How to add lighting in a unlit shader graph?

Hello! :blush: I’m having some trouble adding lighting effects to an Unlit shader in Unity Shader Graph. Could someone help me with that?

I’m trying to achieve a visual style similar to Plastiboo’s artwork.

So far, I created a placeholder texture and applied a palette filter shader to it. The next step is to add lighting interaction, so I can get darker areas in the dungeon, reacting properly to scene lights.

I tried using a lighting setup I found in a Reddit post, but it always creates a point light effect at the center of the plane, even though there’s no actual light object there.

What I really want is for the texture to remain unlit (to preserve the palette effect), but still have the real scene lights (point lights, spotlights, etc.) affect the shading—adding shadows and darker zones based on light positions.

Does anyone know how I can make my Unlit Shader Graph texture react to real Unity lights?

Thanks in advance! :grinning_face_with_smiling_eyes:

Creating your own lighting model is quite a large topic with a lot of information to cover. I have created a series of YouTube videos that go over that information here:

I hope they’re helpful.
