Easy Jiggle is a Blender addon that adds physics-driven jiggle and bounce to mesh objects. Define a region on your mesh and it sets up soft body physics that reacts to movement and gravity.

BSnow is a Blender add-on from IK3D that adds snow to existing models such as landscapes, rocks, statues and foliage, with granular control over domains, temperature and physics for building winter scenes.

Real Eye Motion is a Geometry Nodes setup for Blender that produces realistic character eye movement without keyframes. It works on any character with Eyelid and Eyeball bones, including Human Generator and Daz3D rigs.

Fluid Flow is a Blender add-on for realtime physics simulation of water, sand, and lava directly in the viewport. Built with Geometry Nodes, it runs without baking and gives artists slider-based control over flow.

Quick Cloth is a Blender add-on from NTE Studio that gathers cloth simulation settings into one menu. It spawns cloth and pillow meshes, converts text to cloth, and exposes tearing, pinning, collision and physics controls.

FLIP Fluids is a liquid simulation addon for Blender that lets you set up, run, and render high-quality liquid effects. Its custom FLIP-based engine has been in development since 2016 with tight Blender integration.

Simply Cloth Studio 2 is a cloth creation and simulation add-on for Blender, rebuilt for Blender 5.0 with a modern interface, an adaptive wrinkle recognition system, and performance improvements, alongside tools for pinning, sewing, and cloth presets.

RBDLab is a VFX and simulation addon for Blender, developed by BeFX Studios for rigid body and destruction work. It ships with documentation and free updates, and holds a 5-star rating from 70 reviews.

Physical Open Waters - Ocean is a Blender add-on from Physical Addons for infinite ocean simulations, offering advanced LOD stability and dynamic wave interactions. It renders in both Cycles and Eevee.

Jiggle Physics adds stretchy jiggle physics to Blender rigs. A fork of the Wiggle 2 add-on by shteeve3d, it uses a verlet solver with simple 0-1 parameters to animate anything from soupy ropes to immovable rods.

X-Muscle System is a physics-based tissue simulator add-on for Blender, built for creating muscular systems, tissue and organic objects and running physical simulations that visualize skin surface deformations based on volume preservation of muscles, fat and bones.
