For my group, I did the final layout as part of the level design, applying materials in Unreal onto the in-game assets for the level. The main centrepiece of the church, not made by me, was a difficult process, as I had to remodel the hill it was placed on so that the ground didn't clip through the floor. It was tough, but I learned a lot about level/ game design because of it, even though I was just an artist for the project.
