V-Ray Distance Texture

Hey everyone!

I was trying to recreate this amazing tutorial by Bernand Benoit (NAKAGIN PHOTOREAL ROAD TUTORIAL) and was wondering if there was something I can do in Rhino to replicate the Vray Distance Texture he uses to create the lighter areas in roads near the curbs. In Max apparently the Vray Distance Texture uses a geometry to indicate in which way the distance map should be applied.

I considered using a Falloff map, but it only lets me specify a vector in the Distance Blend type.

Is there another way?

Thanks

Also, in the same tutorial he uses a composite material, and get vaious blending modes (similar to photoshop layers). Is this a 3dsMax thing?
