Hi, I am currently trying to render large trees in POV-Ray. I have attached an
image of a prototype scene so you can see what I mean. The scene used was
created by Gilles Tran and is available here:
http://www.oyonale.com/modeles.php?lang=en&page=38

I have just replaced his tree with one of mine.

The issue I am having is that with so many leaves light does not propagate into
the crown of the tree. In the picture I have posted I used a %50 transparent
leaf texture which helps a little but also blurs everything and would look bad
for close up shots.

What I am looking for is a way to make a texture that allows light to pass
through it while not having the object transparent.

Does anyone know how to do this in POV-Ray?

Thanks
-Steve
