I created this render based on a custom off-road Porsche 911 owned by Sam of SeenThroughGlass. The biggest challenge was how to add dust to the car and have a trail of dust behind. I used layered materials in Corona to add dust on top of the surface, as well as ambient occlusion masks to add extra dust to the smaller areas of the car. It was a quick and effective way to create the effect of dusty surfaces without manually painting dust into every area of the car. Though I could have simulated the dust trail, I chose instead to use a combo of Corona volume materials, TyFlow and distance textures to create a similar look that was easily adjustable without any need to simulate.
Software: 3DS Max / Corona
