Pixelstudio (Moving) skybox clouds not tiling correctly

I'm trying to create a moving sky box for my game but the clouds refuse to render correctly. I've tried adjusting tiling but it has no effect in game. Please help! This is what it looks like in game: http://i.imgur.com/4EZHzm7.png This is what it looks like in my game view (Play unclicked) http://i.imgur.com/EUMBLH7.png The second one isn't too bad but it's tiling is still off. I'm confused why it's rendering different when I hit play. I'm using unity 4.1.2f1
