Weird shadows on my buildings

Hi, i need help with light and shadows settings, i’m having a weird problem with multiple assets i’ve done.
Pictures will explain for me :

No overlapping UV.

Thanks for your time
John

Each your mesh needs to have proper UV channel 1 for lightmapping. This link should clear it up for u.

You will also need to ramp up lightmap resolution. You might be using default 64 pixels for that large building. It should be way higher.

Thanks for ur answer i’m already making the lightmap uv before exporting instead of using the auto generated one

Anyway thanks Ill try to dig up more with your link.

Thanks alot FIXED with setting the lightmap resolution to 256px.

Please mark this as an answer, that way others with the same problem can more easily find it.

You’re welcome. Don’t forget to mark the question as resolved, kindly.
