Rendering graphics in Unity is a complex task. This guide provides a better understanding of the underlying concepts related to rendering, and best practices for reducing the rendering workload on the GPU.

VFX are simulated motion effects added to enhance a scene, ranging from a subtle splash of water to a massive fiery explosion. In this tutorial, you will learn what VFX are, who makes them in the industry, and then you will tinker with a fire effect in Unity. By the end of this tutorial, you'll be able to: Define the acronym VFX. Explain different applications of VFX in real-time 3D experiences, such as gameplay and environmental effects. Describe the impact that VFX can have on the level of polish in a project. Understand the differences between Unity's Particle System and VFX Graph

Some VFX are triggered by a user’s actions, which makes the application feel more responsive and dynamic. In this tutorial, you will create a new smoke burst effect, then allow the user to generate that effect whenever they want to ignite or extinguish the fire. By the end of this tutorial, you'll be able to: Create a single burst of particles, rather than a continuous emission over time by using the Bursts section of the Emission module. Add randomness to a Particle System by using the Random Between Two Constants feature. Change the color of a particle over its lifetime by using the gradient editor and the Color Over Lifetime module. Change the size of a particle over its lifetime by using the curve editor in the Size Over Lifetime module.

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

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.

Post-process volumes allow you to affect all or just a subsection of your Scene. In this tutorial, we’ll look at using both global and local post process volumes, including how to use both in a single Scene.

It’s useful to know the Post-Processing Stack, as it can really deliver amazing effects for your project. It’s applies effects after the main processing pipeline and enhances the overall look of a Scene. In this tutorial, you will learn about the Post-Pocessing Stack.

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.

Unity features a robust Particle System where you can simulate moving liquids, smoke, clouds, flames, magic spells, and a whole slew of other effects. In this tutorial, you'll get a high level overview of the Particle System and its features, so that you can start getting ideas for your own projects.

Screen-based image effects add specialized filters to the application camera which can be used to drastically increase the visual quality of a project. Unity’s Post-Processing Stack replaces previous iterations of screen-based image effects and combines them all together in an easily configurable way. In this tutorial, you will learn to create and configure the post processing stack.
