Bagginsbill, a couple of followup questions:

1)  How do I setup a new template material so that it will use the existing image maps in my new shader tree?  (I have read the PDF on the VSS Home Page but it wasn't clear to me).  Here is the situation:  I'm working with a non-human figure (a building) and I need to replace the supplied shader tree(s) with correct shader tree(s) (for gamma correction, conservation of energy, etc - all the fun things you teach us about here).  I'm missing how to set up the image map(s) in my shader so it will take the specific ones from the existing shader.

2. Will VSS also copy constants from the poser surface node in the template to the target or does it only deal with nodes plugged into the poser surface node?  In the building I'm working with, the ambient value on all of the shaders is set to 1 (with a color of black so it's still a no-op).  I would prefer that the ambient value is 0 and the color is set to white.  If I set that up in the template shader will it copy that to the targets?

Thanks in advance.
