I've a simple scene with two objects with the same material. Strangely, one of them is darker and I just can't figure it out why. No it's not their normals, I've already checked it.

Here's the scene: enter image description here

Normals: enter image description here

They don't have any textures. The worst is, if I export it into unity, the problem persists, so clearly something is wrong here, I just don't know what.

Any ideas?

Thanks!

  • $\begingroup$ It's hard to see many details of the lighting, so this may not be the answer, but one thing that can cause this phenomenon is if one copy is in the shadow of the other. $\endgroup$ – brasshat Nov 25 '16 at 14:58
  • $\begingroup$ It was an fbx file I converted to blender. My only guess is that something might went wrong, but I really don't know. $\endgroup$ – zbm Nov 25 '16 at 15:04

    $\begingroup$ Those are custom split normals, so either remove them or uncheck AutoSmooth, related - blender.stackexchange.com/questions/57036/object-renders-black $\endgroup$ – Mr Zak Nov 25 '16 at 15:26
