Hi, I tried to create a simple rope with hanging object. I works as expect on the test scene, but on my game scene its acting weirdly.
Obi Solver, Obi Rope, OniCollisionWorld are on prefab. On my test scene the prefab is already on the scene hierarchy, but on my main game scene the prefab is instantiated on runtime.

| Obi Wire with more tension than rope |

Is there a way to really tension the rope within the obi solver or anywhere to make the rope be closer to a bendable wire/rope? It currently has too much flex and bounce for what I need it for, and need it to be able to flex and have the gravity of a rope, but not so fluid. I am also not looking for it to be rigid like the rod, a good middle ground between these 2 is what I am looking for. I have tried turning the substeps up quite a bit, and this does not get rid of the fluid movement enough and make the rope rigid enough with more tension for my needs.
Thank you

Hello, I have some doubts regarding building a football net for my game.
The main one is presented on the title, does both plugins are necessary to build this?
Beyond that, what about performance (cause if these 2 plugins must be used together, maybe the performance overhead should be a concern here)?
And finally, how hard is to implement it for this particular use case (I'm not an expert programmer)?
My current project is just a penalty game for now, but the plan is to extend to other parts of the sport at some point. The ball is a rigidbody, using a standard sphere collider, with 0.22 scale and 0.43 of mass. The maximum speed of it is around 130 km/h for penalties. But this speed will be increased for free kicks (the most powerful shot recorded was fired at ~210km/h for instance). Additionally, I should add crowd and stadium model at some point, which means more stuff to be processed at runtime. The target platform is PC, but I would like to leave a conversion to mobile viable, if possible...
I would like to buy the/these asset(s) on this sale, Obi is expensive in my country thanks to the exchange, so I want to confirm that it will be a really useful for what I need...
It seems a very good asset by the way, I'm amazed by the results on the preview videos, congratulations!

| Obi rod or obi rope? |

Hello,
We are using Obi Rope & Rod objects to create worm-like creatures.
The Rods have been harder to setup, and we would be happy to have your feedback on the issues we encountered in order to choose whether we use them in our project, or just stick to Obi Ropes.
- When editing a path, the Rod seems to quickly add twists and distortions on the curves.
As you can see in the picture below, the wireframe of the rod shape suddenly rotates 180° in the middle, adding distortion to the mesh… this might be related to the varying thickness we applied to the different key points/particles ?
We do not seem to have this issue with Ropes, maybe as the particles are not oriented ?
- We cannot get the Rods to maintain their Rest shapes, in Play mode, they mostly seem to behave like Ropes (please see the attached video).
Is there any thing we could be missing in the way we build them ?
We followed the steps on your website, and made sure the “Keep Initial Shape” value is turned on in the BluePrint.

Thanks in advance,

| Rope cursor jittering from strange spot |
|

Hello,
I am trying to simulate the unrolling of a bobbin when a player moves the "bobbin" that the rope is attached to. I am planning to add more ropes to try and do a braiding simulation. I need each rope to have a cursor so that when they move around one another they wont stretch so much as to pass through one another.
I have a single rope set up and it is extruding properly in the beginning, but then begins to develop a kink at a spot that makes no sense (it could be the original length of the rope). I have played around with the cursor Mu and it seems to have no effect on this kink. Do you have any suggestions to make this more stable? Right now I am measuring the strain in the rope and if it is above 10% then I run the change length command. Overall, the rope is also quite jittery, which I would also like to try and reduce.
Here is a video of the defect.
And here is my bobbin controller script:
Code: using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Obi;
public class BobbinController : MonoBehaviour
{
public ObiRope rope;
public float speed = 1f;
Vector3 velocity;
Rigidbody rigidBody;
ObiRopeCursor cursor;
RuntimeRopeGenerator ropeGen;
//ObiSolver solver = FindObjectOfType<ObiSolver>();
float ropeLength;
// Start is called before the first frame update
void Start()
{
rigidBody = GetComponent<Rigidbody>();
cursor = rope.GetComponent<ObiRopeCursor>();
ropeLength = rope.restLength;
}
// Update is called once per frame
void Update()
{
Vector3 input = new Vector3(Input.GetAxisRaw("Horizontal"), 0, Input.GetAxisRaw("Vertical"));
Vector3 direction = input.normalized;
velocity = direction * speed;
float currentLength = rope.CalculateLength();
float restLength = rope.restLength;
float strain = currentLength/restLength;
if (strain > 1.1)
{
cursor.ChangeLength(rope.restLength + speed * Time.deltaTime);
}
else if (strain < 1)
{
cursor.ChangeLength(rope.restLength - speed * Time.deltaTime);
}
}
private void FixedUpdate()
{
rigidBody.position += velocity * Time.deltaTime;
}
Any help would be greatly appreciated.

| Set Cloth Properties with script |

Hello,
Im currently trying to create and assign a skinned cloth blueprint to some cloth parts i have in my scene.
I have succesfully managed to do this but im having some issues setting the cloth properties values with the script (skin backstop, backstopradius, radius).
Code: blueprint.inputMesh = mesh;
ObiSkinnedCloth obsc = childobject.AddComponent<ObiSkinnedCloth>() as ObiSkinnedCloth;
obsc.skinnedClothBlueprint = blueprint;
ObiSkinnedClothRenderer obscr = childobject.AddComponent<ObiSkinnedClothRenderer>() as ObiSkinnedClothRenderer;
I found this relevant topic: http://obi.virtualmethodstudio.com/forum...-2405.html
but i cant make it work.
So, how do i manage that?
thanks beforehand!
