I've used this tutorial to do a toon shader: https://www.youtube.com/watch?v=sJTEJKQ0lYw
But once I render it (Eevee), only the highlight appears.
Is there perhaps some kind of step I did wrong?
EDIT: If I add lightsources with a negative value, they'll throw a shadow even in rendered mode. However I don't understand why it doesnt work with a regular light source.
EDIT 2.0: Nevermind, with the negative lighting added it works in the Render Preview, but once actually rendered the shadows are gone again.
