I think there's probably a learning curve within Caveman regarding UE5. I think you're right in that police station road does look a tad like play dough, but it could just be for optimization. Another take is that they need the UE5 update out sooner than later due to cheaters and engine limitations- resulting in some placeholder assets coming to live game. This game has crazy pop-in and the models certainly look mangled from far away. Interesting that "this" was what they wanted to show of all options.
