I am not very experienced using the Bullet dynamics system, and I have come across a job project where I am setting up an animation of a bracelet that has several decorative parts hanging off the main bracelet part, and figured the best approach is to use dynamics to simulate them moving realistically when rotating the bracelet.
However, I am really struggling to make this work. I have set up a simplified test file where I have a Collider object in the shape of a torus acting as the attachment part on the bracelet, and then a hanging "tag" dynamic object.
I have tried adjusting the Collision Margin, Scale and Steps Per Frame in the Bullet Expert settings , and played around with a massive amount of different settings in the Collision/Mass/Force tabs on the Dynamics Body tag of the dynamic object, but none provide a stable solution. The dynamic object either jitters or starts tilting oddly, seemingly regardless of settings chosen.
I have read that scale might be an issue here, but changing scene scale is not really an option as that would cause a whole lot of headache with other scale dependent parts of the scene.
I have attached my current test file. Any help with figuring this out would be massively appreciated as I have really hit a wall here and I see the deadline on the horizon.
Thanks in advance!
