Hi, is there any way to limit active rope length? I can acces the restlength but the rope can get longer than it. 
So is there any way that i can control how long the rope can get (from code) ?
I can see how long it gets from rope.CalculateLength, but i want to control it as well.

Hi There,

I am working on developing a game intended for use on low end laptops (https://www.stonegroup.co.uk/stone-produ...-business/)- something you'd typically find in Universities, colleges etc. I understand fluid simulation is intensive, but how optimised can Obi Fluid be? 

An example of the type of project I am looking to make involves pouring liquid A from one container to another containing another liquid B, possibly making use of the "chemical reaction" aspect and changing the resulting liquid to a mixture AB: changing colour, viscosity etc.. 
Is this something that is possible on lower end hard ware in a 3D environment, or is the chemical reaction something that is mainly possible in the 2.5D style plane shown in the demo video as it would be quite intensive?

Just checking as I have limited funds for the project.

Hi, I've imported both Obi fluid and Obi softbody and I got this error in my console

DllNotFoundException: libOni assembly:<unknown assembly> type:<unknown type> membernull)
Obi.OniBackend.CreateSolver (Obi.ObiSolver solver, System.Int32 capacity) (at Assets/Obi/Scripts/Common/Backends/Oni/OniBackend.cs:17)

Obi.ObiActor.AddToSolver () (at Assets/Obi/Scripts/Common/Actors/ObiActor.cs:348)
Obi.ObiActor.OnEnable () (at Assets/Obi/Scripts/Common/Actors/ObiActor.cs:323)

Not sure how to phrase it, some images to explain what I'm running into.

I've created a relatively simple shape:
   

Created a blueprint:
   

But no matter what I do, even copying the values you've added to your objects when I run the game, it just falls flat (next to your example ball):
   

Why doesn't it stay more solid? What values should I be looking at?

I have an Obi Rope attached to a rigidbody. The rope follows the rigidbody no matter the distance. I want the rope to hang, and have the object there hanging from the rope.

Searches through the documentation and this forum keep referring to "stretching settings". I cannot find these settings.

Increasing substeps also does not fix this, and also causes massive frame drops.

Please help.

Hello,
When I put an ObiBone component on this snake model (21 bones), most of the bones are twisted by a certain degree, giving weird behavior (see white lines).
What's strange is that it wasn't the case before, and that all the bones have 0 degrees rotation in all axes in the base pose, and at start... Then the Animator starts a "Rolled" static animation which just curls the snake around the branch.
Can't figure out what is causing this.

   
   

Otherwise it's working very well, I get snake like movement when I adjust the Collision Materials.

Hope you can help, it's for a good cause (snake phobia exposition therapy).

I am trying to use Obi rope in Unity 2021.3.0f1 ( MacBook Pro (13-inch, M1, 2020) chip Apple M1 )

its showing the following errors -- >

I also tried following solution -->
    The dll library it cannot find (because it’s not compatible with the M1 architecture) is just a fallback in case you haven’t installed the required Burst  packages. Moreover, this fallback library is deprecated in will be removed in Obi 7.Make sure you’ve installed the Burst dependencies as per the manual:

Tried the following setup -->
     [color=rgba(var(--sk_highlight,18,100,163),1)]http://obi.virtualmethodstudio.com/manual/6.3/backends.html#burst[/color]

In the above setup I am not getting the option of
    JOBS -> Leaks detection -> Off

Hi, I would like to ask if you can consider creating a tutorial on this, I am specifically interested in wheel mesh that will use the obi softbody on low poly  wheel mesh, car/vehicle will use normal unity controller type. It is only the wheels that I would like to behave like softbody. Can I ask you to advise or guide me on this request please?

I've only able to find example for adding pin constraint, and before I do anything dumb myself, I'd like to get an example for adding distance constraint through script.

Is it as simple as adding two indices for the pair of particles in the new distance constraint to the batch array and mark the constraint type as dirty?

When I look into the Tear() method it looks like I also need to apply some properties to the new constraint, but there seem to be other things going on which I'm not sure if it's only for the reconstruction after the tearing operation...

I opened an empty 3D project and imported packages Burst, Collections, Mathematics then Obi Fluid 6.4 as suggested.
The sample scenes run without issue in Game mode, but fails to build. I get the following Error: 

Shader error in 'Obi/URP/Particles': Couldn't open include file 'Packages/com.unity.render-pipelines.universal/ShaderLibrary/Core.hlsl'. at Assets/Obi/Resources/ObiMaterials/URP/ObiLightingURP.cginc(3)

I included the whole log in the attachment. The specific scene I am trying to build is MultiPhaseFluidBuoyancy, although all other scenes are having similar build problems.

Unity Version 2021.3.7f1
Obi Version 6.4
Burst 1.6.6
Collections 1.3.1
Mathematics 1.2.6
