Not bad! Been busy with work lately, but when I last tried a different angle with the best settings from my last posting, I found the translucency affected practically every part of the body facing the camera, reguardless of thickness. Either I'll have to try another setting, or create a map for translucency.
I'm guessing it's possible that C5 can't determine the amount of translucency relative to local thickness, but I don't know for sure yet.
