Hey guys!
I have these weird light patches at my level. They increase its number every time I build the lighting again,(it’s on production).
Any ideas how to get rid of them?
Cheers,
Alex
Are you using static lighting from emissive textures? It could also be an issue with lightmap UV’s
No.
//It’s weird. Because mostly on this place, also appearing on other building with different textures.
Any ideas how to fix/reset the lighting?
If the buildings are a single object then the lightmap might not be big enough. But it also looks kind of similar to a very low sample lighting render which shouldn’t be happening at Production preset
Yeah, at these places there’s no active light of any kind.
Any suggestions how to fix?
Can you share a screenshot of the lightmap UV’s for one of those meshes?
Yeah sure,
UV channels 2 looks good tho
Your mesh is too big to be a single object, even with a very high resolution lightmap it can have issues. Also, it would be better to do the UV mapping yourself, rather than using an automatic method because the automatic methods usually split up the mesh too much. Also make sure your lightmap is not the default 64 pixels which is too low. And make sure your lightmap UV channel is set correctly–that would be the Lightmap Coordinate Index in the static mesh window.
Thanks for the reply!
I just find 2 things weird.
#1 There’s no light at these areas at all.
#2 The amount of these patches increases with every single build.
I can’t make UV maps right now by myself, they’re marketplace assets.
Is there a chance I can reset all light like before? Was thinking the engine doing it itself.
The issue is that if the UV’s are bad then any light would cause issues on other areas of the UV’s
It’s odd that marketplace assets would have bad lightmap UV’s, if the maker has a marketplace thread I would post that in there, they’re both using automatic mapping and have bad results.
You can reset the lighting but you have to build the lighting so it will return the way it was when you rebuild it. The only way to avoid the issue is to not use baked lighting and instead make your lighting fully dynamic which won’t give as good of lighting. Though it can be necessary to have it be dynamic if your map is really big or if you need a day/night transition.
Thanks! Would take some actions
