This is a simulation that can be cast into any scene with minor editing to the domain and amount of particles. Not very taxing on any PC to give depth to any scenes that need a bit more lifelike realism to them. I did follow a tutorial so this will be a free product. Sorry I don't have a lot of images. How else do you want me to show dust without puting random stuff in there that people will think they are getting. What you see is what you get.
