Here's a quick little WIP; more of a "proof of concept" render. I plan to make the canyon wider, add some stair-step type rapids, snags(fallen trees and branches) lots more distant trees and vegetation, and a raft full of people. The rock texture is the first one that I totally made by scratch. I added a slope operator with a little green gradient and I liked the "mossy" sort of look it seemed to add. I've had Carrara5 for almost a year now (March) and I'm just now starting to come to terms with the shader room. I want to get the DCG Terrain Tools plug next so I can experiment with trying to get some froth or spray effects. I'd also like to see if I can use it to try to add a band of wet looking rock just above the river.
