Here's Antonia with two levels of Catmull-Clark subdivision applied within the exporter, which brings her up to approximately 640k quads or 1.28 million triangles (not counting the clothing, hair and floor). Export time was 3 minutes, import into Lux with preprocessing approximately 2 minutes, render time 2 hours. The .lxo file was 89 megabytes large.

If you're wondering if I'm crazy to implement a subdivision algorithm in Python within the exporter, have a look at the images I posted on page 24 (second post from the top).
