How can I randomly adjust the hue of objects in a population (actually, parts of objects-- say, the leaves of a tree)?  For example, how can I randomly change the hue of leaves on a tree so the hues range from red to yellow to orange, etc.?

Thanks!

You can use power fractal shaders to adjust the colours in many ways.

If you wanted the leaves to be green, but retain some of the UV texture data, you can load the texture as  a Image Map Shader, than use the Convert Colour to Grayscale. From here, you can use a Add Colour shader and a PF to add new colour definition to the grayscale image map.

I'll post an example in a moment. I just realize I have no vegetation objects (again) due to various issues I had migrating to a new PC with a Seagate 2tb (Don't trust Seagate with valuable data, seriously)

Just because milk is white doesn't mean that clouds are made of milk.

Here's an example of procedurally recolouring a texture image, in this case the Japanese Walnut from Xfrog: http://xfrog.com/product/JA08.html (note, this [TGO] object is old, and it's network may appear unfamiliar)
