I have found if you apply a ceil() function in the color reduction the dark scenes will appear to be more bright, thus making the edges more prominent. I also mix the original color with the quantized version, that result in a nice inbetween imo.

In this implementation i use the depth channel to slowly fade out the edges at the distance, but it not really a neccessity. If you just use the world normal (instead of the postprocess colour input), you won’t get any sobel edges on the skysphere anyways. Also, the sky in a toon environment could just be simply a gradient background, you don’t really have to use images of clouds and whatnot, therefore the edge will not disturb the background, and will appear to be more prominent in the foreground objects.

a desaturation of the colors is exactly the method i was thinking but i wasn’t sure of the result, thanks for the blueprint and video showcasing this way to do it, i also found that uncharted 4 cel shading method is kinda the same process, is the reason why i didn’t want to use the 3 bars of colors to make it, because it turns out to be not friendly with any others lights like spotlight for example

Uncharted 4: Cel Shaded Prison Fight

and once again, thanks for your help, i’m gonna credit you on my game

edit: oh well, it didn’t work blackout, i checked everything and it seems to be fine
