Height 1000

whenever i try and use the height 1000 command, my screen blacks out. is there any screen res requirements or anything to get it to work?

I believe it just happens to some people and not to others. My laptop is one of the best gaming laptops out there and it blacks out no matter on any settings. Same goes for my desktop.

What i believe this is:
In some maps, the final stage (where the boss spawns) still has a trigger to teleport you to the next stage (which is used for another boss). Usually you step through another trigger which deactivates the teleport-trigger, everything clear ? ^^
So what happens =>
You set your height => you touch the teleport trigger (which is still enabled), fade starts => Black screen !
