If you use ActorCore motions, you'll need to select the target character within the Download Settings if you want to start downloading animations. Afterwards, you can use the Auto Setup plugin provided by Reallusionto bring the character along with its motions to Unreal Engine.

If you want to use "your own set" of motions on an ActoreCorecharacter in Unreal, you can take a look at this video to learn about the motion re-targeting process. The mapping file mentioned in the video can be downloaded here: https://file.reallusion.com/Retarget.zip





1. Open the character's Skeleton, and go to Retarget Manager panel.

Select Rig to Humanoid Rig.
