Check how many shader variants your build has in URP

Log how many shader variants Unity compiles and strips.
Read time 1 minuteLast updated 6 days ago
To log how many variants Unity compiles and strips in total in the Universal Render Pipeline (URP), follow these steps:
  1. Open the Graphics settings window.
  2. Open the URP tab.
  3. In the Additional Shader Stripping Settings section, select a Shader Variant Log Level other than Disabled.
  4. From the main menu, select File > Build Profiles.
  5. Enable
    Development Build

    ?

    .
  6. Build your project.
Unity logs the shader variant information to the following locations:
  • The Console window
  • The 
    Editor.log
    log file. Search for the section that begins with 
    Shader Stripping
    . For the location of 
    Editor.log
    , refer to log files.
For each shader, Unity uses the format 
Total=<Number of variants in build>/<Total number of variants>(<Percentage in build>)
. For example, the following log indicates that Unity kept 8 of the 39 variants of the Lit shader, including 1 of the 6 vertex shader variants of the 
ForwardLit
shader pass:
Universal Render Pipeline/Lit - Total=8/39(20.51%)- ForwardLit (ScriptableRenderPipeline) (SubShader: 0) (ShaderType: Vertex) - Total=1/6(16.67%) - Time=0.0691ms...
To export the information in JSON format, follow these steps:
  1. In the Graphics settings window, open the URP tab.
  2. In the Additional Shader Stripping Settings section, enable Export Shader Variants.
  3. Build your project.
  4. In your project folder, open the 
    Temp/graphics-settings-stripping.json
    and 
    Temp/shader-stripping.json
    files.
