NPR style renderings

[bob-designer]

Hi All,
Would someone please direct me to information on how to create NPR renderings.
I am having trouble getting my brain around the subject. Thanks, Bob

Piranesi or just export the raw SU image and run it thru FotoSketcher

Is there some specific NPR style you're trying to emulate? There are tutorials out there but your request is a bit vague.
