Obi Suit - Questions about cloth in characters

[josemendez]

Hello there!
I am planning to make suit on character with simulation that will make nice wrinkes and will react to character underneath.
I wish to check your demo scene with guy with long coat but it's broken.

I am trying to work on UnityChan instead.

I figured out some stuff. That scale of simulation have to be same as object and about numbers of particles in obi solver.

But I am afraid about mesh. UnityChan has sleaves with thickness. As well as my suit. No matter who do I try i cannot make inner part of mesh don't flow over outter mesh. I got confused with what influance moving backwards and what option shows how much mesh can run forward.

I am trying to make mesh less and less stiff (following rig) closer it gets to exit of sleave. But it's all flows like some jelly not like cloth. Paiting weightes is weird here.

Why I am here:
How to make mesh with thickness work good. Or maybe we should remove inside mesh in places where it's not seen.
How can I smooth weighes alongside mesh
I wish to have nice wrinkles in places where cloth curves.
Will that backstop radius enough or I need colliders for stuff like pants.
How to make it not act like jelly.

Thanks a lot!

- How to make mesh with thickness work good:

Use proxies:

By using a proxie, you can perform the simulation on the inner layer of your cloth, and make the outer layer just follow it.

- How can I smooth weights alongside mesh:

I assume you mean how to smooth particle properties: for this you can use the smooth mode of the particle editor's painting tools:

- I wish to have nice wrinkles in places where cloth curves:

Increase the "max bending" parameter of your bend constraints, or disable them completely:

- Will that backstop radius enough or I need colliders for stuff like pants:

If your cloth is always very close to the body (pants, shirts, etc) then skin constraint's backstop will be enough. For stuff like trench coats, capes, scarfs and such (that can move freely around the body), colliders can be a better option.

- How to make it not act like jelly

Increase the amount of constraint iterations (specially distance constraints) in the ObiSolver. If your setup allows it (i.e, you have at least some fixed particles), you can use tether constraints to completely eliminate stretching:
