I am now at 48 hours on this render. Precalculation has finished. It is now rendering. If anything the render process is even slower than the precalculations. The big hold up is the water. I think it is the reflection of the water. There is a bump map, but no displacement. The render over the water advances about 4 16-pixel buckets at a time, and each advance takes almost an hour. So far the render with IDL (and with one shadow mapped light) is a little better than without IDL and with one light with Raytraced shadows, but the very small improvement is not worth 48 hours rendertime. Sigh.
