I made an elevator that wasn't jumpy in DM. Only....my elevator didn't work exactly like an elevator. I had it resting at the top of the shaft, and when the button was pressed it fell really fast to the bottom, crushing anyone in the shaft. Then it slowly rose back to the top and reset itself. But you could get in it too. I just made it a tracktrain (i think)... I never actually released that map....it was more of a neat idea than a good DM map. I went a little nuts with the brushes...learned my lesson :| .
