Help How to make a knot?

[zxinlong]

Hi there!

I highly doubt doing this in realtime is even possible. The sheer collision resolution and amount of iterations needed to robustly support this use case is way too high. By cranking up rope resolution (ObiRope->resolution->Initialize), distance and particle collision constraint iteration count (ObiSolver) and by reducing the physics timestep (ProjectSettings->Time->fixed timestep), you will be able to make a few knots under little tension.

However increasing rope tension over a certain threshold (higher the more time you spend solving physics) will undo any knots in the rope.

cheers,

Hi, Jose!Thanks for helping me.

I successfully made a knot according to your method, but now I have some new problems:
1. There is a large gap in the knot, resulting in the rope cannot be close together;
2. The rope has been shaking and cannot stop.
Is there any way to make the rope itself close together quietly?
