Shader Slider

Archived Forums Questions & Answers

So I am trying to add some sliders to have more control over my shaders for each different mesh. I’m adding them to the Toon/Lighted Shader so I can control the ramp sizes.

For some reason though, it’s giving me an error saying that the variables do not exist. I put them there, so I’m not sure why it can’t access them. I am using Toon/Lighted Outline as the actual Shader, but I know the lighting is affected from this one. Could someone tell me whats up?

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" {} 
		
		_LightSize ("Light Size", Range (0, 1)) = 0.75
		_MidSize ("Mid Size", Range (0, 1)) = 0.75
		_DarkSize ("Dark Size", Range (0, 1)) = 0.25
	}

	SubShader {
		Tags { "RenderType"="Opaque" }
		LOD 200
		
CGPROGRAM
#pragma surface surf ToonRamp

sampler2D _Ramp;

#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)*_LightSize + _MidSize + _DarkSize;
	half3 ramp = tex2D (_Ramp, float2(d,d)).rgb;
	
	half4 c;
	c.rgb = s.Albedo * _LightColor0.rgb * ramp * (atten * 2);
	c.a = 0;
	return c;
}

The error message is an unhelpful lie; it just means that your shader has errors.

The Inspector sprays them at you, hiding the original error, way up on top, which at least gives you a line number. Your _darkSize lines near the top say to create a slider for _darkSize in the Inspector, but you never actually create a darksize. Notice how _Ramp is also declared down below. Toss in float _Darksize, _MidSize ... and it should work (or comment out a bunch and just try adding 1 darkSize by itself.)

That worked, Owen. Thank you very much :).

It is working. No idea about the memory efficiency, but I never encountered any hiccups.

That's not an answer. Don't use an answer for a question, instead add a comment on the post your question is from.
