Fluid(SPH Particles) collision with cloth in Physx 3.3.2

Hi.

I am new to Physx3 and I want to implement a project to simulate wet effect of cloth based on physical model.
I use Physx cloth and fluid to simulate my scene, and there is two rigid body in it, too. Collisions between rigidbodies and cloth and rigidbodies and fluid are OK.

Screenshot is here.

Now the problem is when the fluid falling down, all the particles pass through the cloth. Just like below.

I tried to increase cloth resolution, but it didn’t work.

Anyone can help me? Key point to solve this problem or other way to achieve my goal to simulate wet cloth.

Thanks so mush. :)
