parallax rooms in Blender

On a related topic, and many may already be aware of this, but there is this (complex) system of nodes in Blender that can generate 3 dimensional rooms from a single flat plane ! If only this would work in sketchup!

This another explanation

Yes, this kind of parallax rooms is what inspired RoomBox! However, because SketchUp doesn’t support shaders, we could not do it with a single plane. So instead, we generate a bit of geometry (a box, with a few planes) but it’s still very lightweight.

The map format is the same though, so maps used in Blender with this approach should be compatible with RoomBox in SketchUp.
