What are the environment colours used in the Performer town demo? The mga driver special-cases all zeros and all ones, is this enough? The all ones multitexture case is broken in the r128 driver, and I'm wondering if I should just leave it as a software fallback for now. -- Gareth |

All ones / all zeros is enough to make performer town work. -Jeff |

Yes, the r128 is basically identical - all zeros with single texturing, all ones with a multitextured fallback (first unit computes Cf(1-Ct), second unit does Cf+Ct). It's just not working on the r128 at the moment. -- Gareth |
