i hope someone can help.
I use to export architectural models from autocad to blender (cvs) through a 3ds file, but my last works show many errors when rendered in yafray, some sort of geometry error that cause triangles missing in rendered images (not corresponding to mesh triangles anyway). blender internal renders are working as expected. i include an example. can someone give me a good suggestion? i tried converting 3ds to obj before importing in blender and tried as well to increase the value of FACETRES variable in acad, but results are the same.
