Any reader will need to have installed a version of Unreal Engine on their computers; the latest version, if possible. Most of the recipes we'll look at should work on different engine versions, but we recommend 4.22 in order to have the latest features installed.
Prior knowledge about the engine is not a must, but having some working experience with Unreal will help the reader enjoy a smoother experience throughout the book. Whilst no coding skills are required, some fluency with the Blueprint visual scripting language would also be of great help.
