Suggestion / Idea I need to config rope
#1
this is my config.

it so soft i need it stronger.  

and this thing i want.

Hi,

You should not use a particle based solver like Obi for this. It's not its intended use case.

Instead, use a cable simulator like Filo:

When I use Filo It can't rotation object still forward rotate.

Hi,

Sorry, I don't understand your question. Can you reformulate it, and/or provide more details on what you're trying to do?

When I used Filo on a crane, the rotation of the hook won't follow the rotation of the car. And I've made a lot of progress in this project with Obirope, so I'd rather want to know a suggestion on how to setup the rope and make it less bouncy.

Hi,

Filo cables do not support torsion, but neither do ropes in ObiRope. If you need torsion forces you have to use ObiRods instead. Here's a comparison table:
http://obi.virtualmethodstudio.com/tutor...ropes.html

To make the rope less bouncy, increase the amount of distance constraint iterations in the solver, and/or reduce Unity's physics timestep. Both come at a performance cost though. Reducing the rope resolution will result in less constraints, improving convergence (higher reachable stiffness). See:
http://obi.virtualmethodstudio.com/tutor...gence.html
http://obi.virtualmethodstudio.com/tutor...olver.html

But again, my advice is to use Filo for this. It is specifically designed for this use case. Using a particle based solver for industrial crane simulation is just doomed to failure.

now I Config rigibody object

it's look better but I have a about distance issues, do you have any suggestions? it stretched.

Do not use parallel mode for this, it converges very slowly compared to sequential. Use sequential mode for all constraints, as you need the system to converge as fast as it possibly can. Quoting the manual:

Quote:Parallel mode converges slowly and isn't guaranteed to conserve momentum (things can sometimes gain energy). So use sequential mode when you can, and parallel mode when you must.

Also, try using 2 subsets instead of 1.
