Dirt simulation in Houdini or FumeFx

I have two 3ds Max+V-ray scenes. You can see renders in attachment in the bottom link. Inconspicuous, gray town (stage 1). People with sad faces and drooping heads (animation of people - not your problem). In the center appears a colorful house. Stone, wood, all kinds of paint. All citizens freeze in place. Turning towards this house. Top view (the scene is drawn on also). From these building to the edges rising construction dust. City drowning in its cloud. Dust falls. City full of colors (scene 2). Different textures. Satisfied people netoropyas stroll through the streets. The view from the top. Colorful houses make up the company's name. Your task - only in the simulation of dust. Perhaps it will be necessary to add emerging from the ground through the dust scaffolding. The scene was done in V-Ray. If you are working with Houdini, dust can be rendered in a channel with alpha. It's no problem. If you can do this effect in the max, means FumeFx or PhoenixFD or something else, you are welcome too. From you necessarily price and portfolio. Link to the storyboard and animatic rough (video only 15 seconds. Dust, 3-6 seconds) and sketches [login to view URL] P.S. It is desirable that used in the dust beautifully refracted sun. And no any noise, because this is video.
