Thanks, that's now sorted.

As I said, and have now done. I added an if() statement to the sand iso so
that the RMF pertubations are about 5 times less bumpy below the water level
than they are above it. i.e

function {
    y
    +0.07*if(-z,-z,1) // Sloping off in -z direction
    -35*Func2(x/400,y/200,z/400) // Overall Shape
    -1.9*Func2(x/30,y/30,z/30)*if(y+6,1,0.2) // Less bumpy below water line
}

actually the

+0.07*if(-z,-z,1)

should probably be

+0.07*if(-z,-z,min(z,1)) ,

I'll have to check this one now. That first one should create a problem at
z=0, but then again so should the other one at y=6. Oh well, they seem to
work ok :)
