Played around with Vizcom's S2R AI shading tool. Supply a drawing, it uses AI to do the shading in 1 click. First image is a rough pen drawing and the 1 click results. Image 2 is the result with 2 min of extra hand paint. Image 3 is another robot head test. And the final image is trying it on something flatter. The AI seems to work best on rounded surfaces, maybe because it trained on a lot of car sketches? Still, some neat results with a more rectilinear spaceship.
