How to use Post Processing in Unity
Day 23 — Aspiring Game Creator
2D Game Dev: Galaxy Shooter
Looking at stills, the effects seem negatable, but having a small bloom for a burst of light, ACES tone mapping to reduce the bloom with richer blacks and a touch of blue and purple to cool down the scene definitely feels different.
Objective: Install Unity’s Post Processing Effects
Depending on the version of Unity and the type of project — 2D, 3D, URP — installing Post Processing is usually the first step.
Since Galaxy Shooter started as a basic 2D project, the first step is installing Post Processing via the Package Manager.
- Create an empty game object named: Post Process Volume
- Add Component: Post Process Volume
- Set the component to: Is Global
- Create a NEW profile (profile is added under SCENES folder named after project_Profiles).
- Create a new Layer: “Post Processing”
- From the Main Camera => add component: Post-processing Layer
- In the Post-processing Layer component, change the Layer to the new Post Processing layer created earlier.
- Back to the Post Process Volume object, change layer to Post Processing (below):
- Main Camera => Post Processing Layer: change the default “Nothing” layer to the add the new Post Processing layer (below):
Finally, returning to the Post Process Volume, effects can now be added.
The first effect to make the most notable change is Bloom.
Add Bloom, choose ALL and crank Intensity to 20+.
