Ludwig is a fully rigged and animation ready character for Blender. His features include IK/FK arms, stretch and squash head and spine, and a lip sync ready face controlled by a custom UI. Ludwig was created to provide the Blender community with a high-quality humanoid rig and to promote Blender as a character animation tool.
Ludwig was not designed with the beginner animator in mind. While every attempt was made to keep the controls as user-friendly as possible, functionality was put ahead of ease of use (personal preference played a role as well). That being said, someone new to animation shouldn't have much trouble getting this rig to do what they want it to do. Most of Ludwig's functions are accessible and intuitive.
Ludwig's rig may be used royalty-free for both commercial and noncommercial applications. The Ludwig character may only be used for noncommercial purposes.
