Cloth Clipping

Hello there.

We all know how poor is the cloth component in unity, but I have to use in my project.. In this project I have clothes and a customisable model in scene.

The clothes have different sizes, so you can make your character fat, or skinny, and the clothes should work with physics. Thats why I'm using the cloth... Also I'm using UMA (Unity Multipurpose Avatar) for the character.

So, the deal is.. My colliders are clipping in some regions that shouldn't.
Here some screenshots to illustrate.

Green are the simple sphere colliders (that cloth recognise)
White are Conic Collider generate through code (based on ordinary colliders)

My Cloth Config


It happens that the thigh still clipping with skinny character,



So any ideias?

#Edit# I Figure out that thigh collider its not working, BUT I have less then 32 sphere colliders...
