Scene Graph is now available as an Experimental feature in UEFN
We release tools as Experimental to give you the chance to try out new functionality that is still under development. This allows you to try out new features and helps us improve them based on your feedback.
Please note that you won’t be able to publish content created using it until the Early Access release. The timing of the release is still to be determined, and we’ll share more details in the future.
Scene graphs are particularly useful when working on environments populated with large amounts of content. If you’re looking for a way to build richer, deeper Fortnite islands in the future, this feature is for you.
