Unreal Engine 4 Virtual Reality Projects

Overview of this book

Unreal Engine 4 (UE4) is a powerful tool for developing VR games and applications. With its visual scripting language, Blueprint, and built-in support for all major VR headsets, it's a perfect tool for designers, artists, and engineers to realize their visions in VR. This book will guide you step-by-step through a series of projects that teach essential concepts and techniques for VR development in UE4. You will begin by learning how to think about (and design for) VR and then proceed to set up a development environment. A series of practical projects follows, taking you through essential VR concepts. Through these exercises, you'll learn how to set up UE4 projects that run effectively in VR, how to build player locomotion schemes, and how to use hand controllers to interact with the world. You'll then move on to create user interfaces in 3D space, use the editor's VR mode to build environments directly in VR, and profile/optimize worlds you've built. Finally, you'll explore more advanced topics, such as displaying stereo media in VR, networking in Unreal, and using plugins to extend the engine. Throughout, this book focuses on creating a deeper understanding of why the relevant tools and techniques work as they do, so you can use the techniques and concepts learned here as a springboard for further learning and exploration in VR.

Going further


There are a few ways we could further improve on what we've done here:

  • First, detecting grabbable objects by distance gives us fuzzy results. It doesn't take the object's size into account. Using a sphere to represent our grabbing hand and testing for overlaps against this sphere is going to give us more accurate results. If you'd like to refactor this code to use that method, the VR Template project contains a good example.
  • Second, our haptic feedback effect feels indistinct. It fades in and out evenly, and doesn't provide much of a physical sensation. Editing those curves to provide a sharper attack could make the effect more convincing.
