Erlik, Thanks for the link, "if you want the fog/mist to obscure the object," Not sure what you mean here - I've already got my mist to do as much obscuring as I want. Are you talking about starting to create a mist from scratch? If so, I didn't go that route, I just started with one of the preset fog/mists and tweaked it.
