Tips: Portable Install
OpenMW 0.48 added the ability for a "portable install"; that is: one where all the cfg files and related things that normally live amid your user documents instead live in a separate folder of your choosing.
This can be handy for playing with total conversion mods such as Arktwend or Starwind, where you may want to keep these files separated from your normal files for playing Morrowind.
To use this feature, create a launcher for OpenMW with a couple of specific arguments as follows:
# Linux/macOS openmw --replace=config --config ~/games/StarwindCfg --user-data ~/games/StarwindCfg # Windows openmw.exe --replace=config --config C:\games\StarwindCfg --user-data C:\games\StarwindCfg
In order for the game to launch, you need valid
settings.cfg files in the folder you specify. You could copy those from the normal location and then edit them as needed.
This specific example is for Starwind, but you can name the destination folder anything you want.
