In 2020 you are probably better off creating a Dead animation state, taking a snapshot pose of the mesh when it’s finished bouncing around (which should be implemented manually during the “ragdoll” state), and putting the mesh in that state.
I’m not 100% done with my system or I’d share some more details about it, but suffice it to say, that you can use physical animations instead of simulating physics without any control of the rigidness of the different bodies.
Another thing to note, to prevent the meshes from spazzing out I ended up scaling the tensor from the extremities inwards with X values of 5,4,3,2.
You and anyone else can mostly follow the live training for it.https://youtube.com/watch?v=N1tDjbFXeOo
There are a few gotchas that you may come across, but anything is better then leaving the actor in a ragdoll state, performance wise…
