i've read the notes (very nicely structured information, i must say) at http://www.users.on.net/~pkinnane/ShaderComparison.html and i'm still curious about how the different products interrelate. If you have, say, HyperReal V3, is it still useful to get the Unimesh Realism Kit? If someone gets the new GI Jill, would a Kit still be helpful? Basically, are the non-texture map features largely the same, and if not, what are the particular features specific to each one (outside Poser version compatibility and uv map specificity)?
