Hello, 

This is my first post. I'am very beginner of using Unity and Obi rope. 
Now I'm trying to simulate the winding hard rope to the coil, which is rotating and slightly moving to right. End of rope is fixed to the edge of the coil. I create rope with Obi rope and set Obi Rope Cursor to extract/retract the rope.

But when coil starts rotating, rope pass through the coil and it does not wind around the coil. I set Rigidbody to the coil and it has enough mass. I have set Obi Collider both on coil and rope. 
I tried to solve this with changing iteration in Obi solver, but it didn't help. 

I read the following thread. On this thread, there is a youtube movie and it is similar to what I'd like to realize.

I'd appreciate any advice!

Thank you

Hi,

I have tried to mimic obi rope videos below to test behaviour of Surface Based Collision enabled ropes.

It has stutter/jitter issues. I am sharing the test video and also the test unity project itself.

Have a nice day!

In obi rope, ropes can collide with each other properly. But is there a way to detect that collision? For example, if a rope is not colliding with any other rope, I will make its color green; otherwise, its color will be red.

So in the docs it says that Filo cannot be used for free cable simulation. And then I've seen you post that the requirement is that you have to have objects connected to both ends of the rope. It seems to me then that you could have just two free (dynamic) rigid bodies with a cable linking them, is that possible? It seems like maybe not because in all of your examples, there's at least one static object. Is this a requirement or was that just happen stance? 

You also linked a paper in one of these threads that demonstrated a bow made from cables where it appeared as though the bow was a dynamic object. Would it be possible to make something like this possible with Filo? 

Thanks so much for any illumination!

Hi all,
I'm currently looking for a solution to use the Obi Rope pulling an articulation body's object 
I tried with a RigidBody and it went well, however, the articulation object didn't react to the rope
Thank you for all your help

For the app I'm developing I need to scale the simulation down to 5mm maybe even less than that, as I have some liquid coming out of a narrow tube. Is this possible, or is obi fluid not supposed to scale that low?

Using the example I added gizoms to debug some weird behavior I was seeing;

Code;

Do I need to install a previous release to work with my unity version?
The package I installed from the store a few days ago, the fluid renderer is not showing anything on the camera view, only through the particle renderer in scene view.
I'm using URP.

I have been making a VR bridge construction game and have been using the Obi Rope package to do cables for my bridges. An ongoing problem I have had is that there always seems to be a little slack in the cables when I run the simulation. 

Here is a video for context.

You can see the road of the bridge turns red meaning it is holding a great deal of its own weight rather than the cables.

My goal is to have the cables be stiff when bearing weight and not let the rest of the bridge sag.

Here is an example from a game that I have taken a lot of inspiration from.

 I have tried several things such as manipulating the blueprints resolution, the number of solver steps on the obi solver (to the point of very low fps) and incorporating a slight reduction in the stretching compliance. The last one was the most successful but not quite what I want. Is there a better way to reduce or get rid of the slack in the cables? Thanks.

Hi,
When I try to generate and edit a softbody surface blueprint by following the procedure explained here, obi seems to fail to generate valid data for the softbody surface blueprint.
I feed my mesh to a newly created blueprint and  hit generate. Right after the generation, nothing happens but when I hit edit button, I get an error as bellow.
