I noticed a couple of issues with cloth.

If I attach a cloth to a vertical pole and set it up like a flag, with velocity on it to make it flap, ok fine. How would I do turbulence in the wind? I don't see any kind of 'rippling' effect in the cloth (though I thought I saw it in one of the demos).

Also, if I put a box behind the flag, and it flaps and hits the box, I can see box poking through the flag. When the flag moves forwards it seems to get caught inside the box and becomes trapped. Any way to prevent that poke-through and subsequent trapping?

PHY SET SKIN WIDTH may help to resolve this issue, increase the skin value.

I did try thickness... but setting that too killed my system, cpu usage through the roof. Hadn't thought of skin with, I'll try it.

Skin width had no effect either.

Here's a sample to show the problem - as the flag swings back, the red cube behind it pokes through, then the flag seems to snag at the bottom and get caught. Change the y acceleration on the flag to something else, and it doesn't seem to happen.
