A wireframe and outline (2-in-1) effect for Unity that uses depth-based edge detection to render thick, quality post-processing wireframes and outlines. You can control the line thickness, edge detection threshold, colour, and blend state. Unlike the typical edge-detection techniques of using a sobel filter/kernel, we compare depth against the local area average- calculated using what is essentially box blur.

• Built-in pipeline.
• Tested with Unity 2021.3 (LTS).

Easy as,

1. Attach these two components to your camera.
2. Set to render at least 'Depth', and assign the material.

...That's it.

You can then tweak the material, for example: to get this automatic per-object line colour look.

Or to render thick, painterly strokes- best used in combination with some kind of stylized surface shader.
