thank you for your time and willingness to share knowledge.....
i am trying to create a certain effect to a human body
like the electrical spikes in this image

my aproach is to make a toon outline to the body
then convert this "paint effects toon" into a nurb surface so i can add fur to it
when i do this.... the hands are much to full of the fur and his arms to less
aswell his eyes and ears recieve a toon line that i find not nescasary....

i tried creating abody with a complete fur on its skin and then use a facing ratio to only make visible the outer circumference of the body
but this with no acceptable result
i only need the effect around the body when i fly around it with the camera
does anyone has some clues for me to achieve this effect
thank you for your time.....
