I tested my model import I'm working on and the polygons exploded all over the stage and some polygons had static-like textures and others had almost-perfect metal textures.
I pretty sure it's not the model or anything, it was working fine before in game (well, minus the texture and shader problems I was trying to fix).
The only things I changed from my last ingame test were (using the latest BB): I changed the textures from CMPR to C18 I changed the auto-metal option from False to True I exported the model as a .mdl0 and re-imported it (I also assigned the expressions to their respective visibility bones)
