I think this has been mentioned before, but I searched and can't find any answers.
I'm trying to make a decent looking glow for my fluorescent lights (I'm using the fluorescent light texture defined in lights.rad). The lighting works great, but when looking at the actual light...it just doesn't look bright enough, so I want to add a nice glow effect to them.
I tried using env_lightglow...but it fades out when you get close, and doesn't quite look right anyway.
I also tried using env_sprite, but all the sprites are round, and the light source is rectangular...which looks weird.
The last thing I thought of was using a rectangular brush about the size of my lights textured with a nice glow texture, tied to a func_brush entity with the render mode set to Glow or World Space Glow (not sure what the difference is, but the latter is used by Valve for most light glows). In Hammer it looks pretty good, but in-game it's rendered without any alpha...it draws the black parts of the texture along with the white part.
Is there any way to get the render mode to work properly with a bush entity, or is there some other way to make a good-looking rectangular glow?
