Awsome can't wait to the release. And what do you mean with nifty trick actually??
The character won't have eye animations after, but this is what I found out.
-Export all your animations.
-Open up the Motionpac of the character you're porting over.
-Right Click, Replace All. Then find the folder.
-Delete everything else that isn't a .chr0 animation only in the part where the 300+ animations are. Do not do anything to the top part.
-Save As.
Please. I want to see some preview. Pictures, gif or videos.
Well I could make a quick video after I make the porting fixes and PSA the current attack animations I have done.
