Hey all, I'm trying to get some flowing steam coming out of some vents in my map. Looking through the dev pages it looked like Env_smokestack was my best option for the result. Most of the parameters are pretty self explanatory but I'm having difficulty with WindAngle. What should the integer look like? and x and y integer? also this doesn't seem to account for a downward direction, which is something else that I want to happen. Anyone have any experience with this thing, or is there another entity I should be using? Valve: I should note, that I used it before in another section of the map, as an actual smokestack and got it to look good enough, but my needs there weren't as specific.
