Alright Spy I found something you were looking for:
Tree RepositoryHere is a download that will contain:
1. Three folders with schematics, which is the actual repository you can use for various third party tools and commandline editors [i made a short tutorial how you can use these schematics in worldpainter, see down below]
2. A folder named "Tree Templates" this is the world file with every tree which is in the repository on a grid, with the name. So you can single out trees you want or don't want.
3. Three folders named "Test Island", those are the islands i made to test out the trees for worldpainter brushes, and are the islands i made all the screenshots on which you can see in the reel. Feel free to use the islands for anything, they are survival playable, and cheats are enabled so you can easely switch to creative for creative projects.
Now I want to know, can the schematic files be imported into the server world with something like world edit? Or do they manually have to be imported via something like MCEdit? If it's the later I can put them all in via MCedit and then give you the world file that can be uploaded back to the server. However I need to know which trees you would want, so I don't have to copy and paste all of them into the world.
Personally I'll be using North American trees to use on the north and Rise area. And Alois will be primarily populated with European Indigenous trees.
