Koboh is a huge part of the game. I was responsible for a few parts of the vista and skybox. Mostly a various near vista cliff rocks. As well as the vista environment of the crashlanding cinematics.
The end result is massive teamwork done by many talented artists. Here are some of the artists who are also involved in creating this environment:
Concept - Gabe Yeganyan
Skybox - Hanhee Lee
Lighting - Hansoo Im
Environment - Jeremy Minor
And many more...
