Welcome to Mankini Bay! The main rock is just some random geometry 'rock-a-lated' slightly in Zbrush as that's about my limit in that program. And yes, I made that word up. The trees (apart from the big one), are billboards – rendered out a collection of palm leaves from the tree lab and added curvy trunks in Paint.net and brought them back into Bryce as a 2D image. Birds are also billboards of a random photo of a flock of birds. Everything else is Bryce. No postwork. Grass skirts and Bermuda shorts optional...
