RNBO MetaSounds
December 10, 2025 · View on GitHub
This is experimental software—use at your own risk, and know that anything in this repository could change in the future.
UE and RNBO version
This repository will help you create custom nodes for a MetaSounds graph in Unreal Engine 5.7+ using the C++ source export in RNBO 1.4.2+.
In addition to nodes which will hold your RNBO exports, this repository will also build utility nodes, for example, a Transport node which will help you utilize RNBO's built-in transport within your MetaSounds graph.
Example Project
To check out an example of an Unreal Engine project full of RNBO exports, download this project and open up its README.md.
