A dense city block seen from above — skyscrapers, setbacks, rooftop clutter of HVAC units and antennas — rendered as untextured clay so the scale, massing and geometry carry the frame on their own.
A downtown seen from above, rendered in greyscale clay. Stripping colour and texture puts all the weight on geometry — the massing of towers, the rhythm of setbacks, the clutter of rooftop mechanicals — to see whether the scene holds on scale alone.
The density is the point: enough buildings, each with believable rooftop detail, that placing them by hand isn't the move. It's an environment/scale exercise in the same procedural vein as the generators.
