After installing Hololight Stream Runtime, you can start your XR experience in Godot. Godot is a powerful open-source game engine, and like any engine, it requires proper integration to work seamlessly with Hololight Stream Runtime. After installing, you can begin streaming XR content from a Godot project—however, this isn’t plug-and-play. Your application must be specifically prepared and mapped to utilize our Hololight Stream Runtime effectively.

The following steps guide you through how to configure and stream Godot’s XR Template to a supported XR device using Hololight Stream Runtime.
