Hi, that's me. Turns out the clipping was being caused by the "Shake Control", the readme didn't say anything about that which is why I confused. it says FK>KKPE. 😭 My original post was mainly joking about the first post I made about it (So I turned ON FK) but had no clue you had to disabled BOTH FK and Shake Control. Here's a gif of both FK and Shake Control being off
https://gofile.io/d/JZ5UKj (Guys why are you downloading the gif file? You guys like lolis don't you. 😭) works flawlessly with no clipping. (Had to throw it in gofile because file to large big oof.) Anyways, you could maybe change or add to the README for the Magic Johnson to this. (This probably won't work for everyone, but it worked for me and a few others.)
This right here ^ But yeah, disabling both FK and Shake Control in Magic Johnson anim and it works flawlessly without any clipping no matter the character size.
