[] Ocean surface simulation (VaOcean)

Hi all, can anyone tell me what am i doing wrong?

See, i place the BP_VaOcean_simple to the level.
The is ok
But nothing happens, it wont move, ocean is still.

When i tried using BP_VaOcean_FakeSSS it works but the VaOceanStateActorSimple does nothing in either cases.

Also, using the “fake” one has strange poor details, it appears to be flat from close.
And i did the Level Blue print as it asks to do in the “How To” link.
