Hey, I’m trying to have the Toon Lighted Shader increase/decrease the size of the ramp depending on the main light’s intensity. Any ideas how I’d go about this? I’m considering changing the line below to multiply by something, but I’m not sure what.
half d = dot (s.Normal, lightDir)*0.5 + 0.5;
^ This line because when I mess with the 0.5 numbers, it increases/decreases the ramp size.
Shader "Toon/Lighted" {
Properties {
_Color ("Main Color", Color) = (0.5,0.5,0.5,1)
_MainTex ("Base (RGB)", 2D) = "white" {}
_Ramp ("Toon Ramp (RGB)", 2D) = "gray" {}
}
SubShader {
Tags {"Queue"="Transparent" "RenderType"="Transparent"}
Blend SrcAlpha OneMinusSrcAlpha
LOD 200
CGPROGRAM
#pragma surface surf ToonRamp
sampler2D _Ramp;
// custom lighting function that uses a texture ramp based
// on angle between light direction and normal
#pragma lighting ToonRamp exclude_path:prepass
inline half4 LightingToonRamp (SurfaceOutput s, half3 lightDir, half atten)
{
#ifndef USING_DIRECTIONAL_LIGHT
lightDir = normalize(lightDir);
#endif
half d = dot (s.Normal, lightDir)*0.5 + 0.5;
half3 ramp = tex2D (_Ramp, float2(d,d)).rgb;
half4 c;
c.rgb = s.Albedo * _LightColor0.rgb * ramp * (atten * 2);
c.a = s.Alpha;
return c;
}
sampler2D _MainTex;
float4 _Color;
struct Input {
float2 uv_MainTex : TEXCOORD0;
};
void surf (Input IN, inout SurfaceOutput o) {
half4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color;
o.Albedo = c.rgb;
o.Alpha = c.a;
}
