The fact that the sets could be redressed in such a way was one motive for pursuing the idea . Remembering Manny Coto ' s response to the plan , Sussman relayed , " " He said , ' Great , because we can paint our Vulcan sets white and now it ' s ice ! ' and that ' s what we did .

" " And because we played that set over various episodes , we were able to amortize the building of the set and get bigger production value .
