Hello, my paintings aren’t effected by the light, so it has always the same colour. It looks weird when some parts have no shadows, as you can see on the left cheek and the eyes. How can I add them, so it gets darker when the light is not shining on it ?
You’re doing cell shading. The whole point of your node setup is to quantize the lighting: to make it exist at only two intensities. If you don’t want cell shading, don’t use your color ramp. Make your diffuse pink and skip the color ramp. (Or else, edit your color ramp to give yourself more levels of lighting, possibly without constant interpolation between colors.)
Oh, I wasn’t looking closely enough at what you were doing with your image texture (which doesn’t make a lot of sense, BTW.) What does your “Untitled” image look like? What I would do is replace whatever’s transparent in that texture with pink, change your color ramp to grayscale rather than colored, disconnect the alpha from mix fac and set the fac to 1, and set the mix mode to multiply.
