here are some pinetrees for the terrain menu.
The plugin includes some single and grouped pine trees. You can select them individually or use the randomizer (the symbol with dices).
I've set "auto build" to false, so the trees won't be built automatically when creating a new map. However, if you want them to be built automatically, just erase that line from the JSON.
Have fun!
UPDATE:
Now with winter frames! Yeah, that was fun. A special gift for certain greedy persons around here

I highly suggest a redownload to those twelve people who have downloaded the plugin already. Just replace the old folder with the new one.
