Imho looking much better now. Personally I'd shift the leafs albedo hue more towards yellowish. This still looks a tad too chemical :)
Just a question - how many individual leaf ID's there are per tree ? Asking because some leaf variations would be welcome.
Bluebox, thanks for your inputs, we really appreciate it :-)
You were right about the variations, so we first of all re-did the leaf materials, as well as added additional textures for more variations up close, and added an instanced multimap for the overall color variations. There is a huge difference!
This preview is straight from the frame buffer and without displacement. You think we're on the right track? ;-)
