So I stumbled across this and I've been wishing for some time that there was some way we could layer multiple animations and choose what animation or how much that each body part plays.
This took me by surprise though....I never thought anything like this was possible but I stumbled across this Maya Plugin.

If Reallusion could pull something like that off it would be a really Amazing feature ^
