    5.0

The Unreal Live Link plug-in makes it possible to stream animation data from Maya to Unreal in real time. Whether you’re working between the two tools in a virtual production environment or building your next game, you can now work on character assets in Maya and see previews of your work reflected immediately in Unreal, as you make changes. 

 

Update October 20, 2023.

Unreal® Live Link for Autodesk® Maya® for UE 5.2 has been recompiled to work with Unreal Engine 5.2. It will NOT work with Unreal Engine 5.1 or earlier, see links below. It works with Autodesk Maya 2022, 2023 and 2024.

 

Note: Due to changes outside of our control, there is a known issue with minor lag occurring when animation is updating in Unreal Engine while scrubbing the timeline in Maya. The workaround is to scrub the timeline in Unreal Engine and the animation will update in both applications without any lag.


Update March 1, 2023

Unreal® Live Link for Autodesk® Maya® for UE 5.1 is a new version of the Live Link plugin that has been recompiled to work with UE 5.1. It will NOT work with older versions of Unreal Engine, see links below.


Features include:

  • Asset Filtering - Easily find Unreal Engine assets and sequences with a new search and filter options.
  • Animation Sequence Filtering - Only sequences related to selected skeletons in the Live Link UI are shown to help you make selections faster.
  • Link Settings Saved - Links set up in the Live Link UI are saved with your Maya scene and reloaded when you reopen the file saving you time by not having to redo all your links.
  • Addtional Camera Attributes supported - Addtional camera attributes for Unreal Cinecamera Actors and Camera Actors are supported such as Aperture, Focal Length and more.
  • Dual installer - The Unreal Live Link for Maya installer installs both the Maya Live Link plugin as well as the Maya Unreal Live Link plugin in one single installer
  • New UI Layout - The UI has been updated to include features like Sync Time, Pause Character Animation Streaming and the new Asset Linking functionality
  • Asset Linking - Assets in Maya can be linked to assets in Unreal allowing animations to be pushed directly to the engine.
  • Bi-Directional Playheads - Timelines in Maya and Unreal are synchronized and the playhead can be manipulated in Maya or Unreal
  • Creation of Unreal assets directly in the Maya UI - Blueprint Instances, Lights, Cameras and Level or Animation sequences can be created directly through the Maya UI
  • Character Streaming can be paused - Streaming character data can now be paused making it easier when working with long sequences or complex skeletons
  • Bug Fixes
