So what is it?

This is the official Post-processing Stack repository from Unity Technologies, the company behind the Unity game engine. Post-processing refers to visual effects applied to a rendered image after the main scene has been drawn, such as bloom, color grading, depth of field, motion blur, and similar effects that make a game or interactive scene look more polished. The repository hosts two versions. Version 1.x is deprecated and no longer maintained. Version 2.x is the current active version and is what most Unity developers would use. Each version lives on its own branch within the same repository. The README itself is extremely brief and only points to the two branches. There is no documentation in the README about how to install the package, what effects are included, or how to configure them. Users looking for setup guidance would need to explore the individual version branches or consult the Unity documentation separately. This package is relevant to Unity developers who want to add screen-space visual effects to their projects. It is an official Unity Technologies release rather than a community mod.

Prompt 2

How do I configure depth of field in Unity post-processing v2 so that objects close to the camera are sharp while the background is blurred?
