Unity 对象颜色梯形渐变Shader，可调节

1.代码如下(这个无外发光)：

Shader "MyShader/LinearGradientsNoLight" {    Properties    {        [HideInInspector] __dirty("", Int) = 1        _Soften("Soften", Range(0.1 , 10)) = 1.092425        _MainValue("MainValue", Range(-10 , 10)) = -0.0336646        _Brightness("Brightness", Range(0 , 1)) = 0.2873606        _GroundColor("GroundColor", Color) = (0.9448276,0,1,0)        _UpperColor("UpperColor", Color) = (1,1,1,0)    }        SubShader    {        Tags{ "RenderType" = "Opaque"  "Queue" = "Geometry+0" "IgnoreProjector" = "True" }        Cull Back        CGPROGRAM#include "UnityShaderVariables.cginc"#pragma target 3.0#pragma multi_compile_instancing#pragma surface surf Standard keepalpha addshadow fullforwardshadows         struct Input    {        float3 worldPos;    };    uniform float _MainValue;    uniform float _Soften;    uniform float _Brightness;    UNITY_INSTANCING_CBUFFER_START(MyShaderTestShader)        UNITY_DEFINE_INSTANCED_PROP(float4, _GroundColor)        UNITY_DEFINE_INSTANCED_PROP(float4, _UpperColor)        UNITY_INSTANCING_CBUFFER_END        void surf(Input i , inout SurfaceOutputStandard o)    {        float4 _GroundColor_Instance = UNITY_ACCESS_INSTANCED_PROP(_GroundColor);        float4 _UpperColor_Instance = UNITY_ACCESS_INSTANCED_PROP(_UpperColor);        float3 ase_vertex3Pos = mul(unity_WorldToObject, float4(i.worldPos , 1));        float clampResult55 = clamp(saturate(((ase_vertex3Pos.y + _MainValue) / _Soften)) , _Brightness , 1.0);        float4 lerpResult61 = lerp(_GroundColor_Instance , _UpperColor_Instance , clampResult55);        o.Albedo = lerpResult61.rgb;        o.Alpha = 1;    }    ENDCG    }        Fallback "Diffuse"        CustomEditor "ASEMaterialInspector"}
