WebbPost-processing effects enable artists and designers to define the overall look and feel of the scene through a combined selection of properties and features that affect coloring, tonemapping, lighting, and more. A special type of volume, called a Post Process Volume, can be added to a Level to access these features. WebbAs we can see on the picture above, only quadrilaterals were highlighted with a border. Other shapes, like circles, triangles, stars, etc., were filtered out, which means that although quadrilateral finder gave us some points as 4 corners, the further check for fitting assumed quadrilateral did not pass. Which is nice. Detection of triangles
