CSN0309 Posted February 23, 2011 Share Posted February 23, 2011 Hi guys~~~~~ I Think this should be a very simple problem,,but i couldn't fix it~~~~ i got a very simple shader which can make the "top" surface of geometry as red,,,very simple. but my problem is when i rotate this geometry, the red area can not keep its original position. I have add the Transform node inside my shader, but it doesn't help.... can anyone tell me why???Normaltest.hipnc thanks Quote Link to comment Share on other sites More sharing options...
3__ Posted February 23, 2011 Share Posted February 23, 2011 see attached. saved the normal to an attribute before the transformation, then used that attribute in the shader instead of normal. Normaltest2.hipnc Quote Link to comment Share on other sites More sharing options...
