A lineup of procedural cyberpunk towers, mid-rises and shophouses in hazy daylight

Cyberpunk cities
in a single modifier

Cyber City Generator builds detailed neon skyscrapers live from one Geometry Nodes modifier, then grows them into entire cities with streets, shops and signage.

6Building families

16Shop types

13Animated ad loops

4+City layouts

Features

One modifier, one tower. Add the BT Tower Generator modifier to any mesh and a complete tower builds itself live: mass, setbacks and crown, facade bays, technical floors and roof plant. Every input is a regular modifier field, so you can drag it, keyframe it or drive it.

A tower being generated step by step while the modifier values change

Endless variations. Separate seeds for the mass, facade, ads and lights. Keep a silhouette you like and re-roll only its lights.

Six building families. Belt, Terrace, Notched, Blocks, Tech and Shophouse each have their own silhouette and facade system.

Day and night. Under a hazy afternoon sun the neon keeps burning. After dark the rooms light up floor by floor, with fake interior depth and curtains.

A divider sweeps across the same tower from night to day

Real materials. CC0 PBR sets are box-projected in metres. Each panel has its own tone, and grime streaks down from every joint.

Screens and neon, never text. LED screens play 13 animated pictogram ads, and signs use pictograms only. There is no lettering and there are no real brands.

Hero tower with screens and drones at night

Whole cities, one command. The city builder places hundreds of towers on a street grid. Choose a layout (grid, downtown, strip or megablock) or set your own blocks, block size and street width.

City layout plan, then the rendered aerial

Street-level life. The builder adds 16 shop types, neon totems, sign gantries with pictogram direction signs, traffic lights, cables and bollards.

A kit to start from. Towers, mid-rises and shophouses: 30 buildings ready to place by hand.

Built for big scenes. Small parts drop beyond a distance from your camera, so a full-city aerial at 1080p fits in an 8 GB GPU. Every building stays a live modifier.
