    When baking the lights in my scene, some (but not all) of the torch assets have this horrible white seam as seen in the picture. Any ideas what might be causing this and how to fix it? I provided my lightmapping settings in the second picture. I am using URP.

    Make sure the mesh has proper lightmap UVs (second UV channel). You can auto generate this in the mesh import settings.

    After baking, if you select the mesh does the inspector have a note about overlapping UVs?
