I agree if they made it more fluid so it can go inside small areas, every time I start up my little cooking kit, the fire goes out in the grill because of the smoke.
Rconover just make it less dense, real smoke isn't dense why does this have to be?
also, why not a version (or maybe a viewing mode?) without any particle effects at all? I (and I know for a fact that I'm not the only one) personally don't like any of them.
lolzy I have asked for customization of walls before (with drop down menus to decide what properties it has) but I think someone said that it was way too hard to make GUIs in SDL. I don't know if this is true or not, but I support the idea.
