Thank you very much!
Indeed the texturing turned out to be more complex than expected.
Additionally I noticed that on different monitors the pics look quite
different from mine. Obviously has my monitor a bit dark overall brightness
(drakness :-) ) and a pretty strong gamma setting. I played a bit with the
assumed_gamma settings but didn't really put much effort in it yet.
Especially for the last picture you are right: it looks a bit plastic. This
is due to the focal_blur which removes the small reflections caused by small
ripples of the leaf. Instead of the detail it creates larger, unsharp
highlight areas which give this plastic look (beside the too dark greenish
colour). I want to use focal blur in the final image but in a smaller scale.
The final image will have only one or two "wings" of the fern and not the
whole thing.
> Nothing important for your great modelling effort, tough.
I think it IS important. A good modelling can be destroyed easily with a
wrong texture. I am aware of one major defect of the leaves which also
explaines why real leaves are more yellowish:
The leaves are not transparent. A real leaf of a fern acts like a emitting
media if lightened from the background. Like a milky glass it emits light
but you can't see through it. In case of this back-lighting it is almost
yellowish. I tried to emulate this but I failed. The results were always a
transparent thing (through which you could see the leaves usually hidden by
others) or it didn't emit light or it -always- emitted light independently
og the lighting situation.
Anyway, I will have to change the texture. The difficult thing is that the
colour is computed according to the leave's age. I have to model new
formulas....
regards,
SY
