Objective: Adding post processing to your game.

Package Manager is where you install a variety of Unity owned and maintained products.

Open windows at the top of unity and select package manager. After the list has loaded, select post processing and install. The post processing folder will be nested inside the package folder on the asset view.

Now you need to create a post processing profile. Create an empty object and rename Post Processing Volume.

This game object will control all effects for your video game.

Add component, Post processing Volume.

This will allow you to add a profile and being adding image effects.

Check the “is Global” box so the entire environment, camera, everything being viewed will be affected.

Select New next to the profile. This will create a profile under the scene folder in the asset view.

Select the post process in the hierarchy. On the inspector view select add effect, Unity, then bloom.

You won’t be able to see the effects take place. To have those effects take place you need to enable the main camera to render the effects.

Select main camera and add component Post Process Layer.

To create a layer, select post process from the hierarchy and at the top of the inspector select the layer drop box and add a layer named Post Process.

Got back to the main camera and add the post process layer to the post process layer component under layer.

Now the bloom will affect the look of your game. You now know how to add post processing to your game. With this you can change the look and feel of the game and take your game to the next level.
