This blender addon 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 5.0 is the latest version of Radiant Rig. This script requires Blender 2.79 or Blender 2.80. 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 2 minutes for most figures I’ve tested. With Blender 2.79, Pitchi Poy’s version of Rigify has been merged with the old Rigify so there is no longer a need to install it separately. I have also added controls to select individual fingers for improved rigging.


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. 4-cores or higher would be better. 8 GB of RAM or higher would be better.

This script works best with solid meshes in A-Pose that have space between the legs and fingers naturally bent. There should be space in between the fingers for better detection. The figure should be standing up not laying on the ground. All modifiers should be applied before execution. The figure should be facing front. The addon works best on hollow symmetrical meshes.

The figure must have one main body part with limbs and head connected. The interior must be smooth. Thin clothing is fine but thick clothing should be a separate mesh parented to the main mesh. Radiant Rig is blind. Radiant Rig works best with completely hollow meshes having no breaks between parts. Results may vary depending on the mesh you use.

Personal message

This addon represents hundreds of hours of development time. I ask that you do not re-distribute it. The only officially supported version is the one purchased from Gumroad. I will deliver all software updates through Gumroad. If you obtained it from another source, others might have altered it. I will not support altered versions of the software.

Make sure that what you downloaded is the real version by checking the shasum in the terminal.

Mac in terminal: shasum -a 256 /path/to/file
Ubuntu in terminal: sha256sum /path/to/file
Windows in Powershell: Get-Filehash -path c:\path\to\file -algorithm SHA256 | fl
