I’m looking to get some feeback on the most efficient way to animate, say, a star moving in a clockwise direction with a little star inside of it moving in a counter-clockwise direction. My idea was to just do it in flash and import the movie file into Unity and call it from there, but I’m not sure if there is a better way in regards to filesize, RAM, etc…
You can make animation clips that can rotate any gameobject, it just has to rotate 0->360 and loop. Attach your Star model (or texture) to this. No scripting involved.
Yes, with the textured plane selected go to Window → Animation (I think it is) and then you can create a Rotation.x or whatever axis you want for 360 degrees over however many seconds.
Read the Animation info here:

Since they are two different images, would I be able to create a prefab of them as one after each was animated?
