Okay, this is an easy one. There are a few things you need to do to make a sky zone rotate. Take a look at the pic below:

Notice that the only values set to True are: bAlwaysRelevant, bHidden, bMovable, and bNoDelete. Everything else is set to False. It is very important the the option bStatic is set to False. If it were set to true then the sky would stay stationary.

Now that the Advanced properties are set up the only other thing we have to change are the Movement properties.

Make sure bFixedRotation is set to True . Next, click the drop down arrow next to Physics and change it to PHYS_Rotating. The last setting to tweak here is under RotationRate. Change the Pitch, Yaw, and Roll to your desired results. The settings above are from the map CTF-Face. You may want to use different settings in your level.

Remember that the skyzoneinfo icon acts like a camera.

All the decoration that is placed around the icon will now appear to rotate in the game. The placement of the skyzone info in relation to to decorations will alter the way the skyzone looks. Play around with the positioning until you get the look you are looking for. Below is an example:

That concludes this tutorial. The rest is up to your imagination. The only way to truly learn the depths of sky zones is to try different things. Experiment!
