Cheap smokes Created 12 years ago2012-02-15 14:38:13 UTC by Captain Terror

I'm trying to fill a glass room up with smoke. What is the best way to do this for the performance-wise?

How big is that room?

Fog machine?

small, like 12x14" 10" in height.

Rim: chea mang but ima outta fog fluid sir ='(

Probably a transparent solid with some sort of animated smoke sprite inside it will do it.

isn't there a fog_volume or something for source?

func_dustcloud or func_dustpuff?

Or use fog_volume if it's a l4d/2 map and make it use a fog_controller that has a very close range...of course this will only appear when you enter the room itself unless you have several fog controllers and volumes set up.

Thanks rabid i will try the dust entities for sure and see how they work. Are they cheap to render?

I could do it the way Bruce said if i could only find the proper animated sprite..

They are rather expensive to render like all particles which use a lot of screen-space, but if you don't have too many sprites emitting per second you're okay. That means some playing with the right scale/emission values to get something that looks ok without raping your fps
