The problem with that is an overly complex walkmesh that would crash NWN. I tried it.
@ Miss Jaded:You should be able to get 359 degrees around the stairs (just short of a single revolution).
The problem comes in the engine not allowing walkmesh above walkmesh.
Think of walkmesh as being an image of graph-paper being projected from above down on the geometry of the tile. Only one place vertically on the stairs could have walkmesh. So you can have the PC walk around in a rising spiral, but the spiral would have to end before it wrapped around above itself.
Does that make any sense?
