Hello.

I want to use unity to display a liquid on the screen in VR (HTC vive), but it does not show up.
It shows up fine in a scene without VR.
Do I need some special settings?
I don't know the cause of this problem, so please let me know.

Obi Fluid Version : 6.3
unity Version : 2020.3.16f1


Thank you.

We have recently upgraded our developer machines to Macbook Pro with the M1 (Apple Silicon) processor and want to upgrade to a newer version of Unity that runs natively on it (2021.2.3f1 Apple Silicon version). But when I tried to run the game on that version, I get the error:

DllNotFoundException: libOni assembly:<unknown assembly> type:<unknown type> membernull)

I've tried upgrading to most recent version of Obi Cloth but still couldn't find a dll in it that supported Apple Silicon. Am I missing something or have you not released a version for M1 yet?

Hi.
I keep getting null ref errors from some of 6.3 demos. Right after importing the assets, they seemed to work but now I am receiving errors in some scenes and cannot run them properly. (Can play scenes but nothing rendered.)
The error I get is as below:

Hi,

I have a rope that interacts with a lot of moving obi colliders that make up a human. 
The profilers seems to show quite a high cost to moving all the colliders as needed.
Any tips for increasing performance on moving colliders?

Cheers

I have 3 ropes like in Tangle master. There are optimization problems on mobile when using these ropes. What would you suggest I do to make it work better and more efficiently?

Hello i am using default rope cutting script. But my rope is not cutting where it appear on the screen. 

   

When i try to cut on blue area it doesnt work. But when i try to cut on red area it cuts off the rope in blue area.

i will be glad if someone help me.

Hello!

What was the status of surface collisions for softbodies? If they're not supported yet, is the plan still to support them and and so what's the timeline? 

I think these could be a game changer for me as I find small (radius ~0.5m) softbodies intersecting larger ones (radius ~2m) at moderate speeds and I can't add enough particles in a performant way to stop this.

Thanks for your time!

Matt

Hi,

I just load the sample FullBodyVolumetricSoftBody, and hit the play button, but it shows: 

Unsupported conversion of vertex data (format 0 to 4, dimensions 4 to 4)
UnityEngine.Mesh:SetBoneWeights (Unity.Collections.NativeArray`1<byte>,Unity.Collections.NativeArray`1<UnityEngine.BoneWeight1>)


OS:win10
Unity ver:2020.3 lts
Burst:1.5.6
Collections: 1.0.0-pre.6
Jobs: 0.11.0-preview.6

Please help!
Thanks!

How can I check if two or more ropes are touching each other? As a result of this contact, there will be a flexibility exchange that I want to do.

I created a cube (with default blueprint settings) and tried pressing down on the top of it with an Obi collider, but was not able to effect much change in it's surface. I tried adding in volume sampling, and playing with the shape matching constraints, but nothing seemed to make a difference.

Before I invest too much time trying to figure it out on my own, I just wanted to check to see if this is even possible? The effect I am going for is sort of like this.

I watched the tutorial videos and looked at the manual but was not able to find this addressed anywhere.
