Character Not Importing Vertex Weight Causing More Problems

Hey! I am trying to export character from Actorcore, both iclone and cc4 have the same issue. I export multiple Characters and Animations. When importing to unreal I select proper skeletal reference but when I compare bones, some are greyed out. “This bone is used by the current mesh, but has no vertices weighted against it”, causing improper use of animation.
I have tried exporting mesh and motion separately option, also exporting with animation already. Seems like its mostly the toes
Anyone have any ideas as to whats going on? Thank you, im pulling my hair out!!

Sorry posted late night, not sure if anyone saw, just kindly bumping :slight_smile:
