The LazyCat Jitter Cleaner add-on provides a workflow to eliminate the continuous vibration and shaking often found in resting objects during Blender's rigid body simulations. It works by first baking the physics simulation to keyframes, then applying an adjustable Gaussian smoothing algorithm across the animation data.

The tool supports batch processing for handling large numbers of objects simultaneously, such as debris, falling items, or domino setups. Users can adjust the smoothing strength using a slider to suit different object types, maintaining the overall realistic motion while stabilizing resting states.
