is there a way to make a controllable active ragdoll (like in gang beast or human fall flat) using Unity’s ragdoll wizard?
There’s no built-in way. Typically people would script some sort of system where they switch between a typical controller/animation system with a ragdoll system and blend bone positions in between. So far I’ve never attempted such a thing on my own, but there are several systems on the Asset Store.
Edit: also, I believe that Human:Fall Flat was actually made with Unity, so it’s certainly been done before.
