Can I add my own .PMX files? Are Jiggle Bones supported?
Viewing post in Dance Dance Maker! - VR game for Oculus Quest comments
Jiggle bones should map to spring bones in VRM.
Here is some link I found how to covert mmd avatar to vrm format:

Anyway,It needs conversion if the avatar is not vrm format,before used in DDM.
