Wow... That's impressive.
I'm not sure if the overall time investment between producing good looking photos and complete renders (with your sail tutorial) would be comparable for me, since my knowledge level is novice in either case, but this is something I'd eventually like to spend time learning and experimenting with. I've always done instructions for every MOC I've built, whether initially done with actual LEGO and reverse engineered/ported to Studio later, or done in Studio from the beginning, and it has always bothered me how many of them are missing their sails, cloth flags, and (usually) strings.
In any rate, I stand corrected. I guess it's not impossible.
Thanks for doing that and providing a link to it.
