Quote - I figured you could use a loaded sphere for a gradiant sky, but isn't there some way that could be done node wise with the background, so transparency is retained for postwork?

 

I'm confused by that seeming contradiction. Either the background pixels are filled or they're not filled. How would you expect the sky to render but still be transparent?

If you intend to composite your figure onto a background in postwork, why would you want it to render a background?

Compositing with a sphere or a background square is going to fill every pixel and give you the background you want without any postwork, right? Why would you want to composite that with something else?

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)
