============================
  MAJOR FEATURES & CHANGES
============================

Change 3780878 by Nick.Darnell

	UMG - Providing more information when the compile fails to find a bindable widget.


Change 3780855 by Gil.Gribb

	UE4 - Fixed a linear search in EDL that caused performance problems for very large maps. Saves half the load time in FN-BR.


Change 3780803 by Thomas.Sarkanen

	Dont create animation tasks for skeletal meshes that have no anim instance

	This avoids some wasted work for non-animated attachments, such as pickaxes

	#jira FORT-61523 - Don't create anim worker tasks if no AnimBP


Change 3780741 by Yenal.Kal

	#jira FORT-60177

	Fixed the bug where the anim branching points (begin and end) may be triggered twice incorrectly.

Change 3780663 by Gil.Gribb

	UE4 - Batching for audio thread commands.


Change 3780466 by Ben.Marsh

	Add error matcher for generic Microsoft errors (eg. 'cl : Command line error D8049 : command line too long to fit in debug record')

Change 3779937 by Nick.Darnell

	UMG - Adding an accessor on UUserWidget to get the owning player state easier, since it's a common operation.


Change 3779858 by Sam.Zamani

	#http
	use separate "-multihomehttp" instead of "-multihome" for routing http socket

	#jira FORT-61666
	#tests none

Change 3779288 by Michael.Trepka

	Changed FMacConsoleOutputDevice::Serialize to use FString's GetNSString() instead of converting the string using FPlatformString::TCHARToCFString to make it safer in case of garbage text passed in Data

	#jira FORT-59762

Change 3779062 by Mike.Fricker

	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.


Change 3778954 by Nick.Darnell

	Slate - Making the Horizontal and Vertical analog keys configurable in the navigation config.  Tweaking how fast the navigation is with the analog stick, trying to tune the feeling.


Change 3778896 by Ben.Marsh

	Separate FNameEntrySerialized from FNameEntry, rather than deriving from it. It has to be allocated differently, and many fields cannot be shared between the two.

	#jira

Change 3778807 by Ben.Marsh

	Fix Tencent include paths not registering if workspace directory contains a space.

	Tencent include paths currently have a trailing backslash, and this is surrounded by quotes if the root directory contains a space. The backslash is interpreted as escaping the trailing double quote.

	#jira

Change 3778686 by Luke.Thatcher

	 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.

	#jira FORT-61390

Change 3778679 by Thomas.Sarkanen

	Fix Linux server crash - dont attempt to run threaded work in a single-threaded environment

	We dont attempt to run animation update work multi-threaded in the same conditions that we didnt attempt to run animation eval work previously.

	#jira FORT-61548

Change 3778591 by Ben.Woodhouse

	Add build config to FPSChart HTML output

	#jira FORT-56478

Change 3778175 by ben.marsh

	Remove code to trigger an ensure on Arxan guards. We already send analytics for this, and don't need this legacy path. There is a large number of incoming ensures with this callstack that are clogging up crash reporter.

	Will remove all the surrounding code in a later update to a development branch.

	#jira

Change 3777750 by Chris.Gagnon

	- Slate now supports a CustomBoundary Navigation type wich allows a custom handler if the boundary is hit.
	  - This provides the ability to have normal navigation while within the boundary and the custom function only on the boundary.
	  - This differs from Custom which is a full override of the navigation behavior.

	 [XBOXONE] [~] Remove stall in D3D12 CreateRHIBuffer
	 - Buffer update is enqueued as a task on the RHI thread instead of stalling the RHI thread for the duration of the update.


Change 3775488 by Thomas.Sarkanen

	Prevented skeletal meshes that are not being ticked due to URO from dispatching tick tasks

	#jira FORT-61157 - Run anim update on worker, even if not visible

Change 3775219 by Bob.Tellez

	#UE4 Dont SerializeThumbnails when calling savepackage while editoronly data is excluded (cooking). This saves a lot of memory while cooking

Change 3774621 by Bob.Tellez

	#UE4 Move Tree rebuilding during cook from Serialize to PreSave to avoid building the tree multiple times for a single platform. Also properly clear out CacheMeshExtendedBounds.

	UE4 - Fixed rare crash caused by unmounting pak files.


Change 3773920 by Gil.Gribb

	UE4 - Added experimental option r.StartPrepassParallelTranslatesImmediately which allows the parallel translate tasks from the prepass to start before we init shadows. Disabled by default.


Change 3773896 by Thomas.Sarkanen

	Push non-rendered anim updates back onto the worker thread

	Now when meshes are set to EMeshComponentUpdateFlag::AlwaysTickPose, we optionally kick of a task to perform parallel update only (no evaluation).

	#jira FORT-61157 - Run anim update on worker, even if not visible


Change 3773886 by Gil.Gribb

	UE4 - Reduced r.RHICmdMinCmdlistForParallelSubmit from 2 to 1.

Change 3773458 by Gil.Gribb

	UE4 - Added an experimental option to do the slate render before waiting for the rendering tasks.


Change 3773011 by Robert.Manuszewski

	Header (uasset) and export (uexp) files will now be compared seperately when running cook commandlet with -diffonly to avoid situations where a mismatch in size of the header produces more differences between exports.

	+ Renamed ini setting to ignore header differences from SkipHeaderDiff to IgnoreHeaderDiff


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"

	#jira FORT-52823 - Nativizing Player Animation Blueprints

Change 3772408 by Robert.Manuszewski

	Cook commandlet will now report full property name when running a diff against the existing cook (-diffonly)


Change 3772359 by Thomas.Sarkanen

	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.

	#jira FORT-52823 - Nativizing Player Animation Blueprints

Change 3771975 by Zak.Middleton

	Fix character proxies doing up to two floor check when only rotation changes. Add some optional verbose logging to FindFloor() and ComputeFloorDist().

	#jira FORT-61134

Change 3771421 by Ori.Cohen

	Fix CIS


Change 3771052 by Robert.Manuszewski

	Package diff improvements (-diffonly mode for cooker). Exposed max diffs to report to ini and added the ability to suppress header differences reporting as they are usually a result of differences in exports anyway.


Change 3771039 by Bob.Tellez

	#UE4 Allowing use of -FPS in PGO profile builds


Change 3770747 by Ori.Cohen

	Added missing stat named events for anim bp


Change 3769616 by Arciel.Rekman

	UBT: Use response files for compiler when compiling for Linux.

	- Some command lines are too long when cross-compiling on Windows, which is a problem for non-unity builds (or local changes that result in exclusion of checked out files from the lumped units).

Change 3769457 by Gil.Gribb

	UE4 - Added eviction to r.DoLazyStaticMeshUpdate. It just removes 10 prims a frame in a rolling fashion.


Change 3769136 by Michael.Noland

	Engine: Improve IsServerDelegateForOSS to allow it to use the play world during PIE even if no context was passed in


Change 3768736 by Robert.Manuszewski

Change 3768506 by Thomas.Sarkanen

	Duplicating CL 3764661 from Paragon:

	Only update Children attached to Sockets in USkeletalMeshComponent::PostBlendPhysics().
	Saves ~20% of STAT_UpdateChildTransforms and ~10% of STAT_UpdateLocalToWorldAndOverlaps in 5ofEach_Dusk_vs_Dusk automation test.

	#jira OR-46341

	#tests LaneMinionFXTests, monolith w/ full teams.

Change 3768504 by Thomas.Sarkanen

	Duplicating CL 3758315  from Paragon:

	Optimized PostAnimEvaluation when URO is skipping a frame with no interpolation. Skip unnecessary work.
	PreEvaluateAnimation() is now only called if we're about to evaluate anims. PostEvaluateAnimation() is also called only if we have evaluated animations.
	Therefore PostEvaluateAnimation() has been pulled inside of PostAnimEvaluation() instead of FinalizeTransforms.
	Added a call to ConditionallyDispatchQueuedAnimEvents() in the event that we're not calling PostBlendPhysics because we have not evaluated or interpolated anims.
	Added missing call to PostEvaluateAnimation() for PostProcessAnimInstance.

	#jira OR-46341

	#tests minion FX perf map, lane minion test map, monolith match with 2 full teams.

	Better pack UTexture* classes

Change 3766272 by Thomas.Sarkanen

	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!

	#jira FORT-52823 - Nativizing Player Animation Blueprints
	#jira FORT-57378 - Perf optimization: animation blueprint improvements

	#jira FORT-58878

Change 3753986 by Ben.Zeigler

	#jira UE-45505 Fix issue where FCoreUObjectDelegates::OnAssetLoaded was being called from an inner loop inside EndLoad. Maps would register components from that callback, and if those registers started their own loads, those objects would be returned in a partially loaded state.

Change 3753175 by Thomas.Sarkanen

	Fix hang in animation editor menus

	Sound waves were being loaded by the visibility delegate for the 'play' button overlay. This caused major hangs as the ogg compressed data was built on the fly. Handled the unloaded asset case in the various delegates.
	Also made the menu larger, as picking a sound wave was all but impossible when you couldnt even see one in the list.

Change 3752185 by Ben.Marsh

	Reduce cook time regression caused by correcting package names to match case on disk (to fix deterministic cooking problems). Switched to use IPlatformFile::GetFilenameOnDisk(), and improved performance of FWindowsPlatformFile::GetFilenameOnDisk() by using GetFinalPathNameByHandle() instead of recursively searching up the directory tree.

	#jira

Change 3751813 by Ben.Marsh

	Improve parsing of diagnostics for deterministic cooking test. Now allows multiple lines in the generic EC error/warning matcher if indented more than the first line, and skips over empty lines.

	#jira

Change 3750413 by Ben.Zeigler

	Fixes for cook save performance regressions. Add GetAllMarks to object and use that to dramatically reduce contention for the object mark annotation. Implement ShouldLoadForServer/Client directly on some core classes to stop it from calling the slow generic one
	Fix issue where refreshing tags for asset registry would do a very slow array delete/add
	Improve speed of redirectcollector, there's no need to force-rehash the soft object path list as the remove handles it conditionally

Change 3748530 by Mike.Fricker

	Fixed non-determinism of landscape grass across platforms/compilers

	This causes bushes to be located in different places depending on what platform you were playing on.

	1)  Random number reseeds were happening as part of function arguments to FVector(), but function argument evaluation order is unspecified, and behaved differently on Consoles/Mac/Windows.  Fixed this bug.

	2)  Strings used for foliage CRCs could use different character sizes on different platforms.  Now we always use ANSI.

	3)  Strings used for CRCs could have possibly have different case.  Now forced lowercase.

	#jira FORT-60109

	Avoid string alloc on every ServerMove() call on the server.


Change 3747560 by Gil.Gribb

	UE4 - Fixed XBox and Windows thread priorities. Only 2 though -2 seem usable and some of the old values were being ignored.


Change 3747548 by Gil.Gribb

	UE4 - Changed thread pool to be TPri_SlightlyBelowNormal so that they will not preempt HP task graph tasks.


Change 3747544 by Bart.Hawthorne

	When detecting if Oodle is installed, use the newest version instad of the oldest one.


Change 3746440 by Robert.Manuszewski

	Dterministic cook issues reporting improvements

	- Huge performance improvements
	- Added new metric to the summary: NumberOfDifferencesInPackages
	- Diff stats have their own section now (Package.Diff)
	- When running with -diffonly there commandlet will not log the Warning/Error summary anymore
	- Callstacks are no longer logged with instruction addresses
	- Because callstacks are no longer logged with addresses I can collapse them for structures that otherwise would be split into multiple separate callstacks
	- Callstacks, Serialized Object and Serialized Property are now indented
	- Each asset is capped at 5 entries. If there's more differences, they'll be logged as single warning.
	- Replaced \r\n with \n in the callstack log to make it work better with EC

	#jira FORT-59919


Change 3746426 by Gil.Gribb

	UE4 - Tuned dispatch in the deferred renderer. Added r.DoPrepareDistanceFieldSceneAfterRHIFlush and defaulted it to on.


Change 3746348 by Mike.Fricker

	Added new CVars to toggle level streaming behavior
	- No effective change to engine yet.  The defaults values enable the same default behavior.
	- New CVar:  "s.ForceGCAfterLevelStreamedOut"   (Whether to force a GC after levels are streamed out to instantly reclaim the memory at the expensive of a hitch.)
	- New CVar:  "s.ContinuouslyIncrementalGCWhileLevelsPendingPurge"  (Whether to repeatedly kick off incremental GC when there are levels still waiting to be purged.)
	- New CVar:  "s.AllowLevelRequestsWhileAsyncLoadingInMatch"  (Enables level streaming requests while async loading (of anything) while the match is already in progress and no loading screen is up)


Change 3746127 by Gil.Gribb

	UE4 - Slight tweak to more agressively batch occlusion queries.


Change 3746111 by Cecil.McRae


Change 3745681 by Bob.Tellez

Change 3745631 by Matt.Kuhlenschmidt

	Fix details panel crash after compiling blueprints that have edit conditon properties


Change 3744544 by Gil.Gribb

	UE4 - Downgraded a fatal error to a warning. Example: Found package without a linker, could find SceneComp in /Game/AIDirector/AIDirector_Fortnite, but somehow wasn't finished loading. This is a sort of cook mismatched caused by the fact that all PS4 cooks have server-only data in them.

	#jira FORT-59879


Change 3744419 by Matt.Kuhlenschmidt

	Fix opening color picker causing values to change.  Was due to conversion between srgb and linear color.

Change 3743376 by Gil.Gribb

	UE4 - Added r.WarningOnRedundantTransformUpdate to produce warnings on redundant transform updates.


Change 3743372 by Gil.Gribb

	UE4 - Added a stat for distance field verification...which takes a very long time, but does not affect test or shipping config.


Change 3743030 by Bob.Tellez

	#UE4 Revert some code the was accidentally merged to UE4Main

	#jira UE-52032

Change 3742611 by Josh.Markiewicz

	#UE4 - fix for crash in destructor probably related to the freeing of memory via default destructors AFTER CefShutdown() has been called

	#tests crashes before, no crash after (not sure if it was a 100% crash but this seems better regardless)

Change 3742187 by Nick.Darnell

	Slate - Adding a new optional parameter to direct routing for the widgets under the cursor in Slate Application.  Essentially ProcessReply occasionally needs to know the widgets under the cursor, the previous implementation, just used the routing path, this results in missing sending mouse leave messages to widgets under the cursor when dragging begins, which often left things with hover effects in bad states.


Change 3742053 by Michael.Trepka

	Copy of CL 3713881

	Added -buildscw to Mac Build.sh script to build ShaderCompileWorker in addition to the requested target. Xcode passes it to the script when building non-program targets.

Change 3741442 by Ryan.Gerleve

	Fix initialization order warnings


Change 3741370 by Ryan.Gerleve

	Back out changelist 3689397. The memcpy in one of the FInBunch constructors is not portable and causes this change to break networking on Android.

	#UE4 Gave OodleHandlerComponent a short name so it doesnt hit maxpath length issues on build machines.


Change 3740209 by Nick.Darnell

	UMG - Finishing the ability to add a "Custom" method for Navigation.  Currently the editor implementation leaves me wanting, but it works for now.  You can put the name of a function to call (needs to match a signature that returns a UWidget).


Change 3740207 by Nick.Darnell

	Slate - Navigation attempts when the user claims they are doing custom or explicit, if those methods don't return a valid widget, we don't treat it like the attempt failed and fallback to default navigation methods.  Instead we use it as a trigger to indicate that no navigation should occur and treat it like a stop.


Change 3740189 by Bob.Tellez

	#jira FORT-58911

Change 3736109 by Michael.Trepka

	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.

	#jira FORT-55309

	- refactor the GPU profiler so it's no longer dependent on the stats system and can work in Test builds
	- add support for pre-declared CSV stats, using FNames (these are required for GPU stats)
	- add DECLARE_GPU_STAT macro which handles STATS and CsvProfiler declarations

	Note: still a few issues to resolve with GPU stats: these randomly go to 0 at times during a replay on XB1, the GPU total is lower than the stat unit number, and the unaccounted stat is too large due to missing stats


Change 3712297 by Mike.Fricker

	Fixed huge client hitch when applying changes to in-game options
	- Every component was being re-registered when r.SimpleForwardShading was updated by the scalability system, even if the value hadn't changed.  Now, it only re-registers components if the value changes on the fly.  (e.g. when turning Shadows off or on 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...)

Change 3691805 by Bob.Tellez

	#UE4 CIS fix


Change 3691784 by Bob.Tellez

	#UE4 Optimization for exiting PIE. Texture streaming managers have an optimization for game worlds but were not using them for PIE worlds


Change 3691273 by Aaron.McLeran

	#jira UE-50650 Fix memory/event leak in USoundWave::AudioDecompressor

	Fix is to only delete the decompress/pre-cache task in game thread during FinishDestroy and not allow sounds to start playing unless the precache task has finished.

Change 3691268 by Aaron.McLeran

	#jira FORT-56228 LogAudio:Warning: spam causes severe performance drop on the Mac Platform

	Reducing log level

Change 3690547 by Ryan.Gerleve

	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. This was happening because CanClientLoadObject was always returning true for these (null) objects, even if the NetGUID corresponded to a map actor that shouldn't be loaded. Also added/improved some logging that will help in case this doesn't fix the issue.

	#jira FORT-55763


Change 3690451 by Lukasz.Furman

	changed branch name testing in engine hacks to use case insensitive match

Change 3690270 by David.Ratti

	Cache weak object ptr in FNetworkObjectInfo to avoid reconstructing one every time we need to lookup its actor channel.

	#jira FORT-57156

Change 3690227 by David.Ratti

	Added optional TWeakObjectPtr parameter to packagemap functions GetOrAssignNetGUID, SUpportsObject. This allows you to pass in a weak ptr for an object if its already created. If you pass in null, the functions will create them internally.

	This fixes some common cases where we were converting the same object into weak ptr multiple times in a frame.

	#jira FORT-57156

Change 3690184 by David.Ratti

	Cache net connection weakobjectptr when building consider list instead of constructing it again for every actor.

Change 3689397 by Bart.Hawthorne

	Changed FOutBunch and FInBunch uint8 entries to use bitfields instead of bytes which knocked 86% off of our net tick time

Change 3689056 by Lukasz.Furman

	3rd attempt for branch name checking in engine code hacks

Change 3689050 by David.Ratti

	First pass at removing use of TWeakObjectPtr from core replication classes. This should reduce FWeakObjectPtr::Get usage.

	Still expecting to see FWeakObjectPtr::operator= come up a lot. Going to tackle this in a second pass which will require some deeper refactors.

	#jira FORT-57156

Change 3688972 by Bob.Tellez

	#UE4 Add build target flag to control DISABLE_GENERATED_INI_WHEN_COOKED


Change 3688864 by Ryan.Gerleve

	Fix broken logic to find the "best" replay sample for character movement when we don't find two samples to interpolate between. Now uses the sample closest to the current time. Also added some debug drawing.

	#jira FORT-56553

Change 3687654 by Bob.Tellez

	#UE4 IsLoadedByEditorPropertiesOnly is not working properly so I removed it from FullLoadAndSave


Change 3681342 by Bob.Tellez

	#UE4 Added a FullLoadAndSave option to cooking, which simply loads all content then saves it to avoid the overhead of managing which packages need to be cooked. Large perf improvement for those who cook by the book and can fit the entire game in memory


Change 3681014 by Yenal.Kal

	#jira FORT-56209
	#jira FORT-56272

	Fixed a bug in the ability system where the ability ended callbacks could cause the ability end to be called again in the same call stack even though the ability is activated only once.

	This was happening because we were broadcasting the event before we decrement the active count.

Change 3680739 by Michael.Trepka

	Warn about NaN float literal values when translating HLSL to Metal instead of failing, plus added more detailed warning/error messages for NaN and unhandled values

	Added some debugging code to help track down why shaders are hashing poorly.


Change 3671498 by Luke.Thatcher

	 [~] Modify new frame syncing to reduce performance regression seen when the game is running over budget.
	 - Rather than forcing a flip sync after we kick off one frame early, we just continue to kick frames if we time out. This allows the game thread to get ahead when we're over budget.
	 - The game thread will naturally resync with the vsync when we return to being in budget.

	#jira FORT-55842

Change 3671079 by Ryan.Gerleve

	Fix an edge case where the PackageMap on the server would try to resolve objects from default NetGUIDs even if their outer has already been garbage collected. This could lead to a completely unrelated object being returned instead of null, leading to asserts and potentially other issues.

	#jira FORT-55763


Change 3670487 by Zak.Middleton

	Optimize some low level details of UNetConnection::ClientHasInitializedLevelFor() and UNetDriver::IsLevelInitializedForActor(). Add cached WorldPackage for NetDriver to avoid repeated GetOuterMost() and Casts. Remove rendundant virtual GetWorld() calls, and mark UNetDriver's version "final" to let it optimize away virtual call. Made UNetConnection::ClientVisibleLevelNames a TSet instead of TArray, since it is searched frequently when there are streaming levels present.

	#jira FORT-55999

Change 3670351 by Zak.Middleton

	Fixed server crashing after hotfixes have re-imported curve table data
	- The hotfix system is capable of replacing the content of a UCurveTable on the fly
	- If any systems had references to inner curves on that curve table, they would become invalid
	- This needs to be fixed in 1.6.4 (tonight) and also in 1.7

	#jira FORT-55792

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.

	#jira FORT-55102 - Server Crash UAnimInstance::StopAllMontagesByGroupName

Change 3780616 by Gil.Gribb

	Fixed and reenabled r.DelaySceneRenderCompletion

Change 3778979 by Gil.Gribb

	UE4 - Improved the performance of grass updates and added the ability to not do all of them every frame.

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

	Convert the D3D12 PSO caches to use RwScopeLocks. This change is courtesy of a shelf from Gil, plus a couple of minor fixes.
	Saves up to a millsecond of frame time in CPU-bound scenarios

Change 3773462 by Gil.Gribb

	UE4 - Add particle batching. This is disabled by default but can improve thread scheduling when there are lots of very fast particle systems.

Change 3771375 by Hongyi.Yu

	Fixed the crash where ability components are unregistered and then re-registered, which usually happens in PIE.

Change 3771368 by Ben.Zeigler

	#jira UE-52670 Add project setting bValidateUnloadedSoftActorReferences that is true by default to match current behavior. If you set it to false it will no longer load packages to look for soft actor references when deleting/renaming actors.

Change 3771173 by Seth.Weedin

	Auto manage attachment support for AudioComponent- An opt-in feature that allows AudioComponents to cache their AttachParent/AttachSocket and only attach themselves when playing audio, detaching after playback is completed. Set to false by default.

Change 3766554 by Gil.Gribb

	UE4 - Added a new option to add and remove from static draw lists on demand. This is off by default.

Change 3766427 by Nick.Darnell

	Slate - Finally adding Opacity to SWidget.  Any widget can now be alpha animated at will, no more need to waste overhead by wrapping things with SBorder or making them userwidgets just to be able to animate a fade.

Change 3761682 by nick.darnell

	Athena - Introducing a way to interrupt the request to scroll and item into view.  In cases where you're animating, quickly showing and hiding, with the item widgets unavailable for a few frames, you enter cases where the deferred navigation is resolved after you've canceled showing a dialog stealing focus.

Change 3761416 by Ben.Zeigler

	#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.
	Right now it doesn't package them at all, we could change it to package them as Debug Non-UFS if desired
	Change it so the asset audit UI will only load DevelopmentAssetRegistry.bin files, the cooked registry files don't have enough information any more to be useful
	Remove ability for runtime game to load DevelopmentAssetRegistry.bin, this ended up not being useful

Change 3730756 by Ben.Woodhouse

	HISM optimization:
	Gil's change to skip trees with only one level of hierarchy (working around badly tuned content issues)
	Change vert threshold to 2K.
	1-2ms renderthread win without impacting GPU when rendering point lights

Change 3724029 by Zak.Middleton

	Increase allowed time for movement substep duration. Don't want to lower between 2 iterations, as this is not used much in practice other than deflection and movement mode changes, and that will change behavior (lose momentum). This new setting will absorb longer hitches in the common case (moving without collision or falling).

Change 3723985 by Marc.Audy

	SignificanceManager PostSignificanceUpdate functions can now be executed sequentially on the game thread as well as concurrently in the parallel for (old behavior)

Change 3722910 by Jian.Ru

	Amortize shadow cache update caused by resolution change
	Changed to use view distance vs. view space z when calculating whole scene shadow resolution which is less sensitive to camera rotation

Change 3718247 by Yenal.Kal

	Fixed the bug where the gameplay effect durations can show incorrect values after rejoin or after server time drifting away from the client.

Change 3716343 by Jamie.Dale

	Adding Korean and Turkish to the localization automation


Change 3710534 by Uriel.Doyon

	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.
	The culled size is defined by the new r.Streaming.MinLevelTextureScreenSize.

	This requires to remove primitives with big UV density from the level data.
	Those primitives get moved to the dynamic lists.
	This is controlled by r.Streaming.MaxTextureUVDensity

Change 3707207 by David.Ratti

	Remove look ahead-vectors prediction in FNetViewer. This (requires) a line trace which is not desirable or really accurate anymore. This saves us a line trace per connection per multicast rpc.

	unify reliable multicast rpc handling: these now do relevancy checks and are not sent to non relevant clients

Change 3706272 by Thomas.Sarkanen

	Added utility/math functions to aid in optimizing anim blueprints

	Added VectorLengthXY to get the 2D length of a 3D vector. Avoids unecessary conversions.
	Added polar->cartesian->polar conversion helper functions for expensive frequently-used anim graph functionality.

Change 3706159 by David.Ratti

	PlayerState/ASC replication optimizations from Polge: this puts the net update frequnecy on player state back to 1hz while forcing netupdates on the player state actor when the ability system component needs to update

Change 3692891 by David.Ratti

	Optimizations for UNetConnection::ClientHasInitializedLevelFor: build acceleration map of actor outer's (ULevels) -> Visibility bool. Existing logic stays the same.

Change 3691392 by Aaron.McLeran

	#jira UE-50628 Fix audio trying to sync load bulk data with EDL enabled

	- Fix log error in BulkData.cpp
	- Make the first stream chunk be force inline payload in bulk data flags so it loads immediately vs in async IO system
	- Make audio stream chunks get as close to 256 k chunks as it can, zero-pad rest to be 256 k aligned
	- Fix up DDC key, serialize AudioDataSize separately from chunk DataSize

Change 3682683 by Zak.Middleton

	Add bOnlyTickMontageOnDedicatedServer variable to AnimInstance, to avoid anim bp updates on dedicated server. Turn on to fix hitching from queued ServerMove() calls, and some free perf during all montages on the server.

Change 3678771 by Ori.Cohen

	Added the ability to turn on stack walk during hitching vs lightweight stats

Change 3676363 by Ori.Cohen

	Added the ability to get callstacks as part of hitch detection

Change 3674877 by Keith.Judge

	Move definition of GFailedToFindParamCollectionBufferQueue to ShaderBaseClasses.cpp so that all targets can successfully compile.

Change 3672515 by Bob.Tellez

	Added code to play wind particle effects

Change 3670909 by Zak.Middleton

	Fixed ForcePositionUpdate() not calling CheckJumpInput(). Added "p.NetForceClientServerMoveLossPercent" cvar to simulate loss of client->server movement RPCs (without hosing the rest of networking).

	- 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

	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.

	[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 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

	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

	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.

	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.
