Hi,

As the title says, I'm attemping to use a 'locally-simulated' ObiSolver parented to a Rigidbody with it's interpolation set to 'Interpolate'.

Despite smooth Rigidbody motion, the various ObiCloth's (which are children of the ObiSolver), begin to jump / stutter sporadically as the Rigidbody picks up even a small amount of speed.

In my scene, the camera Lerps towards the RB. And the motion of the RB appears smooth both in Game and Scene view. But the motion of the various ObiCloth objects remains 'stuttery' in both views.

When interopolation of the RB is set to 'none', everything is smooth! Or at least when it stutters, it stutters in tandem with the parent RB. (However I still need interoplation for other reasons, so unfortuantely this is not a fix).

What I've tried:
Enabling interoploation on the ObiSolver itself actually appears to make the problem slightly *worse*.

I tried moving the ObiSolver directly onto the RB, rather than as a child. Unfortunately this made no difference.

Changing simulation order to 'LateUpdate' makes a big difference, although with still a tiny amount of stuttering. However, ideally I'd use FixedUpdate. -- As the documentation describes, LateUpdate is great for scenes which update object transform's outside of the physics loop. However, this is not the case for me, everything is driven via physics & FixedUpdate. Which is why I'm a little puzzled...

I'm using ObiCloth 3.5 with unity 2018.2.5f1.

My ObiSolver looks like so:


Any help on this would be greatly apprecaited.

Thanks in advance.

- Just to add, I've been super happy with ObiCloth 3.5, the enhancements to local solvers have benefited my project *greatly*, and makes Obi that little bit more flexible. Hats off and thanks!

Hi, I just bought Obi Fluid and I'm having issues with very poor performance inside Unity. Most of the samples quickly fall below 15 fps and it seems that collisions are breaking down, especially with thick fluids. Running a release builds of the sample projects also didn't help.

My cpu is far from modern however I expected  it to capable of running reasonable scenes, especially the samples. I have an 8 core AMD FX-8150 3.6GHz. I'm running windows 10, 16gigs of ram, and a GTX 1080 Ti.

I need somehow to know that all particles are in sleep state. Because I need to stop simulation then, save simulation mesh etc. 
For now I use just a timer, but I want to use some smart way to check simulation done. So basically I need to know a percent of perticles are in sleep state and if like 99% in sleep state then considering simulation done.

It there a way to do what I wan currently?

Hello,

I've been doing a lot more work in the HD pipeline and was hoping to use the fluid setups in there.  Do you have an plans in the future to create compatible shaders?  Is there an easy way for a user to edit them to make them work?

Thank you so much for your awesome work ^_^

Hammy.

Hi!

I need to simulate earth for a heavy simulation machinery. I wanted to ask, is it posible to tweak ObiFluid for that purpose?

Thanks!

Is there a way to do not-real-time simulation in the background without affecting FPS? 

I need to do a complex simulation with lots of substeps with high poly meshes and this affects fps. So I am going to show some progress bar and do simulation in the background.

Is this possible somehow? 

I need this for Cloth and Soft Body simulation.

hi, i been trying to make a grapple hook similar to the included one in the package,when i shoot the hook game object and it sticks to other objects i need the robe to be much less stretchy.im using a simple script to control the prematers of distance constraints ,it works fine and it changes the parameters correctly .the problem is , it only changes the numbers .the real changes only going to be applied when i insert the numbers to obi solver manually.
how do i change the distance parameters like iteration and relaxation by script and see it actually happen in the play mode?
and here is the code:

public void less stretch()
    {
        obiRopi.GetComponent<ObiSolver>().distanceConstraintParameters.iterations = 38;
        obiRopi.GetComponent<ObiSolver>().distanceConstraintParameters.SORFactor = 1.5f;
        
        
    }

While trying to look through Simple Fluid sample scene to find out how Simple Fluid Renderer works,
I've found out two sample scenes - MultipahseFluidBuoyancy and SimpleFluid - don't work properly.
All other scenes works fine.

My Unity version is 2018.16f1 and I've downloaded the asset on 8/17/2018.

Could you tell me how to fix it?

I've got multiple crashes during simulation of hight poly cloth or after level unloading with ObiCloth after simulation. 
This looks like an internal crash produced by corrupted memory.
Unity also may throw a C# exception regarding some parts in code that never crash before (like a crash in transforms deep inside Unity) or crash with "pure virtual function call"  exception or just crash with a different stack trace (way more often).

Example of most common crash stack trace:

Hello!

My current fluid setup uses a mesh collider with the obi collider. When the mesh changes the obi.collider does not. The workaround i found for this is to delete the obi.collider and then re-add it, all in the same frame. This updates the obi.collider with the new mesh and everything works well.

A problem I encountered with this is that the destroyed obi.collider still maintains a reference to an object somewhere and therefore doesn't get fully destroyed by the Garbage collector and slowly adds to the memory until it crashes.

I've tried removing the 'Source Collider' in the Obi.Collider and re-adding it, but this just seems to disable the obi.collider entirely.

Is there a way that i can 'reset' the Obi.Collider once changes in the Mesh collider have been made?

Thank you!
