Find the <Mod Path> that the game will use.
There are two different folders for Rebellion mods, the released folder with version, and the developer folder with version.
Developer EXE access --> ...<Mod Path>\Mods-Rebellion vX.XX Dev
Sins Mods are very specific to version and expansion type
vX.XX is the version of Rebellion. There may be multiple folders for different versions of each upgrade. Place the mod in the most current version folder only if the mod was made for that version. Older version folders or the mods in them are no longer used by the game.
Create a new directory here. The name of the directory will be the name of the mod. You must restart the game to see any new mods. You won’t have to restart the engine to change a mod, just to create a new one and have it appear in the list.
Use a text editor to manually add what Sins loads on start-up.
The enabledModName will look for the dirctory named in quotes inside the <Mod Path>.
Mods are meant to stack only if they are designed to.
