Post-processing is that tool that when you finish setting it up and activate it, you’re the first to be amazed.
Let’s see what we have to do to use it. First of all we have to add it to our project so we go to Window>Package Manager and install it in our project.
Once installed, let’s create an empty game object in the scene and add the component “Post Process Volume”.
We will see that there are some parameters in particular Profile, just click on “New” to create a profile and see that our Inspector will update and we can add some effects.
To make visible these effects we must add a component to the Main Camera. Select “Add Component” and add the “Post Process Layer” this component will ask us the transform of the main camera and a reference layer.
let’s create our layer and then go back to the game object that we just created and assign it to itself and the main camera.
We can choose various effects to improve the image quality of the game, for this game I have selected Bloom and Color Grading, but we can have fun trying other effects as well.
On the Color Grading, we will have an alert to manage that is the Color Space, it will ask us to change it from Gamma to Linear to use this effect. To do this just go to project settings and under the player item, we will find the Color Space field.
Unity provides many effects that I want to try as soon as possible, including the Chromatic Aberration that I want to use to simulate an effect related to the speed, I will soon post the results.
