Caveman Available at: Caveman has been developed using Blender 2.5. From its first stage of cube subdivision modeling to the final Video compositing and rendering, all within Blender. This is a friendly rig, easy to use and automatic muscle ready. Legs, biceps and triceps are automatically contracted or expanded with arms or feet movement.  I recommend the last release of Blender ( 2.57 up to today ), very stable and ready to download from the Blender site. Caveman V1 as well as the other rigs shown are available throughout our website. Thanks for watching, do not forget thumbs up !
