So I downloaded a skybox that has the ring world from Halo in the sky. I followed the skybox tutorial and made sure the texture was set to clamp to remove the seams. But then there is this: http://imgur.com/yIrGGY9
So I asked a friend if he can make me one and he did. It matches colors and everything but again this:
Can you post the tutorial?
What kind of material is it? A special skybox material? (which if it exists, I have no experience with) Or a diffuse? Perhaps try making the material an unlit texture?
