First of all. Great work!! I have the knowledge since the start and i, just like many others, could see an amazing advance in it. Congratz!!
Well i still think that the ring should be one part and the rotation would be an animation. I played a lot with IR and i've created a sort of rotating ring too to my ships. The thing is, when i try to make maneuvers i need to stop its rotation so i can be able to perform the maneuvers accuretaly and i need to stop its rotation to time warp because if i don't all the thing explodes. Well that's my opinion but you who decide things here, i just wanted to leave the reasons of the why of my thinking. Continue the work, it's great!!!
