SCHEDULE ONE NATIVE PREFAB LOADER
This mod adds no content on its own. Install it because something else asked for it.
OVERVIEW
Native Prefab Loader is a small dependency mod. It reads content packs out of Mods\Packs and hands them to the game as normal Schedule I content. It allows Unity serialized assets to be loaded as vanilla items, without duplicating items in C# and other workarounds.
Everything I release for Schedule I is built as a pack, and every one of those packs needs this loader installed to do anything. If you downloaded one of my mods and it came with a file named ScheduleOne. NativePrefabLoader. Mono(IL2CPP).dll, this is that file.
Items loaded this way are ordinary game items. They show up in shops, get bought, placed, stored, saved, and replicated in multiplayer through the game's own systems. There is no separate inventory, no custom shop, and no parallel save file and no C# complexities. Everything is serialized in Unity the same way vanilla items are exported.
There is no menu, no config file, and nothing to turn on. Install it and forget about it.
WHAT IT IS FOR
-
[]Loading the content packs that ship with my mods[/]
[]Letting a pack add new items to the game[/]
[]Letting a pack replace or change an item the game already has[/]
[]Keeping every one of my mods on one shared dependency instead of one DLL each[/]
If you are not running a mod that asks for it, you do not need it.
REQUIREMENTS

[]Schedule I[/]
[]MelonLoader[/]
INSTALLATION
1. Install MelonLoader
Install the Mono version of MelonLoader for Schedule I, then run the game once so the Mods folder is created.
2. Copy the loader in
Open the archive, go into the Mono folder, and copy its Mods folder into the Schedule I game directory. Merge when prompted.
The default Steam location is usually:
C:\Program Files (x86)\Steam\steamapps\common\Schedule I
If the game is installed in another Steam library, use that Schedule I directory instead.
3. Add your packs
Content packs are .unity3d files and go directly in:
Schedule I\Mods\Packs
Create the Packs folder if it is not there yet. Do not nest packs in subfolders.
4. Verify the files
Schedule I\Mods\ScheduleOne. NativePrefabLoader. Mono(IL2CPP).dll
Schedule I\Mods\Packs\SomePack.unity3d
5. Start the game
The MelonLoader console will report the loader version and the Packs folder it is reading.
MULTIPLAYER
The host and every player who connects should run the same loader version and the same packs. Mismatched packs between players will cause missing or broken objects for whoever is short one.
UPDATING
Replace ScheduleOne. NativePrefabLoader. Mono(IL2CPP).dll with the newer file. Keep one copy only.
My mods bundle a copy of the loader in their own archives. If a download hands you an older loader than the one you already have, keep the newer one.
UNINSTALLATION
Back up your save first.
Pick up or remove placed modded items before you pull the loader, or the objects they were tied to will be gone when the save loads.
Delete the pack files from Mods\Packs, then delete:
Schedule I\Mods\ScheduleOne. NativePrefabLoader. Mono(IL2CPP).dll
Leave the loader alone if any other installed mod still uses it.
TROUBLESHOOTING
Nothing from the pack shows up in game
Check that the .unity3d file is directly inside Mods\Packs and not in a subfolder, and that the loader DLL is directly inside Mods. Then read the latest MelonLoader log for the loader's startup line and the count of items it accepted.
Back up your saves before installing or updating any mod.
