Most example scenes have objects of relatively low mass, how to increase the rope's strength to deal with objects of higher masses like 100 or more?

From what I see rope thickness directly impacts its behaviour and power, but why is it exposed on the blueprint and not on the rope object itself? Can't change thickness on runtime?

Is it possible to change the mass of the particles too?

I have a multiplayer game and I am wondering if the cloth is replicable from server to clients.

I asked before about obi rope and an admin answered me its possible with rope, is it possible with cloth too?

Also ca cloth be used to make a trampoline and have rigidbodies bounce on it realistically?

Hi, when I deactivate the emitter component it stops emission while also destroying the emitted particles. Is it possible to only stop emission, while keeping the already emitted particles alive until their lifetime ends? Kind of like turning a tap on and off without destroying the water already in the sink.

I am developing a server auth multiplayer game and I need to send rope data to clients to render the rope locally, is this possible?

Hi,

I made a scene with a rope that is pulled on both sides. At the start its size is 4.28 m and later when attachments pulled it we see in unity a size of approximatly 15 m but rest length still show 4.28 m (see https://imgur.com/a/9YfSQc6).
Is there something that I don't understand with rest length ? I based my thought on Changing rope length at runtime: ObiRopeCursor : "It is very useful to know the current length of the rope when working with cursors. Use the rope's RestLength property for this.".

Thanks in advance,

Hi,

I add a rope which have a weird behavior : https://imgur.com/a/hAXi6YA
It seems like that it's simulated twice, but there is only one ObiFixedUpdater.
Have you an idea of what could generate this ?

Thanks in advance,

Hello,

So after buying Obi rope I also checked Filo cable.
I wanted a scene where the cable/ rope is not too flexible as in the case of Obi rope, however I also want the cable sag (which is there in Obi rope and I dont see it in the filo cable).

So I am not sure if Filo cable can have cable sag.

I want a spool on which the cable is stored (same as in the spool example of Filo cable) with a pulley as shown in the figure.

Also the simulation is super slow and I am not sure why. The floor is of scale 100-1-100 and the 2 spool-pulley system is at the 2 corners of the floor.

Any help is greatly appreciated.

Thank you.

sorry. My English is poor.

What I want to achieve and what I have tried.

1: Wrap a heavy frying pan in a plastic bag.
-> I used the ClothSoftBody Sample Scene as a reference. By adding obi cloth to the cube and reducing the Volume Constraints, it looks like a plastic bag. Please let me know if there is a better way.

2: Tie the handle with a rubber band
-> I can't think of a way.

3: Even if thrown into a box from a height of 10cm, the plastic bag will not break.
->I've tried increasing the surface collision and particle mass. However, it doesn't work well because the frying pan penetrates the plastic bag. 

How should I normally implement it? I would like to know which parameters or components to pay attention to.
