Blender Geometry Nodes: Building a Parametric Architectural Generator
Harness the power of Blender Geometry Nodes to create a dynamic building generator. Control story counts, wall panel variations, and window distribution procedurally.
Procedural modeling allows architects and 3D artists to generate complex urban environments without manually extruding individual faces. Blender's Geometry Nodes framework offers flexible non-destructive workflows for architectural asset generation.
1. Grid Resampling & Curves to Instance Setup
Start by converting base footprint curves into resampled point networks using the Resample Curve node. Distribute instanced structural columns along corner vertices and feed edge vectors into an Instance on Points node to distribute repeatable wall modules automatically.
2. Procedural Floor Instancing & Height Controls
Utilize integer math nodes to repeat building stories along the global Z-axis. By exposing floor height and total level parameters to the modifier stack, you can scale structures dynamically while automatically capping top floors with custom roof ledge modules.
3. Assigning Dynamic Materials and UV Mapping
Procedural instancing often breaks standard UV unwrapping. Inject Store Named Attribute nodes within your geometry tree to output vector coordinates directly into Cycles/EEVEE procedural material shaders for seamless brick and concrete tiling.
