It appears that there is not a solid white background or skydome...

I attempted to use one of the studio backgrounds to create a white sweep rendering. Unfortunately, it did not work so well. Am I missing a solid white background or skydome? It seems as though this has been a request from multiple users, so I'm surprised this is not an option.

If you have any tips on how a true white background could be achieved, I'd appreciate the advice. Thank you!
