I’ve been trying to render this test of some simple glasses and I cannot for the life of me figure out what’s wrong. It looks as though “set smooth” is being ignored, although I do have it selected. I’ve also added a subsurf modifier to level 3.
I thought maybe that I didn’t have enough geometry, as the first one I set “spin” to 25. So I tried it again and set spin to 85. More than enough!
What else could it be?? Yes - normals are just dandy.
I thought might be some kind of error with Indigo or the Blendigo exporter, but I’m getting the same errors in YafRay. Which seems to indicate that the problem is with the mesh itself.
