    Hi all,
    I'm looking to create a shader which takes a normal map, but only darkens the texture and does not apply highlights, similar to a shadow map. Is there a simple way to do this? From what I've seen you either need to take a vector lightsource as input (which I'm not interested in as I'd like to have multiple/dynamic light sources) or write a bunch of custom code for lighting.
    I'm using pixel art and essentially want my art to 'pop' with lighting changes, but for this particular texture I'm not interested in highlights. I'm using URP.
    Thanks!

    Try setting the graph's workflow mode to Specular and then set the Smoothness to zero and the Specular Color to black. Does that get you what you're looking for?

    This brings me much closer to the effect I'm looking for. Thanks!
