About this asset
With Linework you can easily render outlines and fill effects.
5+ years in the making, Linework is the culmination of years of experimentation that I have done with outline rendering in Unity. Made with love ❤️.
Documentation | Discord | Bluesky
✅ Multiple techniques.
There is no one-size-fits-all solution for outlines. Linework includes multiple techniques, balancing visual fidelity and performance.
✅ Performant.
Leveraging the power of the SRP batcher and the Unity 6 Render Graph, Linework is able to render multiple outlines within a single batch.
✅ Easy to use.
A considerable amount of development time has gone into finetuning the user experience for Linework so that it is as user-friendly as possible while still being flexible.
Features

- Advanced edge detection features such as a section map and world-space distortion/breakup for hand-drawn effectgs
- Surface Fill effect for rendering screen-space fill effects and patterns
- Use rendering layers to easily configure per-object outlines and stack effects
- Custom editor UI and settings for easy authoring of outlines
- Full source code included
- Extensive documentation
- Great support
- Compatible with alpha cutout shaders
- Compatible with vertex animation

Technical details
Linework contains 5 effects to render outlines and fills. These can be added as renderer features to your URP renderer.
Fast Outline: Renders outlines by rendering an extruded version of an object behind the original object.
Soft Outline: Renders outlines by generating a silhouette of an object and applying a dilation/blur effect, resulting in smooth, soft-edged contours around objects.
Wide Outline: Renders an outline by generating a signed distance field (SDF) for each object and then sampling it. This creates consistent outlines that smoothly follows the shape of an object.
Edge Detection: Renders outlines by detecting edges and discontinuities within the scene, such as differences in *depth*, *normal vector*, *color*, or *custom input buffers*. This process creates a consistent outline effect that is applied uniformly across the entire scene, making it suitable for both external and internal object boundaries.
Surface Fill: Renders fills by rendering an object with a fill material.
Each effect has an extensive range of settings such as
- which objects the outline is applied to (using the rendering layer system)
- the visuals of the outline (thickness, color etc.)
- the behavior of the outline (where it should appear)
