🎭 Mask Materials:
Outline3DSimple-Msk-ColorTextureMask-Default.shadergraph
Outline3DSimple-Msk-ColorTextureMaskDepthTested-Default.shadergraph

🖼️ Final Composite Material:
Outline3DSimple-Cmp-Silhouette-Outside-Default.shadergraph
(Or any other Simple tier Composite shader)

The Simple Renderer Feature supports all Simple Composite outline shaders that only require any of the following three mask textures:

⬜Texture2D_OutlineColorTextureMask
Binary white on black color texture mask of the Outline3D objects
🧱Texture2D_OutlineColorTextureMaskDepthTested
Binary white on black color texture mask of the Outline3D objects, depth tested against other non-outline scene geometry using L Equal depth comparison. (For the example image above the Outline3D components of the bunny in the front and the turret in the center were disabled)
📸Texture2D_CameraOpaqueTexture
A copy of the URP camera color buffer for performing edge detection on the scene's color and for other full-screen effects.

The default Render Pass execution order of the 🧑‍🎨Outline3DRenderFeatureSimple is shown in the diagram below. After the mask Render Passes are done, the Outline3DRenderFeature executes the final full-screen composite pass which renders the final outlines to the scene cameras:
