I agree with those above. One of the hatdest things i have tried to do in bryce was forming waves for a rough sea. The sea you see in this image was done using a terrain which fortunately for me one of the kind artist on this forum sent to me. I just raised the waves a bit then duplicated it and used a water mat which i tweak to form the whites of the waves...By the way this image is still being worked on because i'm just not happy with it yet :)

I have opinions of my own -- strong opinions -- but I don't always agree with them.
