Help Knot in suturing simulator

[manurocker95]

Hi!
I'm currently developing a suturing simulator for medicine students, and I'm having big trouble finding a way to replicate this exercise in my app (https://www.youtube.com/watch?v=DIUy3jeM6sY). As you can see from this second video (https://www.youtube.com/watch?v=5ZXG9LiYFdc), even with self and surface-based collisions activated and using only distance fields for collisions, the rope passes through itself and objects, making creating a knot impossible. Do you have any suggestions to solve or "bypass" (IDK, maybe dynamically substituting the rope blueprint with a "baked knot" by hitting a controller button at the right time?) this problem?
In the attachment, you can find screenshots of the solver and rope parameters.
Thank you for your attention!

I'm making a similar thing and I'm facing the same issue. In addition, when going through the "skin", the particles inside the skin object get really crazy. Any idea about how to achieve that?
