Brick

The brick shader has multiple outputs that can be used to drive materials as seen in the example shader graph with the following key details:

• The Dirt Mask output is being used to drive the reflection roughness of a material even though the dirt layer is not visible in the Color output itself, all of the dirt parameters are still being fully utilized to determine the dirt mask.

• A color layer node is being used to change the surface color of the material by using the dirt mask and gaps mask to control where the additional blue and green coloring should be visible.

• The Displacement Color output is being used to give the bricks in the scene actual 3D depth at render time.
