Help Question about garment onto a 3d avatar using Obi

[josemendez]

I set each clothes to have each ObiSolvers,gave them the same value. After simulating it, they didn't collide each other.
On the other hand, with one parent ObiSolver and two children, they look good; seems like they did collide each other. 

The top located on the outer layer as I intended,  and didn't pass through the bottom or the body.In hierarchy-wise, I was wondering if there's certain principle in it.

Hi,

Yes, as explained in the manual actors managed by different solvers don't interact with each other, as they're part of separate simulations. See: http://obi.virtualmethodstudio.com/manua...olver.html

Each solver is completely independent from other solvers. Therefore, actors being updated by different solver won't interact / collide with each other. Only actors in the same solver will react to each other.

And I wonder which one is more stable.

Stability wise, having one solver vs having multiple solvers is the same: the core simulation method doesn't change.

Also, I was wondering if there's a way to designate a child that it should be placed the outer/inner layer.

This is entirely up to you. You can designate which actors should collide with other actors using collision filters.

kind regards,
