I am using parts of grappling hook to create rope.
********************************
How do you make sure the particles are turned on. The obi Solver shows 0 particles.
********************************
When you are moving the end of rope, how do you FREEZE start/end prefab. They tend to juggle around.
Is there a script that forces the object to follow the camera?
********************************
What is the best way to prevent wires from clipping through walls.
what about setting the obi collider thickness to 0.1?

How do you prevent 2 ropes from clipping inside of each other.
The way it works, the point where the hoses cross, they sit inside of each other.
We are looking to have 2 fire hoses and 1 hose sits ON TOP of the other.

Trying to add a pin constraint and it will not allow me to add an object to the Pinned To: Parameter... it acts like nothing is in the scene at all...
I have created a cube and added the Rigid Body to it

I am having problems with grabbing rope, I copied the ball and chain.
I added a cube, attached the obi handle and it does not work.
Do I need to add the canvas with the words??

| Changing fluid emitter scale |

Hello,
I am modifying the faucet scene for VR and have a problem with the scale of the little fluid spheres that make up the simulation. When I view the scene in VR its really huge, so I am wanting to scale it all down. When I attempt to scale down the radius of the Obi particle renderer, the whole simulation fluid simulation does not look right, as if there is space between the particles. The default scale is set to 1.5, and anything below 1 looks terrible. Any help would be greatly appreciated.
Thanks

| ObiRope 3.2 Collision Position |

These are changes I made to determine where a Rope particle hit a Unity Collider in 3.2.
If someone has better solution please chime in!
Code: void Solver_OnCollision(object sender, Obi.ObiSolver.ObiCollisionEventArgs e)
{
foreach (Oni.Contact contact in e.contacts)
{
if (contact.distance < 0.01)
{
//Collider collider = solver.colliderGroup.colliders[contact.other]; **Obi 3.1
Collider collider = ObiCollider.idToCollider[contact.other] as Collider;
ObiSolver.ParticleInActor pa = solver.particleToActor[contact.particle];
To get ObiRope = pa.actor
To get index of Particle = pa.indexInActor,
To get collision point of Collider = collider.transform.InverseTransformPoint(contact.point));
(I use the above to Pin particle to object that was collided with)
To get ObiCollider = collider.gameObject.GetComponent<ObiCollider>();
*EDIT* Just noticed that niZmo's code works for 3.2 as well. You can find a complete solution here: ObiRope 3.2+ and VRTK 3.3.0 alpha+

Sorry to bother you with my fantasy, but is there any chance of this turning into an addon(paid or otherwise) for Blender?
ObiCloth is so much faster than the cloth sim in Blender, and better quality in many ways. I would buy ObiCloth again if I could use it in Blender.

| Save Rope State |

Has anyone been able to successfully save the state of a rope and load it correctly? I was told to pull the position and velocity arrays and serialize those and then set them again and push the data but that doesn't seem to work - the rope goes crazy at the start.
I would love to see an example of saving rope state that also takes into account any potential lengthening from a rope cursor.
Thanks!

| How to use with OVR camera |

Hi there,
I'm just getting started with Fluid and I have a few questions:
1. If there's a special relationship between rendering and a camera a scene, can you help me understand how this relationship works? I've placed an OVRCameraRig (using Oculus) in the Obi Sample Scene > FluidMill and I'm not seeing any particles being rendered. If I disable the OVRCameraRig and use the default camera, I can see the particles.
2. Can someone provide a more detailed explanation of "Simulate in Local Space" and what the alternatives are?
3. If I place my OVRCameraRig in a brand new scene, I can see particle imposters.
Hopefully this these are some simple noob questions. Looking for any tips/tricks that might help me work with ObuFluid in VR.
-Mike
