brokenpixel Posted March 24, 2008 Share Posted March 24, 2008 hello all i have been having an issue with the H9 "brushed steel" material. i am getting grid patterns visible as reflections in my objects. if i set the U and V roughness to the same number the problem goes away - but with the default setting of U= .2 and V=.5 the problem persists. check out the attached image for a visual illustration of the problem. .hip file attached as well. the scene is composed of a simple .obj that is brought in and subdivided. is there something special that has to be done to set up this material to work properly ? does this have something to do with a reflection map that i am not setting up ? thanks in advance for any and all assistance. ++ scott brushed_steel_issue.zip Quote Link to comment Share on other sites More sharing options...
Jason Posted March 25, 2008 Share Posted March 25, 2008 Hi there, Unfortunately that shader will only ever look correct on a patch surface - NURBs or Mesh geometry types, or very carefully modeled quads- where the parametric s & t coordinates all run in the same direction. There is no way to supply your own uv coordinates to this shader and have the anisotropic highlights/reflections follow it correctly.
