Hello,

I am working on a game in Unity where I want to add pin constraints all the way down the Obi Rope at runtime. Every unit of the rope should be covered with a constraint. The idea is that I'm attaching selectable colliders that can be "grabbed" by the player and then swung on.

I copied almost exactly the code from the "adding/removing constraints" page on the website here: http://obi.virtualmethodstudio.com/tutor...aints.html
Unity didn't like a few of the casts so I modified it slightly, but it's more or less the same.

Here's my current script:

Perhaps I'm doing something wrong but every time the FPS is below 60 the rope starts twitching.

Below is the example.

I've added some post processing to the camera to lower the fps.

Are there any general guidlines or tips to follow in order to reduce Obi Rope’s CPU footprint? Obi currently more than halves my framerate when simulating and I’m looking to get it back down to acceptable VR speed. It seems like most of it comes from updating obi colliders (ObiSolver.FixedUpdate.UpdateColliders is around 30% of frame’s total time.) I’ve been pretty fast and loose with adding obi colliders around since a lot of the game is very up close to the ObiRope cables and I wanted them to interact well with things inside the VR space. Do I need to be more sparing with these?

The other large chunk comes from rendering with ObiSolver.LateUpdate…ObiRopeThichRenderMode.Update being another 25% of my frame’s time. Smoothing seems like the main culprit (drops to aroung 7% when changing smoothing from max 3 down to 0), but decreasing it doesn’t have pleasing results. Should I be using higher cable resolution or some other method to achieve less angular cables instead?

It’s also a huge multiplier on the physics update, increasing it by at least 2 times when the solver is enabled, sometimes more (running on a timestep of .01 with the default 6 solver iterations). Is this just part of the deal when it comes to running this solver, or does it seem like that should be reducable somehow as well?

The scene in question has around 20 cables with an average of around 15 particles each, 4 pins constraints each, hierarchical tethers, and full smoothing/rendering. The solver is set to skip skin, volume, stitch, and density, but does everything else on Sequential settings with 5 iterations. Solver reports that it’s only using 466 particles total, which seems well within a reasonable range, hence my looking elsewhere for spots to improve performance.

Has anyone used obi fluid to make something similar to a fine powder, like baking soda or flour?

Hello! Thank you for the wonderful asset
Can you help me with the problem of creating an emitter in the code? The object is created on the scene, all obi objects are configured, but the render does not work.



Here is my code:


public void Init()

        {

            GameObject emitterObject = new GameObject("emitter",

                typeof(ObiEmitter),

                typeof(ObiParticleRenderer));



            emitterObject.transform.position = gameObject.transform.position;

            emitterObject.transform.parent = gameObject.transform;



            _emitter = emitterObject.GetComponent<ObiEmitter>();

            _emitter.Solver = GameControllerObjects.Instance.ObiSolver;

            _emitter.NumParticles = 1000;

            _emitter.emissionMethod = ObiEmitter.EmissionMethod.STREAM;

            _emitter.speed = ((Liquid)VRAObject.Type).Speed;

            _emitter.lifespan = ((Liquid)VRAObject.Type).Lifespan;

            _emitter.randomVelocity = ((Liquid)VRAObject.Type).RandomVeloncity;

            _emitter.EmitterMaterial = GameControllerObjects.Instance.ObiEmitterMaterial;



            Color newCol = new Color();

            string htmlValue = "#" + ((Liquid)VRAObject.Type).ParticleColor;

            ObiParticleRenderer particleRenderer = emitterObject.GetComponent<ObiParticleRenderer>();

            if (ColorUtility.TryParseHtmlString(htmlValue, out newCol))

                particleRenderer.particleColor = newCol;

            particleRenderer.radiusScale = ((Liquid) VRAObject.Type).RadiusScale;

            GameControllerObjects.Instance.ObiFluidRenderer.particleRenderers.Add(particleRenderer);



            StartCoroutine(OnFinish());


        }

IEnumerator OnFinish()

        {

            yield return _emitter.StartCoroutine(_emitter.GeneratePhysicRepresentationForMesh());

            _emitter.AddToSolver(null);
        }


Also I have Exeption!
NullReferenceException: Object reference not set to an instance of an object

Thank you!

Hi!
I saw video on the youtube https://www.youtube.com/watch?v=sc6kq1TV8Ek. I am doing everything the same, but have a problem. When I activated animation in Unity, shorts are torn.
The same problem I see in DAZ when turn animation on.
When I change poses in DAZ also appear holes on clothes, but in 1 sec everything goes to normal and clothes puts on correctly.
I spent many hours in solving of this problem, but nothing.
Daz 4.10
Unity 201.3.1f1
Genesis 8

So, i was  searching for alternative way for clothing and found your asset.
Questions:
1. Does it works with Daz3d genesis 8 models and clothing?
2. Will it solve my problems with holes?

Dear sir,

May I know if the plugin will work with Oculus rift and an imported 3D model with interaction like pouring water?

Best,

Mike

My project got crashed when i update the latest Obi Cloth version. Please help me fix this problem!

I just want to make the black line of this object to be teared only. I have tried to set the per-particle tear resistance but when the cut region was pretty bad. Are there any solution?

I want to make a link between two Obi objects with rope but when i pull the rope to the left, the rope seems to jump out of the Obi Cloth. I need some help !
Here is an example: https://www.youtube.com/watch?v=hlK-j3rf...e=youtu.be
