I was modelling this jeep and noticed this weird shading when i was almost done. As you can see, its only on one side of the model. I tried applying the mirror mod, re-bake the lighting and even changed the angles of the light but its still there. I even placed my model in a clean blender file and its still there. Never experienced or seen this happen before. Would be nice if anyone could help
I could not see your image but sometimes when you mirror parts of an object the normals get mirrored as well. To fix this in edit mode select all the verts and go to the “mesh menu - Normals - recalculate outside” (Shift N).
