I am leaning to use Unity for mostly basic VRChat worlds, nothing fancy, I just want some nice lighting for my Backrooms world. As you can see on the walls, a strange dark smearing has appeared, what would be causing this and how could I fix it? A lightmapping problem? This hasn’t happened on other projects, just this one.
Thanks.
Hi. Do you have Generate Lightmaping UVs enabled in your model import settings. Also, can you make a screenshot of your Lighting Window?.
Use Bakery (asset). Better than unity’s GPU lightmapper. If you’re not using HDRP, bakery is a good choice.
I bought and downloaded Bakery, works a charm! Thanks to both of you.
Yeah, unity’s auto-UVs and GPU lightmapper are a big disappointment. Bakery is a bit of a struggle in HDRP so it’s more problematic.
I will not contest the Bakery suggestion, but the first image looks to me like it “simply” doesn’t have enough (mostly indirect) samples and the denoising is failing to make sense of it.
I think the default values for samples of the GPU lightmapper are doing more harm than good, because they do not produce clean results in almost any situation and when I tell people they might need to go into tens or hundreds of thousands of samples, I get disbelieving replies like “that’s overkill” or something.
Spot on AcidArrow, this is the denoiser dreaming up strange artifacts because of too few indirect samples.
