I'm using physX SDK 2.8.1.

I created two ballon made of physX cloth but they just went through each other.

I doubt whether physX supports the collision between different pieces of cloth.

I know collision between cloth and rigid and self-collision in cloth is available.

Thanks!

It looks like it's not supported even on 2.8.3. Watch this youtube videos:

A test to show that it's not supported:

A workaround (but not applicable to clothes):
