problem soft body interaction with kinematic rigid body

[tanselhalic]

Hi,
I'm trying to interact with soft bodies using kinematic rigid bodies. Particularity, I'm moving kinematic object(which is simply a btBoxShape (with a dimension 0.5,0.5,8)). but every time I move and touch the soft body with kinematic rigid body, it passes through the soft body. In addition, soft body vertices have a very little movement near kinematic object while passing though, However I expect fully seamless interaction. Does anybody have experience with soft body interaction with kinematic objects?.
