Modular Tree earns its place in the blender_extensions library as a dedicated tree generator that pairs one-click presets with a node-based procedural workflow. Now at version 5.5.2, it supports Blender 4.3.1 and newer across Windows, macOS and Linux.
Modular Tree, also known as Mtree, is a Blender add-on for building 3D trees. It generates a tree by executing a succession of tree functions that shape the structure, then converts the result into a 3D mesh.
For quick results, one-click presets cover Oak, Pine and Willow. For finer control, a node-based workflow lets you build trees by connecting nodes, while procedural parameters govern the trunk, branches and leaves. Chaining branch nodes produces multi-level branching for more complex tree structures.
Beyond the add-on, Modular Tree is built on a C++ library that can be used separately. It runs on Blender 4.3.1 and newer, with downloads for Windows, macOS on both Intel and Apple Silicon, and Linux, and is licensed under the GNU General Public License v3.0 or later.
Modular Tree is best for blender artists generating 3D trees, from quick preset-based results to node-driven procedural setups with control over trunk, branches and leaves.
Modular Tree is completely free to download and use.
Modular Tree lists compatibility with Blender 4.3.1 and newer. Downloads are provided for Windows, macOS on both Intel and Apple Silicon, and Linux, so you can pick the build that matches your system. If you plan to develop the add-on rather than simply use it, the project notes Blender 2.93 or higher along with Cmake as a dependency. For the current release and platform-specific files, check the developer's page on GitHub.
Modular Tree can be added by dragging and dropping the downloaded file into Blender, or by using Blender's Install from Disk option in the extensions preferences. Separate builds are available for Windows, macOS Intel, macOS Apple Silicon and Linux, so download the one that matches your platform first. The developer's page links to the current release files, and Blender's own documentation covers the installation steps in detail.
Modular Tree is listed as free in this catalog. The Blender add-on is released under the GNU General Public License v3.0 or later, and the underlying Mtree library carries an MIT license. Licensing terms can change over time, so it's worth checking the developer's page on GitHub for the current release files and any details before relying on it in a project.
Modular Tree ships as a Blender add-on, but it is built on a C++ library that can be used separately. Developers who want to work with that library directly can clone the repository recursively and build it, which requires Cmake, plus Blender 2.93 or higher if you also intend to develop the add-on itself. Full setup steps are documented on the developer's page on GitHub.
