UE5 Arch Viz - "A Room"

As I work more in Arch Viz, I've been on a mission to figure out the best practices, for using UE5's Lumen, for Arch Viz. I created this scene in about a week, with the purpose of testing multiple lighting scenarios, and troubleshooting lumen issues, when working in a arch viz scenario, which demands high lighting fidelity. All lighting is done through UE5's Lumen, except for the shadows and translucency, which are set to raytraced. I purchased the couch asset from CGTrader, and then went to town, modeling and texturing all the architectural, and interior design assets, in Blender. The tree is custom made by me, using Speedtree 9. I discovered quite a bit of quirks of Lumen and fixes for said quirks, in my creation of this scene, and will be taking these lessons learned, into my next project, which should be uploaded soon.
