Hello,
so basically these are the same textures but one is kind of glowing or a bit brighter. The thing is that I just copy pasted so that they’re the same. I don’t know what’s the issue.
Rebuild your lighting! That usually fixes things I can’t explain in the worldspace 
Thanks that worked! But do I need to rebuild my lighting every time? Because now if I move it a little tiny bit it looses it’s normal texture immediately and starts to “glow”.
If you move an object then it will remove the baked lighting on it.
