TjQs Posted March 22, 2004 Share Posted March 22, 2004 This is supposed to be a standing seam metal roof on the back end of a building I'm working on. It's lit with only one light, but for some reason a diagonal shadow shows up in rendering. It appears where the flat surface behind got triangulated for modeling. Anybody know how to get it to go away? Link to comment Share on other sites More sharing options...
Videha Posted March 22, 2004 Share Posted March 22, 2004 hi do you model in autocad and render in?? do you use raytraced shadows ?? Link to comment Share on other sites More sharing options...
STRAT Posted March 22, 2004 Share Posted March 22, 2004 turn the shadow bias down to 0, or to absolute. Link to comment Share on other sites More sharing options...
Riehldeal Posted March 23, 2004 Share Posted March 23, 2004 Not being an advanced renderer and all yet, but is it possible that the material is just translucent enough to pull the reflection through the roof. Just throwing things out there:) Donnie Link to comment Share on other sites More sharing options...
TjQs Posted March 23, 2004 Author Share Posted March 23, 2004 Thanks for the replies fellas, but I tried shadow bias to 0, and the material is completely opaque. I did modeling in AutoCad, and b/c the shadow line lies on the triangulation I suspect its a conversion thing and not a mapping problem. Anyone?

STRAT Posted March 23, 2004 Share Posted March 23, 2004 sub select the faces and adjust the face smoothing properties then. could be the normals came in indifferently Link to comment Share on other sites More sharing options...
Fran Posted March 23, 2004 Share Posted March 23, 2004 Hi Tim, Try clearing the smoothing groups in sub-object mode. Link to comment Share on other sites More sharing options...
