Well, I figured I'd be able to reproduce this error. It happened every time I tried to render. This was from a fresh install, where nothing had been changed. Yesterday I discovered that if I chose new window that the error didn't occur. So I was happy about that. So today I fired up DS and reset it so that it would render in the active window. But this time it renders with no error. Honestly, I can't explain it. I had no trouble reproducing the error until I changed to render to New Window. I didn't know there was a log file in DAZStudio. I'll take a look and see if there's anything useful there. I do have one other problem though...when I render, my character's eyes seem to disappear and the eyebrows and hair don't seem to be properly transmapped. It's like the transmaps were applied at 50% strength or something. Any ideas there? And the odd thing is the preview looks better than the render in this area. The eyes are there and the hair appears to be transmapped properly.
