The woodgrain on the table and the sandstone on the walls are free PBR textures but the carvings and modeling I did by myself. I also did handpaint the entire board and the gamepieces and dice. On the board I also handpainted the roughness and generated the normals in Photoshop (which is not entirely necessary).
"Kevin" is not much of a challenger :D He's meant to practise with, but if you can beat Irving you're doing great! I'm glad you're enjoying the game.
Thanks for the donation BTW! I really appreciate it!
