Matching thunder and lightning? That's going to take some tricky.

I think the a40 grav lift only works in the cut scene. Elevators are easy, but not in multiplayer. If I remember correctly, it's a .JMO. You just save the elevator in the up and down position and create a switch to trigger each position... I'm fairly sure there's a tutorial on this site somewhere specifically for elevators, but it's by like a 15 year old kid.

could you make it a special effect? like the forerunner beam buildings? if you are close enough, you hear the sound. You just change the sound to a thunder rolling, make it louder, and make the beam be a flash of light behind the clouds or the actual arc of lightning underneath.

I don't do mapping yet, so i'm not sure how this would work with what the tools can do
