That is superb! I've been working on rendering medieval church sites too (I'm an archaeologist). Can you tell me how you modelled the tracery? I've been searching for low-poly ways to model tracery for years now and yours is some of the most satisfying I've seen, from a geometry point-of-view especi...

Thanks for your quick and helpful comments, everyone. I've solved the problem. It was indeed a problem of coplanar faces. Vectorworks doesn't seem to know or care about normals or coplanar faces and exports a slightly problematic mesh. The answer seems to be to turn all 3d elements into generic soli...

Below is my first Indigo render. It's a WIP interior of a church, obviously. No materials other than diffuse white right now. However, I think it's obvious that I've got some trouble with my mesh. Any suggestions? The geometry was generated in Vectorworks, exported to C4D and then again with Cindigo...
