Use staticobject dop and turn on Use Deforming Geometry. Turn on Show Collision Guide Geometry (Show Guide Geometry if using bullet based collision) to see whether it's generating proper collision shape. You can feed your own volume in Proxy Volume and set Mode to Volume Sample this way DOP will read collision volume from SOP.


If you are using bullet based collision then turn off Use Volume Based Collision Detection. Play with Geometry Representation and  Collision Padding.
