Ragdoll ships as a Maya Module for Windows, Linux and MacOS.

Installation for Windows

On the Windows platform, there's an executable you can run.

  1. Run the .msi installer
  2. Restart Maya

Alternatively, download the Linux distribution above and unzip it into your ~/maya directory. You should end up with something like this.

Installation for Linux

On Linux, installation and upgrades are done in the same fashion.

  1. Unzip the .zip into your ~/maya directory
  2. Restart Maya

You should end up with something like this.

Installation for MacOS

On MacOS, installation and upgrades are done in the same fashion.

  1. Copy the contents of /modules into /Users/Shared/Autodesk/modules/maya
  2. Restart Maya

You should end up with something like this.




Ragdoll is still in the process of being verified by Apple, until then you may need to tell Gatekeeper "everything is OK" for both the ragdoll.dylib which is the physics solver, and loco3d which is the Locomotion module. It may also ask about TurboFloat and TurboActivate which is the licencing system.



The plug-in is now available via the Plug-in Manager.

Everything ok?

No menu

You've booted up Maya, loaded the plug-in via the Plug-in Manager, but there is no menu, what gives?

Maya Modules work in mysterious ways. Try installing it the old fashioned way.

from ragdoll import interactive
No module named 'ragdoll'

A clue! Let's go deeper.

import os
modules_path = r"c:\Users\marcus\Documents\maya\modules"
ragdoll_path = os.path.join(modules_path, "Ragdoll-Maya-2021_11_06\scripts")

import sys
sys.path.insert(0, ragdoll_path)

from ragdoll import interactive

Make sure you replace the version number (date) with the version you are using. At this point, I expect you've uncovered why your module wasn't working in the first place and should probably revisit that as this process would require you to manually update the version number in that path each time you upgrade. No fun.

Something else happened

Oh no! I'd like to know about what happened, please let me know here.


What are my workstation requirements?

Anything capable of running Maya can run Ragdoll.

  • Windows 10+ or CentOS 7+
  • 64-bit Intel® or AMD® processor
  • 4 GB of RAM
  • Maya 2018-2022
What are my licensing options?

See Pricing.

What happens when my licence runs out?

Your scenes will still open, but the solver will be disabled. Contact for renewal of your licence.

What happens when I skip frames?

The simulation gracefully pauses until you revisit the last simulated frame. See the Frameskip Method attribute on the rdSolver node for another option, Ignore. This will continue simulating, and ignore any skipped frames. Good for real-time playback with audio.

Can I use Rez?

Yes, the only environment variable needed for Rez is MAYA_MODULE_PATH, such as:


Where the Ragdoll-2021_07_28 folder and Ragdoll-2021_07_28.mod file resides at {root}.

Why not use nHair for overlapping animation?

Ragdoll simulates your translate and rotate channels, whereas nHair simulates point geometry. You can convert those points into translation and rotation, but given the choice why would you? Besides, Ragdoll has far more robust collisions, control and constraints than nHair or nCloth could ever hope to achieve, at much greater performance.


As of Ragdoll 2024.02.29 these are the current known limitations of Ragdoll.
