Honestly, I’m not entirely sure. I haven’t done it personally, but I know it can be done since we did it on a project I was working on but I have since left the company. After that had gotten working though, UGameFeatureAction_AddChunkOverride was added to the GameFeatures plugin and I believe that’s the critical bit that’s needed. I’m not entirely sure if there’s anything else that has to happen since I haven’t had a chance to do it personally yet.
