Hello! I just recently bought some of the assets, looked through the docs and am experimenting a bit.

I'm trying to do achieve something like a procedural animation for hooking a static object, where the rope is thrown to do a whip like motion to loop around a cylinder for a few turns to get stuck. I've achieved a version of it by using a rope attached to a collider at it's end, and then using a spline to get the desired whip like motion. First I tried to attach a part of the end rope to the spline, but didn't look too good as the big momentum should be with the collider. Now I'm simply moving the collider with the spline as kinematic & then apply the spline velocity at the end and mark it dynamic. I'm all open to suggestions of how to do this animated physics differentley.

I've had some issues with gaps of my Particle Attatchment to the Unity Collider when I run the sequence. I moved from using a SplineAnimator to evaluating the spline myself in fixedUpdate. But it seems I still have to wait for a certain time before I can set the collider in motion. What is the intended way to set up this dependency?
I also seem to have a general issue that particles at the end of the rope are more sparse where I need them more for more defined collision around the cylinder compared to the slag of rope hanging from the hand where I could do with very sparse amount. Is there any way to distribute more particles at the end of rope or mitigate this?

Thanks for any insight or point to docs that I've missed.

Good morning,

i am creating a simulation where everytime the game gets loaded there is an example shape around some nails an elastic has to reach. 
the elastic is represented by a closed loop obirope. 

in the start method i call a function that sets the elastic global position based on the shape. Now i woul dlike to actually move 2 or 3 particles to create the shape and hook the nails i need to
private void Start()

{
    repetition = GameManager.Instance.GetCurrentRepetition();
    Debug.Log("repetition is : " + repetition);
    SetNailsAndElastic(repetition);

}

private void SetNailsAndElastic(int repetitionNumber)
{
    GameObject[] allNails = GameObject.FindGameObjectsWithTag("Nail");
    foreach (GameObject nail in allNails)
    {
        nail.GetComponent<Renderer>().material = defaultMaterial;
    }
    switch (repetitionNumber)
    {
        case 1:
            HighlightNails(new string[] { "nail_1_r1", "nail_c_r1" });
            Debug.Log("in rep1");
            elastic.transform.position = new Vector3(-2.17000008f, 0.810000002f, -10.4899998f);
            elastic.TeleportParticle(82, new Vector3(1, 3, 5));

            //elastic.blueprint.positions[82] =  new Vector3(1, 3, 5);

}

this is a small snippet of my code, and this is what i try to do to move that specific particle for example. 
The particle doesn't move though, even if the elastic takes the right position i wrote there

do you have any advice??

I'm using Obi Cloth 7.0.3, in Unity version 2022.3.51f1.

We have a system that automatically generates meshes and turns them into cloths. We've been troubleshooting issues with inconsistent cloth behaviour, and noticed some leaks. The messages don't seem to specify if they're memory leaks, handle leaks or some other kind of leak.

One of the leak logs. They're all related to line 256 of ObiNativeList, and all occur as a consequence of the solver running Initialize() as part of InsertBufferedActor():

Hi, if I have deformed a softbody using obi particle dragger, is there a way to avoid regaining its original shape once I leave the picker? 
Example use case: simulating mesh flipping without it retracting back automatically, etc.

Had some issues with the update from Obi Rope 6 -> 7 in a project that used Obi Rope 6.  Luckily it's a scratch project.

1.  I tried upgrading on top of the old version but saw script errors so I removed all Obi files and installed fresh instead.  Of course, I have scripts and prefabs that depend on the older Obi files, so all of those break in the process of installation.  Even after the other issues were patched below, my existing code runs into Index Of Of Range errors on trying to load my existing rope blueprints, so now I have to see if it's a code issue or a blueprint schema change issue.  [Edit: I see the forum update guide says you have to regen blueprints.  I'm creating them from code, see below.]

2.  The demo scenes use a resource script called FPSDisplay.  It does not use a namespace, so it conflicted with another script I already had called FPSDisplay.  This caused compilation errors and breaks the script references in scenes that used either one (my existing scenes, as well as your demo scenes.)  Even after I added a namespace to my existing FPSDisplay, the script references were broken, so I had to add a namespace to your file and re-add it to the demo scene objects.  I thought Unity demanded all assets used namespaces to avoid this sort of conflict.  [Edit:  Similar breakage on SlowmoToggler which does not have a namespace (I have no such script but your demo scene had a broken link to it and Unity couldn't find it until I added one).]

3.  Many of your demo scenes use a built-in diffuse material for many objects.  Please define your own material for these objects, so that when I update all materials to URP these objects don't remain pink.

4.  There is no longer a type for ObiFixedUpdater.  I had a script that expected this type to force a regeneration of ropes (as I would deactivate and reactivate ropes in proximity to the player).  The CHANGELOG says all ObiUpdater types have been removed.  No guidance on what to do about scripts that referenced them.

Good morning,

I created a code to grasp an obiRope. It is not the first time i use it and untill now it worked fine, I have anotehr simulation that uses the same logic and I have no issues. 
Now when the simulation starts the obiActor is not loaded in the script, even if i associated the code to it or passed it as a reference. 
The grasping works but badly, and I think it is because of this issue.  
the code:
```
using UnityEngine;
using Obi;
using System.Collections.Generic;

[RequireComponent(typeof(ObiActor))]
public class DistanceAnchor : MonoBehaviour
{
    public ObiActor actor;
    public ObiParticleAttachment attachment;
    public Transform anchor;
    public float anchorRadius = 0.5f;
    private ForcepsControl forcepsControl;

    private int groupIndex;
    private bool isGrasping;
    public bool IsGrasping
    {
        get { return isGrasping; }
    }
   

    void Awake()
    {
        actor = GetComponent<ObiActor>();
        forcepsControl = FindObjectOfType<ForcepsControl>();
        if (forcepsControl != null)
        {
            forcepsControl.OnRestPositionReached += CheckAndAnchorParticles;
            forcepsControl.OnReleasePositionReached += Release;
        }
    }



    void CheckAndAnchorParticles()
    {
        if (!actor.isLoaded)
        {
            Debug.LogError("Actor is not loaded");
            return;
        }

        for (int i = 0; i < actor.solverIndices.count; ++i)
        {
            int solverIndex = actor.solverIndices[i];
            float distance = Vector3.Distance(actor.GetParticlePosition(solverIndex), anchor.position);
            Debug.Log($"Distance to Anchor: {distance}, Grasping State: {isGrasping}");
            if (distance < anchorRadius && !isGrasping)
            {
                Grasp(actor, i);
            }
        }
    }



    private void Grasp(ObiActor actor, int index)
    {
        if (attachment != null)
        {
            Destroy(attachment);
        }

        attachment = actor.gameObject.AddComponent<ObiParticleAttachment>();
        attachment.target = anchor; // Attach to the anchor
        attachment.particleGroup = actor.blueprint.AppendNewParticleGroup("GraspedParticles");
        groupIndex = actor.blueprint.groups.Count - 1; // Ensure it's the last added group
        attachment.particleGroup.particleIndices = new List<int> { index };
        attachment.compliance = 0;
        attachment.attachmentType = ObiParticleAttachment.AttachmentType.Static;
        isGrasping = true;

        actor.solver.RemoveActor(actor); // Refresh the actor in the solver
        actor.solver.AddActor(actor);
    }
    private void Release()
    {
        if (attachment != null)
        {
           
            Destroy(attachment);
            actor.blueprint.RemoveParticleGroupAt(groupIndex);
            actor.solver.RemoveActor(actor); // Refresh the actor in the solver
            actor.solver.AddActor(actor);

            isGrasping = false;
        }
    }


    void OnDestroy()
    {
        if (forcepsControl != null)
        {
            forcepsControl.OnRestPositionReached -= CheckAndAnchorParticles;
            forcepsControl.OnReleasePositionReached -= Release;
        }

        // Ensure to release any grasped particles
        Release();

        // Additional cleanup if needed
        if (attachment != null)
        {
            Destroy(attachment);
            attachment = null;
        }
    }
}
```

the error: 

```

Hello,

I have a logic where I need to change the ropes material during runtime. I tried setting obiRopeExtrudedRenderer.material = new Material(copyFrom); it looks like the material is changed in the component itself but it doesn't effect the renderer. I assume this is cached on start. Is there a way to do this?

Thanks

Good morning,
I’m encountering a strange issue with grasping a closed-loop ObiRope using two tools. My goal is to grasp different points on the rope with each tool, without using constraints.
The Problem:

• If I grasp the rope with the left tool first and then with the right tool, everything works as expected. Both tools hold their grasping points correctly.
  
• However, if I grasp the rope with the right tool first and then with the left tool, the following happens:
  • The right tool keeps its constraint but the grasped particle shifts to a position far away from the intended grasping point, while still visually connected to the tip of the tool.
    
  • The rope responds to tool movements but maintains this unnatural offset for the right tool.
    
• The issue only happens when the right tool is the second to grasp, and it occurs inconsistently.
  

• Confirming the attachments are created dynamically at runtime without pre-existing constraints.
  
• Checking that particle indices are updated correctly during grasping.
  
• Ensuring the tools have unique attachment components.
  

• The left tool is holding the rope correctly.
  
• The right tool exhibits the described offset issue when grasping second.
  

Helloo, this occurred quite a while back for me and I've been able to work around it but I thought I might as well see if it can be fixed!

as you can see (though they are quite small) the handles and particle sphere gizmos that appear while in the rope blueprint path editor were at some point shrunk by me... and I'm not sure how to unshrink them as the regular 3D gizmo size slider doesn't seem to affect them. 

Thanks!

Hey, I would like to, in my VR app, make a barrier belt, like in cinemas at the box office or airports to cordon off aisles.







This is my script that I made along the lines of a similar script I found in examples (grapling hook) (I cannot post it in the message because of error)
https://pastebin.com/sC54e9fh





I noticed three main problems:


1.  A visual bug, as if the UV scale increases indefinitely. I have no idea what this could be. (video in attachments)

































2. Particles are not forming where the Rope length has been increased. You can see better in the screenshot what I mean.











3. When I move an object quickly in the editor, the Obi Particle Attachment doesn't seem to keep up. Does this problem only occur in the editor? Is there any way to improve it? (video in attachments)











4. When I select the ‘Roll-Out Rope’ object on the hierarchy then I get a spam on the console:
