Help Dynamic attachment to fixed object with hinge component

I also thought this might be the issue but to my understanding my collider should be setup properly where that should not be the reason why. In the attached image "Collider" you can see my setup for which I had followed the manual (perhaps I misunderstood something? It looks ok to me).

The collider in your image is clearly intersecting the chain (unless I'm misunderstanding the image) which is what the manual tells you to avoid. So unless you set up collision filtering to disable collisions between the collider and the part of the chain attached to it -I don't see your filter settings in any of the attached images?- then it's rather likely this is the problem.

A simple way to tell whether this is the problem is to globally disable collision constraints in your solver, under the "constraints" foldout. If simulation becomes well-behaved after disabling collisions, then the problem is unwanted collisions.

Removing the stretch compliance sadly does not fully fix the attachment not properly attaching to the bottom hook as seen in image "Attachment issue". It clearly has the attachment as it is angled towards it but its just too far away. I'm not sure how to fix this.

What's the mass ratio between the rope and the platform? as in any engine, high mass ratios require more substeps to converge (you're only using 4 substeps in your solver, I'd recommend to use at least 10 for this). If the platform is much heavier than the rope(s), you'll need to spend more substeps for the simulation to reach an acceptable result. See: https://obi.virtualmethodstudio.com/manu...gence.html

Also I see your solver is using asynchronous mode, which will yield a 1-frame delay with rigidbodies. You should use Synchronous Fixed instead. The manual contains an in-depth explanation of all sync modes and how they bolt on to Unity's physics simulation: https://obi.virtualmethodstudio.com/manu...eloop.html
