I haven't looked deeply in the code vp_build but i will take a deeper look to it. I think we should really use somethings that mesa provides as futur drivers will probably use such things. >3. Number of temps exceeds 32 in some cases. I astonished by the number of temp reg, there is a waste some where i think. I have little bit stoped my effort as it seems they are issue with closed driver & vertex program (ati one) not providing correct values in some case (really boring to debug). But i will try to finish it at least it could be a good test program... Jerome Glisse ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
