Building Virtual Avatars for Streaming in Unreal Engine

Turn your iPhone into a motion-capture studio and Unreal Engine into a virtual stage. In this intensive, one-day workshop you’ll import a 3D character, connect real-time facial/body capture from your phone via Live Link, drop the avatar into a scene, and output a live or recorded feed for YouTube, Twitch, TikTok, and more. By sunset you’ll have a ready-to-stream VTuber setup—and the confidence to keep iterating.

• Streamers, VTubers, and content creators seeking high-quality real-time avatars
• Indie game devs & filmmakers prototyping character-based virtual-production workflows
• 3D artists & animators curious about live facial/body capture in UE
• Basic Unreal navigation is helpful; no prior mocap experience required.

• Laptop/desktop capable of running Unreal Engine 5.x
• iPhone (Face ID device; iOS 15+) with Live Link Face or similar app
• Wi-Fi access for Live Link streaming or ethernet connector for iPhone
• Headphones & mic for quiet monitoring and voice capture (optional)
• (Stream software: OBS) pre-installed for final test
