hi there!
why does i attach both of the side of the rope will cause the original length is stretched?
and how do i keep the original length (like the video before playing)

Before I add the FluidPassCompute, the Fluid only crash when I give it too small voxel size and/or too small Max Surface Chunks value.
But after adding the FluidPassCompute, I have many frequent crash (suppose not related to above fields since I've adjusted them)

Now it's likely crash when I enter or exit Play mode.

The log when crashed

Quote:In Obi 7 all solvers always run in parallel. Simulation starts in LateUpdate(), while still using a fixed timestep. This combines the best features from all ObiUpdater flavors and simplifies setup, as a result, the ObiUpdater component has been removed.

So happy I can make a pool now 
This is not able with earlier versions of Obi whoo.



I'm just testing with a pool size width 20x10 height 3m
To cover this pool, I used extremely big particle (resolution 0.02, count 15k) on a RTX 3070.

Tbh I do not expect a swap chain crash with just 15k particle, since Unity CPU shuriken only has problem at 10k, so I don't think 15k is heavy for GPU.
But the pool will crash when it about to reach 11k particle.

After more testing, I found out this crash is about the Memory Budget foldout. After I set Max Surface Chunks to 150k (425mb) it can run now, but the GPU cry for help 

This is a very important part that will crash Unity if not properly set, so I suggest: when the Emitter detect user give it a very big particle count blueprint, can show a big red warning box telling user must scale the max Surface Chunks accordingly, or even better, suggest a value to set.


Also, in PlayMode the Solver only show Chunks and memory we set, not the Chunks and memory we used up.
Suggest adding to the display used up Chunks  / set Chunks . With that I can set the Max Surface Chunks with better value. For now, I can only blindly set. The values I set may be much more than it actually need. 

Window Build test: 20ms for this pool, optimization tips please?

Btw, the pool is there, I'll move next to scripting buoyancy, if you please can give some demo code about adding force based on character volume displacement inside the Fluid that would be big help!

Hi, happy to have my first bug report for Obi 7 . The problem:
In my UI code, when menu opened, game is paused by setting

Im getting this error 

I want to detect collisions with this character (which has nothing on him other than Obi bone)
Can it be done, or he should have Collider? I think Obi Bone or not, it has particles under it as all Obi things, so I can query its collisions with my character (my character has Obi Collider)
I want to debug the impulse.



The Golem can contact and push my character back, but this code (subscribed to character's solver.OnCollision event) returns no collisions.

An error occurs when magicacloth2 and obi fluid are used together, and the error continues even if magicacloth2 is removed.

What should I do?

Good Day, 

thank you for your time! 
I am currently experiencing rope stuttering in my VR Game. I have made a small video demostration, where you can have a look at how it is experiecned:

Then after watching the video, heres some screenshots from the Components!

I have attatched two screenshots to this, one is the Solver Inspector + Hierarchy and one is one of the Ropes Inspector


Again, thank you so much in advance!
Best,
Nixon

I'm thinking about this idea for a while.
We got: 
-Obi Fluid which is limited in particle count, making something like a pool will be hard on the GPU.
-Obi fluid can advect things near it, like shuriken particles.

So why can't we apply the same advection idea, but instead of shurikens, we apply it to the nearby mesh vertex?

So the idea is we have a pool of Obi fluid particles, which having very large particle scale, and not rendered.
With this we can have any object that jump into the pool will be physics collide and have buoyancy force to pull it up but with low particle count.
And on top we have a plane mesh for the surface, which advected by the Obi Fluid. This way the mesh can have deformation, this mesh can be Fluxy mesh which have 2.5D sim on top to give us detailed waves simulation, while the Obi Fuild give it bigger wave advection.

Isn't this a best of both world? You can make a bridge asset that have 2 requirements that are Fluxy and Obi Fluid. If you can add underwater rendering for it, it will sell like hot cakes.
