Here's a render of Antonia with a test texture applied. Quads split into triangles; no further subdivision. The seams look correct. Time to try some more realistic skin... :laugh:

I had some artifacts supposedly due to wonky normals when I was still passing the quads through as they were. I don't see those problems anymore. So the normals seem to be close enough to what we need, at least for this kind of object.

I'm going to strip the quad-specific code from the exporter for now and export a pure triangle mesh. If and when Lux gets updated to handle quads correctly, I'll bring the quadrangle support back in a different way which will complicate the source code less.
