A rope you can climb, swing on and jump from. Something similar to this:

    CryptoMares i'm assuming you want that replicated in Godot.
    a rope is possible with some RigidBody3D and Bone hackery. it's demonstrated here:

    you could repurpose the above technique on a chain model as well, or really any noodle shaped object.
    if you're looking for realistic chain physics, only God can help you here.

    as for climbing that stuff, that gets complicated extremely quickly, but i hope this gives you ideas.

        packrat This is only a visual part of the problem, I'm more interested in the mechanic itself - how will I jump on it, swing from it, how will I jump from rope to rope and how the the second rope will react to my momentum, how can I create a procedural asset from it - stuff like that. I don't need any "realistic" chain or rope physics - I just need to be able to make it feel good, gameplay-wise. The visual is pretty much secondary, but of course I would like to make it look as good as I can.
