#lockdown Nick.Penwarden #rb none ========================== MAJOR FEATURES + CHANGES ========================== Change 3209340 on 2016/11/23 by Ben.Marsh Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h. Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms. * Every header now includes everything it needs to compile. * There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first. * There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h. * Every .cpp file includes its matching .h file first. * This helps validate that each header is including everything it needs to compile. * No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more. * You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there. * There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible. * No engine code explicitly includes a precompiled header any more. * We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies. * PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files. Tool used to generate this transform is at Engine\Source\Programs\IncludeTool. [CL 3209342 by Ben Marsh in Main branch] |

MAJOR FEATURES + CHANGES
==========================
Change 3149443 on 2016/10/03 by Max.Preussner
MediaAssets: Better parameter names for MediaPlayer BP functions
Change 3149756 on 2016/10/03 by Max.Chen
Sequence Recorder: Set some settings to be clamped at 0 (sequence length, recording delay, audio gain, audio input buffer size, nearby actor recording proximity)
#jira UE-35233
Change 3149795 on 2016/10/03 by Max.Chen
Curve Editor: Set tangent to user when flattening or straightening tangents only when the tangent mode is auto and the interp mode is cubic.
#jira UE-36734
Change 3150378 on 2016/10/04 by Max.Preussner
PS4Media: Made video buffer sizes for file and HLS sources configurable (UE-36807)
#jira UE-36807
Change 3151414 on 2016/10/05 by Max.Chen
Sequencer: Fix case where restoring the last view target was getting skipped. It should always restore if the camera object and the unlock if camera actor object is null.
#jira UE-35285
Change 3152038 on 2016/10/05 by Max.Preussner
UdpMessaging: Code & documentation modernization pass
Change 3152471 on 2016/10/05 by Max.Chen
Cine Camera: Don't enable/disable actor ticking based soley on actor tracking since actor ticking is needed for other purposes. Instead, always enable actor ticking and only update actor tracking on tick if necessary. This fixes a
bug where the cine camera actor won't tick if you hook in event tick.
#jira UE-36625
Change 3152692 on 2016/10/05 by Max.Preussner
Messaging: API code & documentation modernization pass
Mostly removed shared pointer/ref typedefs as they prevent forward declarations and increase include complexity.
Change 3153824 on 2016/10/06 by Max.Preussner
Messaging: Renamed IConnectionBasedMessagingModule to ITcpMessagingModule and moved it into TcpMessaging
I recommend that we refactor this API. The dependency should be reversed, i.e. instead of AndroidDeviceDiscovery depending on the TcpMessaging plug-in module, the Engine should provide a central registry that device discovery
modules can notify, and that message transport plug-ins can register with and listen to OnConnectionAdded/Removed events etc. That way it supports an arbitrary number of transport plug-ins, and the Engine is not coupled to any of them. This
functionality is not necessarily related to messaging, and the Messaging API is transport agnostic anyway. I'll think about this some more.
Change 3153826 on 2016/10/06 by Max.Preussner
Messaging: Removed remaining typedefs in IMessageTracer to enable forward declaration and reduce include dependencies
Change 3153857 on 2016/10/06 by Max.Chen
Sequencer: Set snap time to dragged key on by default.
Change 3153980 on 2016/10/06 by Max.Preussner
SessionServices: Removed typedefs; code and documentation modernization pass
Change 3154313 on 2016/10/06 by Max.Chen
Sequencer: Set the paste keys time to the current time, rather than the mouse time.
Change 3154332 on 2016/10/06 by Max.Chen
Sequencer: Remove click to rename shot functionality in the shot thumbnail. Added rename shot to the shot context menu.
Change 3154377 on 2016/10/07 by Max.Chen
Sequencer: Add ability to step to beginning and ends of sections/shots using the hotkeys: , and .
Change 3154788 on 2016/10/07 by Max.Chen
Sequencer: Fix offsets that created when moving multiple sections. The offsets were being created because section bounds were being generated for all sections except for the current section. Instead, they should be computed for all
sections except for any that aren't being moved.
#jira UE-29152

========================== MAJOR FEATURES + CHANGES ========================== Change 2837601 on 2016/01/20 by Thomas.Sarkanen Sequencer: Exposed bool, byte, event, fade, float, slomo, and visibility section keys in context menu Change 2840895 on 2016/01/23 by Thomas.Sarkanen Sequencer: Moved key proxy handling from section into key area; added support for grouped keys; exposed color properties in context menu. Change 2901092 on 2016/03/09 by Thomas.Sarkanen Sequencer: Fixed ensure() and crash when exiting PIE & then playing back in editor Made sure that instances that are playing that have active montages can re-connect to a playing montage if it is already active. We dont stop/start preview/non- preview playback when switching modes right now so I've just made the system robust to the switch when playing back animation. Ensured that instances are kept up to date by hooking into EndPlayMapDelegate. This fires slightly later than OnEndPIE, so it allows us to pick up when instances have been deleted from the world. OnEndPIE is fired before the worlds are shutdown so instances can still be bound to valid (but nearly dead) actors at this point. #jira UE-27898 #jira UE-27899 Change 2901159 on 2016/03/09 by Chris.Bunner Allow EXR frames from SaveHighResScreenshot to be uncompressed (r.SaveUncompressedEXRFrames). Change 2903123 on 2016/03/10 by Max.Chen Sequencer: Add snapping for the in/out range. Change 2903126 on 2016/03/10 by Max.Chen Sequencer: Fix split and trim for cinematic shot sections so that the start offset value is set. Change 2903132 on 2016/03/10 by Max.Chen Sequencer: Create camera here and set it as the current camera cut. Change 2903138 on 2016/03/10 by Max.Chen Sequencer: Improve mechanism for adding objects to Sequencer. Hold down shift while dragging from content browser to add as a spawnable. Hold down ctrl while dragging from content browser to add as a possessable. Change 2903143 on 2016/03/10 by Max.Chen Sequencer: Add 4k to movie capture dialog. #jira UE-28147 Change 2903157 on 2016/03/10 by Max.Chen Sequencer: Pop out of locked camera when popping out of the sequence. #jira UE-27662 Change 2908097 on 2016/03/14 by Andrew.Rodham Sequencer: Added default viewport type onto the viewport types menu - The activation command for a given viewport type no longer toggles it if it's already active, it will just do nothing. - Switching back to the default viewport type can be achieved with SHIFT+D Change 2911869 on 2016/03/16 by Max.Preussner Editor: Caching device proxy manager, so the UI doesn't constantly poll for the TargetDeviceServices module Change 2917943 on 2016/03/22 by Thomas.Sarkanen Sequence Recording: Added "Record New Sequence From Current Player" to sub-sequence track menu This option is only available in PIE. When selected it primes a new seciton for recording against the pawn that is currently being controlled by the player. Change 2917946 on 2016/03/22 by Max.Chen Sequencer: Automatically add and attach a cine camera when dropping a crane or rail. Change 2917954 on 2016/03/22 by Thomas.Sarkanen Fix anim dynamics going crazy on time skips Added new API to FAnimNode_Base: NeedsDynamicReset and ResetDynamics. This allows nodes that subscribe to this interface to be reset on teleport/time skips. Call through to ResetDynamics on zero timestep (ie. skips) in the preview path in Sequencer. Change 2917961 on 2016/03/22 by Frank.Fella Sequencer - Sequencer - Update the color track code to match the behavior in matinee, also remove empty light color tracks from the sequence, and add a missing particle parameter track. Change 2917984 on 2016/03/22 by Max.Chen Sequencer: Fix crash on deleting object binding nodes multiple times. Change 2917986 on 2016/03/22 by Max.Chen Sequencer: Fix if adding multiple camera cuts at the same time with the same duration as an existing camera cut. The camera is replaced in this case. Change 2917994 on 2016/03/22 by Jeff.Farris Support for scene depth picker. Used for focus depth sampling in cine cams. Change 2918003 on 2016/03/22 by Max.Chen Sequencer - Fix selection issues related to keying an undo by moving the selection clear on rebuild to after the tree selection state has been cached by path. Change 2920371 on 2016/03/23 by Max.Preussner UnrealEd: Added a file import path that doesn't load the entire file into memory prior to importing UFactory::StaticImport will now call FactoryCreateFile for both text and binary files. The default implementation will load the file into a buffer/string and call FactoryCreateBinary/FactoryCreateText to preserve legacy behavior. New factories may override FactoryCreateFile to perform their own file processing instead. Change 2923359 on 2016/03/25 by Max.Preussner UnrealEd: Refactored out StaticImportObject code into ImportObject Change 2924887 on 2016/03/28 by Jeff.Farris Sequencer: Camera Anim and Camera Shake tracks now support PostProcess changes in the CameraAnim Change 2927283 on 2016/03/30 by Max.Chen Sequencer: Fix crash resetting default in audio track in sequencer. Fix audio track rename when adding another audio. #jira UE-28836, UE-28859 Change 2928290 on 2016/03/30 by Max.Preussner ContentBrowser: Disabling 'Show in Explorer' context menu option for newly created/unsaved asset(s) Change 2928480 on 2016/03/30 by Max.Preussner AssetTools: Added built-in type category for Media assets Change 2928498 on 2016/03/30 by Max.Preussner AssetTools: Sorting asset type categories alphabetically Change 2932326 on 2016/04/04 by Frank.Fella Sequencer - Add "paste from matinee" support for audio tracks, and add volume support to audio sections in sequencer. Change 2933917 on 2016/04/05 by Max.Preussner Core: Added microseconds support to FTimespan Change 2933920 on 2016/04/05 by Max.Preussner Sockets: Simplified socket timeout assignments Change 2935434 on 2016/04/06 by Max.Chen Sequencer: Deselect possessable before converting it to a spawnable and deleting it. Also, make sure the newly converted spawnables are selected. This fixes a bug where the transform gizmo remains after adding a spawnable. Also, consolidate code for adding possessables to sequencer so that the newly added possessable node will be selected in the widget tree. #jira UE-28215 Change 2935590 on 2016/04/06 by Jeff.Farris Made crane rig preview mesh at the tip move as expected and appear in a reasonable place. Change 2936082 on 2016/04/07 by Max.Chen Sequencer: Attach should use default attach component of the actor if it exists. This fixes a bug where trying to attach to a camera crane rig attaches to the proper component. Change 2936118 on 2016/04/07 by Max.Chen Sequencer: Adding crane/rail with shift now adds the crane/rig as a spawnable and the attached cine camera as a spawnable. An attach track is created for the cine camera spawnable. #jira UE-28308 Change 2937226 on 2016/04/07 by Max.Chen Sequencer: Add invalidation when levels are added or removed.This fixes a bug were if you have a level sequence open and then add a sublevel that the level sequence operates on, it correctly updates the actors from the new sub level. #jira UE-27595 Change 2937263 on 2016/04/07 by Frank.Fella Sequencer - Changed the matinee to sequencer conversion tools so that curve keys set to "clamped auto" import as user tangents since we don't support clamped auto in sequencer. Change 2937273 on 2016/04/07 by Max.Chen Sequencer: No longer experimental/betal and now enabled by default. #jira UETOOl-625 Change 2937694 on 2016/04/08 by Max.Chen Curve Editor: Separate out input and output snapping. #jira UE-27209 Change 2937852 on 2016/04/08 by Andrew.Rodham Sequencer: Spawnables no longer use generated classes - Spawnables now store a template actor instance, rather than a generated class - All relevant code has been converted to use this new approach - Spawnable defaults are now harvested directly from any spawned instances when the movie scene is saved, or when the object is de-spawned. We only do this for spawnables *in the currently active sequence instance*. This approach ensures that instance components and other properties persist. - Currently we don't mark the package as dirty when the defaults are changed. This needs to be addressed. - Some fixes have been made to AActor and Actor Iterators to ensure that actors not contained within a level do not crash. - Spawning optimisations to follow Change 2937956 on 2016/04/08 by Max.Preussner Sequencer: Added selection range commands to general toolbar menu Change 2937981 on 2016/04/08 by Max.Preussner Sequencer: Refactored GetKeyHandles to take a time range for filtering keys Change 2938007 on 2016/04/08 by Max.Preussner Sequencer: Implemented selection range key selection Change 2938184 on 2016/04/08 by Max.Chen Sequencer: Find in Content Browser is now in the top level menubar. #jira UE-21598 Change 2938665 on 2016/04/08 by Frank.Fella UMG - Add support for material animation. Change 2939048 on 2016/04/10 by Max.Chen CineCamera: Change current position on rail to normalize position. Change 2939067 on 2016/04/10 by Max.Chen Sequencer: Add paste color from matinee Change 2939587 on 2016/04/11 by Andrew.Rodham Sequencer: Fixes to spawnable rework - Removed commented out code. - Fixed particle system components not disabling auto activate. - Instance Components are now correctly registered on spawn. - Removed ability to set the editable flag on actors in favor of a delegate assigned to SActorDetails to disable property editing on actors spawned from outside of the currently focused sequence. Change 2939666 on 2016/04/11 by Andrew.Rodham Sequencer: Fixed active sequence ID not being set on creation Change 2940663 on 2016/04/12 by Andrew.Rodham Sequencer: Spawnable object templates now always have the RF_ArchetypeObject flag #jira UE-29337, UE-29339 Change 2940742 on 2016/04/12 by Thomas.Sarkanen Improvements to sequence recording API Sequence recording is now more extensible. Moved the majority of recorders into a seperate module. Cleaned up recorder API, removed bRecord that was only really used once. Added factory class as a modular feature that allows users to register and implement their own recorders. Recorders can supply their own settings classes. These are incorporated into the UI via a details customization so they appear to be seamlessly integrated. Exposed components to record as an advanced setting. Users can use this to gate the components and actors that are recorded. #jira UE-28850 - Update sequence recording API for better extensibility Change 2940828 on 2016/04/12 by Max.Chen Level Editor: Clear the camera preview if the level viewport is locked to the same camera. #jira UE-27489 Change 2941090 on 2016/04/12 by Frank.Fella Sequencer - Fix inconsistencies with the level visibility track. + Add an option to update a track instance when it stops playing due to it's parent movie scene being deactivated as a sub-scene. + Reset level visibility state when the section ends, or when it's parent subsection ends. Change 2941427 on 2016/04/12 by Andrew.Rodham Sequencer: Fixes for recorded dynamic components - Dynamic components are now named uniquely within their owner actor, and are no longer re-bound to new object tracks when detached/re-attached - New dynamic components are created every time a new component is detected on an actor, regardless of whether it was once attached before. This affords recording externally managed components from a component pool. - Section recorders for components that are no longer attached to the actor are now disabled correctly. Change 2941760 on 2016/04/12 by Max.Preussner Editor: Setting up correct material expresions when creating material from normal map texture Change 2941819 on 2016/04/13 by Max.Chen Sequencer: Fire named events in all sublevels. #jira UE-28843 Change 2942052 on 2016/04/13 by Andrew.Rodham Sequencer: Fixed not being able to add dynamic material parameter tracks to spawnables when the object is not spawned #jira UE-24287 Change 2942223 on 2016/04/13 by Max.Preussner Editor: Using built-in function to assign sampler format Change 2942833 on 2016/04/13 by Max.Chen Sequencer: More copy matinee helpers. - Make some sections infinite. - Fix FindPossessableObjectId - Expose FindGroupByName Change 2942944 on 2016/04/13 by Max.Chen Sequencer: Fix anim copy so that it doesn't create an animation clip longer than the next clip's start position. Change 2943313 on 2016/04/14 by Max.Chen Sequencer: Initial matinee to level sequence asset converter. Right click on a matinee actor in the level and choose "Convert to Level Sequence" Current supports: - movement tracks - generic property tracks - particle tracks - anim control tracks - event tracks - audio tracks - visibility track - director track (fade, slomo, camera cuts) Possible todos: - Relative scale3D - Option to create spawnables instead of possessables - Create shots per director track camera cut instead of a direct translation to the camera cut track #jira UETOOL-467 Change 2943596 on 2016/04/14 by Andrew.Rodham Editor: Fixed placement mode scrollbar visibility not working for custom content #jira UE-27191 Change 2943651 on 2016/04/14 by Max.Chen Sequencer: Invalidate the audio waveform when the source changes. #jira UE-29394 Change 2943674 on 2016/04/14 by Max.Chen Sequencer: Store/restore playback state when rebuilding. #jira UE-29452 Change 2943993 on 2016/04/14 by Max.Chen Sequencer: Convert slot name from matinee to level sequence. Change 2944156 on 2016/04/14 by Frank.Fella Sequencer - Fix undo when moving items into folders, and when deleting folder. #jira UE-27368 Change 2944227 on 2016/04/14 by Max.Chen Sequencer: Show curves in the curve editor if one of the parent nodes is selected. For example, if Location is selected, show Location.X, Location.Y, and Location.Z Change 2945057 on 2016/04/15 by Andrew.Rodham Editor: Fixed placement mode scrollbar visibility not working for custom content #jira UE-27191 #lockdown nick.penwarden [CL 2945551 by Max Chen in Main branch] |

Copying //UE4/Dev-Sequencer to //UE4/Main
========================== MAJOR FEATURES + CHANGES ========================== Change 2875025 on 2016/02/20 by Andrew.Rodham Sequencer: Cinematic viewport improvements - Added optional letterbox overlay (defaults to 2.35:1) - Added ability to change safe frame colors - Added selected tracks' keys to the transport range - Added buttons for jumping between selected tracks' keyframes on the transport controls - Removed black padding around the viewport where possible - Added ability to specify whether a combo button/menu anchor should close when its parent receives focus - Separated logic of FGroupedKeyArea into FSequencerKeyCollection, so it can be used independently - Added playback range to the viewport frame numbers - All frame numbers are now spin boxes #jira UE-26429 Change 2875026 on 2016/02/20 by Thomas.Sarkanen Added console commands for recording sequences Changed plugin to a developer plugin so we can load it when the editor is in -game mode. Added Exec commands. Added some more logging to help diagnose problems when using commands. Added loading/saving of config for recorder settings (stored in Editor.ini). Also disabled controls in recorder window when recording. Added auto-saving of assets when in non-editor modes. Moved animation settings from UnrealEd to Engine module. Change 2875036 on 2016/02/20 by Max.Chen Sequencer: Call RedrawAllViewports instead of RedrawLevelEditingViewports. In particular, this fixes some update issues when editing values in the key editors. #jira UE-26960 Change 2875046 on 2016/02/20 by Max.Preussner Sequencer: Fix so that clicking on UMG Animations doesn't dirty the scene. #jira UE-26249 Change 2875047 on 2016/02/20 by Max.Chen Sequencer: Add option to toggle display of channel colors/lines. View->Channel Colors Change 2877138 on 2016/02/23 by Max.Chen Sequencer: Select corresponding track node when selecting key or section. Removed active/inactive selection since it was only being used in deletion and the rules for deletion are now dependent upon what is selected - delete keys and sections before deleting outliner nodes. Change 2877143 on 2016/02/23 by Thomas.Sarkanen Added new math function: WindRelativeAnglesDegrees Given two angles in degrees, 'wind' the angle in Angle1 so that it avoids >180 degree flips. Good for winding rotations previously expressed as quaternions into a euler-angle representation. Change 2877147 on 2016/02/23 by Thomas.Sarkanen Added the ability to import sequencer transforms from the root node of an animation sequence Intended for use after re-importing animations from DCC tools. Available in the right-click menu for transform tracks. Also added FindTrackBinding to UMovieScene so track bindings can be recovered from tracks. Change 2877163 on 2016/02/23 by Max.Chen Sequencer: Add option to create keyframe sections as infinite. Sequencer defaults to true, UMG defaults to false. Change 2877165 on 2016/02/23 by Max.Preussner Sequencer: Drawing vertical position lines when dragging keys Change 2878748 on 2016/02/23 by Max.Chen Curve Editor: Switch curve type to user when flatting or straightening tangents. #jira UE-27277 Change 2878799 on 2016/02/23 by Frank.Fella Sequencer - Add folders support to the outliner. Change 2880769 on 2016/02/24 by Andrew.Rodham Sequencer: Added ability to override runtime spawnable ownership in sequencer - This is exposed as an option on spawnables "Keep Alive Outside Playback Range (In Sequencer)" - Enabling this will stop spawnables from being destroyed when scrubbing outside of the playback range #jira UE-27205 Change 2880770 on 2016/02/24 by Thomas.Sarkanen Sequencer: Added countdown and recording indicator display when recording Also fixed extra popups added post-PIE when animation recordings auto shutdown. Change 2880782 on 2016/02/24 by Max.Chen Sequencer: Snapping now also uses the current time as a possible snap time. #jira UE-26306 Change 2880793 on 2016/02/24 by Max.Chen Sequencer: Add +Animation to Animation track so that it's consistent with all other tracks that have a + button. Change 2880812 on 2016/02/24 by Max.Chen Sequencer: Fix adjusting the leading edge of a shot section so that it cuts into the shot rather than adjusts the start time. #jira UE-26306 Change 2881624 on 2016/02/25 by Andrew.Rodham Changing shader version GUID to fix corrupt shaders in ddc Change 2882408 on 2016/02/25 by Thomas.Sarkanen Asset/actors stored in TLazyObjectPtrs can now reference game content from engine This is a legitimate use case as lazy object ptrs are designed to reference assets/actors cross-domain.
