Can UV maps have a wrong and right side?
I've modelled a suitcase in blender and unwrapped / smart projected the faces for a uv map fine. But I have a big issue when applying my material with a normal map. On the top surface of the suitcase the normal mapping is really weak, but once the suitcase is opened you can see the normal mapping working decently. What have I not done correctly to have such weak normal mapping on the top of the object? Attached are example pics. The first of the top of the suitcase and the second of inside.
Thanks in advance for your help.
$$anonymous$$aybe the uv mapping for the top surface isn't as stretched out as the one for the inner surface. That way, the normal map naturally is smaller and you have less pixels that can receive light.
