This is an essential dungeon tile as you all know; it brings it to a whole new level! Forgive the pun. Now, for the stairs to work in my game, I'm using Step Offset in unity which tells the player if they can step over a certain height/ledge. Others might add an invisible slope for the physics, that's fine, just add a plane in blender, 2 high and 2 wide, with a 45 degree slope and put it over the stairs. I'm sure you can figure it out! Comes with normal and specular maps.
