Thanks for your perspective. It's always good to see the perspective of someone on the "other side of the fence". You are right when you talk about Unreal rendering and two-sided materials. It's expensive. In regards to copyright claiming, to me, it feels too close to censorship and something I think we'd only do in extreme circumstances.
The bigger question I have (and it's a genuine one) is why do you mesh? I've heard the "I mesh because I have to prevent meshers", but at some point, that cant be the case. Maybe it's the thrill of finding the exploit or breaking the game? I've always been curious as someone who has played ARK considerably. Undermeshing wasn't a huge thing back when I was playing.
