Procedural Circuit Board Generator (Geometry Nodes)

Generate highly detailed, customizable PCBs for your 3D environments in seconds.

Overview

This procedural tool uses Blender’s Geometry Nodes to create 3D circuit boards with real depth, customizable trace paths, and dynamic component distribution. Perfect for sci-fi environments, hardware visualization, and tech-art projects.

Core Features

• Fully Procedural Traces: Control the density and routing of copper paths without destructive modeling.

• Dynamic Component Distribution: Automatically populate your board with resistors, capacitors, and IC chips based on customizable seed values.

• Solder Mask & Silk Screen Control: Easily change colors and wear levels to match your project's aesthetic.

• Non-Destructive Workflow: Adjust any parameter at any time from board dimensions to trace thickness.

• Lightweight & Optimized: Designed to handle complex visual detail without tanking your viewport performance.

Technical Specifications

• Blender Version: Optimized for 3.6.x (LTS) and compatible with 4.0+.

• Render Engines: Works seamlessly with Cycles (recommended for realistic refractive solder masks) and Eevee.

• File Includes: .blend file with the Geometry Node setup, a library of basic electronic components, and procedural materials.

What’s in the Box?

• 1x Master Geometry Node Group.

• Pre-configured Procedural Materials.

• A set of low-poly electronic component assets for instancing.

• Documentation/Quick-start guide.
