Fill underneath ocean with color - like a cube

coolhand71

Using the ocean gernator plugin which is great but it only does surface, not volume in between floor and surace.

 

Any ideas on how to achieve this effect in Daz?? I just want to connect the surace to the floor with a olor to make a cube
