GBH Tool for Blender: the $10 hair add-on that automates your hair cards
Modeling hair in Blender usually means wrestling with particle systems, manual curve adjustments, or spending hours on card setups that break the moment you rig the character. If you are working on stylized characters, game assets, or animated pieces, the bottleneck is rarely art direction—it is the technical grind of generating, UV-mapping, and rigging hair geometry.
GBH Tool for Blender by Gixo is a $10 add-on designed to cut that friction. It sits on top of Blender’s native hair system, letting you generate hair strands, stylized meshes, or game-ready cards from curves or meshes in just a few clicks. It is a specific tool for a specific job: turning raw geometry into production-ready hair assets without rebuilding your node setup from scratch every time.
Quick answer
| Best for | Blender users creating stylized characters, game assets, or animated hair who need fast, repeatable hair card generation and automatic rigging. |
| Skip if | You need photorealistic hair simulation, work in Maya/3ds Max, or are on Blender 4.1 or older (requires 4.2.x+). |
| Price | $10 |
| Format | Zip file add-on (56.5 MB) installable via Blender |
| One-line take | A $10 workflow accelerator that handles the tedious parts of hair creation—UVs, rigging, and card conversion—so you can focus on the look. |

What you’re actually buying
At $10, GBH Tool for Blender is a low-risk entry into a specialized workflow. The add-on is a single zip file (56.5 MB) that installs directly into Blender 4.2.x or later. It is not a generic “hair pack” with static meshes; it is a procedural system that lets you generate hair from curves, meshes, or other curve objects, then convert that result into hair cards, meshes, or particle systems for further editing.
The real value is in the automation of the tedious steps. Instead of manually mapping UVs or painting weights, GBH Tool handles full UV map control (uniform or separated by length) and automatic weight painting for hair rigging. It also includes a library of pre-made node groups and sample materials, which means you can start with a working setup rather than building your own node tree from zero. If you are working on game assets, the tool generates hair cards specifically designed for that use case, complete with hair card texture creation features.
The add-on also supports vertex color-based hair distribution, allowing you to control where hair appears on a surface, and includes tools for creating braids, curls, and rolls without modeling each strand individually. You can load your own node groups and materials into the library, making it a flexible part of your existing setup rather than a closed system. For those who want to test the workflow first, a free version is available on GitHub for educational and testing purposes, though a purchase is required for any commercial or production use.
Beyond the core generation tools, GBH Tool is built to handle the messy reality of production assets. It supports mesh-to-hair conversion, a feature inspired by community workflows that lets you take existing mesh geometry and transform it into hair objects, expanding what you can use as a base beyond just curves. The tool also allows for conversion of hair into meshes, curves, or particle systems after generation, meaning you are not locked into one output format. If you need to hand off the hair to a different pipeline or continue sculpting it as a standard mesh, you can export the result and keep working. This flexibility is crucial for artists who need to integrate hair into broader scene setups rather than keeping it isolated in a specific modifier stack.
Why it’s on our radar
This add-on solves a specific pain point in the Blender workflow: the tedious, technical setup required to make hair assets production-ready. Instead of just offering a static hair pack, GBH Tool provides the procedural engine to generate, UV-map, and rig hair from scratch. For artists who need to ship stylized characters or game assets quickly, the inclusion of automatic weight painting and pre-built node groups saves hours of repetitive technical work that usually eats up project time.
What actually matters
Before you install, verify that your version of Blender is 4.2.x or later. The tool is built on the newer hair system, so it will not function in older versions.
Check if your workflow relies on curve-based modeling. GBH Tool is designed to take curves or meshes and convert them into hair strands or cards. If you primarily model hair using manual mesh sculpting without curves, this tool may not fit your current process.
Look at the rigging requirements. If you are creating static assets, you might only need the generation features. But if you are animating characters, the automatic weight painting feature is the key value driver—confirm that the automatic rigging meets the complexity of your character’s head geometry.
Finally, consider the license implications. The tool is released under GPL-2.0-or-later. Ensure this open-source license aligns with the proprietary nature of your commercial projects, as it may require you to share derived code if you modify the add-on itself.
Mid-check
If the workflow looks like a match for your current character projects, you can View on Gumroad to grab the latest v2.2.3 release.
FAQ
Does GBH Tool work with Blender 4.1? No, the add-on requires Blender 4.2.x or later. It is built on the updated hair system introduced in those versions.
Can I use GBH Tool for commercial game assets? Yes, a purchase is required for any commercial or production use. The free version on GitHub is strictly for educational and testing purposes.
Does it include ready-made hair materials? It includes a library of pre-made node groups and sample materials. You can also load your own custom node groups and materials into the tool’s library for reuse.
Is there a free trial version available? You can download a version from the GitHub repository to test the workflow. However, this is intended only for learning and testing; a valid purchase is required for professional work.
Bottom line
GBH Tool for Blender is a practical, low-cost solution for artists who need to streamline their hair creation pipeline. By handling the heavy lifting of UV mapping, rigging, and card generation, it turns a complex technical challenge into a manageable, repeatable process. If you are tired of rebuilding your hair setup from scratch for every new character, this $10 investment could save you significant time on your next project.
