Radiant Rig is my implementation of the paper “Raycast based auto-rigging method for Humanoid meshes” by Romain Lopez (ESGI Paris) and Christophe Poirel (ESGI Paris).
Rather than type out text tutorials, I thought I would collect links to some of the best video tutorials for Blender. Most of the tutorials give tips for rendering but the last tutorial shows how to use GoB, an unofficial GoZ for sending models between Blender and ZBrush.
In ZBrush tools can’t be retopologized without destroying existing 3D layers. In Blender, objects can be retopologized and existing Shape keys will be altered accordingly. The altered base object and its shape keys can then be reimported into ZBrush. The conversion is tedious work.
