LinkForge earns its place in the blender_extensions library by keeping robot modeling, physics validation, and URDF/XACRO round-tripping inside Blender, with a linter that flags topology errors before export.
LinkForge is built on a mathematically validated Intermediate Representation engine and turns Blender into an environment for authoring robot descriptions. You model a robot, validate its physical integrity in real time, and export code that is compliant and simulation-ready, moving from idea to validated topology to simulation without leaving Blender.
A built-in physical linter flags disconnected links, naming collisions, and unphysical inertia tensors before you export to Gazebo or Isaac Sim. The extension calculates inertia tensors and center of mass offsets using Mirtich/Sylvester algorithms for both primitive shapes and arbitrary meshes, and it imports existing URDF/XACRO files, preserving sensor origins, transmission interfaces, and custom user properties through the Import, Edit, and Export cycle.
LinkForge covers a range of sensors, integrates ROS 2 Control configuration, and extracts repeated geometry into XACRO macros. It runs on Blender 4.2 LTS and newer across Windows, macOS, and Linux, and is released under the GNU General Public License v3.0 or later.
LinkForge is best for robotics developers and technical artists who model robots in Blender and need validated, simulation-ready URDF/XACRO output, from single prototypes to generating many variants in headless RL training loops.
LinkForge is completely free to download and use.
LinkForge is compatible with Blender 4.2 LTS and newer, so current LTS and later releases are supported. It runs on Windows, macOS on both Apple Silicon and Intel, and Linux, and it requires Python 3.11 or later. If you are on a Blender release older than 4.2 LTS, you would need to update before installing. Version 1.4.4 is the current release, published in December 2025.
LinkForge installs by dragging and dropping the downloaded add-on file into Blender, or through the Install from Disk option in Blender's extension preferences. Platform-specific builds are provided for Windows, macOS Apple Silicon, macOS Intel, and Linux, so download the file matching your system. The extension requests permission to import and export URDF/XACRO files, which is how it reads and writes robot description data on disk.
LinkForge includes a sensor suite covering Camera, Depth Camera, LiDAR, IMU, GPS, Force/Torque, and Contact sensors, each with configurable noise models. It integrates ROS 2 Control, letting you configure hardware interfaces, joint limits, and actuation vectors from a centralized dashboard to generate ros2_control configurations. Its physical linter validates topology before you export to simulators such as Gazebo or Isaac Sim, and its XACRO support extracts repeated geometry into macros and shared materials for modular output.
LinkForge is listed as free here in our catalog, and it is distributed under the GNU General Public License v3.0 or later. For current licensing terms and any conditions tied to that license, check the developer's page on GitHub. The extension is available as downloadable builds for Windows, macOS Apple Silicon, macOS Intel, and Linux, installed by drag and drop into Blender or via Install from Disk.
Also in Workflow for Blender.

BlendRef is a Blender add-on for managing image and video references in the viewport while sculpting, animating, or modeling. Its image side works like PureRef or BeeRef, but lives inside Blender instead of a separate app.
by JacquesLucke
Core Debug Tools is a Blender add-on by JacquesLucke that gives core developers a one-click way to visualize dependency graph relations and lazy-function graphs for geometry nodes, bundled with a browser-based dot graph viewer.
by Orange Turbine
Export to Blend is an add-on for Blender that creates a new blend file from your selected objects, collections, or nodes. Exported items can be marked as assets or backlinked into your current scene.
by JuanRomero
Select Similar Geometry is a Blender add-on by JuanRomero that selects objects based on the percentage of matching vertex positions shared with the active object, rather than requiring identical meshes.
by Salt Media
BlenderAe2 by Salt Media transfers 3D data and objects between Blender and After Effects in both directions, covering vertices, 3D layer transforms, camera data and layer synchronization.
by MACHIN3
Machin3Tools is a continuously evolving collection of tools and pie menus for Blender, gathered in a single customizable package. It ships in two base variants, Prime and DeusEx, with the DeusEx variant adding more advanced tools.
by MikhailRachinskiy
3D Print Toolbox is a Blender add-on with utilities for 3D printing. It analyzes mesh volume and surface area, checks and fixes geometry, hollows shapes, aligns models to the print bed, and exports to STL, PLY, and OBJ.

UVPackmaster 4 is a UV packing engine for Blender that packs UV maps on the CPU and GPU, using the Cuda and Vulkan APIs, and can run on the CPU and all system GPUs at once.
by MMD
MMD Tools is a Blender add-on for editing MikuMikuDance (MMD) models. It handles importing and exporting model, motion and pose data, along with chopping and joining parts, plus rigid body, material and motion editing.
