Unity shader，Zwrite On is not working. i cant see my object in scene

Question

I set ZWrite to On for my object in Unity's shader and set it to the Geometry render queue. However, this object is not visible in the Scene, and I can see through Frame Debug that the Zwrite for this object is off.

`Shader "Bump" { Properties { _MainTex("Main Texture", 2D) = "white" {}

}
SubShader {
    Tags { "RenderType"="Opaque" "RenderPipeline"="UniversalPipeline" "Queue"="Geometry" }

    HLSLINCLUDE
        #include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Core.hlsl"
        #include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Lighting.hlsl"

        CBUFFER_START(UnityPerMaterial)
        float4 _MainTex_ST;
        CBUFFER_END
    ENDHLSL

    Pass {
        Name "Example"
        Tags { "LightMode"="UniversalForward" }
        ZWrite On
        ZTest LEqual

        struct a2v{

            return OUT;
        }

        half4 frag(v2f IN) : SV_Target {
            float3 posWS = float3(IN.t2w0.w, IN.t2w1.w, IN.t2w2.w);
            float3x3 t2wMatrix = float3x3(IN.t2w0.xyz, IN.t2w1.xyz, IN.t2w2.xyz);
            Light light = GetMainLight();
            half3 lightDirWS = normalize(light.direction);
            half3 viewDirWs = normalize(_WorldSpaceCameraPos.xyz - posWS);
            half3 halfDirWs = normalize(lightDirWS + viewDirWs);

            half4 baseMap = tex2D(_MainTex, uv);
            half3 finalColor = baseMap.rgb;

            
            return half4(finalColor, 1);
        }
        
        ENDHLSL
    }
}

how can i make object in geometry queue visible in scene.

Answer 1

Your shader has error at line this line:

half4 baseMap = tex2D(_MainTex, uv);

It should be IN.uv. You have wrongly entered just uv.
