Problems with baked GI lightmaps.

[Entaryn]

Hello,
I have a problem with generated lightmaps. I use URP. I want to have baked GI on static objects and realtime directional light. When I bake the GI, I get this wierd result. I assume its a lightmap problem. I’ve made some research and saw simillar problems but nothing solved my problem 100%. Here you can see some screenshots of some settings that might be helpful. I haven’t made lightmaps manually in blender in this example (thats why I have Generate Lightmap UVs checked) but I have tried it and got simillar results (maybe I just dont know how to do it in blender). I feel like the baked lightmap image is wierd in terms of resolution - its so blocky, but some parts are higher res.

EDIT: I forgot to open the Generate lightmap uv settings in the screenshot. They are 88, 8, 15, calculate, 4, 1

import settings:

Scene lighting settings:

Baked lightmaps:

Direction light settings:

Project Graphics settings:

Thank you,
Patrik P.

Hi Patrik,

To help us narrow this down, could you answer a couple of questions? When generating the UVs, did you change the default settings in the ‘Lightmap UV settings’ dropdown? Also, do you still get the same artefacts if you switch off filtering or run with the CPU lightmapper?
