Well I've been working on the animation for this years idea and I've already got most of it complete i just recently ran into some weird artifacts in my sky. I used a geosphere hemisphere for my sky, and when i use a nice sky blue material on it i get some nice results such as this.
But when i try to use a picture for my sky to make it look more realistic, i get some weird results such as this.
I have no clue whats causing this and i was wondering if anyone had any ideas how to fix this?? It would be greatly appreciated!
