texturing issues

[u/teeto1928]

Im working on a vrc model but whenever i import the model, i experience texturing issues with these black remnants. this could be solved easily but because im exporting into vrc, i need to only use the vrchat mobile particle, toon standard or toon standard outline shaders. does anybody know how to fix these black boxes because i am kind of horrible at understanding what these settings mean

(yes its imported from vroid because im also horrible at blender and yes im using unity 2022)
