Proxybody earns its place in the Blender library for a focused job: turning heavy 3D models into lightweight proxies so rigid body simulations stay responsive. The array and surface placement, randomization controls, and conversion to simulation-ready objects cover the full proxy-to-result path, and the sixty- and thousand-car examples show the scale it's aimed at.
Proxybody is a Blender add-on from PlugIn3D that creates optimized proxy meshes from your 3D models for rigid body simulations. By generating lightweight proxy versions of your objects, it reduces scene complexity and improves playback performance, making high-poly real-time simulation results easier to reach through a more efficient workflow.
Placement is handled with array and surface tools, and built-in randomization controls add natural variation across your proxies. Once positioned, those proxies convert into simulation-ready objects that drive a high-detail final result. The listing points to examples running sixty cars in real time, and even a setup simulating a thousand cars.
Proxybody is listed for Blender version 5.0 and supports both Cycles and Eevee. It ships under the GPL license, comes with documentation, and a demo video is available. For rigid body work where scene weight slows playback, the proxy-based approach keeps performance manageable while still driving a detailed final result.
Proxybody is best for blender artists building rigid body simulations with high object counts, where proxy meshes help keep scenes light and playback responsive.
Proxybody is completely free to download and use.
Proxybody is listed for Blender version 5.0, so that's the release it's built to run in. It works as a Blender add-on that generates proxy meshes for rigid body simulations directly inside your scene. If you're running a different Blender version, check the developer's page before installing to confirm it behaves as expected, since the listing specifies 5.0. Keeping your Blender install aligned with the stated version is the safest way to get the placement, randomization, and simulation-conversion tools working the way they're described.
Proxybody lists Cycles and Eevee as the render engines used, so both of Blender's main engines are covered. The add-on creates optimized proxy meshes, places them with array and surface tools, and converts them into simulation-ready objects that drive a high-detail result. Whether you render in Cycles or Eevee, that proxy-based simulation workflow is what the add-on handles. For confirmation on specific engine features or settings, the developer's page is the place to check current details.
Proxybody is listed as free in this catalog, so you can add it without a purchase here. It's released under the GPL license, and the listing also notes Proxybody as a Dev Fund Contributor. Licensing and availability can change over time, so if you need the current terms or want to support the developer directly, the developer's page is the best place to confirm. For the most accurate, up-to-date details on cost and rights, refer to the developer before installing.
Proxybody places proxies using array and surface tools, then adds natural variation with built-in randomization controls, which is how it handles large numbers of objects in a scene. The listing points to examples of sixty cars simulated in real time and even a thousand cars, showing the kind of scale the proxy workflow targets. Once placed, the proxies convert into simulation-ready objects that drive a high-detail result. This proxy-based approach is meant to reduce scene complexity and improve playback performance during rigid body simulation.
