A few months ago I posted a tutorial on how to make realistic looking fall trees in Vue. Well I've been fine tuning the process and have now come up with a color function which basically does the same thing in the tutorial but this is much easier to use. It uses three main colors and a combiner or blender node to mix them. You can change the colors of the tree by changing the three colors around and you can vary the degree of mixing by using the threshold sliders. I've used it on the standard trees that came with V5I and with Oynx Tree Pro. Should work with others but I'm not sure. I uploaded it to the free stuff section but it's also on my home page as well.
A little belated Christmas gift to everyone :)
