M9.esp
# C:/Users/steamuser/AppData/Local/Fallout4/Plugins.txt *M9.espQuick Test
The M9 pistol mod is a really good test since:
- it has custom assets
- it use a .esp
- it can be added from the console, in a new game before reaching the vault
Install Mods
Mod Organizer 2
NOTE:
installation failed on proton-5.x, but after a reinstall on proton-experimental everything works!
- download: - run: protontricks -c 'wineconsole cmd' 377160 - run: | cd Z:\home\will\Downloads Mod.Organizer-2.4.2.exe - install: - perform a 'portable install' of MO2 - skip nexus linkNOTE:
MO2 works by running the game from a virtual filesystem with your mods layered overtop of it.
In the rightmost pane's Data tab, mousing over a file will reveal the virtual filesystem location.
Once everything is satisfactory, you can copy this virtual filesystem and run it directly from wine?Run game
protontricks \ -c 'wine /mnt/storage/games/steamapps/compatdata/377160/pfx/drive_c/Modding/MO2/ModOrganizer.exe' \ 377160Overlayfs
NOTE:
This didn't work for me. The .esp displayed as loaded, but the content wasn't present in-game.
I tried read-only, read-write, making the various .ini files read-only it just wouldn't work.
Plan Updates
Steam likes to auto update programs. This is problematic for mods that make use of F4SE (which is tied to a specific release of fallout4).
Configure Steam Updates
Set steam to update on run, or limit updates to hours computer will not be in use (ex. 4-5am).
Keep Previous Updates
- Find what version of Fallout 4 you are currently running.
- Copy and paste a copy of Fallout4.exe and then rename the new copy to Fallout4-<version>.exe
- Whenever Steam updates Fallout 4, simply rename the new Fallout4.exe and then change your older copy to Fallout4.exe.
- When the F4SE team is able to release an update, download the new F4SE version and rename the new patched executable back to Fallout4.exe.
NOTE:
This is true, but Fallout changes more than just the .exe in updates (but less than the whole application).
