread-group value.
#jira UE-52952
Change 3784741 by Mark.Satterthwaite
More Metal debugging commandline options "-metalfastmath" & "-metalnofastmath" to force fast-math on or off for all shaders, must be using runtime-compiled shaders (i.e. -metalshaderdebug or r.Shaders.Optimise=0) to take effect.
Change 3787103 by Guillaume.Abadie
Kills BuiltinSamplers UB
Change 3787207 by Guillaume.Abadie
Sorry, compile fix that were fine with local changes...
Change 3787396 by Marcus.Wassmer
PR #4271: UE-52901: Set VIS_Max meta to hidden (Contributed by projectgheist)
Change 3788028 by Peter.Sumanaseni
Working linear HDR exr output from sequencer
Change 3788536 by Mark.Satterthwaite
Track whether the Metal shader uses the discard_fragment function as when this is used but without any other outputs we know we need to bind at least one render-target or a depth-stencil surface but we don't know which. This lets us correctly error when we encounter a shader with no outputs at all which Metal doesn't permit.
#jira UE-52292
Change 3788538 by Mark.Satterthwaite
Let's try mitigating UE-46604 on Nvidia by retaining resource references in the command-buffer. This shouldn't be necessary and isn't typically on other vendors but we haven't been able to reproduce this reliably enough to get to the bottom of it.
#jira UE-46604
Change 3789083 by Guillaume.Abadie
Implements global shader permutations. Example in ScreenSpaceReflections.cpp.
Change 3789090 by Guillaume.Abadie

#jira UE-53061
Change 3791593 by Guillaume.Abadie
Reinvalidates shaders with shader permutations.
Change 3791884 by Daniel.Wright
Added BP setter for LowerHemisphereColor
Change 3791886 by Daniel.Wright
Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks
Change 3792256 by Guillaume.Abadie
Fixes a bug where permutation was not actually serialised in FShader, so was ending up recompiling shader at every load.
Change 3792884 by Marcus.Wassmer
Copying //UE4/Partner-AMD to Dev-Rendering (//UE4/Dev-Rendering)
Change 3793200 by Marcus.Wassmer
Copying //UE4/Partner-IDV-SpeedTree to Dev-Rendering (//UE4/Dev-Rendering)
Speedtree 8 support
Change 3793206 by Brian.Karis
Added color grading control BlueCorrection to correct for artifacts with "electric" blues due to the ACEScg color space. Bright blue desaturates instead of going to violet.
Added color grading control ExpandGamut which expands bright saturated colors outside the sRGB gamut to fake wide gamut rendering.
ACES changes.
Change 3793344 by Marcus.Wassmer
Fix editortest compile
Change 3794285 by Guillaume.Abadie
Serializes PermutationId according to archive rendering version to avoid issues with old material that were serializing a shader map into UObject.
Change 3794307 by Guillaume.Abadie
Resaves uassets that were modified between 3789648 and 3794285
Change 3794627 by Mark.Satterthwaite
Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.
Change 3794631 by Mark.Satterthwaite
Missed updating mtlpp's build.cs for TVOS.
Change 3794651 by Uriel.Doyon
UPointLightComponent::GetUnitsConversionFactor() now takes the cone angle as parameter. This allows to fix spotlight unit conversion when using lumens.

Lightmass now uses the highest density VolumetricLightmapDensityVolume settings that affect any part of a cell
Change 3797221 by Daniel.Wright
Reduced default SphericalHarmonicSmoothing based on RoboRecall tests. Now only active with strong direct lighting from static lights by default.

Merged CL 3731188 and CL 3733311 from //UE4/Dev-Editor.
----
Improve responsiveness of Open Asset dialog.
On large projects, there's a noticeable delay when opening and searching/filtering assets.
Stopwatch measurements on my machine (seconds for ~122,000 assets):
before with this CL
ctrl-P 1.4 0.45
search 1.8 0.55
CollectionManagerModule was the main culprit for search/filter slowness.
Open Asset delay was due to filtering out plugin content. We were doing a lot of redundant work for what is essentially a read-only operation.

Reduced impact of dynamic vertex buffer RHI stall in D3D12
- In most cases we can avoid the stall if the vertex buffer has never been used before.
- Only when a buffer has an existing SRV do we need to stall.
- Also, delete copy and move constructors of FD3D12ResourceLocation. Moving or copying an instance of this class leads to double free crashes, so this is now a compile error rather than a runtime crash.
This saves an average of 2ms frame time in a StW lastperftest replay, with r.screenpercentage 10.

Change 3772867 by Thomas.Sarkanen
Nativization now correctly generates and builds code for "Client" builds
Overall this is a bunch of hacks, but necessary for nativization to work at present. Once the cooker and UAT both have a concept of "Client" targets, this can be implemented properly.
Instead of building to a "Client" directory, we build to "Game" for client-only platforms (like PS4, XboxOne)
Also we need to add "Client" targets to the whitelist for the nativized assets plugin, as UBT still thinks it is building for "Client"

Improvements to the Cpp backend to allow VC++ to compile nativized code more effectively
Added a new scoped helper to wrap areas of the code in PRAGMA_DISABLE_OPTIMIZATION. This helps with functions that are large tables or long lists of initializations.
Split anim node initialization up into functions, called from a seperate function dedicated to initializing anim nodes. This splits the 5k+ line constructor into mutiple smaller functions, which the compiler has no problems with.
Overall (along with splitting up the anim BP into functions in the asset) this reduces compilation time for the worst-case compilation unit from ~11m 40s to ~2m 32s.

Fixes to enable auto-nativization for animation blueprints
For blend profiles in particular, I've added subobject support to the fake import table building for nativized assets:
- In FEmitterLocalContext::FindGloballyMappedObject, if we dont find the referenced asset then we traverse the object's outer chain if it is a subobject. We add it to UsedObjectInCurrentClass if we find its outer.
- Updated the structure used to build the fake import table to include a specified outer. Beforehand we assumed that all objects referenced by the import table were 'top-level'.
- Updated the fake import table building code in FLinkerLoad::CreateDynamicTypeLoader() to use the new specified outer if found. This asserts if it couldnt find the outer in the already-parsed dependencies (as it reverse-iterates). If in the general case thius turns out to be a problem we can move this to a two-pass system.
Disabled fast-path optimization when running a native anim BP, as native code is faster!

Updated FMallocLeakDetectionProxy to not use a critical section internally on top of thread safety measures performed by FMallocLeakDetection and the underlying FMalloc implementation. The improvements are biggest on Mac, in particular in low framerate situations, as Metal RHI uses malloc heavily on multiple threads, but it's also a nice 10% improvement on a high end PC.

Editor: Rewrote CallInEditor support and promoted it so it can be used on functions in any class, not just blueprints derived from AActor:
- CallInEditor used on native UFUNCTION() declarations will now show up without having to make a BP subclass
- CallInEditor can now be used as a top-level keyword in the UFUNCTION() declaration (e.g., UFUNCTION(Category=CoolCommands, CallInEditor))
- Now shows each function as a separate button, placed in the category associated with the function
- The button strip entry is now searchable by function name or tooltip
- Prevented operating on functions that have parameters or return values, which would crash before
- Removed the duplicate copies of properties placed in the Blutility section
- Added a scoped transaction around CallInEditor execution
- Allowed functions to be marked as CallInEditor in addition to custom events (currently we don't allow editing category or tooltip on custom events...)
Editor: Moved Experimental/EarlyAccessPreview details customizations up to UObject so it can be used on any class, not just actors/components

Speculative fix#2 for a server crash/assert. If the timing is right, it's possible for the server to try to re-load a placed-in-map actor that was previously garbage collected.

Also added/improved some logging that will help in case this doesn't fix the issue.

Change 3665063 by Daniel.Broder
Fixed crash in GameplayTagQueryCustomization when choosing "Save and Close" on GameplayTagQuery after setting a query due to nullptr NotifyHook in CloseWidgetWindow.
Added additional if (StructPropertyHandle.IsValid()) wrappers and one check(StructPropertyHandle.IsValid()); the former to be consistent with other code and prevent possible crashes, the latter to at least catch the cause of a possible crash properly without having to change the code more significantly to handle it gracefully.
Also changed some if( X ) to if (X) to match coding standards and provide consistency within the file.
Michael, I'm Reviewing you on this fix since you brought this change over from Framework. And Marc because you reviewed him on that change.

Copy CLs 3383318 & 3388506 from //Orion/Main/Engine/Source/Runtime/Engine/...
- Been testing with this for a while now
- This change makes particle effects show up on the current frame's pose for skel meshes as well
Removed my StopAllMontagesByGroupName temp hack
CL 3383318
Delay dispatching of AnimEvents (Notifies and Montage Events) until after we receive an updated animation pose (if applicable).
This fixes AnimNotifies playing particle effects using a socket location using last frame's pose. Now they use the current frame's pose.
CL 3388506
Delay clearing of MontageInstances and triggering 'OnAllMontageInstancesEnded' until all Montage Events have been dispatched.
Also fix SkelMeshComponent ticking on dedicated servers when rejoining in progress.

Change 3778200 by Nick.Darnell
UMG - Making it possible to cancel delays and all animations on widgets. Useful when destroying a widget and needing to stop any async state.
Change 3777612 by Zak.Middleton
Perf: Added option to CharacterMovementComponent to skip immediate forward prediction for proxies on the frame they receive a network update (bNetworkSkipProxyPredictionOnNetUpdate). This avoids all forward prediction sweeps and floor checks on those updates. Intermediate frames will interpolate with prediction. This can also be disabled globally with the CVar "p.NetEnableSkipProxyPredictionOnNetUpdate 0".
Added NetworkSmoothingDisableProxyPredictionForPawnLOD to force disabling full simulation for LOD >= this value (currently 3, so bottom 75 pawns). This takes precedence over current distance and view angle checks for prediction (mesh interpolation is untouched).
Change 3774338 by Ben.Woodhouse

#jira UE-52287 Prevent cook metadata like DevelopmentAssetRegistry.bin from being packed into a shipping game, by moving it into a Metadata subdirectory and updating deployment scripts to avoid that directory.

Texture streaming optimization where a maximum texture resolution for each level streaming data is computed per view.
This is used to cull irrelevant levels and reduce the async task number of iterations.

Fix for Mac editor session no longer accurately tracking Mouse location after moving between Desktops in Mission Control on 10.12.6. Problem stems from the extra call to update the slate cached window position in mouse move while dragging, which is itself is a hack but apparently this is needed as we don't get window position updates on Mac while dragging (although I couldn't see any -ve side effects without it) then the OS (in 10.12.6) doesn't always push out a final window did move notificaiton when changing desktops which leaves the window according to slate incorrectly positoned to it's frame.
Solution is to either remove the mouse-move-while-drag window position hack or add a final window position update to the mouse-up event while dragging - this change is the latter.
#jira UE-37553
Change 3697501 by Richard.Wallis
Move audio processing over to audio bus tap. Currently on Mac Media audio playback uses OS media player mixer rather than Engine as existing implemtation, using AVAssetReader, now suffers from poor performance with new Media Framework. This audio tap version replaces that asset reader implementation but also suffers from bad quality audio hence is still disabled at the top of AvfMediaTracks.cpp.
Original Code Review Description:
Convert Mac to Play audio through the engine MediaFramework API rather than using AVMediaPlayer. This is the Mac implementation only - this should work ok on iOS but unable to test due to missing audio type implementation (throws error "Init Buffer on unsupported sound type name = Synth type = 5"), as such is only enabled for Mac. There maybe some extra tweaks required for iOS on app backgrounding etc if this feature is enabled.
- Stuttering Audio Performace issue investiagation: Re-Tested this implementation against [now fixed] current Mac implementation which was working fine last year and that implementation now has the same audio output quality (performance) issues as this one. Basic investigation seems to point to somewhere in the engine audio handing. When poor audio is heard the FMediaAudioResampler::Generate() function is dequeing an IMediaAudioSample sample buffer and the audio sample queue usually has 50-100 of these IMediaAudioSample buffers waiting in the queue. I think the AvfMedia playback system is providing the sample buffers in good time but they are not getting consumed "fast" enough. This under consuming also occurs if I force the Core Audio - Audio Unit mixer to use 48000 samples/sec.

Skip compiling opacity and opacity mask inputs on opaque surface materials. Previously the code was always added to the shader, sometimes we force opaque materials down a masked path which then calls the dormant code unintentionally. A safer fix for UE-48254.
Partially reverted previous fix in CL 3608303 which removed a material instance optimization caching the overridden base properties.

UE4 - UE4 - Changes from intel. Increase number of worker threads on Windows to if hyperthreads (hyperthreads √ 2) else cores √ 1 up to a max of 22 workers. Increase MAX_THREADS multiplier per bank from 22 to 26. Intel VTune ITT event annotations. Wrapped in same function as your existing CPU events and enabled with √vtune. Optimize NV cloth by consuming FVector instead of FVector4 out of the solver. Vertex buffers were using FVector all along. ~15% improvement. Optimize cloth copy to vertex buffer by adding prefetch (similar to how bones are already done). Move local to world cloth transform from CPU to GPU. When simulating lots of vertices game thread was becoming bottleneck doing matrix multiply. Add your TaskGraph task switch latency test code.

Change 3710454 by Mark.Satterthwaite
Refactor the way we compile Buffer<> & RWBuffer<> types for Metal so that we can support the type-conversion semantics of HLSL/D3D.
- Buffer<> types are converted to Linear Textures unless the internal type is 3-compnent or the STRONG_TYPE macro is added as a type-qualifier. Linear Textures require an MTLTexture "view" object be created around the MTLBuffer which is the backing-store and it is typically best if that buffer is marked as Private (GPU-only) memory, reading from this in the shader then uses the texture-fetch hardware to perform the format conversion on load.
- RWBuffer<> & 3-compnent Buffer<> types are converted to use template functions to load/store - the implementation of which will read the format from the BufferSizes meta-table and determine which type-conversion to apply. Function-constants are used to specialise the shader where feasible to reduce branch costs (function-constants are a Metal feature that allow efficient runtime recompilation of bytecode shaders).
- Buffer<> & RWBuffer<> types where the STRONG_TYPE macro is added as a type-qualifier (only does something on Metal, everywhere else it is #define'd away) are compiled as "raw" Metal buffers of the inner-type (e.g. float4 for Buffer<float4>) and the MetalRHI runtime will enforce that only SRVs/UAVs of the proper format are bound to it. This is necessary in a couple of cases (BoneMatrices, NumCulledLightsGrid, CulledLightDataGrid & ForwardLocalLightBuffer buffers) which are used in a larger number of shaders as Linear Textures have poorer performance than Buffer<>/RWBuffer<>.
- Most of the complications to generating subtly different Metal code for different OS/device combinations have been factored out into ue4_stdlib.metal which acts as an extension to the Metal shader standard-library and helps simplify the MetalBackend code - particularly helpful for Buffer<>/RWBuffer<> but also texturecube_array and the SM6 wave-related intrinsics.
- Reverted some of the awkward Metal-specific changes Richard.Wallis & Arne had to make to the high-level shaders as they aren't necessary anymore.
- Made the existing Metal-specific changes to use uint32 for all light-grid injection buffers apply to all Metal platforms again (I had hoped that it would not be necessary anymore, but it is much faster this way).
- STRONG_TYPE is actually hlslcc's "invariant" keyword applied as a type-qualifier to a Buffer<>/RWBuffer<> type - only valid when using Metal which exports this through ILanguageSpec and #define'd out for everyone else.
- Old versions of iOS (anything earlier than iOS 10.3) won't be able to use this new code, so every buffer will be treated as "raw" and the MetalRHI will now properly report when something goes awry rather than it leading to mysterious rendering errors and crashes.

Use GPU morph targets on Mac - the necessary buffer conversions will always be available there. For iOS it can only be supported if iOS 10 is the minimum OS & Metal standard so leave that on the CPU path for now.
Change 3713494 by Richard.Wallis
Fix for hitch when PIE unloading sublevel. PerformReachabilityAnalysisOnObjects is spawing multiple threads in Editor builds as there is an extra code path that results in Critical Section locking within a singleton type static object - this is a bottle neck for multiple threads. However they all just need to read the data not change it. Replaced FScopeLock with a Read/Write version allowing these threads to all take a read lock at the same time to reduce contention.
Changed the FUObjectAnnotationDense implementation only - left the sparse implementation alone as its not currently affecting this - although we could proactivly change that too.
Also tested again repro in linked bug UE-24711.

Implement ByteAddressBuffer/RWByteAddressBuffer in hlslcc in a similar manner to StructuredBuffer/RWStructuredBuffer so that the backends don't need too much modification. Implement the necessary changes into MetalBackend to make this work for Metal.
Load/Store{+2,3,4} & Atomics are supported. Counter operations are not supported and aren't likely to be.
Change 3713636 by Mark.Satterthwaite
Enable LPVs for Mac Metal.
- Rework some multi-dimensional arrays & array-index dependent HLSL code that hlslcc simply can't cope with, the mesa-glsl compiler core is only capable of dealing with 1 dimensional arrays and array-indexing can't itself be directly dependent on the result of an array-index operation.
- MetalRHI needs to ignore any SetRenderTargets call that binds nothing at all as you must bind at least one target (UAV, RT, Depth/Stencil) for it to be able to do anything sensible.
- Turn on LPVs for Metal as it works now.

Lightmass correctness fixes
* After these changes, point, spot, directional and sky lights closely match reference renderer Mitsuba after light unit conversions
* Photon density trimming intended for direct photons was affecting indirect photons as well. This caused high noise for point / spot lights with a large attenuation radius. Indirect photon density even for small lights is 5x with this change, which improves 2nd bounce quality.
* Removed legacy fudge factor on point / spot light photon energy
* Spotlights no longer emit based on indirect photon paths. Fixes excessive photon energy from spot lights as they were emitting outside of the cone.
* Fixed photons computing one more bounce than requested.
* Added an option to use the Radiosity solver for all multibounce, replacing photons. Useful as a reference but generally too much noise indoors.
* Fixed visualization of photons without final gather

No more Metal Shader Model 4 - instead we have to have a Metal Shader Model 5 w/o Tessellation as Nvidia's shader compiler is broken on all tessellation shaders in 10.13.0 and above. There is no guarantee that they will fix this prior to 10.14 and I can't afford to disable tessellation entirely as if I do that then the AMD & Intel compilers will also regress. As there is no Shader Model 4 platform on Mac anymore I've amended the LevelEditorActions to disable the preview modes when no appropriate shader platform is available.

Disable the METAL_SM5_NOTESS shader platform again - I can workaround the Nvidia pipeline state compiler crash by changing the buffer address space from "constant" to "device" as we're managing to confuse the poor thing. This won't materially affect AMD or Intel as they don't care much about this, but to limit performance issues on Nvidia we only need to do this for Tessellation Compute shaders.

Render thread dynamic resolution & TAA upsample.
Merging //Tasks/UE4/Dev-DynamicRes/...@3694528 to //UE4/Dev-Rendering/...
New features breakdown:
- TAA upsample compute shader that accepts screen percentage from 50% to 200%, with a faster shader permutation for consoles;
- Material no longer have to deal with BufferUV, and post process material after TAA upsample can sample any scene buffer seamlessly;
- Material texture per view mip bias to produce sharper images with TAA upsample;
- Render thread dynamic resolution heuristic is fully plugable by game code (for VR plugin specific heuristics);
- Dynamic resolution in PIE and game builds;
- Busy time queries in the RHI to be implemented on the different platforms so that the dynamic resolution heuristic can exactly associate GPU frame times with screen percentages in its history;
- Game user settings to enable/disable dynamic resolution;
- In editor viewport screen percentage config to previsualise and test content at different screen percentage.
Fixes:
- Various fixes for algorithms producing different outputs at different screen percentage.
- Various fixes for algorithms sampling outside view rects.
Refactors:
- TAA shader
- Moved some screen percentage specific members from FSceneView to FViewInfo for thread race bullet proofing.
Aknowledgements:
- VR plugins are broken
- DFAO still have some artifacts

[FORTNITE] [CONSOLE] [+] Improved frame syncing mechanism
- Improves input latency by allowing the game thread to sync to the swap chain flip of the previous frame.
- Added "r.GTSyncType" CVar to control how the game thread syncs with the rest of the pipe.
- r.GTSyncType 2 will sync the game thread with the flip of the swap chain, preventing the pipe from getting too long and causing excess input latency.
Platforms are required to implement RHIWaitForFlip and RHISignalFlipEvent, and call RHIInitializeFlipTracking on RHI startup.
A separate thread monitors the progress of frame flips and signals task graph events as they pass their corresponding frame index.
In r.GTSyncType 2 mode, the game thread is signaled by this flip tracking thread.
[~] Unified platform specific sync interval CVars (D3D12.SyncInterval, D3D11.SyncInterval, r.PS4FlipRate, RHI.SyncIntervalOgl) into one: rhi.SyncInterval
- 1 == 60Hz
- 2 == 30Hz
- 3 == 20Hz
[-] Removed large number in XboxOneTime. Adding this arbitrary number prevents us from comparing timestamps from FPlatformTime::Seconds() and various OS callbacks (e.g. flip timings).

#UE4 - proper handling of "pending connection lost"
- triggered only if a connection is lost and there no "owning actor" to deal with the connection loss
-- added Rejoin and CleanedUp states to connection to make sure that the pending connection lost delegate only fires at the appropriate time
- delegate returns the unique id of the player if known (still possible to be unknown if connection lost after NMT_Hello)
- changed debug output on timeout if the net connection was already in the process of being destroyed
-- occurs when game hitches during the pending destroy 2 second wait
-- ReceivedAcks should have been called to clean things up quietly in those 2 seconds but blocking the game thread will cause the cleanup to look like a timeout
- added userid to UNetConnection::Describe
- bad split screen player handling of unique id
-- splitscreen uniqueid was overwriting the primary player id
-- only store the id on the child connection
- added some clarifying comments

LLM Update - Memory reductions, Summary page, enum scopes, refactor and cleanup of tags
* Remove all static arrays and hard limits from LLM. Everything is now dynamically allocated using the internal LLM allocators. The overhead when LLM is disabled is now only 48K (was 40MB)
* re-wrote LLMMap. Now stores an int32 index rather then pointer in the HashMap array. Also, changed the Values to be arrays for structs instead of structs of arrays. Means that the tag can be stored in a single byte. Changed the size of the allocation size from int64 to int32. All this takes the memory down from around 600MB to 100MB. It was 120 bytes per allocation, now 29 bytes.
* changed all LLM scopes over to enums. This has a number of benefits; LLM can be enable in Test, less CPU overhead, stored in a byte (LLM overhead /= 8)
* summary page for content creators where all lower-level stats are grouped under one Engine stat
* renamed ELLMScopeTag enum to ELLMTag
* renamed LLM_SCOPED_TAG_WITH_ENUM macro to LLM_SCOPE
* removed Tracker arg from LLM_SCOPE and added LLM_PLATFORM_SCOPE macro
* fixed GenericPlatformMallocCrash stat. Although it seems not be be used anymore
* fixed BackupOOMMemoryPool stat (now shows in both default and platform pages)
* added separate LLM enums for XB1, PS4 and D3D12 (PS4LLM.cpp/h etc.)
* lots of changes adding/removing/renaming tags
* added LLMArray and FLLMObjectAllocator classes
* disabled asset tag tracking by default because it takes up so much memory even when not used
* enable LLM in all non-shipping builds. In Test the on screendisplay won't show because it uses the stats system but it till still write out the csv.
* all the stat macros have been left as they were and can be enabled on the LLM_STAT_TAGS_ENABLED define. These are needed for the asset tagging.
* disabled LLM_TRACK_PEAK_MEMORY because there is a problem with the way it adds the peaks for multiple threads. This needs to be fixed.
* added a CVar to control the csv write interval: LLM.LLMWriteInterval
* added static arrays for the enum tags setup. Easier to manage and removes need for slow switch statements.
* renamed FLLMThreadStateManager to FLLMTracker to make it consistent with the enum
* fixed program size stat which was broken recently on PS4. This was due to initialisation order and global platform stats setup

Initial support for hotfixing live assets from .ini files
- This allows clients and server to patch certain assets in memory whenever .ini file hotfixes are downloaded
- Only CurveTables and DataTables are supported for now
- The new asset content must be in Json format, the same format the editor uses for importing
- Assets that are hotfixed will be synchronously loaded if they're not already in memory. They'll be retained in memory afterwards.
- IMPORTANT: Json data must be supplied on a single line, and all double quotes must be escaped!
- The changes must go in the Game.ini file and use the following syntax:
[AssetHotfix]
+CurveTable=("/Game/Folder/MyCurveTable","[{\"Name\":\"Default\"}]")
+DataTable=("/Game/Folder2/MyDataTable","[{\"Name\":\"Foo\"}]")

Loading time improvements
- This shaves off up to 10 seconds of load time on PS4 in Athena
Details:
- Fixed multiple sub-levels not being able to be enqueued for loading in a single client frame. Athena has ~300 sub-levels, so this ended up wasting up many seconds.
- Fixed 3D world being rendered while loading (frees up game thread cycles for throttled streaming)
- UWorld::AllowLevelLoadRequests() was not allowing load requests to go through while an async load was in progress and the match had started. It now allows this as long as the world isn't being rendered (loading screen.)
- Eliminated extra 2 second delay before loading screen is dismissed (in Athena only)
- Note: A side effect of this change is that the progress bar may not update as smoothly on loading screen. We'll look at tuning the throttle settings if it ends up being a problem.

[FORTNITE] [PS4] [!] Fix memory stats in the old PS4 memory system
- Physical memory stat now includes garlic and onion allocations. CPU OOMs will result in "AvailablePhysical" being close to 0.

All Fort analytics events now contain a GameState attribute indicating the active GameState ClassName when the event is sent.
Added some new context to crashreporter to help identify Athena matches near and long term.
* Near Term: GameNameSuffix - set via FCoreDelegates::CrashOverrideParamsChanged
* Added bools to the params to indicate WHICH ones are changing
* Allows you to set only some values, and clear them out.
* Hooked up in FortGameState::PostInitializeComponents.
* FortGameState clears it (for returning to main menu).
* FortGameStateAthena sets it (for going into an Athena match).
* Only does this when it's a true GameMode GameState instance (ie, not PIE) so PIE crashes aren't modified.
* Long Term: GameStateName - set via FCoreDelegates::GameStateClassChanged.
* This works for ANY crash on ANY game.
* Hooked up in GameState::HandleMatchIsWaitingToStart.

[FORTNITE] [PS4] [~] Modified the way memory is allocated on Playstation to make more memory available to the CPU.
- Previously the amount of texture memory wasnâ•žt fixed due to the way the defrag memory is allocated on PS4. This meant we had to have a significant amount of slack.
- With the new configuration, we have a guaranteed texture memory pool, so the slack can be significantly smaller, meaning we can give more memory to the CPU, which is where most of our memory pressure is.

Enable GC clustering for actors and blueprints in Fortnite
- This shaves off about 10 ms on GC frames in Athena on PS4 (~52 ms -> 42 ms)
- Clustering doesn't work on building actors because they're very dynamic, but general Fort static meshes and blueprints are clustered!
- This gets us into the realm of shippability on console for very large UObject counts

Force largest distance field atlas size in Athena
- We now force the largest distance field atlas size before preloading Athena content (512x512x1024 = 256 MB). This helps with load times because it's expensive to re-create this texture on consoles, and typically it gets resized over a dozen times.
- Added new CVar "r.DistanceFields.ForceMaxAtlasSize" (defaults to zero)
- Important: Currently we never "reset" this atlas texture. This will be a problem when going back to play Campaigns after preloading to play Athena. I will look into this soon!

GameFeedback, and the widget switcer utilize this to avoid unnesacary activations of a screen that is immediately being deactivated.
Root issue of the mentioned bug is that activation of the quest screen created a latent navigation du to the deferal of scrolling into view.
This is still an issue in general, there isn't much we can do about it. Other than avoid activating a panel that will deactivated that frame as we did with the code changes in this CL.

Lightmass skylight solver improvements
* Lightmass uses a filtered cubemap to represent the skylight instead of a 3rd order Spherical Harmonic. Directionality in shadowed areas is improved. Mip level is chosen based on the ray differential for anti-aliasing.
* Multiple skylight and emissive bounces are now supported with a radiosity solver, controlled by NumSkyLightingBounces in Lightmass WorldSettings. More bounces results in longer build times, and the radiosity time is not distributable.
* The mapping surface cache is now rasterized with supersampling, reduces incorrect darkness in corners
* Combined direct lighting, photon irradiance, skylight radiosity and diffuse in the mapping surface cache so final gather rays only have to do one memory fetch, speeds up lighting builds by 7%.
* Added support for Embree packet tracing although no solver algorithms use it yet
Change 3618413 by Daniel.Wright
Swarm hands out the most expensive tasks in roughly a round robin ordering among distribution agents. Lightmass processing of a single task is multithreaded, so ideally the most expensive tasks are evenly distributed among active agents. This has the biggest impact in small scenes with 10's of high resolution lightmaps, and with a distribution farm. Build time in one scene went from to 113s -> 47s.

GitHub #2655: Optimization for shadow map resolution selection for spot lights
* Use the radius of the inscribed sphere at the cone end as the spot light's screen radius

Fix for ScissorRect settings in d3d11 being lost under certain scenarios

* However FD3D11StateCacheBase::ClearState() clears all the states, which removes scissor rectangles and causes problems for certain routines (FScene::UpdateSkyCaptureContents)
* Now SetScissorRectIfRequiredWhenSettingViewport will always set a effectively disabled ScissorRect on each FD3D11DynamicRHI::RHISetViewport call, just like d3d12 does

Volumetric Lightmaps - higher quality precomputed GI on dynamic objects and GI on Volumetric Fog
* Enabled by default on all maps, effective after a lighting build. This replaces the existing Precomputed Light Volume and Indirect Lighting Cache features.
* New Lightmass World Settings: VolumeLightingMethod, VolumetricLightmapDetailCellSize and VolumetricLightmapMaximumBrickMemoryMb.
* Lightmass computes lighting samples in an adaptive grid, with higher density around geometry inside the importance volume. Positions outside the importance volume get lit with the border texels.
* Improved Lightmass volume solver to use importance photons and full adaptive final gather, so volume samples have similar quality to 2d lightmaps.
* A static indirection texture is built covering the importance volume and flattening the brick tree by storing the offset to the highest density brick at each indirection cell.
* Seamless and efficient GPU interpolation across density levels is achieved by adding a single row of padding to bricks, copied from neighbors, and stitching up bricks with lower density neighbors
* The Volumetric lightmap stores Irradiance as a 3 band SH, which is 27 floats, quantized into 28 bytes, 7 texture lookups.
* A full screen barebones material using Volumetric Lightmaps costs .42ms on 970 GTX, while Indirect Lighting Cache Point costs .32ms
* Sky bent normal is also stored for stationary skylights and Directional Light Shadowing for Single Sample Shadow receiving.
* Volumetric fog, Movable components, unbuilt Static Components, SingleSampleShadow receiving and Capsule Shadows use Volumetric Lightmaps if available
* New Visualization show flag for Volumetric Lightmap sample points
* Level streaming of volume light data is not currently supported with this method
Change 3525461 by Daniel.Wright
Lowered default r.Shadow.RadiusThreshold for Epic shadow settings as it was causing a lot of visible artifacts from small objects popping out. This will increase shadowmap cost slightly (13.5ms RT -> 14.3ms RT in Fortnite on PS4, no measurable GPU difference).

Submitted on Richard Wallis's behalf as he's on holiday:
Mac fixes for Compute Skin Cache rendering issues (resulting in incorrect positions and tangents) and for recomputing tangents. Problem sampling from buffers/textures as floats with packed data. Some of the data appears as denorms so get flushed to zero then reinterpreted as uints via asuint or in Metal as_type<uint>(). Fix here for Metal seems to be to use uint types for the skin cache SRV's and as_type<> to floats instead.
There could be some other areas where we're unpacking via floats that could affect Metal and I'm not sure how this will impact on other platforms.

Correctly implement ClipDistance for Metal as an array of floats as required by the spec. and fix a few irritating issues from the merge that should not have.
- When compiling a tessellation vertex shader in the SCW direct mode we can't evaluate non-existant defines and we don't actually need to.
- The define names, values & shader file name are irrelevant to the Metal output key, but the shader format name & Metal standard really do matter - should speed up Metal shader compilation a bit.
- Move the shader vertex layer clip-distance to index 2 to avoid conflicts.
- Don't default initialise the debug code string for Metal shaders or it won't print out the actual code....

Simple threaded CSV Profiler
To capture:
- On the commandline, add -csvCaptureFrames=N to capture N frames from startup
- On the console, use csvprofile start, csvprofile stop or csvprofile frames=N to capture a fixed number of frames
- Instrument with CSV_SCOPED_STAT(statname), CSV_CUSTOM_STAT(statname,value).
CSV capture is enabled in all builds except shipping
- Please do not check in the instrumentation √ we don╞t want to pollute the engine with lots of additional instrumentation. We may add some minimal level of instrumentation at some point

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.

* 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

Duplicated from Fortnite CL 3243458:
D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory.
On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage.
Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX

memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time.

Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future.

DR - PSO stats
Change 3255958 on 2017/01/12 by Mark.Satterthwaite
Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed.

DFAO optimizations
* Changed the culling algorithm to produce a list of intersecting screen tiles for each object, instead of the other way around. Each tile / object intersection gets its own cone tracing thread group so wavefronts are much smaller and scheduled better. 3.63ms -> 3.48ms (.15ms)
* Replace slow instructions in inner loop with fast approximations (exp2 -> sqr + 1, rcpFast, lengthFast) 3.25ms -> 3.09ms (.16ms)
* Moved transform from world to local space out of the inner loop (sample position constructed from local space position + direction) 3.09ms -> 3.04ms

- Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case.
CL 3231395:
Update D3D12 RHI:
- Fix deferred MSAA path in RHI
- Add Pix3.h support
- Cleanup SetName usage and remove it from shipping builds.
- Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value.
- Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64
- Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version.
- Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident.

Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written.

ESRAM support stage 1:

Support for the old allocator is still available (for now) via the define NEW_ESRAM_ALLOCATOR

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.

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.

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.

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 3055904 on 2016/07/19 by Daniel.Wright
Reflection environment normalization improvements
* Indirect specular from reflection captures is now mixed with indirect diffuse from lightmaps based on roughness, such that a mirror surface will have no mixing. Reflection captures now match other reflection methods like SSR and planar reflections much more closely.
* When a stationary skylight is present, Reflection captures are now normalized as if the initial skylight will always be present, giving consistent results with static skylight reflections. The skylight and reflection captures with sky removed used to be normalized separately, compacting the relative brightness between the sky and scene.
* Added r.ReflectionEnvironmentLightmapMixing for debugging lightmap mixing issues. This toggle was previously not possible due to prenormalizing the capture data.
* The standard deferred reflection path (r.DoTiledReflections 0) can no longer match the results of the compute path or base pass reflections, as it would require MRT to accumulate the average brightness
* Removed unused r.DiffuseFromCaptures
* Cost of reflection environment on PS4 increased from 1.52ms -> 1.75ms with this change, but decreased back to 1.58ms by reducing tile size to 8x8
Change 3055905 on 2016/07/19 by Daniel.Wright

Change 3062244 on 2016/07/22 by Daniel.Wright
Discard old prenormalized reflection environment data on load
Change 3062283 on 2016/07/22 by Daniel.Wright
MSAA support for the forward renderer
* AntiAliasing method is chosen in Rendering project settings, DefaultSettings category
* Deferred passes like shadow projection, fogging and decals are only computed per-pixel and can introduce aliasing
* Added Rendering project setting VertexFoggingForOpaque, which makes height fog cheaper and work properly with MSAA
* The AntiAliasing method in PostProcessSettings has been removed, this may affect existing content
* Added r.MSAACount which defaults to 4
* Integrated wide custom resolve filter from Oculus renderer, controlled by r.WideCustomResolve
* GBuffer targets are no longer allocated when using the forward renderer
* Decal blend modes that write to the GBuffer fall back to SceneColor emissive only
Change 3062666 on 2016/07/23 by Uriel.Doyon
Added legend to streaming accuracy viewmodes
Added a new helper class FRenderTargetTemp to be reused in different canvas rendering.
Exposed the pass through pixel shader so that it can be reused.

Planar reflections
* New actor and component
* The scene is rendered to texture with a mirrored camera and a clip plane each frame
* The reflection texture is then applied to opaque pixels in a deferred pass, with distance and angle from plane fades
* Translucent materials apply the nearest reflection plane in the base pass
* Planar reflections require the project setting 'Support global clip plane for Planar Reflections' to be enabled, since writing to SV_ClipDistance all the time adds about 15% BasePass GPU time on PS4
* Fixed global distance field in materials which had been broken since moving global distance field properties into the view uniform buffer
* Fixed PS4 removing system-value semantics when output from vertex shader and not read in next stage

#UE4 Getting crash reporting working again on linux servers. Since -Unattended is now being passed BEFORE the target folder, the cmd line parsing code was failing so now it parses tokens and switches in a more general way. Also, diagnostics.txt had the incorrect case, since the d is supposed to be capitolized and the crash report processor is case sensitive.

#UE4 Move ValidateEnumProperties into ValidateGeneratedClass, it was happening too early in the generation process so was being called at an invalid time.
As a result of this ValidateEnumProperties will not be called correctly for compile on load blueprints, that issue is covered in UE-24569

#HTTP #HttpRetry
- Add new Failed_ConnectionError code to EHttpRequestStatus to distinguish between connection errors and protocol errors.
- Changed HTTP retry logic a little bit
* If a response was received, retry on service-specific explicit HTTP codes (defaults to empty)
* If a response was not received and we did not send a full request, automatically retry
* If a response was not received and a request may have been sent, retry if the verb is GET or HEAD (should be idempotent)
- Adjusted Curl/IOS/Mac/PS4/WinInet to try and distinguish Failed_ConnectionError where possible
* Other systems will default to Failed which is ok (ConnectionError is an opportunistic categorization)
* Opened a PS4 ticket to try to improve detection, but unfortunately there's no way (currently) to distinguish between send timeout, connection timeout, and receive timeout, the latter being the problematic case.
- Removed the concept of global/default HTTP retry status codes. No system has enough knowledge to set those globally.
* Individual requests still specify explicit "retryable" codes and McpServiceBase sets that on each request on a per-service basis

[AUTOMERGE]
Fixed EQS BP query wrappers getting GCed before wrapped query finishes #UE4
Fixes FORT-18649 - Patrols don't spawn consistently
- The patrol blueprint was waiting (endlessly) for an EQS query to finish but because the wrapper could be GC-ed while the EQS query was running the delegate would never fire

Change 2797758 on 2015/12/10 by Mark.Satterthwaite
Defer calls to AUGraphUpdate into FCoreAudioDevice::UpdateHardware - this call will synchronise the calling thread with the CoreAudio thread/run-loop so that the CoreAudio graph is safe to modify and this may incur a significant stall. This means it is far more efficient to amortise the cost of all changes to the graph with a single call. To ensure correctness the audio format conversion components are cached and disposed of after the call to AUGraphUpdate so that any existing operations on the CoreAudio thread are completed prior to disposal.
