how do i blend a ragdoll and a models animation

confusing i know. basicly i want to be able to take my characters walking animation and blend it in with a ragdoll. that way the more hurt he is i can show it by making him more like a doll and go limp over time using a variable. my question is how do i blend current animation with a ragdoll or give the effect of looking more ragdollish?

p.s. yes i know using a ragdoll itself wont work cause all a ragdoll is is a more realistic death simulation.

Making your character "limp" programmatically is not an easy problem to solve. Honestly you'd be better off just making a separate set of "in pain" animations.

On a similar note, when your character does actually die and you want it to smoothly blend with the ragdoll itself, there's this question: http://answers.unity3d.com/questions/12685/rigidbodies-pickup-momentum-from-animation
