Alright, I have never seen this issue with any avatar model ever in unity. 

So the base mesh is about 46k polys with some added stuff to it. I then attach these boots to the armature at the lower leg (the boots are about 2k polys) and then suddenly....the vrchat sdk is detecting like 2 billion polys on the model.
What the fuck is happening here? how can I fix this? I know the boots are very low poly I went back into blender to double check.
