Create dense futuristic residential and commercial architecture inspired by Unity's original 2018-2019 Megacity demo. Use for large-scale city blocks, towers, podiums, elevated infrastructure, façades, streets, plazas, service structures and dense urban environments.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Megacity Urban Architecture Style Target: Three.js 0.187.0, WebGPU renderer (`three/webgpu`) and TSL node materials (`three/tsl`); no WebGL fallback, no GLSL. ## Purpose Create dense futuristic residential and commercial environments inspired by the original Unity Megacity visual language shown at Unite LA 2018 and GDC 2019. This is a visual and architectural style skill, not a Unity DOTS implementation skill. The target city should feel enormous, dense, vertically layered, industrial, futuristic, highly serviced, modular, populated and believable at street level and skyline scale. ## Core Design Philosophy Treat the city as a gigantic engineered machine. Prefer: - dense building clusters - stacked functions - strong verticality - horizontal and vertical infrastructure - modular façades - repeated structural bays - service equipment - elevated walkways - transport integration - visible mechanical systems - signage and lighting - balconies and terraces - vents, ducts, cables and structural frames - varied building heights Avoid: - clean sci-fi toy buildings - isolated towers in empty space - excessive ornament - fantasy architecture - random greebles …

How to install
mdr add wolffe/three.js-skills/megacity@sha256:d9516b00d3354f22The line at the top of this page pins the label git:20261031.50d32a4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
