Shader

Shaders are used to define the game's rendering of certain elements.

in Java Edition, two distinct kinds of shaders are used: core shaders and post-processing shaders. Core shaders are used to render fundamental parts of the game such as entities and terrain, while post-processing shaders are used to apply visual effects to the screen after core shaders have ran.

Examples of post-processing shaders include the menu background blur, certain mob vision types as seen in spectator, the Fabulous! graphics setting's fixed handling of translucent object, and the glowing status effect.
