Quick start

• New facade: click Add Facade Plane.
• Your own building: select it, keep Surface = Plain Wall (or Modelled Glass for glass curtain walls) and click Apply Parallax Rooms. Roofs and floors keep their own material.
• Windows: change Across / Floors, or switch to Room Size (m) and scale the object – windows are added automatically.
• Presets + Randomize Rooms for instant variations.

Panels

• Colors – facade and window frame colour.
• Lighting – Lights On Chance, Light Strength, Ambient, Colored Light Chance, Ceiling Lamp Glow, Pendant Lamp Chance.
• Furniture – furniture amount, TV/PC screens.
• Curtains & Blinds – chance, amount and colours (fixed or random).
• Image Atlas / Custom Atlas – photo back walls, or load your own 4×4 image.
• Day & Night – Daylight slider for the whole city.
• Ceiling – ceiling variety and colour.
• Glass – reflection, roughness, tint, darkening.

Tips

• Animate Lights On Chance from 0 to 0.6 to make the city wake up.
• Use a different Seed per building so neighbours never repeat.
• Works in EEVEE and Cycles; rooms are a shader effect made for exterior shots.
