I am simulating a beach. Having already modeled the terrain I created a
single mesh that defines both the beach and the submerged ground.

I have two questions:

-I then make use of the pfEarthSky clipping capacities to hide the
underwater part of the terrain when I'm not under water. Is the
underwater part of the mesh dealying the animation? Should I create two
separate objects (underwater and overwater) and switch between them?

-When moving underwater I have to simulate the water line above me (like
a ceiling). Unlike overwater I cannot use pfEarthSky to do the clipping
for me. I am planning on creating a biiig square that stands above my
head hiding the overwater terrain. Is there a better solution?

thanks
