About this resource

A prototyping-friendly outline for URP: add the renderer feature, add the Custom / Outline Volume override, and put an object on one of four named rendering layers to outline it. Each layer has its own colour and parameters; the border width is shared for performance reasons.

Limitations listed by the author: no per-object outline widths, no alpha clip, and no vertex-animated outlines. A static ForceCullPass flag lets you skip the passes entirely when nothing is outlined.
