3D Dungeon Tileset
I made this tile set for OpenDungeons. The preview is just a mock-up render.
I needed to create a lot of connector tiles to close all gaps.
The photo sources of the textures are from Burningwell.org. The torches are not included and the barrels can be found here: http://opengameart.org/content/wood-barrels-pack
The tiles have a binary naming scheme (0 if the adjacent tile is empty, if the adjacent tile is filled).
Explained here: http://forum.freegamedev.net/viewtopic.php?f=45&t=3949&hilit=tileset+binary
There's also an .obj export script in the source file that will batch export all selected objects.
