@Izy724- AgentSmith has some terrific coral that he made using the Bryce Tree lab. I'd put up the link, but it's busted.:( Maybe he'll be kind enough to repost the settings for you. I think Wotan might have used a few clipmaps(2d pics)for the more intricate fan coral and brittlestars. Mounded coral is pretty easy to make by taking a coral texture off the net and applying it to a heightmap to make "coral" terrains. I used all the same techniques in an undersea pic based on sea life of the Ordovician era.
