  Exceptions on scale 0 Obi rope
Posted by: bobby - 19-02-2021, 04:03 PM - Forum: Obi Rope - Replies (1)

Hello Obi,

when I tween the obi solver size to 0, I get a lot of exceptions. is there any way to remove them? I tried setting solver.enabled to false, but then when I deactivate the solver gameobject, i still get exceptions "Assertion failed on expression: 'ValidTRS()'

It doesn't affect the gameplay, it's just that exceptions appear in the console.

  get position of particles
Posted by: orestissar - 19-02-2021, 10:44 AM - Forum: Obi Cloth - Replies (6)

Hello, 

I'm trying to retrieve the particle positions of 2 Obi Cloth Objectives.

In my scenario, i just created 2 flags with obi cloth blueprints. The two flags are on the same solver but in different world positions. 

Code:
ObiCloth cloth1 = Flag1.GetComponent<ObiCloth>();       
ObiCloth cloth2 = Flag2.GetComponent<ObiCloth>();

cloth1 is assigned to the 1st Flag and cloth2 to the 2nd. All good so far (or at least i think so.)

However, when i use, for example:
Code:
Debug.Log(cloth1.GetParticlePosition(0));

Debug.Log(cloth2.GetParticlePosition(0));

The result is exactly the same Vector3, despite the 2 flags being on different positions 
No matter where i put the flags, the result is always the same.

Am i missing something? Any suggestions?

  Wind Demo Frames Drop
Posted by: StudioTatsu - 15-02-2021, 06:37 PM - Forum: Obi Cloth - Replies (2)

In the Wind demo, using Burst Backend, it drops to 1-2 frames per second. 
Oni backend works fine. No issues.

Tested in 2020.2.4f1, Obi 6.0

Heavy garbage collection coming from CreateConstraintsBatch.

  Burst backend Error in any example.

Hi, just a quick question is that Burst backend supposed to work. I tried with various Unity versions and various combinations of the required packages and it always end up in an error in any of the samples.

  Cloudiness at Obi Fluid 6.0
Posted by: asimofu_ok - 13-02-2021, 05:06 PM - Forum: Obi Fluid - Replies (2)

Hi, I updated Obi Fluid from 5.3 to 6.0.
And I'm surprising at Fluid Renderer parameters.
However, new Obi Fluid can use no longer the cloudiness of DielectricFluid material?

It was useful for white liquid or black background.
Additive blending is difference to cloudiness...

I think it is best that Absorption option can be used for white color.

  Solver Error

Figured I'd begin a new thread as this isn't strictly related to the grabbing issue Jose helped me with recently. I woke up this morning to the following console error:

Code:

It's throwing from the solver that handles the grapple rope, but no changes were made to the rope recently, only to the grappling hook, and the particle attachment was redirected to that new model. The rope isn't simulating and it's preventing other scripts from executing, any ideas?

  Multiple renderers in URP
Posted by: corel - 13-02-2021, 04:31 AM - Forum: Obi Fluid - Replies (4)

Hi,

Is it possible to have multiple renderer passes in URP specific to separate emitters? I aim aiming to have distinct fluids in a scene with different refraction and blending modes, but I can't seem to find where to select specific emitters in the obi fluid renderer feature. I thought this was possible using the standard pipeline when the renderer script was attached to a camera, apologies if I've missed something obvious.

Cheers!

  Getting actors from bodyA and bodyB in Obi 6.0?
Posted by: MattS - 12-02-2021, 10:54 PM - Forum: Obi Softbody - Replies (6)

Hi!

I've updated to Obi 6.0 and replaced contact.particle with contact.bodyA and contact.other with contact.bodyB, but when I collide 2 actors now, after the first collision or so none of the contacts are the 2 actors involved in the contact; most are null. 

Code:
public void OnSoftParticleCollision(object sender, Obi.ObiSolver.ObiCollisionEventArgs e)
{
    foreach(var contact in e.contacts)
    {
        if(contact.distance<0.01f)
        {
            var thisActor = m_solver.particleToActor[contact.bodyA]; // often null
            var otherActor = m_solver.particleToActor[contact.bodyB]; // often null
            ...

world.colliderHandles doesn't seem to be right either. I was wondering, what is the correct way to get the 2 actors involved in a softbody/softbody collision now?

Thanks!

Matt

  Surface-based collision option not working
Posted by: budosuyu - 12-02-2021, 03:04 PM - Forum: Obi Rope - Replies (5)

It doesn't seem to work for us. Ticked or not it works the same way it did with the previous versions. Am I doing something wrong? Are there any additional settings I should be aware of? 

I wish there were a demo scene specifically for this new feature as we have seen in the new demo videos.

Can you please help me out?
