Using a movie texture would be a big waste of resources for something so simple; looks like you could just use a static texture and rotate it.

Movie Texture is what you need:

maybe you can use the Material.mainTextureOffset, which can animate something like water.and there is demo as you install Unity. here is the offical document link text
