Lighting artifact problem

Hi, I’m getting some weird artifacts on my meshes after building light(regardless of quality) and I’m not sure where to start with this. I skimmed through the Lighting Troubleshooting Guide on the wiki and it seems like it might be a UV issue, but I haven’t had luck fixing it so I came here hoping someone can point me in the right direction.



There’s a couple of things you can try–first, you can increase the lightmap resolution, you can see that’s the shadows being pretty low resolution to how blobby they look due to the texture filtering. That’s because the resolution is low and then pixels are big. You can also try to make sure that the edges of the meshes aren’t intersecting the wall or whatever it is, parts that are intersecting would receive shadow and since the lightmap resolution is low that will cause the shadow to bleed onto the outside to where you can see it.

I increased the lightmap resolution up to 512 and that seemed to get rid of it. Thank you very much!
