The VRScansZone is used with specific vrscan materials which consist of two or more clearly defined sub-materials (e.g. some fabrics with pattern). It renders a mask for the zone which is shaded with the respective sub-material. The result mask is monochrome with white area corresponding to the distribution of the specified sub-material and black color fill for all the other parts of the image.
The VRScansZone render element only works with the scanned materials which have the respective zones channels defined inside them.
This render element is enabled through the Render Elements tab of the Render Setup window in 3ds Max and displays its parameters in a rollout at the bottom of the window:
