A compact add-on with a small download size and no special permission requirements, released under the GPL v3.0 or later. Version 1.0.3 arrived in October 2025.
Spline Generator adds parametric spline creation to Blender through the Add Curve menu. It provides three spline categories to choose from — Simple, Fractal and Chaotic — and exposes its settings through slider-based options. As values change, the spline updates dynamically.
The add-on ships with a set of presets, including Lorenz Attractor, Rossler Attractor, Dadras Attractor, Halvorsen Attractor, Torus and Rhodonea. These give starting points across the different spline types available in the tool.
Spline Generator is compatible with Blender 4.2 LTS and newer, and is distributed under the GNU General Public License v3.0 or later. It requires no special permissions and has a small footprint. It can be added by dragging and dropping the archive into Blender or by installing from disk. The current release is version 1.0.3.
Spline Generator is best for blender users who want to generate parametric splines, including attractor-based and mathematical curve shapes, through slider-driven controls.
Spline Generator is completely free to download and use.
Spline Generator is compatible with Blender 4.2 LTS and newer, so it runs on the 4.2 LTS release as well as later versions. The current release is version 1.0.3, published in October 2025. If you are running an older Blender build, you would need to update to at least 4.2 LTS before installing the add-on. Compatibility details are listed on the developer's page alongside the version history.
Spline Generator can be installed by dragging and dropping the downloaded archive directly into Blender, or by using the Install from Disk option in Blender's extensions preferences. The add-on has a small size of around 8.1 KB and requires no special permissions to run. Once installed, its spline creation tools become available through the Add Curve menu in the 3D View.
Spline Generator ships with several presets you can use as starting points. These include the Lorenz Attractor, Rossler Attractor, Dadras Attractor and Halvorsen Attractor, along with Torus and Rhodonea presets. Each provides a starting configuration you can adjust using the slider-based options, with the spline updating dynamically as you change values. Alongside these presets, you can build your own splines across the three categories the add-on offers: Simple, Fractal and Chaotic.
Spline Generator is listed as free in this catalog and is distributed under the GNU General Public License v3.0 or later. For current licensing terms and the latest version, check the developer's page. The add-on requires no special permissions when installed, and its source and issue tracker are hosted on the developer's GitHub repository, where you can also report problems.
