With Unity’s Visual Effect Graph, you can trigger particles to spawn by using events. As an extension of this, you can trigger events using other systems. In this tutorial, you’ll learn what GPU Events are, explore their different blocks, and see an example of their use. Using a fireworks effect as an example, you will also learn how GPU Events can be applied in the systems of a fireworks effect.

Bloom gives the illusion of an extremely bright light and is a great way to enhance add visual ambiance to your Scene.

Vignette is a useful tool to help focus the viewer’s attention on the center of the screen or to add a soft fade to the edges. The term comes from photography, where vignetting refers to darkening or desaturation towards the edges of an image.

Grain can be used to emulate imaging technology, or shape the atmosphere of a scene. In this tutorial, you’ll learn how to apply and adjust Grain as a Post Processing Effect.

Tonemapping is the process of mapping color values from high dynamic range (HDR) to low dynamic range (LDR). In Unity, this means that for most platforms, the arbitrary 16-bit floating-point color values will be mapped to traditional 8-bit values.

Deferred Fog uses information from the Z Buffer to gradually envelop your scene in Fog as it gets farther from the Camera. This can be used for especially thick atmospheres like steamy jungles or underwater temples, or to obscure monsters in a horror game. It's also a classic technique used to hide the Camera's Far plane, and the sudden appearance of geometry, on early 3D-capable computers and consoles, where a long draw distance wasn't feasible.

Lens Distortion can be used for simple effects like creating a fisheye lens for instant replay in skateboarding games or emulating different cinema lenses.

In this tutorial, you’ll create an echo effect using an audio reverb zone. By the end of this tutorial, you'll be able to: Add special audio effects to a scene Describe the science of audio in digital environments. Explain the role of audio in developing atmosphere. Control the priority of different audio sources in a scene by setting Priority settings.

Chromatic Aberration makes your scene appear as though it were recorded through a lens that is unable to converge light at the edges. This is common in low-end lenses, and is a quick and easy effective way to give your scene that “shot on glass” look.

Optimization is a broad topic and how you optimize depends heavily on your specific project. This tutorial should be read as an introduction to optimization tips and suggestions rather than a step-by-step guide that guarantees optimized particle effects for your mobile projects. The process of optimizing particle effects for mobile devices can change depending on the project and can be a complicated task. In this tutorial, we will talk about common pitfalls and optimization considerations that will help you begin the process of optimizing your particle effects for mobile applications.
