How it works: As named, it uses Sobel operators for edge detection. One of these is the Sobel post-process, which yields interesting, but inverted (negative), results. ASE provides a wide range of examples of custom shaders for learning and reusing. Instead, let’s create these effects as a post-process, using one of the shaders from ASE’s library.

Obviously, we could use outline shaders for objects, but those come with some limitations. If, for example, we are in need of a linear, black & white render that looks similar to a CAD drawing

Basically, it’s similar to Unity’s shader graph, but is not limited to SRP (both lightweight and HD rendering pipeline) and it works great in both the standard and built-in rendering engines. Amplify Shader Editor (ASE) is a powerful visual shader editor for Unity and is available in the Asset Store. In this case, we can use an awesome tool – Amplify Shader Editor from Amplify Creations. There are a lot of articles on how it installs and functions, including the official documentation.īut what if the generic effects library provided with Unity is not enough? The package manager gives us access to a collection of filters and effects, such as color grading, anti-aliasing, screen-space ambient occlusion and many more. In this article, we will focus on the most popular, being the built-in rendering pipeline. All of these pipelines possess their own post-processing components. Limiting our scope to the Unity environment, we have access to 3 different rendering pipelines, these include the “built-in”, “lightweight” and “high definition” rendering pipelines. Some effects will require additional passes or data from other buffers, but these are basically “material” for the rendered image. More precisely, we can say that it is working on a rendered buffer before an image is displayed on the screen. Post-processing is a method of adding effects to rendered images.
