Ah, sorry - I've misread your message. I'd suggest doing animation export in a different (more correct) way to get 1 psa containing all character's animations.
Watch the video:

Relevant part about animation export starts at time 15:00, but I'd recommend watching the full video - it is FULL of information.
Thank you, gildor. The "find animation" export method you directed is very useful, which makes the resources very neat, and "PSA" is also integrated. I will use this method to export in the future.
But I still want to ask if "actorx importer" can add the function of opening multiple PSA at one time? At present, I have many separate PSA. Since the game has been deleted, I can't export it again. I can only open all PSA repeatedly in 3DMAX. If I can open more than one PSA at a time, it will become very efficient. Is it possible to achieve this?
