If you create a model, and render a PNG with that model, the source for
the PNG is the model.  Okay, that's easy; we all probably agree here.

If I take your PNG, stick it in photoshop, edit it for a while, and save
that to a PNG, what's the source?  I'd say it's the PSD file or the PNG;
in any case, the model file is no longer relevant and isn't the source
at all.  (Your idea of "source"--even as the original author--isn't
relevant; my preferred form for modification, as the person actually
modifying, is what counts.)

I *think* you agree with the above, and this is just a more detailed
example of what we agree on, clarifying the question "which author/artist's
preferred form of modification?".
