A command line argument is a parameter that is added after the executable name to pass information to it. They are a basic OS feature.
For example, instead of just executing "xEdit.exe", it is started as "xEdit.exe -sse" so it starts in the Skyrim Special Edition game mode.
In Windows, they are typically added as part of a Windows shortcut.
Refer to the manual of the mod manager how to add executables and command line arguments for them:
- Mod Organizer - Arguments field
- Vortex - Command Line field
Since TexGen/DynDOLOD are based on xEdit, they support the same Command Line Switches of xEdit. Below is a list of the most useful ones in regards to paths:
-[Game Mode] for example -tes5, -sse, -tes5vr, -enderal, -enderals, -fo4, -fo4vr -o:"[path to output folder]" for example -o:"c:\Output\" -m:"[path to INI folder]" for example -m:"c:\Users\[USERNAME]\Documents\My Games\Skyrim Special Edition GOG\" -p:"[path to plugins.txt]" for example -p:"c:\Users\[USERNAME]\AppData\Local\Skyrim Special Edition GOG\plugins.txt" -d:"[path to Data folder]" for example -d:"c:\GOG Games\Skyrim Special Edition GOG\Data\"
Replace [USERNAME] and the INI and Data folder paths accordingly for the actual setup.
Use copy and paste to avoid mistakes, like adding extraneous spaces between the command letter, colon and beginning double quotes.
