Help I want to make it so that I can grab the torn stiff cloth without any problem.

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.


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?


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

Thanks to you, I was able to make what I wanted to make.
