Metal - "Cascade"

For convenience, Pivot models are configured so that, with reference to Vertex, they are placed on the roof frame.

A metal sheet has a substrate, in edit poly it is enough to hide the roof geometry, leaving only the substrate (Plane), and lay out the sheets as Instance along the perimeter of the roof, if necessary, apply the slice modifier to the group of selected elements, then make Unhide All in edit poly.

The choice of color is made through CoronaMultiMap, also present in separate slots.
