How to use Post Processing in Unity
Having beautiful sprites is nice, but there’s something more we can do to enhance the visual appeal of our game. We can add a Post-process volume to our scene and use that to enable a number of options — including ludicrously excessive amounts of bloom.
To get started, create a new empty object in your scene Hierarchy and call it “Post Process Volume.” Add the Post-process Volume component to the object.
Above the Transform component, there’s a Layer dropdown. I need to add a new layer called “Post Processing” in order for everything to work correctly. Also, hit the “New” button next to Profile in the Post-process Volume component.
Now, before I add any effects, I’ll select my main camera and add the Post-process Layer component to it. Add the Post Processing layer into this component with the Layer dropdown.
Now, back on your Post Process Volume object, I can click add effect and choose from the dropdown.
That’s basically it. Each effect has its own sliders and values to play with. I suggest fiddling with all these settings to find the look that appeals most to you.
Next time I’ll be adding another layer of immersion with sound effects.
