Cell Shading Using 2D Renderer?

Questions & Answers

Hi!
I’ve been messing around with ShaderLab and ShaderGraph, trying to make a 2D Cell/Toon Shader, that replicate the one in Laigter. (awesome software btw)

Where I’m at:

Currently I have a working hlsl shader, that with a few alterations using the unity template, I was able to render the effect with some wild, but good results.

The code below is a snippet of what I am doing in the fragment shader responsible for the normal map:

Objective:

Now I was hoping to be able to do the same effect in shader graph, mostly for iteration reasons.
Shortly, I am looking for this using 2D lights (and without fresnel). aka this

For what I understand the custom node in the 6 above (see below) doesn’t work for 2D lights, I was wondering if there’s is a replacement function for GetMainLight(0) or something.

#ifndef CUSTOM_LIGHTING_INCLUDED
    #define CUSTOM_LIGHTING_INCLUDED

    void CalculateMainLight_float(float3 WorldPos, out float3 Direction, out float3 Color) 
    {
        #if defined(SHADERGRAPH_PREVIEW)
            Direction = float3(0.5, 0.5, 0);
            Color = 1;
        #else
            Light mainLight = GetMainLight(0);
            Direction = -mainLight.direction;
            Color = mainLight.color;
        #endif
    }

#endif

I will also leave some links that were useful during my research:

Thanks! :smiley:

Hey! @luistorres_emvenci - any luck? did you happen to solve it or find a workaround somehow?
