Here's the tiles I did for Dumb 'n' Dinner, the game I've worked on this year for my teamwork classes with my Concept Art academy. I've realized some seamless tiles and I've applied them to the UV map of the dungeon walls ( I only did the walls one, not the floor ones ) cooperating with the 3d artists of my team. Then I also transformed the UV map in a Displacement Map in order to give more depth to the dungeon. I also made some mockups with my team-mates to have a look at the tiles applied to the map and also to study the general mood and colors of the game.
