Hi 

The idea is to have a costume consisting of approx 50 non-stretchy ropes, attached to an avatar (animated with mocap suit) and previewed in VR in real-time. 
The problem is that even a simple prototype with 6 ropes with low resolution and length is running 10fps only, which makes it unusable for my use case.

What I have done
-created Rope Blueprint (thickness: 0.003, resolution: 0.1, pooled particles: 0, length: 0.3m)
-set up 1 obi solver (distance constraint iterations: 10, substpes: 1)
-created 6 ropes (used particles: 55)
-attached each rope to joint of low-poly avatar (using obi particle attachment)
-added 4 capsule colliders to avatar to avoid ropes going through body

I'm using Obi 5.0 in Unity 2019.2.9f1 on a PC with i7-6700 processor and GeForce GTX1070. 

The question is what is causing the performance issue? Does it have to do with the rope setup itself (and if so how to set up the rope in order to be efficient in terms of performance and also look quite stiff)? Is it because each rope is attached to the avatar's join which is moving quite fast? Or what else can be causing and and how it can be fixed?

Thank you in advance

Hi,

I am having troubles getting a 2d rope to render. I want to use line renderer to display the rope.

• Created a new scene
  
• Built a new blueprint
  
• Added a rope
  
• Set the solver to 2d mode
  
• Removed the extrude renderer
  
• Added a particle attacher to the first control point so it wouldn't fall
  
• Added a line renderer
  
• Pressed "Play"
  

Hi ! 

 i  recently purchased obi rope plugin couple of days before . i am using unity2018.4 for my project.. Current version doesn't have  support for

I wonder whether obi rod could implement this in the above vedio. Jump straight to 58 seconds.

There are some key features which I think should be pointed out first:
1.  The black line in the vedio is made of metal in reality. It is highly resistant to stretching and twisting but easy to be bended. Most important of all, it is very stable for there is almost no jittering while moving(I have tried the obi rod but it jitters a lot while moving).

2.The blood vessel which around the black line could collide with the black line. The vessel animates periodically so it can be seen as a rigidbody rather than a softbody because the animation is known prior. 

So does obi rod could implement this? I have implemented use finite methods,but the collision force is hard to compute.

hello (btw i have bought this asset)

with obi 5 i can rarely get a mesh to show.
following the video tutorial normal meshes like the built in shapes, cube, sphere, work fine, however
just about any other mesh does not show.

when i am creating the blueprint the particles, constraints and mesh show fine. but when i put them in a level, assigning the blueprint to a soft body asset, nothing shows up.
the object falls with gravity etc but the mesh is 'invisible'

any ideas whet this could be?
unity 2019.2.14f1

thanks

edit:
here is one i tried just to test

Just want to be brief and say thanks for continuously making Obi assets what they are today and being very attentive to your forums!

Hi,

I'm an inexperienced developer and I'm not sure how I should be setting the ParticleGroup of a ObiParticleAttachment component via c# script.

I've checked the sample code and google, but it's still holding me up, anyone care to help out? 

Thanks in  advance,
Bobs

Hello, may I ask how to change the mass of each path in Update?

And How do I locate the position of the path in Update? I want to use a 3D cube to move linearly in each path?
