Which of these options can post-processing NOT accomplish?

Post-processing in game development refers to the techniques used to enhance the visual quality of rendered images after the initial rendering process but before displaying them on the screen. The process can include various effects such as bloom, depth of field, color grading, and anti-aliasing, which all contribute to improving the aesthetic of the game visuals.

The option that states post-processing can "completely transform the game's engine" stands out because post-processing is fundamentally about modifying the visual output rather than altering the core functionalities or architecture of the game engine itself. An engine is responsible for the underlying mechanics of rendering, physics, input handling, and more. While post-processing can improve how the visuals are presented to the player, it operates on the output from the engine rather than modifying the engine’s capabilities or base structure.

The other options indicate functionalities that are well within the scope of what post-processing can achieve. For instance, altering an image's color balance is a common post-processing effect that can greatly affect the mood and tone of a game. Similarly, adding a visual style allows developers to establish a unique artistic approach, which is often achieved through post-processing filters. Finally, enhancing overall image quality is a primary goal of many post-processing effects, as these techniques are designed
