Hi Cervantes, normals are really just a property of vertices, not faces. The way to get flat faces with the fixed-function pipeline is to duplicate the vertices and give them different normals. If you're using (or prepared to use) vertex shaders, you could attach your second normals to another stream, and write a vertex shader to choose the right normal. How you do this is application dependent, but to emulate the standard lighting calculations is well documented. -J ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
