HoloSuite Player Unreal - 4.1.0 Release Notes¶
New Features¶
Added AVV and OMS Player components for blueprints¶
Two new components have been added for AVV and OMS which allow their configuration directly using blueprints. The configuration options and functionality should mirror the standard Player actors. A number of nodes have been added that directly support this new component type and its event graphs.
Added new playback options for AVV clips¶
Two new options have been added for AVV clips to increase the range of playback operations available. These new options are found under the Playback heading:
Reverse¶
The Reverse option will cause the clip to start at its end frame and play in reverse. This can be used together with Loop and/or Ping Pong if desired.
Ping Pong¶
The Ping Pong option will allow the clip to play through, and then cause the clip to play in reverse once reaching the last frame. This can be used together with Loop and/or Reverse if desired.
Added new options to add AVV clips to the Sequencer¶
One of AVV’s main strengths is the ability to play large numbers of clips simultaneously in a scene. When trying to set up scenes with advanced playback control using the Sequencer, you would have to add every AVV clip individually - a task that quickly became tiresome when dealing with 50-70 players.
To address this, new options have been added to the Add Volumetric Video track operation, which allows you to add clips from the scene which are currently selected, or to simply add all clips that are in the scene. This will allow you to set up large scenes that use the Sequencer much more efficiently than before.
Improvements¶
Reduced AVV memory footprint¶
Improvements have been made to the handling of AVV assets which greatly reduce their memory use during playback.
Added texture double buffering for OMS playback¶
It was possible for OMS clips to experience occasional texture desyncs during playback, particularly under heavy load on the device. Double buffering has been added to eliminate this issue.
Fixes¶
Fixed OMS playback failing¶
A late issue had made it into the 4.0.0 release which prevented the OMS format from being able to play using the HoloSuite Player. This issue has been fixed and OMS files can now be used in the Player.
Creating Materials from OMS in Unreal Engine¶
Fixed an issue where the user was unable to generate lit/unlit materials from OMS files with the Unreal Engine HoloSuite Player using the context menu in the Content Browser.
Crash when HoloSuite Player is nested in Plugins folder¶
Fixed an issue where Unreal Engine would crash when trying to import the HoloSuite Player when it is nested within the Plugins\Marketplace folder.
Known Issues¶
OpenGL playback is not functional¶
If trying to generate a build using OpenGL for rendering, both OMS and AVV formats will present issues. OMS actors will not correctly animate, and AVV actors will cause the application to crash after launch. These issues will be addressed in a future update.
