I really loved the models, but some things are a bit broken, Fang's model in his Boss Battle is bugged, I mean, his battle animation is bugged, but other than that it's great. I hope that in the future you, or the team, makes a model of the classic shadow and the junio sonic, it would be really cool.
interpolation still exists, specially to help on frames that really lack and crave for those extra frames! UwU
