There’s a button for adding an override, which means you can add to the list of post-processing effects that you control and not leave it up to the app. Select the Post-process Volume in the Hierarchy, and look at the Inspector. In this project’s case, the volume has already been set to Global, meaning it will affect the entire scene regardless of your current location. A post-processing volume is an object that determines the area in which post-processing effects are applied. Give the project a name and set a location for it, then create the project.įigure 2: Using the Universal Render Pipeline templateĪs mentioned before, this project template comes with a post-processing volume already created for you. The Universal Render Pipeline template will be used this time because it already has a scene created and everything needed for implementing post-processing effects. Start by creating a new project within the Unity Hub. Now that you’re familiar with some post-processing effects, it’s time to create a project that puts them to use. Changing any of these will tint the image color based on the values given. This can also be handy for creating a scene from the perspective of a fish.Ĭolor Adjustment: This effect will be separated into three sliders that represent the red, green, and blue values. Depending on the values given, you can achieve a wider field of view. Lens Distortion: This effect simulates real-world distortion caused by an actual camera lens. You can adjust the thickness and intensity of the grains to get the exact look you’re going for. The intensity of this effect changes how much of the edges darken.įilm Grain: Almost exactly as the name of the effect implies, this places an old-school-styled film grain over the image. Vignette: The vignette property creates a dark edge that goes all around the screen. This may remind you of wearing the 3D glasses with the red and blue lenses. This is most clearly visible with light sources and is a popular effect for making an environment appear brighter and more lively.Ĭhromatic Aberration: Chromatic aberration disperses colors along the dark and light areas of an image. Here is a list of all the post-processing effects being used in this project and what they do.īloom: The bloom effect is what gives bright objects a soft glow, making your brighter areas stand out as a result. While the project will focus on only a single property per effect, many post-processing effects have multiple properties that can all be changed in code. Post-processing effectsīefore diving too deep into the project, it’s helpful to understand the various effects. By the end, you will be able to use the UI to adjust the properties of several post-processing effects, seeing the changes in real-time as you do so. Then, the project will be created with a UI set up before getting into the code that will make the project function. Before that, a brief description will be given of the post-processing effects used to explain what is being demonstrated. To help you learn how to use this, a project will be created that lets the user change the app’s post-processing properties by manipulating various user interface (UI) elements. In this article, I’ll show you how to use post-processing effects in Unity. This allows the developer to achieve effects such as applying a vignette under certain conditions or changing the type of film grain used. While an app can certainly have its post-processing effects set in advance, there’s also the option to change them during runtime using C# code. In the video game space, this is rarely the case. Typically, when people think of post-processing, they think of it as a static item or something that cannot be changed once applied. This usually includes effects like giving lights a soft glow or tinting the image a certain color. You may have heard the term “post-processing” before, but what does that mean? In the context of images and video, it is the application of various visual effects to improve the visual elements of an image.
