This is my first charterer rig in blender, named "Red-Nelb", is free to use it but  currently is in version 0.4, that's means to things:  -it´s no ready for production  - miss some standard features like Fk in Arm/Leg (now only IK), stretchy, etc..   I´m working in a completely rebuild of Arms and Legs So, use at your Risk!    "Red-Nleb" is a excuse to test and implement rigging comcepts, in this version the  focus is in to use the minimum controls in viewport without lost functionality.    Have fun DOWNLOAD
