Getting started

1. Open Eastern_European_Panel_Building_Generator_v1.blend in Blender.
2. In the Outliner, expand GENERATED_BUILDINGS. It contains Example_01 through Example_12.
3. Select an Example object, then open Properties > Modifiers to find the Geometry Nodes controls.
4. For a manually designed building, disable Random Building. Set Floors, Entrances, Width Blocks, Window Bays Per Entrance and Floor Height.
5. Refine the facade, roof and lighting with the remaining modifier controls. To explore overall layouts, enable Random Building and change Building Seed.
6. Duplicate an Example object for another building. Adjust that object's modifier settings for a different result.
7. To use the generator in another Blender project, use File > Append to bring in an Example object from the product file. Check the imported materials and modifier in the destination scene.

Control groups

• Form: floors, entrances, section width, window bays, balcony columns, floor height, ground-level entrance, technical floors, section offsets and entrance projection.
• Facade: front and rear balcony patterns and probabilities, blank columns, end-wall color patches, decorative grilles and side windows.
• Details: house numbers, stairwell grilles or windows, air conditioners, satellite dishes and roof antennas.
• Variation: Random Building and Building Seed control overall layout; Variation Seed changes smaller details.
• Lighting: Window Lights, Lit Windows Amount, Window Lights Seed and Light Brightness.
•  Roof and color: roof access, door side, ventilation, ladders, grille color and mosaic color.

For normal use, change the modifier controls on an Example object. Save a copy before editing source modules or the Geometry Nodes setup. Turn off Random Building when you want the manual form controls to take effect. Use Window Lights Seed to change light placement without changing the building layout.
