by the way - as I said, the tgo setup is pretty basic so far. I think you can imrpvoe the look by:
-finetuning displacement on leaves
-probably by using the spec or displacement map to improve the look of translucency
-work a little bit on the speculars
In the Cinema version I used a setupt with two sided leaves - upper side a darker, more reflective green, down side brighter, desaturated and dull. Two sided setupt would be nice in TG too...
