How to overcome character's face rig completely breaking after the blender trip? #13

Open illieart opened 1 year ago

illieart commented 1 year ago

I had a great character, and I am currently coming to terms that once again, I may lose a lot of progress because one of the addons failed to export the altered character back into CC4 intact. Anybody knows about this bug after importing back from blender? Every time I move a part of the face rig in edit facial, something else moves. I try to move the mouth, the eyelash moves instead. When I pick an expression template, the mouth will not open and the TONGUE will pass through. Basically- the face is broken. HOW DO I OVERCOME THIS?

There's a strange bug in CC4 where it exports the facial expression blend shapes in the wrong order, causing them all to have the wrong names. It seems to be something to do with missing expressions or incorrect or corrupt facial profile data. I've only seen it once or twice and haven't been able to reproduce it since.

You should be able to fix it by re-applying a facial profile: CC4-extended or CC4-standard should do it. This will replace and rebuild all the facial expression blend shapes:

facialprofile

Or un-checking 'Import Facial Profile' when importing back into CC4 should give it a set of default facial expressions.

If that doesn't work then it is possible to recover the mesh using the mesh transfer tool. Which I originally made for transferring multi-res sculpted base meshes, but it is useful for recovering characters too:
