Hi, I Want to make a rope swinging system in my game I already did this using  Hinge joints but the rope does not look good that way this is what I have right now Video of the current rope made with hinge joints

To make the rope look better I bought the Obi Rope asset and tried doing this: I added 2 Obi Particle Attachment components to the rope and assigned the player on the first one and gave the starting control point in the particle group and assigned an empty object on the other one and gave it the ending control point in the particle group what happened was that the player would be the object that the rope would be hanging from but I wanted it to be in reverse the empty object holding the rope from above and below it, the player after the player moved I wanted the rope to follow along with it is there any way to do this?

I get some errors compiling for Android target
Using Unity 2020.3.30f
See screenshot of Unity Console
   

Note: I am not using any Obi shaders/materials, only Standard shader with color.

Hi!
I'm currently developing a suturing simulator for medicine students, and I'm having big trouble finding a way to replicate this exercise in my app (https://www.youtube.com/watch?v=DIUy3jeM6sY). As you can see from this second video (https://www.youtube.com/watch?v=5ZXG9LiYFdc), even with self and surface-based collisions activated and using only distance fields for collisions, the rope passes through itself and objects, making creating a knot impossible. Do you have any suggestions to solve or "bypass" (IDK, maybe dynamically substituting the rope blueprint with a "baked knot" by hitting a controller button at the right time?) this problem?
In the attachment, you can find screenshots of the solver and rope parameters.
Thank you for your attention!

Hi,
Sorry for my bad english, it's not my first language.

I'm new to using obi rope and rod, so the solution is probably simple, but i can't figure it out despite looking at the video and reading the manual.

I'm tryinig to make a simple rope bridge, with a couple plank pin to two ropes. Before i use a static 3D model (see image model), but I would like to recreate those model with obi rope so they react to the player passing on them.
   

I wasn't sure if i should use robe or Rod so i try to set up both to see what would work the best (i don't need them to move much). In Red plank is the rope and in green the rod. Both use the same solver value, but i have 2 solver in my scene (one for each).I added a particule renderer on all the rope and rod and 2 particule attachement to pin the rope/rod to the plank on each side. The attachement are in static, but changing them to dynamic don't change anything to the result. They also have similar path with a little down curve. They also have a resolution of .5 thickness of 0.1

If they stay about as such, it would be fine for me, but when i press play...

   

they get all twisted in the middle and i don't understand what's causing this and with this happening when i just try to link a rope to 2 fix plank, i worry about what it will be when i try to add plank to this bridge.

Please help, i'm at a lost.

Hi, 

When I instantiate a prefab consisting of ropes (that then get reparented to ObiSolver object in OnEnable), the OnCollision seems to not catch any collision events with the targeted particle (beginning of rope) but when the prefab is already in the scene, OnCollision is detecting collision events with that particle. Its only with that particle, it seems to throw events with other particles along that rope when instantiated.

It working, this is with the prefab placed in the scene from the start:


When the prefab is instantiated, no collisions events detected from that particle:


OnCollision:

Say I want to make a physics bowl containing some fluid that you can stir. I would make a bowl model, and then create a bunch of box colliders roughly tracing the shape of he the bowl since Unity only supports convex colliders for rigidbody physics.

Obi doesn't have any problems with concave colliders, looks like the convex check box on the referenced mesh collider is just ignored by the obi collider that uses it. But I still can't have my concave bowl because Obi seems to require an enabled, non-trigger Unity collider component to work. That means any mesh collider on the bowl will also inevitably affect the regular rigidbody physics, and the rigidbody will always be forced to use a convex version of the mesh collider that obi uses.

Am I missing something or is there no way to have a concave rigidbody that interacts with obi particles?

Loading Obi Softbody into a new project warns of obsolete API.
A lot of console errors.
Running examples is possible (no breaking code) but none of the sample scenes work for me.

Getting a lot of errors of this when I run a sample scene:

Hello, I am developing a third person game with non-humanoid players and enemies/npc: insect-like and reptile-like characters with different body structures(they can have tails, antennas and other different kind of limbs/members which will be used for attacking/defending) and complex locomotion system(they can walk on walls or upside-down, can jump, moving objects will push them away etc).
What i mostly want to achieve is to make the characters behave like active ragdolls so that the limbs mentioned above and the rest of the body will not pass through objects, and also external objects forces which should include the other enemies who attack me(for example getting hit by a tail or by throwing a rock) should make the creature react to hits by moving and rotating the hitted part of the body or the entire body depending on the hit force. 
Also most of the animation will be made procedural using inverse kinematics.

Now i am not here to ask how to do it  but i want to know if obi rope/bone components is helpful for creating this kind of active ragdoll because browsing obi bone setup and other examples gave me the impression that it can make the tasks easier.

Environment: Win10, Unity 2022.1.0b4.2571, Obi FLuid 6.4 with Burst Solver, FluidKarmanVortex scene.
1. Warning of setting the velocity of a kinematic body. See the file of waring1.
2. Job access out range error. See the file of error1.
3. The particle advected by the fluid will disappear a few times after the scene started. The particles will quickly disappear after being emitted. See the image.

Hello!

Context:
I am relatively new to unity and very new to Obi Fluids. I am working on a VR project where I have an emitter for a sink that turns on if the player holds a cup under the sink. This part works fine, but because I want the particles to stay in the cup, I have set the lifespan to "infinity" for my sink emitter. This works fine when the water is in the cup, but because movement is very jumpy/sudden in VR, sometimes the particles will fly out of the cup and into the sink / on the floor.

Question:
Is there a way to make it so particles are killed (lifespan set to 0) if they touch the sink or floor (or any specific object) and still have an infinite life in the cup? The goal is to have an infinite life for the particles only while in the cup, and if the particles hit the sink or floor they are sent back to the emitter. This would mean I could theoretically fill up my cup, dump it down the sink and see the particles "drain", and fill my cup at the sink again.

Let me know if I can clarify anything. As mentioned, I'm relatively new to this, so I don't have any foundation work for this goal; I'm starting from scratch. I mostly want to know if it's possible and what I would need to do to make this happen (e.g. call a system or built in function that I am unaware of.)

Thanks!
