see here for a picture of of the problem http://members.nbci.com/_XMCM/mybollux/extensions/nv_evaluators/nv_evaluators.html

basically everything works fine when the EVAL_ORDER is set to 2-7. but when ive got the it set to 8 half the time its ok + half the time it goes ass over tit, all depending on the mapParamater values. im pretty sure this is a bug in the drivers(10.80) btw no error messages are reported

Can you be more specific about what the problem is? Is it just the lighting that is problematic, or the geometry also? Are you using AUTO_NORMAL? What level of tessellation does it begin at? Integral tessellation only, fractional only, or both?
