Ejemplo

In this example, we wanted to take the rather boring array of ball bearings and add some variation to it. So, we dilated the red and eroded the green, leaving the blue alone. If we had dilated both red and green… (hint: red and green make yellow). The amount of influence is increased by increasing the Distance values. Blend-file available here.
