+# Write a depth-only pass in a Universal Render Pipeline shader
+
+To create a depth prepass that writes the depth of objects before the opaque and transparent passes, add a shader pass that has the `DepthOnly` tag.
+
+Add this pass if you enable a setting that requires a depth prepass, otherwise Unity might render incorrectly. For example, if you enable **Depth Priming** in the [Universal Render Pipleine (URP) Asset](urp-universal-renderer.md), opaque objects are invisible.
+
+**Important**: To render correctly, make sure that every shader pass renders the same number of fragments in the same positions. For example, use an include or a macro to share the same code between passes, especially if you change the positions of vertices, use alpha clipping, or use effects like dithering. 
+
+## Add a depth-only pass
+
+The following example shows how to add a depth-only pass to a shader:
+
+```lang-hlsl
+Shader "Example/CustomShader"
+{
+    SubShader
+    {
+
+        Tags { "RenderType" = "Opaque" "RenderPipeline" = "UniversalPipeline" }
+
+        // Add a depth-only pass
+        Pass
+        {
+            Name "DepthOnlyPass"
+            Tags { "LightMode" = "DepthOnly" }
+
+            // Write depth to the depth buffer
+            ZWrite On
+
+            // Don't write to the color buffer
+            ColorMask 0 
+
+            ...
+        }
+
+        // The forward pass. This pass also writes depth by default.
+        Pass
+        {
+            Name "ForwardPass"
+            Tags { "LightMode" = "UniversalForward" }
+
+            ...
+        }
+    }
+}
+```
+
+## Add a depth and normals pass
+
+The recommended best practice is to also add a pass that has the `DepthNormals` tag, to write both the depth and normals of objects. Otherwise, if you enable features like screen space ambient occlusion (SSAO), Unity might not render objects correctly.
+
+For more information about outputting normals, refer to [Visualize normal vectors in a shader in URP](writing-shaders-urp-unlit-normals.md).
+
+For example:
+
+```lang-hlsl
+Pass
+{
+    Name "DepthNormalsPass"
+    Tags { "LightMode" = "DepthNormals" }
+
+    // Write depth to the depth buffer
+    ZWrite On
+
+    ...
+
+    float4 frag(Varyings input) : SV_TARGET
+    {
+        // Return the normal as a value between 0 and 1
+        float3 normalWS = normalize(input.normalWS);
+        return float4(normalWS * 0.5 + 0.5, 1);
+    }}
+```
