ProxyBody

is a Blender add-on that creates optimized proxy meshes from your 3D models for faster, smoother rigid body simulations. It reduces scene complexity, improves playback performance, and makes it easier to achieve great high-poly real-time simulation results with a more efficient workflow.

Main Features:

Create Optimized Proxy Meshes

Generate lightweight proxy versions of your models for faster simulation and better scene performance.

Flexible Placement and Randomization

Place proxies with array and surface tools, then add natural variation with built-in randomization controls.

Efficient Simulation Workflow

Convert placed proxies into simulation-ready objects and use them to drive a high-detail result with a faster workflow.
In this example you have 60 cars being simulated in real time.

Or You can even Simulate a THOUSAND cars!
