Rope/Rod gets stuck inside mesh collider

[Wattosan]

Don't use MeshColliders, specially not concave ones as they're "hollow" (once an object gets inside of it, it does not get automatically projected outside).

Use distance fields instead. They're much cheaper and way more robust:

Thank you! It indeed is more reliable now. 

One question, does the reference of Source Collider in the inspector of Obi Collider to the Mesh Collider have to remain, even after ticking Use Distance Field and giving the correct reference? I see that it automatically sets the reference if I set it to null. I understand that the distance field works because it is more reliable but does having the reference to the mesh collider reduce performance?
