Ragdoll Dynamics

Ragdoll Dynamics Ragdoll Dynamics

Animate with physics

Join us in Vancouver on August 9th to 11th for SIGGRAPH 2022!

An Autodesk Maya plug-in for feature film and games animators on Windows, Linux and MacOS.

Dynamic Characters

Let the computer handle weight and contacts.

For Dynamic Performances

Focus more on what characters to do, less on how they do it.

Look ma', it's real-time!

0-5 ms per frame; you've got a total
of 33 ms for 30 frames per second.

"Ragdoll finally lets me focus on the creative side of an animation. I can iterate on an idea quickly with realistic results in half the time that would be needed with traditional keyframing - A must have for any studio."

"The most artist-friendly dynamics tool made for animators; fast, easy to setup and the simulations look great. Overall a huge time saver for animators."

"I find Ragdoll Dynamics a fantastic way to generate overlapping animation and quickly and intuitively iterate on it. The tool provides solid dynamic simulation with little overhead, straight on the animation controls. As an animator, this is something I have always dreamed of."

Animation Tutor

"Ragdoll is surprisingly effective at giving a simple solution to a very complex situation. From simply having fun with physics to total production saver and from simple simulation chains to the most complex of characters, Ragdoll's got your back!"

Animation Supervisor

"Ragdoll IS awesome! Not just a really effective tool, but also fun to use."

Simulate NURBS controls, locators, polygons and empty groups

Anything your character rigs are made of.

General-purpose physics solver

Anything with a translate and
rotate channel can be simulated.

from maya import cmds
from ragdoll import api as rd

cube, _ = cmds.polyCube()
cmds.move(0, 10, 0)
cmds.rotate(35, 50, 30)

solver = rd.createSolver()
marker = rd.assignMarker(cube, solver)

cmds.evalDeferred(cmds.play)

First-class Python API

For rich integration with any production pipeline.

Bring physics out of Maya..

..and into Unreal, Unity, Motion Builder,
Blender, you name it.
