If you've never used World Edit schematics before, this is the post for you!
Install World Edit. I use Fabric, but it will also work with Forge.
Need help installing one of these? Watch the applicable tutorials:
Locate Schematics Folder [%appdata% -> .minecraft -> config -> worldedit -> schematics]
Unzip the newly downloaded schematic.
Paste the unzipped file into the schematics folder.
Open your desired Minecraft world.
Type in the command: //schematics load nameoftheschematic (For example: //schematics load MossyCottage) The name must be exact.
Find a suitable location, the schematic will be pasted based on where you're standing.
When ready, type in: //paste -e
The -e part is VERY IMPORTANT because it will allow you to paste all of the item frames with all renamed items placed inside of them. Any item frame textures will not load if you do not include the -e.
If you made a mistake or place in the wrong spot, type in: //undo
If you wish to rotate your schematic type in one of these commands:
//rotate 90 (rotates 90 degrees clockwise)
//rotate 180 (rotates 180 degrees clockwise)
//rotate 270 (rotates 270 degrees clockwise)
