Screen‐Space Outline

Modes

Screen-Space Outline can work in two modes:

• Default: as a post-processing pass;
• After Opaque: when it is drawn on top of the camera render target after rendering opaque geometries. This mode uses hardware blending, thus it draws directly to the render target.

📝 Note: Screen-Space Outlines do not apply any blur or anti-aliasing on their own. An anti-aliasing effect like FXAA can help smoothing them out.

Setup

Default

• In the project window, right click and select Create/Toon RP/Post-Processing/Screen-Space Outline.
• Go to your pipeline asset, make sure the post-processing is enabled, and add the newly created asset to the Post-Processing Passes list.

After Opaque

• In the project window, right click and select Create/Toon RP/Extensions/Screen-Space Outline (After Opaque).
• Go to your pipeline asset and add the newly created asset to the Extensions list.

Effect

The outlines are applied using an edge detection algorithm. Edges can be detected based on scene color, depth, and normals. Multiple filters can be enabled at the same time.

Color

📝 Note: After Opaque mode does not support the Color Filter.

Depth

📝 Note: Depth Filter requires Depth Pre-Pass.

Normals

📝 Note: Normals Filter requires Depth Normals Pre-Pass.

All Filters Combined
