Wonderful work. My first idea of a slight improvement is to have some yellowish
leafs between the green and the brown ones, since most green leafs are turning
yellow before turning red or brown. But this remark should not belittle your
approach, it's wonderful. During my daily travels by train to work and back I
had to pass some woods and pondered this issue again and again and ever thought
to break down the arbaro meshes in leaf groups to achieve this. Your approach is
much more simple and seems to work fine.
Best regards,
Michael

Thanks Michael! Yellow leaves should not be too difficult in the present
configuration: just an intermediate pigment between green and red, and
some more tweaking on the texture_map. I have only explored a little of
the uv-mapping part of POVtree and that is where I want to try this
technique out too, one way or another. For instanc,e I was thinking
about layering the colours over the leaf image_maps, although that might
give unexpected results.
I am not too familiar with arbaro although it is gathering dust
somewhere on my HD ;-) For each application the approach might be different.

Something like this.

Sorry for answering a little bit late, but I'm heavily occupied by RL issues at
the moment (and will be till the end of the year - as every year). Yes,
something like this (to cite Kevin Kline in "A Fish called Wanda"). It's fine. I
hope to find time next year to have some experiments with this
scaling-turbulence trick.
Best regards,
Michael

That's all right. I have continued my investigations a bit:
Problem: POVtree does not export to mesh{} with uv-mapped leaves. There
is a bug in the program. A pity Gena disappeared from the web. :-( so my
idea to experiment with that comes to naught.
I am looking into Arbaro right now.

further, otherwise it would've ended like so much other trials and errors...
Good luck for you,

Yes, this is looking quite perfect to me.
I have not yet found a good way (for me) to tackle the uv-mapped
image_map leaves.I am investigating.

These are nice. They're making me nostalgic for my years in New England.

Using my simple spherical technique seems not to be so straightforward
as I initially thought.
Here I use it on a modified Arbaro tree with wider spaced branches. The
result is less than natural looking to me, although pretty.
