Brilliant, David. Lightworks, it was.
Actually, it was a little spooky. Lightworks had the new texture maps, but in two or three instances it was still using the old texture maps for the preview window, like the kind of ghosts that can only appear in mirrors.
These were old textures probably dating back to the time when I briefly experimented with Lightworks and decided to get a life instead. Deleting the materials and re-creating them solved the problem.
Incidentally, I had one of your Digital Architecture People out for a special project the other day and took a look at the 3d script for fun. What an amazing bit of GDL that is!
Thanks again!
