I have a 2.5d character, rigged in Maya, imported into unreal. As it’s a 2d character his hands and mouth are animated not by movement, but by replacing the plane with a different image. A closed hand to a fist, for example.
I know visibility cannot be animated in .fbx, and I don’t want to add a bone for each separate state (would be super messy). Any idea how to work around this?
