I’m working on a version that uses params, so it will be easier to customize. I also changed the “edge detection by normals”, which was pretty bogus. I’ll post the file once I have it all hashed out. The pixel strobing might have been due to differences in the length of the pipeline for x+1,y x,y+1 vs. x-1,y x,y-1 pixel calculations, and 4.5.1 seems to have also improved the situation, so I’m no longer seeing parts of the outline flicker in extreme cases.
Also, one thing I need to mention, for the post-process, you need to reduce the ambient lighting (default is 1, should be 0.1 - 0.3) or the red facial shadows wash out and don’t really show up.
