Quick start: one tower

1. Unzip the download and keep the folder structure. The .blend files find their textures through relative paths.
2. Open CyberCityGenerator.blend, select Cyber Tower and open Properties > Modifiers > TowerGenerator.
3. Change the inputs. The tower rebuilds live.

To add a tower to any scene, add a mesh and choose Add Modifier > Cyber City > BT Tower Generator. The tower grows from the object's origin.

To use the modifier in other files, add the folder as an asset library (Preferences > File Paths > Asset Libraries) or append the node group BT Tower Generator.

When Blender asks about Python scripts, click Allow Execution to get the Night Towers sidebar tab. It has day/night preview, presets and the ad image loader. The generator itself works without it.

Inputs

• Building:
  • Family: 1 Belt, 2 Terrace, 3 Notched, 4 Blocks, 5 Tech, 6 Shophouse, or 0 to pick one from the seed.
  • Seed, Floors, Width, Depth, Setback, Asymmetry.
• Facade: Facade Seed (re-rolls zoning, materials and modules only), Floor Height, Bay Width, Tech Detail and Weathering.
• Ads and Signs:
  • Ad Seed: re-rolls screen images and sign pictograms only.
  • Ads and Signs: densities.
  • Screens: on or off.
• Lights: Light Seed (re-rolls lit rooms and neon colours only), Lit Windows and Neon.
• Animation: Animate, Speed, Elevators, Drones, Sky Traffic, Ad Tower and Crown Ticker.
• Content:
  • Ads Portrait and Ads Landscape: your own screen images.
  • HVAC, Service and Antenna kits: your own roof parts.
  • Leave them empty to use the built-in kit.
• Performance: LOD Camera and LOD Distance (small parts drop beyond this distance), and Realize Instances.

Building a city

Open CyberCity_Demo.blend for a ready-made city. To build a new one, run this in a terminal in the product folder:

blender -b --python build_city.py -- --layout grid --save MyCity.blend

• Layouts:
  • grid: 9 x 7 blocks
  • downtown: 6 x 6 big blocks
  • strip: 13 x 3 boulevard
  • megablock: 5 x 4 huge blocks
• Custom grid: --nx --ny --bx --by --street. Add --seed for a different city.
• A city builds in about a minute. Every building stays a live modifier.

Rendering tips

• Night: Cycles, 32 to 128 samples with the denoiser, AgX Medium High Contrast. Bloom comes from the compositor.
• Full-city aerials: set LOD Distance to about 400 m and LOD Camera on the towers. The scene then fits in 8 GB of GPU memory.
• Your own ads: use 9:16 images for portrait screens and 16:9 or 3:2 for landscape screens.
