Before buying the full suite, we wanted to check and see which assets are compatible with 2018.3 and SRP projects:

Obi Fluid - looks like 2018.3 is supported but NOT SRP?

Obi Rope - Same as Fluid

Obi Cloth - Works with 2018.3 and SRP but requires material swap from default?

Obi Softbody - Works with 2018.3 but NOT SRP?

Do we have these correct? Really hoping to implement Rope and Fluid into our HDRP projects. Thanks!

Help, Someone can give me a sample script of Coloration & thickness for Obi Rope?
I'm coding idiot ... dunno how to achieve those cool effect as blood vessel ...

Hi, I'm wondering if Obi Fluid can generate visuals similar to CFD software, such as this video demonstrates:

We are trying to create a virtual Wind Tunnel in Unity to demonstrate airflow properties around airfoil shaped objects and other things. I've been looking into importing vector fields from Maya Fluids and Fume FX but it would be really cool to be able to do something in real-time. We will have control over the hardware it runs on so we can build something with a lot of CPU/GPU power.

Another thing we'd like to do is the classic wind tunnel example using a car:

Even if it can only do it in 2D it would be useful as here:

I just haven't seen any demo videos of Obi Fluid that show this type of fluid simulation.

Thanks!

I want to achieve a kind of simulation that the soft body can be picked up by a pair of chopsticks. The problem is that the chopstick is thin and will always pass through the particles. Even I increase the collision iterations. The particles will be pushed away by the chopsticks (use low shape matching stiffness). The particle picker can just pick and drag one vertex. If I want to achieve the whole softbody picked up and clipped by another physical object (rigidbody chopstick). How to setup the softbody? 

Do I need to combine both shape matching and distance constraint ? So the shape matching can maintain volume while the distance constraint can maintain particle's connection (not to be pushed away while collide with chopsticks). Does that mean I need to Obi Cloth ? Is it possible to setup a soft body object using both Obi Cloth and Obi Softybody?

Hello,
I just can't get Obi Fluid to simulate waterdrops on a plane to behave remotely like this one:

Would you please shed some light on this problem? any help is appreciated.
Thanks.

Hi, I just bought the Obi Cloth:


I'm trying to integrate Obi Cloth to my current project for skirt simulation for my characters. I followed the tutorial: http://obi.virtualmethodstudio.com/tutor...thing.html

However when I play my game the skirt change its position and practically undress my character.

I'm using Unity 2019.1.0f2

Crash occurs on iOS (iPhone X, iOS 12.2) device shortly after the app starts. Note that this crash does not occur in the Unity editor or on Android. Using the latest version of ObiRope and Unity 2018.3.14. Crash log is pasted below:

Is there any way to swap between 2D and 3D mode on a obi solver (fluids) in runtime? I am trying to access the variable/parameter trough scripting, but I can not find a "Mode" on the Obisolver. Either I am looking in the wrong place - or the answer is "no you can not"?

And since someone always asks "Why would you want to do that" let me clarify that I understand I can not do both 2d and 3d at the *same* time.   
It just would like using the same one solver and swap between 3d and 2d mode and keep all other settings - instead of setting up another one and point emitters back and forth and make sure all things match up. It is a visual effect thing that happens in between some other things in a visual art thing.

Hello,

I've isolated a problem with the way Obi handles reflection. To fix my problem simply, I need to know where the Fluid Renderer is considering reflection, and disable it entirely.

If anybody could help, that would be great.

Thanks in advance, I look forward to swift replies

Hi,

I've encountered another issue. When I look slightly away from the particles that have been spawned, they lose their colour and look washed out. I'm using the Fluid Renderer component on my main camera.

Any ideas?

EDIT #1: I'm using Deferred lighting, and swapping to the other versions of lighting in the camera to Forward solves the issue, Use Graphics Settings and Deferred (which we've built our project around) have the issue.

EDIT #2: It's to do with the reflection probe in the scene. I turned it off and the problem was solved, but when I turned it on again and put the particle on another layer and this didn't work.

EDIT #3: I began work on another particle effect because I can't proceed until this is fixed. The particle isn't related to Obi Fluid, but it fixes the issue when it's active. When it's inactive the problem reappears.

EDIT #4: Further testing has revealed that the error is present with all Obi particles regardless of position, rotation, etc. It is to do with the Fluid Renderer script that can be attached to the camera.

EDIT #5: It's not to do with directional lights. I turned them off and the problem persisted.
