I'm quite new to Blender, but I created this little illustration based off Brian Michael Gossett's work to practice my skills. Quite happy with the progress, but the problem is that the shadows are actually fake. They're just black meshes positioned right below every single object to make it look real. I was wondering if it's possible to actually create real hard shadows in Eevee as such, so that I can also animate this illustration. Does anyone know? If so, how?
In EEVEE, you can toonify as much as you like by using the Shader to RGB node, and passing the resulting color through a threshold:
Here, the floor-plane receiving the shadow has the material shown... original shadows, in this case, soft, and hardened in the color ramp.
The background curve is just the natural fade of a Sun lamp by reflected angle, caught at a certain level of grey by the threshold.
