I have a rope which I need to know when it is being pushed or pulled or in other words to know what is the tension applied at one end of the rope.

I don't know how to start in the scripting in order to get that parameter available. Can you please support me or give me a hint?

We have issue with rgb texture for particles. In "import menu" texture is checked for "read/write enabled", but once we click "load propery" obiscript still says "texture is null or not readable".

What can cause this?

We have a problem with the ObiRopeCursor not working as intended. We want a long rope that can extend and decrease it's length from one end. Here is what we have tried doing.

• Open up the crane scene since the behavior of the rope there matches our goals.
  

• Create a new fully set up rope from Scene menu (right click) → 3D Object → Obi → ObiRope(fully set up).
  
• Remove the solver component form the new rope and drag the already existing solver from the scene( this is for making sure we have a solver that is configured properly for this kind of rope) to the ObiRope solver field.
  
• In the pooled particles field of the ObiRope component set a value of 200.
  

• In the Mesh Renderer component in the Materials field at element 0 we assign RedRope material.
  
• In the ObiRopeExtrudedRenderer we change the UV Anchor to 1 the UV Y scale to 5 and we deselect the normalize V bool variable.
  

• The next step is to add the ObiRopeCursor. With the rope set up as it is we configure the cursor normalized coord to 1 and we leave the direction bool variable enabled so the new particles of the rope instantiate from its right side(from the camera view).
  
• Now we go to Edit Particles and fix all of them in place except the one that is on the right edge.
  
• We add a simple script to change the rope length with the cursor.
  

Hi! I can't find any system for detecting and preventing self-trapping. I.e when cloth folds in on itself and gets stuck in its own self-collision. Do you have any suggestion as to how to prevent this?

Hi,

I'm currently playing with a lot of AssetBundle import/exporting in 2018.3.11f1, and I've noticed I'm getting occasional (trying to pinpoint repro) hard crashes with no warning, just a short hang followed by unity crash handler.
The editor log stacktrace is:

After having upgraded to unity 2019.1, reinstalling Obi to latest version and having to redo all cloth setups, an error persists
"Bone weights do not match bones"
The cloth is being applied to skinned meshes of course.
Hardly any info is available on this error and can't pinpoint the cause at all, so I'm assuming it's due to 2019.1 API changes that Obi has not been keeping up with.
I would like to know if staying in 2018.3 is the only choice, if I will have to ditch Obi or will it update to 2019.1?

Hello there,

Thank you for the latest upgrade to Obi 4.1. The distance fields are a lot more accurate now.

However, in the previous Obi version, I was able to use this code to simulate Obi Cloth physics:

Physics.autoSimulation = false;
for (int i = 0; i < 350; i++)
{
    Physics.Simulate(0.02f);
    obiSolver.AccumulateSimulationTime(0.02f);
    obiSolver.SimulateStep(0.02f);
    obiSolver.EndFrame(0.02f);
}
Physics.autoSimulation = true;

However that code no longer works for Obi 4.1 (tested using a fresh project).

How would one go about simulating cloth physics in Obi 4.1?

Thanks

Hello,

I am using Unity 2018.3.10f1 and Obi 4.1.

If I create a new 3D project and import Obi Cloth, there is a compilation error:

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


After I delete that script the error goes away.

Another crane type issue I'm afraid.

I have a very simple setup while waiting for final art and I have added two ropes fixed to a movable trolley. Unfortunately as soon as I run the game, both ropes fixed points immediately jump down to a lower position and I have no idea why. It happens with ropes I have copied and pasted straight from the sample scenes for both the lift platform and the crane.



Any idea of what is causing it?

Hey, was wondering what would be a good way of making something similar to a fixed joint between a rigidbody and softbody?

I need both bodies to be able to effect each other which is why I initially went for the pin constraint, but it does not fix the objects to each other a rigidly as I would like.

The desired effect is to pin a softbody on top of a rigidbody, two balls stacked on each other. I'll be using the rigidbody to move around while the softbody follows around on top being wobbly. 

Any ideas on how to do this through script, or any way I can modify the pin constraint to make it completely rigid?
