To get the most out of this book

Before diving into Unreal Engine’s Niagara, it’s recommended that you have a basic understanding of the Unreal Engine editor. Additionally, familiarity with visual scripting languages such as Blueprint or similar programming languages will be helpful but is not required.

It’s also beneficial to have a general understanding of computer graphics and the concepts behind particle systems, such as emitters, particle lifetimes, and particle attributes. Familiarity with vector math and basic physics concepts can also be useful when working with particle simulations. Some of these basics are covered in the initial chapters.

All the exercises in the book are available in a project posted on the GitHub link given in the next section. If your Niagara systems are not working as intended, please download the project file to find examples of working Niagara systems and figure out what you may have overlooked. If you are using a more recent version of Unreal than 5.1.1, please double-check for any errors that may crop up in the project during the project upgrade.
