Oh and I prototyped the "movable cloud prop". I used a bunch of poser spheres as props. Not the best shape, as the edges are too regular, but it serves to show the idea. By positioning an overlapping group of these, I can arrange the clouds in any shape I want.

B for Bagginsbill.

These movable clouds render really fast, because they don't need to go for miles, so I just used 10 samples, and they are always artifact free no matter where you put them.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
