  I posted a tutorial on making leaves with height fields in the
binaries.tutorials group probably about 9 months ago. It is easy
to do if you have a leaf photograph to work from. There is a web
page that has plant and pollen pics that you could probably get
your pics fron then use my tutorial to get you started for very
realistic looking leaves.

Try both of these sites:

I use greyscale bump maps made from real images of bark and then use
the original full colored image on top of the bum map for the color.
Work good but finding bark images takes a while. You might find some
useful images at the above two sites.


One last suggestion I have is Tree Designer which has a nice suite
of pre-made leaves and is designed for modelling trees. I believe
Mr. Hubert also uses HF's to make leaves for his modeller. Check
it out at:
