Object Using Shader That Should Always Show Up Dissapears When Behind Some Objects

To Repro; when an object with this shader on is below the terrain, or behind some objects, it will sometimes dissapear. it almost feels like it shows up for 2 seconds while moving ,then dissapears, and does so with some regularity. What can i add to this shader to make sure it will always show up?

Thanks.

Render queue is set to 4001

Code (CSharp):

1. Shader "Custom/AlwaysShowUp"
2. {
3.     Properties
4.     {
5.         _MainTex ("Texture", 2D) = "white" {}
6.         _Color("Always visible color", Color) = (0,0,0,0)
7.     }
8.     SubShader
9.     {
10.         Tags { "Queue"="Overlay+2" }
11.         LOD 100
12.  
13.         Pass{
14.             Cull Off
15.             ZWrite Off
16.             Lighting Off
17.             ZTest Always
18.  
19.             CGPROGRAM
20.             #pragma vertex vert
21.             #pragma fragment frag
22.  
23.             #include "UnityCG.cginc"
24.            
25.             struct appdata
26.             {
27.                 float4 vertex : POSITION;
28.                 float2 uv : TEXCOORD0;
29.             };
30.  
31.             struct v2f
32.             {
33.                 float2 uv : TEXCOORD0;
34.                 float4 vertex : SV_POSITION;
35.             };
36.  
37.             float4 _Color;
38.  
39.             v2f vert(appdata v)
40.             {
41.                 v2f o;
42.                 o.vertex = UnityObjectToClipPos(v.vertex);
43.                 return o;
44.             }
45.  
46.             fixed4 frag(v2f i) : SV_Target
47.             {
48.                 return _Color;
49.             }
50.  
51.             ENDCG
52.         }
53.     }
54. }
55.  

 

Sounds like occlusion culling is causing the object to simply not get rendered. Nothing you can really do from the shader side of things. The easiest solution would be to increase the bounds of the mesh to something ridiculous, or disable dynamic occlusion if it’s a mesh renderer.

 

Thank you, i never had thought to disable dynamic occlusion, turning that off resolved my issue.
