Simulating a Hose on a FireExtinguisher

Good evening everyone!

Currently I want to add some physics to the Hose of a FireExtinguisher. which is hold in place on two points (beginning and the end).

The bones in between the beginning and the end should be elastic and affected by gravity/phsics, kinda like in this examples I manually did:

I’ve tried a few different Tutorials on this topic but haven’t found any that’d help me getting the bones that dynamic as this.

My goal is to have the hose adjusting to the start/endpoint depending on where the enpoint moves
Can someone help me out with an example or a tutorial video?

Hmm…
It looks like you have the animation rigging package and you used chain IK for the examples.
I will reccomend you to add a capsule collider a character joint and a rigidbody to all the bones of the hose and adjust them. Something like a ragdoll.

Capsule + Rigidbody + Joint would work, if you need more stability in chain behavior, use ArticulationBody instead.

CCD IK
upd.: according to this video, probably not what you’re looking for, but jacobian Transpose

or you can animate / create the up/down/left/right/fwd/bck etc position anims of the hose
and use them in a blend tree
