Clean Outline 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.

Only supports built-in render piple by now,.

Requires Unity's Post-Process package.

Supports PC/Mobile, both forward and deferred(only on PC) rendering could work.

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.
