For a long time now, the Lumber Tycoon 2 tree generation system has been fascinating me, and I’ve been trying to recreate my own system but I kept failing until now!
The script probably has a ton of bugs and is obviously not the best. I struggle to use CFrame, so it’s pretty hard for me to fix them, but I thought that it would be cool to share this resource since there isn’t much about open source tree generation system out there.
