A fullscreen post processing effect that adds subtle outline effect to the scene, using fast edge detection algorithm. Fully works with URP Render Graph in Unity 6.
 
What is it?
Contour is a post processing effect that draws subtle edge/outline around objects in the scene. The edge detection algorithm selectively reads from scene color, depth and normal vectors.
