A thick line of trees are a great pollution-consumer, but it takes a lot of time to place (just holding the mouse button, going back and forth, for 15 minutes... no fun). It would be great if they were blueprintable.
As a workaround, maybe the blueprint strings mod could be used. I could modify a string by hand, encode it, and load it in the game. I guess this would work?
But it would be even cooler if it was just supported without additional mods. I briefly looked into it, but it seems the "tree" type (saplings are trees) is just not blueprintable. This is not documented anywhere, but that's my best guess. Removing the flags (e.g. not-repairable, breaths-air) does not change anything.
