NVIDIA GameWorks Integration

Newbie question, why do bouyant objects not change rotation on the WaveWorks ocean? All objects can move around, but they don’t seem to rotate at all on the water. ://imgur/4nqlQwj In demo the ship rotates, am I doing something wrong?

Thanks!

EDIT: Another question, how can I set Waveworks to only interact with certain static meshes instead of everything? When I set any static meshes to Static, the game runs slower and slower until eventually it crashes, and when I set the static meshes to Movable, then they float along with the waves no matter what I try.
