This blender addon script is loosely based on the short academic paper “Raycast based auto-rigging method for humanoid meshes” by Romain Lopez (ESGI Paris) and Christophe Poirel (ESGI Paris). Radiant Rig XL is the latest version of Radiant Rig. This script requires blender 2.76 or higher.

You must have Rigify installed and activated in order to use this addon. Radiant Rig automatically creates a human meta-rig sized to fit the selected figure. This script works best with figures with tight clothing. The “Split Mesh” feature will assist with rigging clothed figures.The script rigs the mesh within 10 seconds to 1 minute for most figures I’ve tested. This script also works with Pitchipoy’s version of rigify but please only have one active version of Rigify in your blender install. Two different versions could cause conflicts. I have also added controls to select individual fingers for improved rigging. Requirements: Based on my tests and other users feedback, this addon is processor intensive. You will need at least a 2-core processor and 4 GB of RAM for reasonable execution time.

This script works best with meshes in T-Pose that have space between the legs and hands flat facing down. There should be space in between the fingers. The figure should be standing up not laying on the ground. The figure should be facing front. The figure should also be hollow. Stray vertices inside the mesh can wreak the calculations.

This script will not work on meshes made up of parts. The figure must have one main body part with limbs and head connected. The interior must be smooth. Clothing can be a separate mesh on top of the main mesh but breaks in the main mesh will cause problems for the calculations. Radiant Rig is blind. It calculates the boundary of the figure by tapping around it to find out where to place the armature. Breaks in the edge wreak the calculations. Radiant Rig works best with completely hollow meshes with no breaks between parts.

I’d like to provide my own meta-rig that corresponds to a
different animation system. Are there directions for providing
a different bone file in FBM or BVH format?

Unfortunately, no. The software is only aware of two rigs, rigify and pitchipoy’s version of rigify. I could alter it to accept any rigs but that would take time. When I update the software I’ll tweet it @4colorgrafix.
I rescind my earlier comment. Radiant Rig XL now has beta support for other rigs. You must match up your rig to a rigify style rig. See the youtube video above for details.

Hi Kofi,

I’d like to integrate radiantrig into my 3d body scanning process to create auto-rigged models of people in a few minutes 🙂
I can’t install radiantrig XL and get this error:

Please can you let me know where I’m screwing up?

Thanks!

I was only able to replicate your error by using Blender 2.74; is there any reason you are using an older version of Blender? The addon will activate in Blender 2.77 and Blender 2.76.

Stephan emailed me back:

“… I didn’t realise I was using 2.74 by mistake because I have 2 versions installed! Thanks for your help!”

Radiant Rig XL was updated for this issue on April 3, 2016 and again on April 4, 2016. I’ve updated the notice at the top of the page to make this more clear.
