Thanks, I’ll give that a try. There’s a lot to learn, and TIN was one of those things I just ignored. I did notice that those things went away when I turned off Photogrammetry, but that certainly wasn’t a useful solution.
Just tried it, and it works great! Also looked up TIN, so that makes it more clear. Now I can get rid of all the generated trees and just put it the type and size I want.
Maybe Blender is next?
