How to make an R15 rig have cartoony physiques?

I’m trying to make an R15 character behave like a soft, floppy ragdoll, similar to games like Human Fall Flat, Gang Beasts, or Party Animals.

I want the character’s body to bend and react dynamically to external forces at all times, rather than just ragdolling after pressing a keybind. The character should always have these fun, wobbly physics, and then optionally be able to fully ragdoll when needed.

For example, I want:

  • If you grab and pull the head, the rest of the body follows naturally.
  • If a heavy object falls on the character, it bends under the weight instead of just using the default “laying” state, which looks stiff.

I’m aiming for a smooth and fun physics-based movement, similar to how plushie-like characters move in these physics-driven games.

What would be the best approach to achieve this with an R15 rig?
Any guidance would be greatly appreciated!

this is called active ragdolls
roblox recently did a beta feature called joint upgrade, its quite literally what you want!
