I was wondering if there is a module somewhere that takes an image file and based on the shade of the pixel applies a kind of "sketch render" to the image making it look like a sketch.
If you're not sure what I mean, I am looking for something similar to what the Q3 mod that turned the entire game into a sketch. I was wondering if there is a module for this type of thing, and if not, is there a method I could read about so I could attempt to make my own?
Thanks for the help.
