Just find the bones on Bulbasaur that match the bones on Ivysaur and name the bones what the bones are named on Ivysaur by going into ModelData[0]>3D Models>[whatever Ivysaur's model name is]>Bones. Right click the bone you want to rename and click rename then type in the new name.
There's no guarantee the animations won't look awful though.
Yea ik tht but what i mean is to make it so that it won't have the walk/run glitch where it snaps back and so that the grab glitch and whatnot wont apply to it anymore.
Thats what i need. i also need the animations to look semi-normal.
