This was a one day job since i wanted this to be over as fast as possible. Build the base Highpoly and quickly made the lp with cage in Max. Then baked and textured it. UE4 PBR metal shading is awesome. I quickly thew it intro Maya and made it spin. Since i wanted to put at least a bit of love and interests in the "animation" i decided to give the main base a little shiver so you, again like the other fan with the moving cloth, can feel the motion. 

Also ingame every base (starting rotation) is different so they dont look to similar. Even if you can´t tell it, you´d feel it!

I think its the small things that matter and makes for a great scene...
