This allows us to create profiles for post processing! By clicking New next to profile, we will create a new profile that will automatically be added to our scenes and will allow us to add effects. First, we create a post processing layer, add our post processor to that layer, add a “Post Process Layer” component to our main camera, change the layer in that component to the post processing layer, then add effects in our processor! This allows us to add effects such as bloom to our game:
