Trying to enable backface culling

Hi all !

I have a scene with a mesh model (c3b) with 3 materials… two of them must have “two faces” (backface culing) but the exporter don’t seems to export this information to c3b format.

I found a CULL_FACE_SIDE_FRONT_AND_BACK on Material definition, but I dont know how to use it.

Anyone can helpme?

really? no one?
