Awesome thanks for the feedback! In regards to the clouds, I agree I think it could get to be a bit much for realtime applications, but my focus is on using Unity for rendering. So dense forests, and high resolutions clouds wouldn't be a concern. But I think that adding in the ability to capture the sky you create and out put it to a skybox would be beneficial. Lots of things on the horizon Regarding the rocks, again it just comes down to crafting that perfect shot. Being able to dive into a library of rock assets to let you create a photoreal gravel path, to a cliff wall, to a distant mountain would be nice to have.
