Dveyee, big thanks for answering my questions.
I think I will use a terrain with a detail map to achieve (somewhat) realistic water.
Strange, game developement with A5 was easier xD
May I also ask, how to detect width\height of camera (default view object)? The effect that I am trying to achieve is moving and scaling panels to proportionally stay on their places when changing engine window size.
Edit: and a question about bone animations. Is it possible to make the frame's bone angles independent from previous frame's angles? I mean, so changing the previous frame in MED does not 'break' all frames after it.
