@csehz Thanks! I appreciate the comment, and yes, I think the right amount of atmosphere/fog/dust is one of the hardest things to capture in any “clean” render.
@silentheart00 Thanks for the link. It covers the rudimentary info I was talking about. What I don’t have much sense of is what the radius settings are doing under the hood. For this render I played with them a bit. I got some really interesting banding in the light that was an appealing effect, but didn’t in any way match what I was attempting. I may check out those links at the bottom later though, even though they aren’t for Blender.
@theluthier Ha. As I told Katerina, I have no knowledge of interior design. The colors looked fine to me, but it’s entirely possible that any designer anywhere would unanimously agree they are awful. I picked them somewhat arbitrarily, so I will be sure to do some research next time and mimic someone else’s color scheme.
