Which Unreal version are you using? I'm currently working on my own project and making all the programming and the arts by myself, and I'd like to give an honest suggestion to avoid Unreal 5 as much as possible and keep using UE4.27, it's the hard lesson I learned myself and I'd expect few years for UE5 to be usable for any serious project given how laggy and buggy the current version is, if you know some famous projects like Operation Lovecraft:Fallen Doll they were also stuck by performance issues with Unreal 5. I'm in the progress of downgrading my project from UE5 to UE4.27, and using UE5 Lumen and Nanite just for videos and cut scenes, UE5 without Lumen is actually worse than UE4 for the image quality and the game performance
