I’m extremely new to shaders, after finding a tutorial which modified a surface shader the object was invisible, I originally thought this might be due to a possible different pipeline or the tutorial being wrong/outdated but after creating a default surface shader without modifying it and applied it was still invisible.
Tutorial’s Code
Shader "Holistic/HelloShader" {
Properties {
_myColour ("Example Colour", Color) = (1,1,1,1)
_myEmission ("Example Emission", Color) = (1,1,1,1)
}
SubShader {
CGPROGRAM
#pragma surface surf Lambert
struct Input {
float2 uvMainTex;
};
fixed4 _myColour;
fixed4 _myEmission;
void surf (Input IN, inout SurfaceOutput o){
o.Albedo = _myColour.rgb;
o.Emission = _myEmission.rgb;
}
ENDCG
}
FallBack "Diffuse"
}
Default Shader Code
Shader "Custom/NewSurfaceShader"
{
Properties
{
_Color ("Color", Color) = (1,1,1,1)
_MainTex ("Albedo (RGB)", 2D) = "white" {}
_Glossiness ("Smoothness", Range(0,1)) = 0.5
_Metallic ("Metallic", Range(0,1)) = 0.0
}
SubShader
{
Tags { "RenderType"="Opaque" }
LOD 200
CGPROGRAM
// Physically based Standard lighting model, and enable shadows on all light types
#pragma surface surf Standard fullforwardshadows
// Use shader model 3.0 target, to get nicer looking lighting
#pragma target 3.0
sampler2D _MainTex;
struct Input
{
float2 uv_MainTex;
};
half _Glossiness;
half _Metallic;
fixed4 _Color;
// Add instancing support for this shader. You need to check 'Enable Instancing' on materials that use the shader.
// See https://docs.unity3d.com/Manual/GPUInstancing.html for more information about instancing.
// #pragma instancing_options assumeuniformscaling
UNITY_INSTANCING_BUFFER_START(Props)
// put more per-instance properties here
UNITY_INSTANCING_BUFFER_END(Props)
void surf (Input IN, inout SurfaceOutputStandard o)
{
// Albedo comes from a texture tinted by color
fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * _Color;
o.Albedo = c.rgb;
// Metallic and smoothness come from slider variables
o.Metallic = _Metallic;
o.Smoothness = _Glossiness;
o.Alpha = c.a;
}
ENDCG
}
FallBack "Diffuse"
}
