The 2D Space shooting in its infancy is a playable prototype at the very least. There can be so much more, I want to take this project step by step through the basics first. The purpose of post-processing is to improve the appearance of the game.

  • First, go to Window/Package Manager/Post Processing
  • Locate and install Post Processing package
  • Create Empty Object name it Post Process Volume
  • Add Component Post Process Volume to the new objects inspector
  • Left Click the New button next to Profile on the Post Process Volume script in the inspector. It automatically adds.
Go to Window/Package Manager/Post Processing, locate and install the Post Processing package
Left Click the New button next to Profile on the Post Process Volume script in the inspector. It automatically adds.

Now in the scenes folder, there will be a GameScene_Profile/Post Process Volume Profile. Then I can start adding effects.

  • Left-Click Add effect/Unity/select the desired effect
  • For starters, this project can get some Bloom effect
  • Select Main Camera Add Component Post Process Layer
  • Create a new Layer called Post Process
  • Select the Post Process Volume/Click the drop-down box by layer in the inspector/Add Layer, name it Post Process
  • Select Main Camera and set the/Post Process Layer Componen/Layer . Not the main layer keep that set to default
  • Select the Post Process Volume and set that Layer to Post Process as well
Left-Click/Add Bloom, Mian Camera Add Component Post Process Layer
Post Process Volume/Layer/Add Layer/Name layer Post Process, set Post Process Volume Layer and Main Camera/Post Process layer Component layers to Post Process

From there I can modify the settings on the Post Processing/Bloom. Mess around and find what you may want or need for your project.

  • Adjust Bloom
  • Add Component Color Grading, turn it On, and check the Mode box
  • File/Build Setting/Player Settings, fin color Space and change it to Linear
  • Exit out of Project Settings
  • Set the Mode to HDR (High Definition Range)
  • Find a ToneMapping Setting you like (Going with ACES)
  • Adjust Temperature and Tint if you want or need to
Setting the bloom level, I went with 10 intensity
Add Component Color Grading, turn it On, and check the Mode box
File/Build Setting/Player Settings, fin color Space and change it to Linear
Exit out of Project Settings, Set the Mode to HDR (High Definition Range)

It is good to spend some time becoming familiar with the effects. Experiment with them to gain experience plus get a result that is good for the project. There are other effects and even more settings on the ones I am using here.

  • I ended up going with 45 Bloom Intensity after all.
  • Activated Color on Bloom Set to R-167/G-219/B-255
  • Color Grade Temp to -20 Color Filter to R-255/G-196/B-196
Without Bloom and Color Grading
With Bloom and Color Grading on

I went on ahead and did another set of settings here are the results Below.

  • Bloom 40
  • Threshold 0.8
  • Bloom Color R-255/G-230/B-100
  • On Color Grading Changed Color Filter to R-172/G-212/B-255
