In this video, we are going to take a quick look at the 2D Pixel Perfect feature introduced with Unity 2018.2. Pixel Perfect allows you to utilize the Pixel Perfect Camera component to achieve sharper pixels for your 2D pixelated games!
Try the Pixel Perfect Preview package to stay true to your pixel art vision. The Pixel Perfect Camera component will help you get perfect, crisp pixels – regardless of the screen size – by making all the calculations automatically for you.
Your sprites will even benefit from the feature when they are in motion or rotating, always keeping a sharp pixelation, without having to add interpolation to smoothen the edges as illustrated below.
