Hasta La Motion!

I’m not sure if the "plugins" section is the appropriate place to post this topic but well… seemed close to me.

Ok. Here is the question:
I started to play with realwave [realflow] to generate some waves interacting with a geometry.
Here is the little problem.

I have a large scale realwave plane, (50*50) with high resolution (0.2 polygon size). And I have a sphere (realflow sphere) in the very middle of my scene.
I also have a spectrum, connected to my realwave (as my main wave generator)

However, the problem is, spectrum waves are not "interacting" with my sphere. I mean, the ripples do not be reflected (or ripple-back).

How can create this ?

Am I doing anything wrong ?
