I made a staircase.
The geometry (CSG) and lighting (Multicolor Lightmaps) where made with the 'Runtime World Editor' (Download it, its awesome!), the textures are from Portal 2 (I love this Game), and the Game-Engine that renders the whole thing is one of my personal projects.
There is also physics and a First-Person Camera system ('KinematicRigidCamera'), that can be swapped out with a 'FreeCam', or the default JBullet camera ('KinematicCharacterController'). Next on the ToDo-list is to refactor the code to allow multiple kinds of 'Entities' like levers, buttons, doors, boxes you can pickup and carry/throw around, NPC's and Dynamic-Lights. Then I could actually make a small interactive World.
A 3D-Labyrinth, maybe?

Is that ssao or lighmap with textures that already contain baked occlusion?
