Unity 對象顏色梯形漸變Shader，可調節

1.代碼如下(這個無外發光)：

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

首先謝謝大家的支持，其次如果你碰到什麼其他問題的話，歡迎來 我自己的一個 討論羣559666429來(掃掃下面二維碼或者點擊羣鏈接 Unity3D[ 交流&副業]CLUB ),大家一起找答案，共同進步。 同時歡迎各大需求商入住，發佈自己的需求，給羣內夥伴提供副職，賺取外快。對了，資源的話，要在羣公告裏面找。

由於工作生活太忙了，對於大家的幫助時間已經沒有之前那麼充裕了。如果有志同道合的朋友，可以接受無償的幫助別人，可以單獨聯繫我，一塊經營一下。
如果你有更好的經營方式也來練習我，加我QQ
