What elevator instance do you need to use to get the elevator with the light shining through the broken panels. The 2 destructed Instances i have used does not have this effect.

You need a nice fog for this effect. The easiest way is to add the global_ents instance to your map. Call it global_ents

Then add a logic_auto give it onmapspawn; global_ents and press the down arrow to select an enviroment, most likely something destroyed. That will give you this nice effect.

Thanks lpfreaky90,that worked a treat.
