Stands out in the superhive library for generating circuit boards entirely through Blender's Geometry Nodes, keeping every parameter editable.
Procedural Pcb Generator uses Blender's Geometry Nodes to build 3D circuit boards with real depth, customizable trace paths, and dynamic component distribution. It's aimed at sci-fi environments, hardware visualization, and tech-art projects.
Traces are fully procedural, letting you control the density and routing of copper paths without destructive modeling. Component distribution automatically populates resistors, capacitors, and IC chips based on customizable seed values. Solder mask and silk screen controls change colors and wear levels, and the workflow stays non-destructive, so parameters from board dimensions to trace thickness remain adjustable. The setup is built to handle complex visual detail without hurting viewport performance.
Optimized for Blender 3.6.x (LTS) and compatible with 4.0 and later, it works with both Cycles and Eevee, with Cycles recommended for realistic refractive solder masks. The download is a .blend file that includes the Geometry Node setup, a master node group, pre-configured procedural materials, and low-poly component assets for instancing, along with a documentation and quick-start guide. It's distributed under the GPL license.
Procedural Pcb Generator is best for sci-fi environments, hardware visualization, and tech-art projects that need detailed 3D circuit boards.
Procedural Pcb Generator is completely free to download and use.
Procedural Pcb Generator is optimized for Blender 3.6.x (LTS) and compatible with 4.0 and later. It's built on Blender's Geometry Nodes, and the developer lists that supported version range. If you run a version within that range, you can generate the circuit boards and adjust their parameters non-destructively at any time, from board dimensions to trace thickness. For the exact supported range and any updates, check the developer's page before installing.
Procedural Pcb Generator works with both Cycles and Eevee, and the developer recommends Cycles for realistic refractive solder masks. The package ships with pre-configured procedural materials, and its solder mask and silk screen control lets you change colors and wear levels to match your project. Because the workflow is non-destructive, you can adjust these parameters at any time without rebuilding the board from scratch.
Procedural Pcb Generator comes as a .blend file containing the Geometry Node setup. Inside you'll find one master Geometry Node group, pre-configured procedural materials, and a set of low-poly electronic component assets for instancing. A documentation and quick-start guide is also included. The component assets are basic electronic parts, and the tool's dynamic distribution populates the board with resistors, capacitors, and IC chips based on customizable seed values.
Procedural Pcb Generator is listed as free here and distributed under the GPL license. Licensing terms can change, so check the developer's page for the current details before you download. The GPL license covers how you can use and redistribute the .blend file, node group, materials, and component assets included in the package. If you have questions about usage rights, the developer's page is the best place to confirm.
