hi ,
small question about the basics 
you said:
This guide will take into consideration that you have ADK installed and working and have loaded up the island at least once.
then select save as and navigate to your new mods folder and save it as the folder name
Now lets load up the island and copy over what we need to make a working weather/day&night cycle as well as the waterplane, simply CTRL+Click then CTRL+C to copy then CTRL+V to paste (you might have to take a few files at a time as it sometimes wont copy/paste if you select them all at once)
its the: then select save as and navigate to your new mods folder and save it as the folder name…i dont understand…
so you make a folder: named map name in mods dir…ok
then load up he island and copy the items…then paste them into that folder??? but it wont let me…
or do i have to make a folder, then create new level in it and paste the island items inthere??
then worldcompo to create new sublevel for the landscape??
or vreate a new landscape and put the folders inthere? but then is the landscape persistent…
bit stuck help pls
