Do you have photogrammetry turned on? That looks like autogen buildings.
Well I thought I did. I double checked and photogrammetry is turned on, but my rolling cache is set to 0. Maybe that’s the problem? I’ve moved my rolling cache location to an external hard drive with more space, and have upped the limit to 100 GB. I’ll restart the computer after it’s done building the location. Maybe that will help? I hope so. This Leggo Land skyline is not what I expected.
