Regarding this image I posted yesterday: https://mastodon.gamedev.place/@aeva/113497645822172397
I experimented with blender's options for "ai" denoising and ultimately decide it was unsalvageable and left it off. I'm sure it probably looks fine for some things, but for this particular scene it just made my image look like it was shat out by stable diffusion. It was really bad - it muddied up the edges and made all of the small transmissive lights look splotchy and bad.
