Quote - face_off's script was more specific than Matmatic, that's all.  Matmatic is just a programmatic interface.  it is entirely possible to make light specific shaders with Matmatic.  if one isn't careful about one's initial suppositions, one could easily find oneself making completely light specific shaders.  face_off knew his shaders were light specific, and made a script to account for that.  anyone else will have to do rigorous testing to make sure their shaders are not actually light dependent.  just by eyeballing, i'd say most i've used are, and either work in very light settings, very dark settings, or very extreme settings.  very, very, very few actually work independent of lighting.

I suppose I wasn't clear about what I was hoping to accomplish. I realize that Face_off's realism kit is light-position/intensity/colour/etc-specific, so there would be no way for me to predict that. However, face_off also added textures like spots and freckles that Matmatic seems to be able to do as well. Upon reflection, however, I really shouldn't be using face_off's tool as an example of what I wish to accomplish, since it's much more an end-user tool rather than a development tool (to a point).

I guess what I need to say at this point is: I see Matmatic merely as a programmatic node-management tool. You still have to set the parameters of the shaders yourself. Matmatic simply gave you a programming means of accomplishing that, and over as much of the object and addressing as many materials as needed or desired.
