I''m trying to make an indexed cube with only 8 vertices, but I''m stuck because I can only put one normal with each vertex (when there should really be 3). Is there a way to use different normals w/ the same position data or should I duplicate (triplicate!) the position data to get new copies of the normals? Thanks, Riley

you should triplicate the positions.

You will need to duplicate, or use another lighting method (VS/PS)
