This wall is mirrored so i'ts using the same uvs position for both sides, but for some reason in one side the trim normals are inverted. I have the same setup inside blender and the normals look fine there. Any tips on what i can try to fix this?
Some update, the problem seems to be happening because i have the trimsheet on the second UV channel, still no fix tho. I first thought that the normals were broken only on one side, but even the ''not broken'' side have some weird behavior with light.
Attached both walls and normals if you want to test it, check ''combine meshes'' when importing.
