I just updated my video card, and Lux seems far happier with it. This image hasn't had any post-work done (hence Brenna's shirt seems to be sticking into Garrick's chest), and I'm not entirely pleased with her skin tone, but this is a learning process and I'm learning. (I've left the background image out in an effort to focus on the figures.) For some reason, the renderer cropped the top of Garrick's head, even though it didn't look like that in Poser.  I can't say it's amazingly better than what I can do with Firefly at this point. I'll keep tweaking away and see what happens . . .
