Depth Mask Pass

📖 Description

Captures the depth values of Outline3D objects into a depth texture. Used for contour outlines and depth-based edge detection in Composite Shaders.

🔧 How It Works

  • Inputs: Outline3D objects.
  • Process: Draws objects to a depth-only render target with raw depth values.
  • Outputs: Texture2D_OutlineDepthTextureMask (D32_SFloat_S8_UInt).
  • Code Example: 
    // From OutlineDepthMaskPass.RecordRenderGraph
TextureDesc depthDesc = resourceData.cameraDepthTexture.GetDescriptor(renderGraph);
depthDesc.format = GraphicsFormat.D32_SFloat_S8_UInt;
TextureHandle depthMask = renderGraph.CreateTexture(depthDesc);
builder.SetRenderAttachmentDepth(depthMask, AccessFlags.Write);

📋 Requirements

  • Materials: outlineDepthMaskMaterial.
  • URP Settings: Depth buffer enabled.
  • Dependencies: None specific.

🏷️ Tier Usage

  • Available in: Basic, Advanced, Pro.
  • Conditional: Runs if Composite Shader has _OutlineDepthTextureMask.

🐛 Troubleshooting

  • Issue: Incorrect depth.
    • Fix: Ensure ZWrite On in material.
  • Performance: Low cost.
