All sections have an opacity map. This makes the room very, very versatile. The floor is a reflective floor to reflect the walls of the room. This mesh you only see one level. Do not change the black texture.

Partitions in the middle of the room can be removed by adding a black 1x1 texture & 'opacity' (unclick the Blending box) to the 'Diffused color'. Mix and match the middle partitions or remove all of them all together. The room is very versatile.

Make your walls ( 1, 2 or a few walls) a solid color by adding a white 256x256 'opacity' texture, same for the stairway pedestal. However, to leave the floor as a reflective floor, leave the opacity [21] as it is. Circular stairs and balcony on either side of the mesh. All textures are 256x256.

Animate the partitions by: 1. click to the wall you want to animate. 2. go down to -texture animation- in the PREVIEWER. 3. Make the mode as "scrolling", frame/cell = 1 direction x = -1 (OR -1 depending on which direction you want) ... or direction y = 1. 4. in the box On the far right, put a tick in it.
