Day 28 — Adding post processing to our project

Hey and welcome.

It’s time we start looking into post processing now that we’re starting to round out our game. Post processing let’s us add filters and effects to our game on top of what’s already in place, kind of like PhotoShop in a way.

To get started with it you’ll need to install it first from Window > Package Manager after switching it to look for packages in the whole Unity Registry rather than locally.

Right there’s a few things for us to do first before we can get our post processing working. First we’ll need to create ourselves an empty object called PostProcessing to handle our processing magic. Next we add the Post-process-volume component which is what we’re going to use to alter things. You’ll find though that changing the settings won’t do anything to our game so there’s one last thing we need to do first.

Let’s go ahead and create a new layer first by using the dropdown in the top right of the inspector.

Call it something along the lines of Post Processing and then head on over to your main camera and add in a new component, this time it’s the Post-process-layer. With that added, set the layer to your new post processing one you created and you’re now set to go about altering the graphics in your game.

Back in your post processing object click the add effect option and choose the bloom option. Check as many of the boxes you like and honestly just have a play about with things, here’s me changing the intensity to show how drastically we can affect things with post processing.

It would be better to just have a play about with different effects and settings until you come across something that you like, here’s another gif of me messing about with colour grading.

Go wild and have fun! The designers among you will no doubt get a good amount of enjoyment from this.
