Day 28: How to use Post Processing in Unity

Objective: Setup the ability to use Post Processing.

To use Post Processing, we need to install it from the package manager. To open Package Manager is go to Windows -> Package Manager.

In the Package Manager, top left of the window, hit the drop down and make sure Unity Registry is selected. When Unity Registry is selected, you can either scroll down the list and find Post Processing or you can search for it in the top right corner.

Once you have it selected in the bottom right corner you can select Install. Wait until it’s finished downloading.

Now that it’s installed its time to set it up for the effects to work. We will need a Empty Game object created. We’ll name it PostProcessingVolume. On the empty game object add the post processing volume component.

We need to check IsGlobal and click new on the profile.

Next will be to add the post processing layer to the camera. This is how the effects will affect the scene.

You’ll notice that a Layer needs to be selected. We will go to the top of the inspector and select layer and add layer. Once you create a layer called PostProcessing, go to the volume and add the layer on the object. Go back to the camera and select the post processing layer in the layer component.

We are now able to use post processing and have it affect our game. In the next article we will go over some of the effects to make the game look better!
