Help Obi Rope Lenght Problem

[relevantname]

Yes. Ropes have a particle pool from which they take particles to increase their lenght or be torn. Once all particles in the pool have been used up you can no longer extend the rope. This is done to avoid runtime memory allocations.

You can change the size of the pool in the rope's blueprint. See:

I tried to increase it, but no effect at all. Btw, I increase the lenght of the rope to some object's position, then pin the last particle to some object. It works but when the object is pinned to the rope, the rope strectches like rubber. How can I prevent that? 

And my other question is; under what conditions should I change the mass of the rope(or should I change?)?
