I’m guessing my issue related to my geometries, but I don’t exactly know how it can affect the lightmapping result.
The result must be like the first picture, but that’s when there is no lightmapping applied. When I baked the scene, I get the second picture.
there is only one directional light set to the Baked mode and no other light source except the default skybox.
Does anyone know where the issue might be from?
