First, I apologize for the inexperienced English.

I bought the OBI Cloth, was amazed at its outstanding performance.
(I Created Vertex Animation with Unity physics. but that is Garbage.)

I want to create an object that restoration after Physical Collision.(like rubber)

Which parameter should be modified?

and Is there a page with a description of the parameter?


Thank you for help me.

But when I applied it to my project, there was a bit of a problem.

I think I need a little more study.

Hi!

In the docs you have a detailed explanation of all constraint types and their parameters:

To change the stretching behavior of the cloth, tweak the distance constraints "stiffness":

Also note that the higher the amount of constraint iterations in the solver, the higher stiffness you will be able to reach for any constraint type:

cheers,

For an easy explain,

The painting represents the teeth and gums.
And, this teeth rotate and change size.
I want to change the shape of the gums with change the teeth.

However, set the stiffness low, the corresponding areas of the gum is subside.


Thank you for your continued reply.




Hi!

I'm afraid I don't understand your diagram at all, sorry .  It seems like you're trying to get the cloth to stay wrapped around some object but it falls down, or something similar. Can you try to explain your problem in words?

cheers,

Understood. 

Gums are a very stiff material, very different in behavior from cloth. You might be able to simulate them to some extent by using volume constraints (which are designed for balloons and similar inflatable objects), but for a material that stiff you should use a softbody simulator, preferably a volumetric one (that uses tetrahedral meshes) instead of a cloth simulator.

To be able to use volume constraints, make sure that your gums mesh is completely closed (has no holes in its topology, through which air can escape). See:
