How I got Ragdoll animations into blender,C4D,Daz,Iclone, Maya
Spend $129 on this vestigial program
https://www.posersoftware.com/store/products/69
Download FREE open source Python3 ragdoll simulator
for that vestigial program.

Run various ragdoll collision simulations with default figures of that
vestigial program, as I have been doing for 14 years.
Export to FBX and retarget to blender ARP rigs
or Rigify (with addons like Expy kit or Rigimap)
$129 may sound like alot for an entire application used for one single purpose but you can recoup your investment by selling animations to the Game dev community or Daz markets.
