Three types of character primitives: child/cartoon, realistic man, and monster proportioned character models. This plug-in is to make it easier for character modelers to get started. The models have the correct proportions and extra geometry in useful places around the face and joints.
Stan Rig is a flexible toony character rig that has many features including a full facial rig and appeareance modifiers. This rig also comes with an easy to use and install GUI.
This tool allow you to easily rig a machanical spider leg with both Ik and Fk systems; The rotations of joints in the leg appens so they can only rotate on their bending axis leaving the twisting and side2side rotation to the upper joint of the hierarchy. In this way the parented geometry will not break during the leg movements.
