But it's moving like a cloth. The value I set is as below.
Hi,
Obi is designed to simulate deformable bodies. While ou can make things arbitrarily stiff by increasing the amount of iterations/substeps, this has an associated performance cost (this page explains how the simulation works in great detail: http://obi.virtualmethodstudio.com/tutor...gence.html). Also keep in mind that substeps are much more effective than more iterations when it comes to improving convergence (making things more stiff). You might want to use 20 substeps instead of 20 iterations.
Making really rigid cloth (like a metal sheet, for instance) is extremely costly though, it's not something Obi was designed for. A rigidbody engine should be used for mostly rigid objects.

Can you tell me how to correct it?
If you're using a contact grabber for this, there will be no two-way interaction between the cloth and the input. Cloth particles will follow the grabber wherever it goes and won't resist pulling at all, hence the cloth will tear quite easily since you're applying the equivalent of infinite force when moving particles.
Have you tried using ObiParticleDragger instead (which uses the mouse to apply a spring force to particles), or any force-based method?

Please give me a good answer. Thank you!
I don't really understand this question...what do you mean by " I want to know how to tear it in that direction if there is a tear side."?
kind regards
