Hi,

I've used Obi Rope in a project and it seems to work fine on my computer but really lags badly on low - middle end mobile phones. High solver iterations and low fixed-timestep is not a good mix for mobile.

I need to hold rigidbody objects between ropes and guide them with ropes. Like the elastic ropes outside boxing rings which bounce people back inside the ring. Ropes need to catch collisions without having too many particles or solver iterations so it doesn't lag on mobille devices but also need to look kinda stiff.

Obi rope actually works really well on Mac but lags bad on low-end phones. I need a lighter solution. Is Filo better for my use-case? Can Filo catch moving rigidbody objects and push them back like an elastic band without costing fps on mobile?


Thank you for your assets.

Hi 

I have been trying to use an object with a property of type articulation body as an attachmen and the physics system makes the cable stop working completely since the object starts a free fall movement completely ignoring the cable.

thank you very much to whoever can help me

I'm working on a AR project in unity that requires fluid simulation and I have recently come across your asset "Obi fluids". 
I was able to build the project using Vuforia on my mobile and was able to see the liquid simulation, however as I tried to build it for my magic leap device, the project doesn't get built. 

I came across this post (http://obi.virtualmethodstudio.com/forum...hp?tid=868) in your forum and tried out the suggestion posed there, however I got 30+ namesspace errors while trying to build it to my device. I am not sure how to fix this issue.

Could you please guide me on how I can deploy it on my Magic leap device as this is really needed in my project.

Your help would be greatly appreciated.Awaiting your quick response.

Thanks in advance

Please find our video snip below. What you're seeing is a fluid and we tested this in Unity Editor and Android devices and the fluids effects were colorful ( pink , green , yellow ) however in IOS devices these colors don't appear and it's all pure black.

Hello, I am thinking about changing over from unity cloth to Obi Cloth.
I hope to use Obi Cloth and later Rope for the "classic" sail cloth use case.

I think it should all work, but one thing I could not find any info about, except here on the forum where the founder has said that Obi Cloth cannot be scaled.

With Unity Cloth, scaling the transform will actually fold(albeit awkwardly) the cloth. Is it possible to simply fold an Obi Cloth the same way?

Say I have a square sail cloth hanging down.
I want to pull the bottom particles up (1 fold)and then I want to pull the middle particles up(second fold) and then pull up the particles between middle and top for the final (third fold).
Best case scenario(what im trying to achieve): The sail looks packed up and not catching any wind.

First off is it possible to modify particles like that at run time? And second is it possible to set this up for a ship with 30 sails? And finally have you ever tested how many sails can be simulated at once? Would you think 200 sails(outlier max case in my game) is performant maybe I can set the simulation iterations to 2 instead of 1 as I saw in your YT tutorial thats the main "performance slider" for obi cloth.


Thanks a lot!
 I hope these assets can bring my game to life! I already have a lot of work done and a build demo but with Unity Cloth it just isnt it right now.

Cheers

Hello,

I would like to know if it is possible to apply flexible attributes to a 3D Unity object with the Obi Rope asset?

I have a realistic 3D object, but it is rigid, while in life it is flexible.
Is it possible to use the Obi Rope asset, and using different means, make my object flexible and manipulate it?

If yes, could you explain me how, redirect me to explanations or tutorial videos?

Thanks in advance,
Sincerely, Xameal.

How I can draw a spiral on the rope?

How to use custom shaders with the rope? Is there any sample?

Hi,
I am generating obi cloth for small square shape mesh. The particles are not coming at the edges and corners of the mesh.
So I can't able to attach the cloth to another object. Please help to solve this.

Hi,

I'm using URP with OBI Rope, but I'm getting the well know Shader errors.
What could it be ?

See screenshot : http://tools.quadbyte.net/snap/Unity_sYu1pmaPFZ.png

Thanks in advance for your precious help.
