Hi

I recently found that a memory leak in my scene stops if I disable the Obi solver.
I intend to try to reproduce this in a new smaller scene later, to do a better report, but for now I would like your opinion about this.

I'm using the last Obi version, in the last Unity 2019.4.22, and Windows 7 (64 bit).
My scene has 3 Obi clothes, each near an Obi Spherical Force (to simulate wind), and also around 20 gameobjects with Obi colliders and Obi rigidbodies (all of them Non Kinematic to particles).
I also have the Obi rope an Obi softbody assets in the project, but haven't added any of those elements yet.

The solver is configured like this:
   

The Obi force is like this: (if I disable the gameobjects with these forces the leak still happens, so I don't think they are related)
   

The leak happens in the editor and in PC builds, and you could say that it "eats" 1GB of ram in something like 200 seconds, so the application ends crashing after some time.

Other problem that I have seen, that I don't know if is related to the leak, is that if I have the solver enabled, but disable the 3 Obi clothes (that are children of the Obi solver object), then I start getting errors like these:
   

This is for some of the objects that have Obi colliders and Obi rigidbodies.
If you have an Obi solver maybe you need to have at least some Obi particles in the scene?

Hello,

Demo scene work fine but after I connect VR headset the fluid is not visible anymore.

Any help?

Best Regards,
Damian

The fluid that I designed is in a container which I move from left to right and up to down, when moving it up to down it tends to bounce and I want to avoid this since it is not realistic for my simulation, I already played with several parameters but they have not worked for me

Hi there,

I got some errors on the obi rope. How do I fix this? 
Thank you.

I want to click on my rope, from any length or side, by using RayCast.

Can I not use RayCast to interact with my rope? 

Hi there, I need to make a lot of washing machine animation in Unity, where the drum of the machine is spinning and the clothes move along with it and the water splashes all over. I'm wondering if obiCloth and obiFluid would be capable of doing that in such a small space at a medium speed. I've tried using Unity's cloth component, but no success. Could obiCloth handle something like this? 
Thanks

When modifying blueprints I am seeing many sub assets created (these do not correspond to points in I'm editing). While editing I'm also experiencing very long waits as the assets are processed, presumably as it created dozens of those particle group sub objects.

Really killin' my vibe at the moment.

Hello!

I have two questions about phases.

1. Is there a way to get a phase of an ObiActor? I know I can set one via SetPhase() and I think I can get a phase of a ObiCollider, but what about softbodies?

2. Can I adjust phases like physics collision layers in Unity? Here's why do I need this:

• I need my softbody player to roll through the level, so I apply torque.
  
• I need the player to push other similar sized softbody opponents like they're nothing, like a golf ball pushes table tennis balls. But as I apply torque, instead of pushing, player climbs over them. Setting all frictions to zero doesn't help. Reducing opponents masses makes things worse.
  
• So I've attached a sphere with ObiCollider to my player.transform as a child and got it player's phase. Now the sphere does the pushing, but I need to prevent player from interacting with the opponents. But I need opponents to be able to interact with each other.
  

Hi,

I'm investigating Obi Fluid as a way to create a solid/liquid system in my game.  Think melting a metal ingot and then having it re-solidify, possibly into multiple different pieces.
The property diffusion example in this video is pretty close to the effect I'm after (at 0:50s).


It seems like Obi can do the melting part easily, I'm just not sure about the re-solidification part.
Do you have any ideas on how one can use Obi can do this?

More specifically, I'm wondering if this kind of "permanent" fluid type system is supported by Obi e.g. like still water in a cup with "no particle lifetime" or a way to make it seem like there is no particle lifetime? 
Most videos focus on streams of fluids rather than still bodies. 
I'm after an effect where the player can smelt some discrete units of ore (e.g. 10 sphere rigid bodies) and they turn into a blobby melted mass which can be aggregated into one object (1 mesh with 10 times the volume of a single ore unit) and vice versa.

How can Obi emulate discrete objects in this way, i.e. preserving a physical quantity?

(sorry for the word vomit)
