    possible bug with nv_evaluators

    see here for a picture of of the problem http://members.nbci.com/_XMCM/myboll...valuators.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

    Re: possible bug with nv_evaluators

    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?
