Free KineFX rig and masterclass videos
Software used: Houdini
SideFXhas released a video series that demonstrates how to combine keyframe animation with ragdoll simulation and secondary motion on a character in Houdini. The videos give an overview on KineFX rig setup and logic, then it goes to show keyframe animation and how to use that block-in animation to run a ragdoll sim and secondary motion for added detail to a character. A free elephant rig and .hip file (which has the animation and ragdoll sim setup) is available. Find out more on the SideFX website.
