[spikebor]

Hi, pls take a look at this video



package: https://drive.google.com/file/d/1WNSuRz9...sp=sharing
In this you will find the scene: Assets/Spike/Scenes/Cut the Rope.unity
In the scene you will have the rope cutter object Rope Cutter with script RopeCutOnCollide.cs
and the masterSolver object with script ObiContactDebug.cs

First part of the video, everything is fine, the rope cutter can cut rope at exact element.
But when it hit the softbody ball, it also treated as hit the rope.
