This is a shot from a larger sequence that I don't have time to finish up at the moment. The Truck is animated procedurally along a curve using a rig based on this one by Carlo Carfora https://vimeo.com/150671384 . The model itself was created by Prateek Aggarwal. The dust volume is just a rasterized pop sim which kept the scene fairly light. Render times were about a minute per frame on average, with the volumetrics topping out at around 2 minutes for the heaviest frames.
