Maya Arnold procedural dirt from ground

David_McCabe

Hi,

so i have a car model that is made of many objects and is procedurally textured. what i want to do is add a dirt layer coming from the bottom up as in the real world across all the various objects that make up the model. Any help on the best approach to this would be greatly appreciated.

Many Thanks

David

If you need to keep this procedural, use a projected ramp to create the vertical gradient and mix that with some noise. If you plan on animating the car in maya, be sure to keep the projection node in the same space/group as the car- don't want the dirt changing if the car goes up a hill.
