This is a 3D interpretation of the starting tile for the board game Dungeons & Dragons: Castle Ravenloft, a dungeon crawler game where the hero party enters a castle inhabited by a vampire called Count Strahd von Zarovich. I made the asset with Tabletop Simulator as a target game engine in mind. You can find nice renders on my ArtStation here.
The “skulls” are an indicator for the game where monsters can spawn. I lazily used Suzanne from Blender for this, also it adds a nice easter egg. :)
