I'm trying to make a belt with Obi Rope. I created a cross section that is flat and the resulting "belt" looks OK. I created a handle on the belt and parented it to a buckle. I want to be able to turn the buckle so that the belt also turns so that I can see the underside of the belt. When I do this though it looks like the part of the belt closest to the buckle turns but not the entire belt. I've also tried to pin multiple particles together to an obi collider but the results are similar.

Is this possible with Obi Rope? Am I missing a setting somewhere? Do I need something like Obi Cloth because the belt is more like a surface than a spline?

Thanks.

I'm using Unity 2017.3.1.f1.

In searching for this error, I see it was mentioned in the Obi Rope forum in late January. I checked the suggested solution and it appears that they are as they should be:

"Obi/Resources/ObiMaterials/ParticleShader.shader, line 20 should look like this:
#pragma multi_compile_fwdbase nolightmap"

The error follows:

Shader error in 'Obi/Particles': invalid subscript '_ShadowCoord' at line 82 (on d3d11)

Here's my current code to change the pinconstraints during runtime:

Unity will freeze when obifluid comes into contact with a moving gameobject - It only started to do this recently.
Any thoughts?

Hello there!

I'm trying to synchronize my rope in different clients by using PUN. Is there any simpler way to do that, except tracing every particle of rope?

Can Obi fluid particles be affected by obi wind or unity's windzone?

I load "FaucetAndBucket" scene and added 'Obi Ambient Force Zone', 'Obi Spherical Force Zone', and unity3d's windzone
near falling water particles. But obi fluid does not react on any wind elements..
(Of course I added my fluid solver to Obi force zones.)

Does Obi wind only effect on Obi cloth?

Thanks for reading.

Hello,

I'm trying to use the OBI to simulate the artery and aneurysm, and facing a problem that really hard to solve, hope if anyone can help me out.
What I'm trying to do is aneurysm clipping, use the clip on the aneurysm and it will deform when I clip it, the old way I'm doing it by direct moving the vertex in vertex shader, which works but not realistic enough. So I bought OBI cloth and trying to use physic to simulate this. The picture below shows how old way works.





Here is the problems I encountered: 
1) when I set up a obi version soft body, its too soft I have to increase iteration and add a bunch of constrains to make it looks real, which kills the performance. I'm using a 400 vertex mesh as particle base and use a 1300 vertex mesh as proxy. Is there any solution which can find a balance between visual and performance?

2) when I add some obi collider on the clip is not working, my clip is moved by Unity physic, and I have a hierarchy of rigidbody and fixed joint on it to work with clipholder. Any idea how to set up the obi collider to work with unity physic joint and rigidbody?

3) I'm trying to use two obi colliders(move by transform) to squeeze this soft body, it works when the collider is big enough, if the collider is the same size of the clip(which is small) soft body just go through the collider when I try to clip it. Any idea how to improve the collision detection with small colliders?

4) When I trying to make the soft body more rigid and looks real when I touch it, it seems hard to deform as I expected. When I trying to make it deform realistic, I have to make it very soft, which looks too soft when I touch it. It seems have a paradox between these two situations. Any idea how to solve this?

It will be great appreciated if anyone can help me solve this out!

I've created a system with four Obi Rope cables and a hook for a crane simulation.
When I change the length of the rope, each time a particle is added or removed the rope makes a jump.
See video: 

I'm using this code to change the length of the cables:

ive added an emitter and it emits particles , but the particles arent getting affecting by gravity for some reason they are just stuck where they got emitted 

please help

Is it possible to create the facuet and bucket scene but stop the water from falling through the buckets?
Anytime the cups are moved to quickly the water falls through the walls and bottom of the bucket. I need to hold water in a bucket but take care for water flying out of the bucket if the user gets....to excited.
My only idea is to put a invisible lid on the bucket to help it from pouring out until time, and destroying particles that fly out, and recreating them when they are destroyed.

I read in another post about using distance fields for improved performance???
When I try and create a distance field on the bucket (I also click the generate button on the df). I place it on the bucket but the water falls straight through. I can recreate the test environment and get that working just fine.
