PhysX cloth demo / weapon projectile collisions, wind

Collisions) Should the weapon projectiles be interacting with the cloth objects in the PhysX cloth demo? The PhysX docs suggest that cloth objects should be capable of collision checks - though only at vertices. The cloth objects themselves in the demo are marked for "triangleCollision". And the objects do interact, more or less, with the player when it passes through. But the projectiles sail right through without any apparent effect. I would like to experiment with projectile / cloth collisions, decal placement on the cloth objects at collision points - eventually extending the cloth treatment at the PhysX integration level (if necessary) to handle tears.

Wind) Looking through the PhysX docs and your pxCloth:processTick() code, I get the impression that setting enableWind="1" for a cloth object should enable a randomized wind effect on that object - but I am not seeing any effect. What am I missing?
