Hi, i need help! I used Maya to make these stilletos, everything looks fine, but the inside part of the shoe... Why is it transparent??? It really bothers me and bugs me, I cant sell product like this. When I was exporting to fbx_dae and its said this warining While reading or writing a file the following notifications have been raised. Warning: Null not supported by COLLADA.

The node transforms will be saved. My question is, is this normal to be transparent inside?
