Hmm, it seems the model is already glitching in 3D Max, so it didn't even make it to the export stage.
I don't know much about exporting animations. As far as I understand, Hanik loads the animations onto the model with a skeleton and then converts all of that into a gr2 file, excluding everything except the animation, but I might be wrong.
Why (if that's the case) load the animation onto the model with a skeleton if I sent you the ready-made files...?
