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.

Hi ,

  We have been using obi rope in our game for our hoses , we been experiencing two issues.

 1. the Obi rope goes through meshes , we been trying everything but in terms of collision the obirope allways go though the mesh once the tension in the rope passes a certain treshold.
 2. Crashes , they happen randomly through out the game.

If I want to view a fluid like Honey but after a set amount of time - after the corroutine turn the game object to "Active" the fluid will not render out. I can see it if I select "Render Particles"

Hi!
Thank you for great asset!

I'm making snake (from your awesome rope). By adding force to pinned rigidbody to first vertex.

But I faced with problem - very high friction on edges. When the snake under 90 angle to surface.
Do you you know any possible way to "fix" it? to minimize friction when rope under 90 angle to surface.

Hello,

We are considering a specific game's project and are looking for a 2D fluid simulator in Unity – obviously Obi Fluid seems the best ready-made solution.
Before jumping into it however, I have a few questions, I'd be glad if you could answer them:

1) The Obi solver manual states that "2D mode is usually coupled with the use of 2D colliders". Just to make sure, are you here talking about Physics2D colliders (BoxCollider2D, CircleCollider2D, etc.) as well as 2D rigidbodies? Indeed, performance will matter a lot to us, therefore using Unity's native 2D physics engine seems necessary.

2) Is solving buoyancy computational heavy? More precisely, is having a dozen of 2D rigidbodies (each with a CircleCollider2D collider) affected by buoyancy in a moving fluid, adds a lot of stress on the CPU as compared to, for instance, having just the moving fluid with the same amount of particles and same static colliders (for the 'environment' – tank, etc – containing particles)?

3) I read that emitters are either Disk, Edge, or Sphere. I guess they can be rotated in any axis so they are 3D-space emitters. So, in 2D mode, are the fluid particles computed in 3D space, even if the physics simulation is solved in XY axes only? If so, do their relative Z positions affect anything?

4) Are some simulation processes done in parallel threads or is everything computed in the main thread?

Thanks for reading, answers will definitely help!


PS: I believe that a self-executable demo of Obi Fluid, with both 2D and 3D modes, displayed framerate, interactive particle emitters, and a few objects that can be thrown and moved in the fluid with the mouse, would definitely help people to know what to expect when purchasing your product. (I know it would for us.)

I created custom class from ObiExternalForce, added my solver. But it does not work. Do you have any idea how to add external force to particular particles?

My question is about restart the rope simulation at runtime. I'm trying to restart the rope to its initial state (pooled particles count, path, used particles, etc.) at runtime.
Is there a method or way to restart the simulation via script?

Hi
I loved obi rope version 3.2 because I could use obi rope but new version 3.3 , when I press play button my ropes didnot work.I try to delete obi rope after that again import obi rope.It did not work + libOni.dll was crashed and now newest version 3.3.1 , when I press ,unity is crashing. By the way ( before 3.3.1 version)
ElectricalWires scene.When I press play button ropes does not wait holding and drag the wall ( like Tear is 0 )

How can use old version ? do you have download link ? I does not see any link
