I am currently using UE4 to create a stylized environment. I started this using the UDK and then UE4 came along and I recently decided to move this over and finish it. It is very exciting to see how you can use the UE4 for a stylized scene and find a nice balance between the art style and the tech. I am currently very carefully exploring PBR a bit to see if and how it can fit the stlye I am using. Here a a few screens of the current WIP.
Love the style. My only criticism would be that large horizontal gouge going through the large stones on the right. Doesn’t look very organic; small thing. Scene looks great all together!
