Using VRayDirt to create mask for edge torn

by Hammer Chen

A good geometry-sensitive mask is the key factor of making realistic material. Here we use VRayDirt plus a texture map to create a edge specific mask.

 1. VRayDirt

2. with "invert normal" checked. Swap default black and white color

3. Adding "Output" to enhance contrast

4. Texture map, through VRaytriplanerTex map

5. Mixing VRayDirt and texture map.

6. Final shading network
