How to set up Post Processing Package in Unity 2021 and bring game to AAA status
Post Processing effects bring great adjustments to color, focus and many more effects that can be layered on the camera’s field of view. To start, download and install the package by going into the Package Manager window and installing the Post Processing package. Once that is set up, create an empty game object, reset its transform and add the Post-process Volume component to it, call this game object the same way. Add a layer inside this object called Post Processing. Set the Is Global checkbox to true and add two effects; let’s start with Bloom and Color Grading.
To notice this effects, go to the main camera, add the Post-process layer component and set it’s layer to the recently created layer for the Post Processing.
Once this is set up, the effects will be tweaked to bring that game to a AAA status and enhance the artwork to it’s desired visual state.
Since the Directional Light is somewhat low on brightness and intensity, we can bring more bloom with the following effect and configuration:
Main tweaks here are on Intensity set to 10, Threshhold to 0.7 and changin to color to a similar one with the background’s brightness effects.
Now on to the Color Grading:
The mode is set to High Definition Range (make sure in the build settings > player settings > other settings that the color space is set to Linear), the Tonemapping is set to ACES, temperature is tweaked to look colder with a -7 effect and the Post-Exposure(EV) is set to 2 to give the objects a more brighter and detailed look.
Even thought the post-processing effects are small, there is a more vivid and brighter look at the player, enemies and even the asteroid. The life indicators UI also looks much neater, and the background image as well as the explosions have a brighter bloom included. These effects can be programmed and altered with code to a much greater extent to give even more feedback to the player, like a red screen overlay every time the player is hit, or maybe when the player has one life left.
