For a while, the game has not been running as well as I wanted it to, so I took an opportunity to fix things after watching a talk from UnrealFest 2022. I updated a few assets as well. I used an auto-landscape material which does not give me exactly the results I wanted, but it runs faster and looks ok. I didn't fix it to my liking because the lighting would not build, so I have dry brown grass instead of green grass for my landscapes. That is easily fixed by raising the landscape, but it alters my cinematics. Suitable lessons all around for this; please enjoy.
