- **Rendering Pass** Specifies the rendering pass that HDRP processes this material in.
• **Before Refraction**: Draws the GameObject before the refraction pass. This means that HDRP includes this Material when it processes refraction. To expose this option, select **Transparent** from the **Surface Type** drop-down.
• **Default**: Draws the GameObject in the default opaque or transparent rendering pass pass, depending on the **Surface Type**.
• **Low Resolution**: Draws the GameObject in half resolution after the **Default** pass.
• **After post-process**: For [Unlit Materials](../../../Unlit-Shader.md) only. Draws the GameObject after all post-processing effects.
