3D Scanning an Unreal Project?

Hi! My name is Patrycja and I’m a Game Art student. For this semester we’re making AR experiences with the use of ‘8th Wall’. I want to make an experience using the ‘Door Portal’ project on 8th wall and I’d like to showcase my 3D environment I made within Unreal Engine last semester. I don’t have the time to optimize my project for mobile AR and was wondering if there’s a way to 3D scan an Unreal project in engine? If not, does anybody have any ideas on how else I could achieve this? This is my environment for reference: Unreal Engine Sinister Boarding School Environment
Thank you!!
