Hi Doogerie. This info was posted by some dude named Ren_Cloudkicker on Steam. I'm reposting it here for ya:
Here is the breakdown of the DLC you might have and how to get it in the game. This example is adding it to your default resources. This means, it only works with newly created projects... since when you create a new project, it imports from the default steamapp folder. To add to your current project, you might just need to add these to your local folder.
-------------------------------------------------------------
DLC folder
\steamapps\common\RPG Maker MV\dlc
Subfolders...
BaseResource (merge folders audio and img with \steamapps\common\RPG Maker MV\NewData)
Cover Art Characters (merge folders with \steamapps\common\RPG Maker MV\NewData\img)
except BMG
- Bmg (place contents in \steamapps\common\RPG Maker MV\NewData\audio\bgm)
- Characters
- Faces
- Pictures
- Sv_actors
- System (note: there is a file names Weapons3.png You may already have that file but it is different. Rename it to Weapons4.png and add to folder.)
Essentials Add-On
- BGM-MP3 (place contents in \steamapps\common\RPG Maker MV\NewData\audio\bgm)
- BGM-OGG (place contents in \steamapps\common\RPG Maker MV\NewData\audio\bgm)
- Bonus- Icons (place contents in \steamapps\common\RPG Maker MV\NewData\img\system)
- Bonus- Titles (place contents in \steamapps\common\RPG Maker MV\NewData\img\titles1)
- Facesets (place contents in \steamapps\common\RPG Maker MV\NewData\img\faces)
- TileSets (place contents in \steamapps\common\RPG Maker MV\NewData\img\tilesets)
KadokawaPlugins
- .js files (place contents in \steamapps\common\RPG Maker MV\NewData\js\plugins)
RPGmakerWeb_pluginsPlugin folders containing .js files (place contents in \steamapps\common\RPG Maker MV\NewData\js\plugins)
-------------------------------------------------
Hopefully this helps and is clear enough to understand. Now when you click to add a plugin, the whole list should be there for you. The other content like characters and tiles will show up just like the default stuff.[*]If you don't want to import a huge database everytime you start a new project, then just add these folders to where you have your project saved.
