Hi there, i found an issue in GX_SetTexCoordGen2 . If you try to use it with GX_DTTIDENTITY it works fine, but if you try it with GX_DTTMTX0-20 even with an identity matrix loaded on those registers, it fails. The final result appears all white here (with the texture i tried, probably the texgen generated 1,1). Me and shagkur were talking about it this afternoon and indeed it seens like a libogc bug. I hope you guys can look and see if you discover anything because i couldn't and shag will only have time sunday or next week. Thanks you all.
