ShaderLab command: ZWrite

Sets whether the depth buffer contents are updated during rendering. Normally, ZWrite is enabled for opaque objects and disabled for semi-transparent ones.

Disabling ZWrite can lead to incorrect depth ordering. In this case, you need to sort geometry on the CPU.

使用法

This command makes a change to the render state. Use it in a Pass block to set the render state for that Pass, or use it in a SubShader block to set the render state for all Passes in that SubShader.

Signature Example syntax 機能
ZWrite [state] ZWrite Off Enables or disables writing to the depth buffer.

Valid parameter values

パラメーター   機能
ステータス On Enables writing to the depth buffer.
Off Disables writing to the depth buffer.

This example code demonstrates the syntax for using this command in a Pass block.

Shader "Examples/CommandExample"
{
    SubShader
    {
         // The rest of the code that defines the SubShader goes here.

        Pass
        {    
              // Disables writing to the depth buffer for this Pass
              ZWrite Off
            
              // The rest of the code that defines the Pass goes here.
        }
    }
}

This example code demonstrates the syntax for using this command in a SubShader block.

Shader "Examples/CommandExample"
{
    SubShader
    {
         // Disables writing to the depth buffer for this SubShader
         ZWrite Off

         // The rest of the code that defines the SubShader goes here.        

        Pass
        {    
              // The rest of the code that defines the Pass goes here.
        }
    }
