Does anyone have a good suggestion on how to animate growing roots in LW? This means that I would animate one root growing and also have some of the root branches animating from the main root. Any thoughts?

Theres a few methods:
Heres one using HVs:

This example using a texture driven endomorph

and then theres the fertilizer plugin:

That is terrific, Larry! Thank you so much. I will give these a try.

That is interesting....So if I understand you correctly,
1. A full tree model with roots is created
2. A UV is created for the tree (and roots of course)
3. Using the UVMorph - Normal Displacement Morph(I'm not familiar with that but I will look it up), the geometry animates .

Now you mentioned an bw animation for a map. How would that work?

yes, basically,
you will have to make an actual morph for the Normal Displacement Morph to use though.

don't have the time now, might test it later on.
but the bw animation can be done as a videofile, or simply just adjusting the opacity of the bw texture.

it's a bit big project to take on, but so are all cool projects ;)

I would do that with SG_Fertilizer (http://www2.informatik.hu-berlin.de/~goetsch/Fertilizer2/). Model the root object as usual, define the starting point with weightmap, then animate SG_Fertilizer progress envelope, it is so easy. Try it.

Generally I use a couple of methods...
You can apply a blank image on a UV map. Apply the textured filter plugin in the image editor to the blank image. This allows you to use a procedural or other textures on top of your blank image to activate the morph.
You can also use Gradients using referece nulls (distance to object).
You can also use a 2d animation program like PDPro. Ill take the UV template into that and do a simple animation with white on black on top of the UVs. Ill export that as an avi and use it to drive the morph.
