Guitar-like string - MoonglowStudio - 18-05-2022
Hi everyone!
I've been trying to get a rope to be :
- Very tight : achieved good result by getting the Solver > Constraint settings > Distance setting to 10-20 iterations. This however creates the next problem.
- Vibrating a long time : with the setting above, the rope gets to a halt in a very short time, even though Damping is set to 0.
Would you have any suggestion of setting for having a tight rope that vibrates a long time on plucking, just like a guitar's string?
Thank you

Hi!
You want to increase the temporal resolution of your simulation, basically allowing particles to change direction -vibrate- more than once per frame. You do this by using more substeps, which you can find in the ObiFixedUpdater component. Using just 1 iteration and many substeps (10-20) will do.
Check out this page, it goes into detail explaining why using more substeps allows for less energy dissipation and results in more lively simulations: http://obi.virtualmethodstudio.com/manual/6.3/convergence.html

Works perfectly, thank you very much!
Combined with some advices for VR performance the feeling gets real nice.
