I saw how 2DSprite turned into a gray image in the group last night. At night, it was most convenient to modify the shader.

The following is the implementation of the Sprites-Gray.shader, please put your own project:

Shader "Sprites/Gray"{Properties{    [PerRendererData] _MainTex ("Sprite Texture", 2D) = "white" {}    _Color ("Tint", Color) = (1,1,1,1)    [MaterialToggle] PixelSnap ("Pixel snap", Float) = 0}SubShader{    Tags    {         "Queue"="Transparent"         "IgnoreProjector"="True"         "RenderType"="Transparent"         "PreviewType"="Plane"        "CanUseSpriteAtlas"="True"    }    Cull Off    Lighting Off    ZWrite Off    Fog { Mode Off }    Blend One OneMinusSrcAlpha    Pass    {    CGPROGRAM        #pragma vertex vert        #pragma fragment frag        #pragma multi_compile DUMMY PIXELSNAP_ON        #include "UnityCG.cginc"        struct appdata_t        {            float4 vertex   : POSITION;            float4 color    : COLOR;            float2 texcoord : TEXCOORD0;        };        struct v2f        {            float4 vertex   : SV_POSITION;            fixed4 color    : COLOR;            half2 texcoord  : TEXCOORD0;        };        fixed4 _Color;        v2f vert(appdata_t IN)        {            v2f OUT;            OUT.vertex = mul(UNITY_MATRIX_MVP, IN.vertex);            OUT.texcoord = IN.texcoord;            OUT.color = IN.color * _Color;            #ifdef PIXELSNAP_ON            OUT.vertex = UnityPixelSnap (OUT.vertex);            #endif            return OUT;        }        sampler2D _MainTex;        fixed4 frag(v2f IN) : SV_Target        {            fixed4 c = tex2D(_MainTex, IN.texcoord) * IN.color;            c.rgb *= c.a;            float gray = dot(c.xyz, float3(0.299, 0.587, 0.114));            c.xyz = float3(gray, gray, gray);            return c;        }    ENDCG    }}}

Usage:

// Use this for initializationvoid Start () {    SpriteRenderer render = this.GetComponent<SpriteRenderer> ();    render.material.shader = Shader.Find ("Sprites/Gray");}
