Sprite Always over Meshes

I tried to change the sorting layer of my mesh,but the sprite it's always render under the meshes how can i do?

 

Try changing the Z-Value, this is technically (render depth). One is most likely higher than the other.

 

I tried ,but my camera is in prospective , i know i can do it with camera ,but i want to try something easy

 

Can you give a bit more details on your exact problem?

 

The arrow is a Sprite, but the Y value is the same like the floor and i want the arrow rendered always over the floor or other objects
here you can che the problem and what i want

 

Solve it with a simple Shader Code

Code (CSharp):

1. Shader "Custom/SpriteOverlay" {
2.        Properties
3.     {
4.         [PerRendererData] _MainTex ("Sprite Texture", 2D) = "white" {}
5.         _Color ("Tint", Color) = (1,1,1,1)
6.         [MaterialToggle] PixelSnap ("Pixel snap", Float) = 0
7.     }
8.  
9.     SubShader
10.     {
11.         Tags
12.         {
13.             "Queue"="Transparent"
14.             "IgnoreProjector"="True"
15.             "RenderType"="Transparent"
16.             "PreviewType"="Plane"
17.             "CanUseSpriteAtlas"="True"
18.         }
19.        
20.         ZTest Always
21.         Cull Off
22.         Lighting Off
23.         ZWrite On
24.         Fog { Mode Off }
25.         Blend One OneMinusSrcAlpha
26.  
27.         Pass
28.         {
29.         CGPROGRAM
30.             #pragma vertex vert
31.             #pragma fragment frag
32.             #pragma multi_compile DUMMY PIXELSNAP_ON
33.             #include "UnityCG.cginc"
34.  
35.             struct appdata_t
36.             {
37.                 float4 vertex   : POSITION;
38.                 float4 color    : COLOR;
39.                 float2 texcoord : TEXCOORD0;
40.             };
41.  
42.             struct v2f
43.             {
44.                 float4 vertex   : SV_POSITION;
45.                 fixed4 color    : COLOR;
46.                 half2 texcoord  : TEXCOORD0;
47.             };
48.  
49.             fixed4 _Color;
50.  
51.             v2f vert(appdata_t IN)
52.             {
53.                 v2f OUT;
54.                 OUT.vertex = mul(UNITY_MATRIX_MVP, IN.vertex);
55.                 OUT.texcoord = IN.texcoord;
56.                 OUT.color = IN.color * _Color;
57.                 #ifdef PIXELSNAP_ON
58.                 OUT.vertex = UnityPixelSnap (OUT.vertex);
59.                 #endif
60.  
61.                 return OUT;
62.             }
63.  
64.             sampler2D _MainTex;
65.  
66.             fixed4 frag(v2f IN) : SV_Target
67.             {
68.                 fixed4 c = tex2D(_MainTex, IN.texcoord) * IN.color;
69.                 c.rgb *= c.a;
70.                 return c;
71.             }
72.         ENDCG
73.         }
74.     }
75. }
