Space colonization tree generator earns its place in the blender_extensions library for a focused, algorithm-based approach to tree generation, implementing a published space-colonization method in a lightweight add-on.
Space colonization tree generator is a Blender add-on from LS that generates tree-skeletons using the space-colonization approach. You select an input mesh, and the tree grows into it. The implementation follows the space-colonization method introduced by Runions, Lane and Prusinkiewicz (2007).
The add-on requires no special permissions and works with Blender 4.2 LTS and newer. It's a small download at 6.6 KB, distributed under the GNU General Public License v3.0 or later. Installation is by drag and drop into Blender, or by downloading and installing from disk.
One reviewer, who rated it five stars, noted it took some getting used to but used it to create coral formations. Since its release in July 2025, the add-on has been downloaded more than six thousand times. Issues can be reported on the developer's GitHub page.
Space colonization tree generator is best for blender users generating tree-skeletons that grow into a selected input mesh; one user applied it to coral formations.
Space colonization tree generator is completely free to download and use.
Space colonization tree generator lists compatibility with Blender 4.2 LTS and newer, so it runs on the 4.2 LTS release and later versions. The current release is version 1.0.0, published in July 2025. If you're on an older Blender build, you'd need to update to at least 4.2 to use the add-on. Compatibility details are shown on the developer's Blender extensions page, which is the best place to confirm before installing.
Space colonization tree generator can be installed by dragging and dropping the add-on into Blender, or by downloading the file and installing it from disk through Blender's extensions preferences. The download is small at 6.6 KB. For step-by-step guidance on installing from disk, Blender's own documentation covers the process, and the developer's page provides the download link and further details about the add-on.
Space colonization tree generator is distributed under the GNU General Public License v3.0 or later. It's listed as free here, and the add-on requires no special permissions in Blender. For the current licensing terms and any usage conditions, check the developer's page. The source and issue tracker are hosted on GitHub, where you can also report problems or review the project details.
Space colonization tree generator does not require any special permissions, as stated on its listing. That means it doesn't request extended access when you install it in Blender. The add-on is compatible with Blender 4.2 LTS and newer, and at 6.6 KB it's a small install. If you run into problems, the developer maintains an issue tracker on GitHub for reporting them.
