In this session, Chris Zuko, Technical Director at Terrible Posture Games, will share all the gritty details behind what it takes to make something like Mix Universe, a node-based musical sandbox in Unreal where all of the audio visuals are real-time (NOT a pre-baked composition). MetaSound, Blueprints, C++, Shaders, and Niagara are all combined together to pull off something that has never been done before in Unreal.


Attendees can expect to learn how Mix Universe uses Unreal's real-time sound analyzers, Quartz Quantization, MetaSounds, and Niagara to make compelling audio visuals along with creating a custom Audio Pool System and Sample Libraries.

Intended Audience

This is for anyone who has ever wanted to explore Unreal's capabilities when it comes to MetaSounds and audio spectrum analysis, setting up an Audio Pool System, making custom sample libraries for midi playback, and driving everything using Niagara for visuals.
