Introduction

In this tutorial, I will showcase the new ray-tracing features made available to all users in Unreal Engine version 4.22.2. To compare the changes introduced by ray-tracing I have built from scratch a unique environment that includes a variety of materials and modular assets.

I am always excited to share my discoveries on new software and techniques, and I feel like ray-tracing is a great tool that can give you greater control over the visual aspect of your scenes.

I will personally continue experimenting with these features and I hope to see them integrated into more games and projects in the coming years, as well as wish for continuous support from hardware manufacturers to the development of amazing technologies like these.

Step 1: Basic Requirements and Setup

To enable ray-tracing in your project you will need to install Unreal Engine version 4.22.2 (or newer), Windows Build 1809 (or the most recent update) and an Nvidia graphics card (either RTX or 10 series) with the latest drivers installed. Not all the 10 series cards are currently supported, check Nvidia’s official website to see if yours is compatible.Step 1: Basic Requirements and Setup

Inside the Engine, in the Project settings force DirectX mode, enable ray-tracing and enable skin cache if you haven’t already, then restart the engine.
