Here's a brief overview of how Ragdoll came to be.
In 2012 He joined Framestore and familiarised himself with the world of physics simulation, developing the technology behind the tethers for Alfonso Cuaron's feature film Gravity, and later completed work on the Cloak of Leviation in Doctor Strange.
In 2015 He started a company called Abstract Factory developing tools in Python for use in production pipelines, including Avalon, Pyblish, Qt.py, cmdx and Allzpark; later recieving the "Best Tool" award for Pyblish at the 2020 DigiPro/The Pipeline Conference.
Like Euphoria, WeightShift developed a physically based animation tool, except this one was tailed to Autodesk Maya and got adopted by major feature film studios including Framestore (Harry Potter, Gravity et. al.) and Weta Digital (Avatar, Lord of the Rings et. al.)
In 2020 Epic purchases WeightShift

Sometime in 2021 Ragdoll is released.
