Hi Stefan, this thread helped me on the difficuties of implementing shadows in QC: http://kineme.net/Discussion/GeneralDiscussion/Shadows#comment-4245 I come from OGRE3D experiences and I studied a lot of shaders implementations for shadows, but none of them seems to be right for QC. The 3rd method mentioned by cwright still needs that you calculate yourself the texture-projection matrix to sample the depth-map in the right place. Do you know how to do that?
