Modify the polygon of the left side.
I know that there are some bugs when changing the surfaces of the real
polygon makes the "distorsion" in wrong surfaces (not in all cases).
In this scene appears a polygon with a copy "distortionated" of it.
I maked a script to copy a polygon's surfaces and spawning other polygon wwith the same surfaces modified, namely, I use randomness numers to change the surfaces.
This makes a polygon to be like refection on the surface of the water.
So I thought that this scene could be useful effect.
I think on making a group of objects to be only one polygon, just setting the points of the surfaces of a body, you may dont understand what I said but when I upload the next scene you will.
