The Meaning of Life, the Universe, and Everything.
I wouldn't reccomend using McAnimator. IF your really desperate and don't want to code you can use Tabula and LLibrary which is a little bit easier. Otherwise you have to code them in. If you want to look for some examples, you could look into ModelBiped, or you could look at some example code I have used in my mods.BTW Your mod is not crashing because of the model. It is crashing because of the Proxy. When did you change your packages?
