supreme kotor

Alas, you can't do elevators in Kotor. The invisible walkmesh can't move. It's something the game engine doesn't do. Though, you could 'fake' it. Not by moving elevator itself. But the whole model around it could move up and down.

But I never messed around much with animations. And it's one thing Kaurora still doesn't handle IIRC. Still you could build something very simple, just a few boxes; to see if the trick would work.
