Simple Edge Detection

Simple Edge Detection is a lightweight fullscreen outline solution. The asset includes a single shader and a ready-to-use material. To use it, add a Full Screen Pass Render Feature in URP or HDRP and assign the material. No scripts or additional setup are required.

The shader detects edges using both geometry changes (corners and shape transitions) and color differences in the rendered image, allowing clean technical outlines or fully stylized looks. Outlines can also be distorted with noise for artistic effects.

• Works with orthographic camera

Limitations:
