If you had an object with infinite mass and a object with very small mass collide with each other, the object with infinite mass would be considered fixed (won't move) and the object with small mass would retain all the energy it had previous to the collision (assuming perfectly elastic collision). This is what happens in real life, too.
Particles should not bounce against anything, as restitution in Obi is always zero. Also, should not go crazy in any way, unless you've attached particles inside a collider that's also set to collide with the rope (as explained here:http://obi.virtualmethodstudio.com/tutorials/pinconstraints.html) Can you share a video of this?
There's better approaches to pulleys than using a traditional lumped-mass iterative constraint based solver like Obi, if we're talking about all existing algorithms. See for instance our other cable simulator, Filo: https://assetstore.unity.com/packages/to...tor-133620. But as far as Obi goes, this is the best way to simulate a pulley.
Soo, i tried to make it again. And a few days before it worked better. But now i have exactly the same problem. I have know idea why the rope goes flying as soon as a play the simulation instead of staying in the pole.
