Question This stencil shader won't compile

When I build the shader will not compile and I don't know why.

When I run the build the stencil write shader has missing game objects behind it.

My build works correctly when I remove the shader.

From ronja-tutorials.

Code (CSharp):

1. Shader "Tutorial/022_stencil_buffer/write"{
2.     //show values to edit in inspector
3.     Properties{
4.         [IntRange] _StencilRef ("Stencil Reference Value", Range(0,255)) = 0
5.     }
6.  
7.     SubShader{
8.         //the material is completely non-transparent and is rendered at the same time as the other opaque geometry
9.         Tags{ "RenderType"="Opaque" "Queue"="Geometry-1"}
10.  
11.         //stencil operation
12.         Stencil{
13.             Ref [_StencilRef]
14.             Comp Always
15.             Pass Replace
16.         }
17.  
18.         Pass{
19.             //don't draw color or depth
20.             Blend Zero One
21.             ZWrite Off
22.  
23.             CGPROGRAM
24.             #include "UnityCG.cginc"
25.  
26.             #pragma vertex vert
27.             #pragma fragment frag
28.  
29.             struct appdata{
30.                 float4 vertex : POSITION;
31.             };
32.  
33.             struct v2f{
34.                 float4 position : SV_POSITION;
35.             };
36.  
37.             v2f vert(appdata v){
38.                 v2f o;
39.                 //calculate the position in clip space to render the object
40.                 o.position = UnityObjectToClipPos(v.vertex);
41.                 return o;
42.             }
43.  
44.             fixed4 frag(v2f i) : SV_TARGET{
45.                 return 0;
46.             }
47.  
48.             ENDCG
49.         }
50.     }
51. }

 

It compiles now, but build still has problems.

When I test the shader with a FBX imported game map it does not work.

The shader only works with quads.

The FBX import has read/write enabled.

There is a problem with this shader and the FBX file.

Maybe this is a bug?

 

The shader works with quads made in Unity.

The FBX imported file is not working for some reason.
