The work on the variations is progressing faster than expected, since I discovered the "merge" tool which allows to... merge (amazing !

) parts of different tiles. There's still a lot of work to do though, essentially move and rename some geometry parts, and test the tiles to see if nothing is missing, and to be sure the walkmesh baking is ok.
I have now several variations, which give some diversity in my dungeon. Let's take for example the "1_wall" tile, which has now 8 variations (sorry for the quality of the pics, it's been taken in the toolset) :
-
base tile (no, the dwarf is not a part of the tile

)
-
drain-
large pit-
alcove (with a placeable corpse I made)
-
missing slabs (with an other corpse placeable I made from a stock skeleton)
-
roots piercing the wall (I used a stock cave roots placeable to build this)
-
circular pit-
circular pit with a grate (walkable)
I also plan to make some other placeables to decorate and add some happiness to this gloomy place. Like rusted chains hanging on the walls and from the ceiling, for example:lol:
