Number of Fluid Particles in Container |

Hello
I am trying to do a pouring task wherein the user is required to collect water from a faucet in one cup, and transfer it to another.
The final score is determined by the number of particles that were poured from the first cup to the second.
So for instance - - Let us assume total particles are 1000.
- The user collects about 800 (misses 200 in the beginning).
- And finally pours 200 (600 fall on the ground) into the second cup.
- So the final score is 200.
How can I keep track of these numbers?

ObiRigidbodies (or ObiColliders?) causing weird physics |
Posted by: khalvr - 09-02-2018, 11:03 AM - Forum: Obi Rope

I have recently had issues with a multimeter object in my scene. It consists of a rigidbody with a mass of 2kg, attached to two probe cords which weigh 10 grams in each end (the closest ends are attached with FixedJoints to the multimeter). The cord visuals are simulated using ObiRopes with a handle attached at each end, and spring joints to enforce the distance constraints. My problem was that despite the large weight difference between the probes and the multimeter, the probes would exert an unrealistically large pulling force on the multimeter, for instance when you dropped it on the table, ultimately pulling it down. After much searching i found that the problem was caused by the fact that the multimeter had an ObiRigidbody and an ObiCollider attached to it (the probes had none). Whenever i removed the Obi components from the multimeter, the problems would go away, and reappear if i added them. Now, i get that the Obi physics world is simulated separately from the PhysX world, but i still don't get why the ObiSolver perpetuates the motion of objects despite this being handled by PhysX. Ideally, ObiRigidbodies would only be used for exchanging forces between a rope and a Rigidbody and not interfere when there are no pin constraints used.
Also, i'm having serious issues with rope particles passing through/getting stuck in walls, despite the wall colliders being up to a meter thick (see attachments).

Platform : PC
I made a fresh new project and imported the Obi cloth and I got this error :
DllNotFoundException: libOni

Please help as I cannot even start playing with the plugin.

handles on Obi Rope cause twitching |

Since i switched to using handles on my cords, the rope has started twitching in a very odd way which reminds me of an issue you sometimes get when using a skinned mesh renderer with dynamic batching in Unity. The thing is, dynamic batching is disabled for my project, and it appears that it is the particles themselves who are twitching (see gif). What can i do to fix this? I decided to fall back on ObiRope just for the visuals, but now even that seems to have its issues.

Skinned character with a non-skinned garmet |

Hello. I purchased the Obi Cloth and I was playing around with it. It is a good tool. I used it even for toon stylized dynamic hair and works wonderfully.
But I'm wondering if the following scenario is possible:
1) I have a rigged/skinned/animated character skinned Mesh.
2) I have a T-pose robe (i.e. the coat from the demo you provide with the asset) BUT it is not skinned/rigged.
3) The robe (2) is designed to cover naturally the (1) character Mesh in T-pose.
Is there any way with Obi cloth asset or any of the other assets provided in the package, to play the animation in the character Mesh (1), and the robe (2) to ACTUALLY FOLLOW ALONG that animation via colliders or something?
Like dressing my character with different Meshes (robes (2)) and not having to set-up the rigging/skinning of the robe Meshes (2) in 3dsMax as well?
And if it is possible, is it too much performance-expensive?
Thank you in advance.
Great tool I ll write a review in the asset store!

Collision & Stickiness to Moving objects |

Hi,
We just got Obi Fluid for our little project because it just looked awesome (and it is!)
I've taken the FluidViscosity scene and the Obi items within it, and repurposed them in my scene with some adjustments and it looks great...but now I'm wondering how I can, or if, the obi particles/fluid will stick on a moving object - they just slide off right now even with all the stickiness parameters increased.
- The example attached is just me moving the (grey) object that the particles land on.
- The Collision Material has a Friction of 1, Stickiness of 1, Stick Distance of 0.2
- The Emitter Material has a Smoothing of 1, Viscosity of 2, Surface Tension of 2
- The Solver is default from the Sample Scene (I think), Collision Constraint is Enabled, Stitch Constraint is Enabled, Density Constraint is Enabled

Issue with Rope (Chain) in scene |

Hi,
I created a chain (similar to the example scene). After I saved the scene, it works.
After I continue to work on my scene (without making any changes to the chain), I notice that the mesh for chain shows up in the scene view (when its not running ) and I can't select it. Even if I delete the Obi rope from the scene it stays there, until I reboot Unity.
This in itself is a bug, however my real issue is that at this point if I bake Occlusion Culling in the scene, the Obi Rope causes the scenes Occlusion Data to be corrupted. This prevents me from opening the scene (it crashes every time), until I manually delete the Occlusion Data for the scene.
If i remove Obi rope from the scene, I can then re-bake the Occlusion Culling and I have no more issues.
Note: I also have Obi Cloth installed and I have no issues with it.

Build size on mobile |

This may be a silly question (certainly lazy of me anyway) but I couldn't find any info on this.
I am in the design phase of my project and am curious what the approximate build sizes are for cloth, rope and fluid on IOS and android are.
Just checking that these features won't figure heavily into my 100mb budget since AFAIK they are using their own physics library.
Unity is still a bit new to me, so I'm not sure by looking at the package files as to what gets included in a build...
Thanks for any info.
