Rotating Skybox not working

So I’m trying to make a space level and want the space skybox to rotate to feel like your space station is rotating. I followed a tutorial and pretty much nailed it, but it doesn’t seem to be working. I was using THIS tutorial by the way.
All it did was cause my skybox to have a slight jitter to it. However when I go into wireframe mode it shows the skybox spinning correctly. Any ideas?

I also have a video of it. What am I doing wrong? - UDK4 Skybox Rotation - YouTube

Don’t suppose your sky material is worldSpaceAligned?
