Everyone loves Instagram filters, right? Well why not have them on your video game?

Post-processing is the art of adding visual effects to your game to really add some atmosphere and identity to what you’re building.

In the above pictures, you can see a subtle change on account of the post-processing effects that I’ve already. I won’t waste your time explaining what each one does, but instead help you walk through adding your own post-processing volume so that you can play around with them yourself!

  1. Go into your Package Manager and install the Post Processing package from the Unity Registry.
  2. In your Hierarchy, right-click, 3D Object > Post-process Volume
  3. Open this new object in the Inspector and add a new layer called “Post Processing”. Don’t forget to set it as this Object’s layer once you’re done.
  4. Check off “Is Global”, and then create a new Profile by clicking “New” next to the Profile property.

5. Now head over to your Main Camera object and add a new Post-process Layer component to it. Set the Layer to your newly made “Post Processing” layer.

6. Back on your Post-process Volume Game Object, you can now add, and see, a number of different visual effects. Play around with different combinations and custom values to find an effect that works for your game.

That’s it! Have fun with your post-processing explorations. Be careful, there is such a thing as “too much”.
