I built a Spout integration for Unreal Engine because I needed a way to share real-time render output from UE with external applications. Most of the existing Unreal options I found were either unmaintained or part of commercial toolsets that didn’t fit my use case, so I decided to put together my own solution.
The plugin is open source and free. It’s based on an older, unmaintained repository that I reworked for my needs. It currently works on Unreal Engine 5.5 and newer. Earlier versions have some unresolved compilation issues.
It’s not bug-free, but it’s usable for many real-time use cases with proper testing. If you need a fully production-ready commercial solution, there are dedicated products available that may be more suitable.
