Simulate Concrete board facade

[kenoeightspot]

Left image has the exterior material set to 1/2" "Concrete and blended with another color.
Right image has exterior material set to 1/2" concrete and then painted with "American Clay"
The joints are made using the "Wall material region" set to cut parent layers, set depth to 1/2" less than your exterior layers so the revel does not cut further back than the cement board thickness, then I used a dark
color to show a shadow effect. Space your reveal ht. as desired, copy and place more reveals using multiple copy if the spacing is uniform.
