Adaptation by Crisis Connect: reduced geometry, reoriented and rescaled,
raised into a collapsed mound, with an interior debris section; divided into opaque
rubble and a foreground cutaway, preserved the original photographic colour maps,
converted baked unlit materials to rough lit materials with vertex colour grading,
combined with purpose-modelled collapsed apartment floors, columns, facade remnants,
reinforcement, field workers, a resident, characters and phones.
The scanned context debris is trimmed at floor discontinuities.
This is an illustrative cutaway, not an actual disaster
reconstruction. The artist does not endorse Crisis Connect.

Concrete fracture colour adjusted to dusty grey. Additional dust/grime
variation is applied using baked vertex colours. All runtime maps are embedded.

WEB DELIVERY OPTIMIZATION

Geometry is Draco-compressed; colour maps are re-encoded as WebP at their
original resolution. Normal and AO/roughness maps keep their original bytes.
Unused UV sets and pre-existing zero-area triangles are removed.
