Clean Outline URP samples Depth and Normal data in post processing shader to create outlines.

Providing quite some parameters to tune the final outline result.

Friendly for low-poly games if you want a global outline effect instead of setting up outlines in materials for each object.

Support Unity 2023's new APIs.

Requires Unity 2020.x+ in URP

Supports PC/Mobile

Package contains simple example scene with very basic models. The fancy scenes in the preview pictures are just demonstration of the outline and not included in the examples.

Limitations :

- Cannot work with colors in sprites/images, as post processing requires Depth and Normal informations of 3D objects in scene.

- Transparent object can't have outlines, as in most cases their write depth is off by default.

- Post processing will affect all the colors on screen, if you want more detailed outlines for different objects, you might need to use outline shader for each object by excluding object normals.
