Downloaded. Thank you very much! Those preview work lights sound great!

I'm not familiar with the notion of a Blackbody node. Is that something in the studio lighting that I just downloaded? Or is it something else?

One of the things I am is a retired studio owner and portrait photograher. Lights, cameras, softboxes, all that stuff. And I'm very much a lighting nut. So if Blackbody nodes give you a more realistic rendering, then I defnitely want to hear more!
