Do you mean boolean (i.e. -1/0), or -1/1, or 0/1, or something else? As is, FACE is supposed to be -1.0 or 1.0. NVIDIA hardware outputs -1 and 0 (i.e. boolean). -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
