Hi all,
I made some tests. I used the Hdtrees leaves because they had some bump and reflection maps.
I have to tweak the saturation a bit. The leave are still a bit oversaturated in my opinion.
The leaves could be a bit more translucent too. But with every test they looked very dull. Also the amount of translucency depends on the different scenes (distance, light setup, color of the context, etc.). This is my middle of the road setup.
Also I have to alter the shape of the leave a bit and swap it in Atree3d model. It doens't match these bitmaps nicely.
I added my material setup. Nothing fancy, just simple setup.
It has still a lot of color correction maps included. These are not necessary of course.
