I can’t get rid of the photogrammetry vegetation either. I created the polygon, assigned to exclude all on it, and added “Vegetation” checkbox. Scene is working as I have all my custom made buildings loading in just fine, but the photogrammetry trees do not go away.
They are removed in the project, but after exporting and just flying the game, the photogrammetry data is still there.
Any ideas what I am doing wrong?
