I don't know about NPR, but one thing to consider is that in Carrara,
unless the object is specifically a volumetric object, all objects are
simply shells of zero thickness. You can go directly into a sphere
from the outside, and once inside, you will see the shader (unless
you've taken steps to prevent this) that's on the outside.
This might be one of your problems. Another possibility for you to
try is to work around this, stopping a fraction short of the object,
then editing in a direct cut to black (video editing program). This
would work as well, I think.
