Radiant Rig basic is my implementation of the paper “Raycast based auto-rigging method for Humanoid meshes” 
by Romain Lopez (ESGI Paris) and Christophe Poirel (ESGI Paris). It works only in Blender 2.6.8 and 
above. Radiant Rig basic depends upon Rigify. Radiant Rig basic automatically creates a human meta-rig sized to 
fit the selected figure. Download Radiant Rig basic here http://4colorgrafix.net/bpy.

Installation
Rigify comes pre-installed in Blender. It needs to be activated in order for it to work with Radiant Rig basic.

1) Go into User Preferences (Windows CTRL+ALT+U or Macintosh CMD+,)
2) Click on “Addons” and search for “Rigging: Rigify”. Make certain there is a checkmark beside Rigify.
3) Click on “Install from file” and select the downloaded Radiant Rig basic Zip file.
4) Click on the box beside “Rigging: Radiant Rig basic” to active Radiant Rig basic.
5) Click on “Save User Settings”.

Preparation
Please ensure that your selected figure has the following properties:
1) Is humanoid.
2) Is hollow.
3) Is (mostly) symmetrical.
4) Limbs are NOT covering each other.
5) Legs have space between them.
6) Feet are on ground.
7) Fingers have space between them.
8) Hands are spaced away from the torso.

Usage
1) Load your figure into Blender.
2) Click “Generate Auto-Rig”.
3) You might get the following message:

   Calculation Error. Unable to find all limbs.
   Possible Causes:
   * Limbs are covering each other.
   * Not a humanoid figure.
   * Clothing mesh on top of figure: Try with split mesh.

4) Click on “Split Mesh”
5) When the splitting is complete, click on “Generate Auto-Rig”.
6) Once rig calculation is complete, a new rig based on the Human Meta-Rig will be generated.
7) Your rig is now attached to your figure.
