OK what is my best next step ?

How do i uninstall OBI  ? if i delete it in the project folder it re-appears in afew seconds  ( how do you uninstall OBI ?)

My project is an VR project not really wanting to go back to 2018  when is the update coming ?

here are some of my errors

Assets\Obi\Rendering\ObiDistanceFieldRenderer.cs(7,27): error CS0246: The type or namespace name 'ObiCollider' could not be found (are you missing a using directive or an assembly reference?)



Assets\Obi\Rendering\ObiSoftbodySkinner.cs(27,10): error CS0246: The type or namespace name 'ObiSoftbody' could not be found (are you missing a using directive or an assembly reference?)



Assets\Obi\Sample Scenes\SampleResources\Scripts\ColorFromVelocity.cs(11,27): error CS0246: The type or namespace name 'ObiActor' could not be found (are you missing a using directive or an assembly reference?)

Thanks for any help =)

I am a noob to Obi.  I am trying to create two rods attached to a rope like a tightrope. 
The rods are vertical and a set distance apart and the rope runs between them--again think tightrope.  

What I want is when an object collides with the tightrope (obi rope), if it is heavy enough, it bends the support poles ( obi rods toward each other because of the colliding object).

I have set up the Obi rope so that it is tight by freezing the translation of the end particles. I have increased the tether on the rope so that it is tight. It responds as expected when a object collides with it similar to a taught rope. 

I am having a difficult time setting up the Obi rod so that it remains vertical similar (tightrope support pole) with some ability to bend, and then responds to rope stress ( heavy object falls on tight rope causing support poles to bend sideways).  

From the manual appears like pinning is the choice to get them to react to each other, but how do I just pin it to the end of the rod(instead of the whole rod game object), do I need to add a empty game object and parent to the last particle?

My questions:  
1. Is a rod for the support pole the best choice?
2. How do I get the resting state of the rod to be verticle and attached to the rope so that it acts like a spring when rope receives a heavy object collision. 
3. Do I need to add a empty object that is a child of the last particle and pin it to make the rope attach to the pole and respond to its action like a spring bending sideways?

I can add images if this is confusing--let me know. 

Thanks for any help.

It would be useful if there was a callback method for detecting when a rope tears.

Right now it seems like the only workaround is to watch the number of particles in the rope for changes, but if you also use the ObiCursor all the time, that's not clean or reliable.

hi all;

When the game starts with a scene containing any Obi Fluid particle emitter, we get a 100% crash.

We have the following call stack:

Of course it works on all other platforms, iOS, PC, etc... Just iPhone XS crashes everytime. Now our publisher has blocked the project, and there is no way for us to release it without a fix.

Does anyone have the same issue?

Hello!

I've been having a blast with the soft body asset and am trying to get used to not working with a rigidbody. I'm only a novice game designer and I hope this is just something easy I cannot figure out.

I'm having a ton of trouble coding a movement script and setting up constraints to make a ball (like in the Ballpool demoscene) a moveable character. I tried using .AddForce in particular directions but because the ball rolled around it's up, right and forward were always changing. I tried to constrain it so it wouldn't roll but found that wasn't easily achieved. I coded a .Clamp onto the Ball that has the SoftBody but it still rolled around while what looked like an Empty Game Object adhered to my code. After some reading I think it's because it's made out of particles and not a continuum material like rigidbodies? Anyways, I'm scratching my head figuring out how to do this and I'm sure I'm over complicating this. 

In short: how do I constrain the x, y or Z of soft bodies and accurately apply force up, forward and right no matter how it has rolled? 

Thank you for any feedback.

Hi there,
I am currently experimenting with runtime length modification (working great!)

However I don't yet know what the optimum number of pooled particles is. Setting to 1000 was more than enough, however I noticed that upon trying to reduce the count that the editor value does not seem to be used but rather the value that was cached upon initial initialization.

Re-initializing solves the problem, however, in doing so my handles (created via the editor) no longer function, requiring them to be re-created.

Is the pooled particle count not updating a bug? If not, is it necessary to re-init or am I missing some workflow steps? / Generally doing things wrong?

Thanks,
Chris

Hello,

I'm checking out Obi Fluid now and it looks great. I'm wondering if it's compatible with Unity 2018.3 and specifically the HD render pipeline?

I tried searching for this but couldn't find anything. Thanks.

Hi,

I've used Obi Rope successfully on a windows machine.
When loading the scene in a Linux editor, I get the following errors:

Hi there,

For my setup I have an Obi Cloth component added to SkinnedMeshRenderer object that also contains blendshapes. These work fine without the Obi component attached, but with it enabled the vertices seem to displace in the wrong direction. I have uploaded a quick recording showing this problem here.

I have tried different update and simulation methods, with and without a proxy, but none of it seems to help. Is this at all possible, or is there some kind of fundamental conflict here?

Important to note: I am using Obi Cloth 3.5 on Unity 2017.4.

Thanks in advance!
