I can't believe this situation...Do you guys forget that making a game is VERY different than creating an scene with Unreal 4? Do you forget that Nokon Kid is onboard? Nokon was able to recreate almost all places from Shenmue 1 all alone, with passport's model of Ryo.
The graphics part is thelast one, they first create the rutines, I.A of NPCs, collisions, mocaps...a lot of HARD WORK before polishing graphics. In most works I've seen made in U4 by amateurs they don't have to control enemies, NPCs, game routines...only show a beautiful scene, but just this, a scene.
It's imposible they have problems with creating graphics when Nokon Kid alone could do it.
You have to be more patience, I'm sure next year we'll all be amazed with the improve they'll do.
