Spriter character with physics ?

Hi.

Is it possible to add physics to my spriter character after I have it imported to C3?

I want my character to have physics enabled only when he dies, so that it looks more realistic.

I've searched for step-by-step tutorials on google and youtube... but there's nothing.

I really doubt this will work..

When the character dies, you can probably replace it with a "ragdoll" made of the same pieces, but connected together with physics joints. And let it collapse to the ground with physics.

Well, yes, It's not what I'm looking for :)
