Hi everyone,

Please see as follows:

- [Babylon.js/packages/dev/core/src/Physics/v2/ragdoll.ts at aa48d7991044cb0d15054edf61a55c4a99182d89 · BabylonJS/Babylon.js · GitHub](https://github.com/BabylonJS/Babylon.js/blob/aa48d7991044cb0d15054edf61a55c4a99182d89/packages/dev/core/src/Physics/v2/ragdoll.ts#L240)

> `rotationAxis` defines the axis that will be constrained in angles. `min` and `max` define these limits.  
> ([Babylon.js docs](https://doc.babylonjs.com/features/featuresDeepDive/physics/ragdolls/))

The limits never enter the PhysicsConstraint. Nothing breaks or crashes. But missing rotation constraints make the ragdoll useless outside comedic games.

After some more research maybe this is rooted in the absence of limits in the prefab constraints? So neither the base [PhysicsConstraint](https://doc.babylonjs.com/typedoc/classes/_babylonjs_core.PhysicsConstraint) nor e.g. [Hinge](https://doc.babylonjs.com/typedoc/classes/_babylonjs_core.HingeConstraint) or [BallAndSocket](https://doc.babylonjs.com/typedoc/classes/_babylonjs_core.BallAndSocketConstraint#options) offer any sort of limit. Only the [6DOF](https://doc.babylonjs.com/typedoc/classes/_babylonjs_core.Physics6DoFConstraint#constructor) constraint has an extra limits array in its constructor.

But that is not too great either, and doesn’t help with the ragdoll.

Best wishes  
Joe

I’ll take a look asap
