I’m trying to import a USD file that has multiple animations associated with it. Despite all the ani showing up in the list of prims to import, only the first animation gets converted to an animation sequence asset in the Content drawer. In the USD stage window, I get similar behavior. Only the first animation seems to be available to the sequence that USD stage is using. I have viewed my USD file in USD view, and I can see all the animations in there connected to the skeleton. Any ideas?
AFAIK several animations linked to a single skeleton is not something that will work on import.
You might have to separate animations in different USD files and point to the already imported skeleton when importing in UE.
Is your USD file something you could share with us?
