Smooth animation to Ragdoll transition

Im now trying to achieve smooth full body ragdollisation on 4.8 TPS example character, but when the physics blend is set to 0.0 (ie rigid state) my character starts spinning violently. It doesnt happen when it is in ragdoll state.
Is there a way to achieve this without modifying the engine?

I would like to know that as well. I have just posted a video showing (probably) the same problem: - YouTube

It’s even spinning if you change the bone name from “b_Spine” to “b_Hips” in the “PhysicalAnimation” map of the “ContentExamples” from the learn tab (tested with 4.7 and 4.10). I think this is expected behaviour because you are mixing a bit of 0.5 (means false) physic with a bit of animation (too less to let it still float) and there is no bone left that keeps your skeleton magically upwards like it would be the case if you just enable physic to spine and both legs.
