Okay, so I told a friend that I’d re-render an animation of his on my much faster computer, but when I render it the background doesn’t show up, instead the sky is just a solid, dark purple color. I tried just adding a giant sphere and adding the texture to that, but it still renders it as a purple sky. We had this working correctly just a few days ago, so I’m not sure what happened to break it, and I’m sick of banging my head against it. I uploaded the .blend and texture to:
I’d greatly appreciate it if anyone could take a look and tell me why it’s not working right. This is using cycles, and I’m on Blender 2.71.
