I want to use a "mod" that makes your camera stay on left side in third person even if you are in combat and i have to edit skyrim.ini with: w

[Camera]
fOverShoulderCombatAddY=0.0000
fOverShoulderCombatPosZ=-10.0000
fOverShoulderCombatPosX=30.0000

But that doesn't change anything in game, am i doing something wrong?

What mod?

Make sure the changes are sticking.

Which skyrim.ini are you editing? You need to modify the one in Documents/My Games/Skyrim

Basically it's not really a mod, i just have to edit the file skyrim.ini and put the commands i posted previously, but that didn't change anything, i'm also running the game using Mod Organizer and launching SKSE.

That's the one i edit but nothing happens

If you're using MO then you must edit the ini from inside MO.

Mod Organizer had it's own ini files? i didn't even know... i edited them and now they took effect in game, thanks.

MO allows people to group mods installations into profiles. That way you can have separate mod collections without having to reinstall Skyrim.

Each profile comes with its own set of ini files. MO shows Skyrim the ini files it uses. From Skyrims perspective they are the ini files from the my games directory. As far as it knows.

If you wanted to use the My Games ini files you would start Skyrim through the launcher.

From the MO nexus page:

Mod Isolation (1):
------------------

What mod isolation means is that each mod is installed into its own directory outside the actual data directory.
Through some magic MO then shows the game (and any other 3rd party tool that works on the data directory) a "virtual"
data directory that is a merger of the actual data directory and all the mod directories.
This way no file ever get overwritten when you install a mod and your data directory can remain in a vanilla state.
You can simply change the "installation order" of mods from the gui and deinstall or temporarily deactivate one
without breaking other mods.
