oh the feeling when you finally understand something that’s been bothering you for a while! I’ve been struggling with ugly shadows, light bleeds and splotches for two weeks now. searching for answers around the web gave me only bits and peaces of needed answers. finally a simple sentence that I stumbled upon made everything click into place: “too high indirect lighting values can introduce artifacts in shadows”. so simple, yet it took me ages to find solution to my problems, as that was nowhere said explicitly. I’ve gone back and forth with lightmaps, lightmap UVs, UV pixel snapping, padding, this’ and thats, yet this simple bit of information solved it all. now I leave indirect lighting at 1, and raise camera sensitivity in postproces volume.
here are some screenshots from a test scene. don’t mind the weird materials, these are just placeholders. I know, I know, you’re all probably going like “listen to this guy, haha” but I’m so relieved that I can move on in learning process. :-))))))
