I have a model of a dog dish made in blender and exported to cal3d. In blender I set the 'Twosides' flag and blender will display the texture on the face and backface of the model. I was told that many game engines have some functionality to replicate this feature in blender. Is there such functionality for cal3d models so I can have a textured face and backface?
CS unfortunatelly doesn't support this. You'll have to manually duplicate the faces for now.
