No released version afaik supports this on i965 (and certainly the driver reflects that in the supported extensions), though this should work in mesa git. If you need programmable pipeline on i965 with a mesa release version, try arb_vp/arb_fp instead. > As for the lighting, my entire scene looks washed out all the time. > Its almost like lights are being added after the texture component > instead of beforehand.

Not sure what's the issue, a simple example which fails would help (it may also be something which is already fixed). Roland </TT></DIV></BODY></HTML>
