Edge Detect image effect adds black edges to the image wherever color differences exceed some threshold.
If more sophisticated geometry-based edge detection is required, the Standard Assets also provide such a normals and depth-based edge detection effect.
As with the other image effects, you must have the Standard Assets Effects package installed before it becomes available.
Property: | Function: |

Threshold | Edges will be displayed wherever the color difference between neighboring pixels exceeds this value. Increasing the value will make edges less sensitive to texture or lighting changes. |
This effect should run on all hardware that Unity supports.
