One other area I have been increasingly playing with are the Global Transformation panels. ROTATION allows you to control the direction of the waves- when using a BUMP.

TURBULENCE- has some very interesting effects- both with Water as well as Clouds!

(These are NOT the settings for the above water, BTW)

I find Vue's Materials Editor a lot more easy to figure out than the one in Bryce- which always seemed like another PLANET to me...
