Hi,

I upgraded to Version 7 and I have noticed something strange in editor, whenever I select in play mode runtime inside editor the object of Obi Rope, it instantly reflects and rope does some movement. Like for example if an object is hanging by rope its oscillates a little up an down. Similarly I have also noticed that when scene is started the same object oscillates up and down a lot more than before (I kept the parameters same like in version 6), why change in behaviour? It oscillates for about 2 seconds whereas before it was just 0.1 second.

Hi,

I'm unable to get any visuals of the chain in New Obi Rope Chain Renderer in URP. Even the sample demo that came with the project only works with Built-In pipeline, it does not work in URP even I don't see any pink shader for the chain, when I upgrade its materials to URP I still don't see any chain, not even a pink error shader. Its just blank. I have tried everything including GPU Instancing. I'm on Android Platform for Quest 2. Using Unity 2023.2.19f.

Step to reproduce

Create a new URP Project (2023.2.19f)
Import OBI version 7
Open Chains Demo from OBI
(upgrade pink shaders to URP)

Hello.

Using Obi Softbody I could make the Obi Fluid particle to collide with a skinned mesh deformed by its bone transform.
I wonder if there is a way to implement fluid collision with such a deformed mesh without using Softbody.
Please tell me if there is a method.

Thanks.

So I have updated to Obi7,I used to modify skinned cloth constraints to 0 and set back to blueprint's data in runtime to reset cloth,
Just like the example:

var cloth = GetComponent<ObiSkinnedCloth>();

// get constraints stored in the actor:
var actorConstraints = cloth.GetConstraintsByType(Oni.ConstraintType.Skin)
as ObiConstraints<ObiSkinConstraintsBatch>;

// get runtime constraints in the solver:
var solverConstraints = cloth.solver.GetConstraintsByType(Oni.ConstraintType.Skin)
as ObiConstraints<ObiSkinConstraintsBatch>;

// there's only one skin constraint per particle,
// so particleIndex == constraintIndex,
// and there is only need for one skin constraints batch:
var actorSkinBatch = actorConstraints.batches[0];
var solverSkinBatch = solverConstraints.batches[0];

// get the offset of our first -and only- skin batch in the solver:
int offset = cloth.solverBatchOffsets[(int)Oni.ConstraintType.Skin][0];

// iterate over all active skin constraints in the batch,
// setting their properties:
for (int i = 0; i < actorSkinBatch.activeConstraintCount; ++i)
{
int index = i + offset;

// skin radius
solverSkinBatch.skinRadiiBackstop[index * 3] = 0.05f;

// backstop sphere radius
solverSkinBatch.skinRadiiBackstop[index * 3 + 1] = 0.1f;

// backstop sphere distance
solverSkinBatch.skinRadiiBackstop[index * 3 + 2] = 0;
}

So the problem is this method can only use in CPU backend,
Can anyone tell me with out this method, Is there an easy way to reset skinned cloth with GPU backend?

I'm on 2022.3.27f1. 

I added blueprint

I reset the layout

Re-import all

still no edit path. 


I got "Failed loading overlay Obi Path Editor" error message on console but forgot to take screenshot of it

It says in new documentation

Quote:ObiCursor.ChangeLength() no longer takes an absolute length as parameter, but a change in length.

Hi,

I am using obi rope version 7, I have one solver at the root and multiple ropes in hierarchy downwards. I need to freeze or pause the rope in some cases like its rendered but freezed and not moving even if its parent object is moving too. Is it possible to achieve that? Is it also possible to do it for only one rope explicitly even if one solver is controlling multiple ropes?

Also can I extract a mesh in editor and may be replace it with a rope at runtime to depict a freeze?

Hi, there are some things I wonder about. I use Unity 22.3.9, Obi 7 and default renderer.

1. When editing control points the camera controls become weird. If you middle click the camera jumps an odd distance and it's not possible to drag and move it like usual. Also the rotation is disabled. I have to turn off control points if I want to move the camera and it's really annoying. Is that how it's supposed to work?

2. Using chain renderer, the chain meshes only receives light from directional lights, not spot or point. I don't use directional lights so the chain is unlit. How do I make it work with spots point lights?

3. I want to export the finished chain as a FBX file, but Unitys FBX export tool does not work. Is there a way to do this?

I've just upgraded to Obi Fluid 7--removed the previous version before adding the new package.  I've got it running well in the Editor, but in an actual build (for Windows PC) the Fluid Mesh is not rendered.  Any suggestions?

Hi  I would need to call ChangeLength for ObiRod. We can do this for ObiRope but I need this feature in ObiRod is it possible ?
