Hey Everyone,

the team I work with recently bought obi rope and we are very happy with it however there is one thing we could not figure out at all and searching through the forum did not give us any results, maybe I am just missing the right keyword.

Is there a way to start the scene with a rope already in it's relaxed state?


Given the existing API I guess i could write this on my own, enter playmode, simulate idk 100 frames, capture current state of all particles, write them back into the blueprint or another asset and reapply all those values on start next time. 
However it seems like this kind of init / set initial state function should be so common it might already exist?


thanks for your advice

I think that Dynamic attachments have a bug!

When I create a rope and add a Dynamic attachment with Break threshold ( any number from 1-1000 )
Things work as planned at the beginning.
I move the connected object and if force gets over break threshold - it detaches from the rope!

But after I close unity and reopen, or make a standalone build ( windows, osx ) the object can't detach from the rope at all

After I remove the dynamic attachment and add again - it works in the editor, till I close and reopen editor or build a standalone build!


Any tips or ideas about what's going on?

P.S. I tried to debug the code to see what's happening, and found that something strange is happening in function BreakConstraints.
Oni.GetBatchConstraintForces always returns 0 forces! ( even when the object is jumping around ) after you reopen the editor!

Possible a init fail after you reload the project as it works only on 1st time when the dynamic attachment is added.
I hope this helps to smash the bug!

Hello!

Is there are a way to get a callback when Particle Attachment breaks?

Found only that Tearing has a callback.

When i test my game on unity editor obi fluid object collide with ground but when i build a game and test my iphone passes through collider. I tried with box and mesh collider but the result is same. How can i solve that ?

Update: When i instantiate object after game starts its not working. But if i put scene directly its working. But this problem only happening at iOS

Hello, can Obi Fluid be used for blood, when on take damage?

Hello!
Is it safe to use the Obi Rope in Unity 2018.4 
( tested, kinda works, have some errors, but want to be 100% sure )

Thanks for developing such a great product!

Hello,

In my project, I am using stencil buffering technique to masks some specific objects. Lets say A object is the object that I am masking and B object is my mask.

In Mask Shader (Shader that is used for object B) I am using following stencil buffer settings:

Stencil
     {
         Ref 1
         Comp Always
         Pass Replace
     }

In Mask Subject Shader (Shader that is used for object A) settings are like that:


Stencil {
             Ref 1
             Comp NotEqual
         }
         
             
With these settings when B object overlaps within A objects in pixel-wise those pixels are not being rendered. While it is working as expected within other objects (objects having no stencil settings), obi fluid is not being rendered as expected.

At the attached screenshot A object is the blue one. And the square shape is created with my mask object which is B object.
As you can see red object  (Having standart shader) is being rendered through my mask as expected. However fluid rendering is being cut by A object even there is a mask object at those pixels. 

I am not an expert within shaders and honestly, I am learning stencil buffering within this project. Is it possible to render fluids through masks that are using stencil buffering. I have tried to change DielectricFluid shader with different stencil settings but I couldn't achieved any progress. 

Thanks in advance

Hi! I need create rope(obiRope Meshrender) with 2 materials, like this:
   
But in unity, i can add 2 meterials in rope:
   

how i can create 2-materials rope(vertex color not suitable)

Hi, 
is there any method to increase the length of rope while rope is pulling by object?

Thanks

I have multiple ropes with their respected particle attachment. When scene start i want to show random movement like rope hanging on scene start.
