Foliage override keys, I've used and made them but to the life of me I cannot remember what folder I stored them in to active it. What is dose is in the grid editor where the list of islands are select the island you want and edit island. There will be a drop down menu called foliage override, and I believe your allowed 5 per island, and it works for critter too. I stumbled across it by accident and been banging my head every since trying to reduplicate the process I went thru but I know you have to make a folder and name it FoliageOverideKeys but I can't member where in the grid editor files I had it.
