Corrected an error with some T-pose figures.

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 to 2.79.
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. For Blender 2.76 to 2.78, this script also works with Pitchipoy’s version of rigify but please only have one active version of Rigify in your blender install. With Blender 2.79, Pitchipoy’s version 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. 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. Results may vary depending on the mesh you use.

This blender add-on moves the selected object(s) to the centre of the ground plane.
This blender add-on finds the lowest point on the selected object(s) and aligns that lowest point to the ground plane while maintaining relationships between selected objects.
This blender add-on resizes the selected object(s) to fit within the specified maximum height. Proportions are maintained for all selected objects. The Default maximum is 2 Blender units but this can be changed by clicking on the text.
