I'm using a mod that adds/makes certain npcs recruitable companions (https://www.nexusmods.com/fallout2/mods/70?tab=posts) and I was wondering how I would go about finding out the PID for the companions to add to fo2tweaks.ini. I realise this might be better asked somewhere else since it's not purely fo2tweaks related but I figured I'd ask here first anyway. Thanks for your time!

I don't have that file, I don't even have the second data folder .

It is likely packaged inside one of the dat files. Depending on your platform, it could be upu.dat, rpu.dat, or something else.
For UPU or RPU, you could grab the file from the corresponding repos.

I ended up looking at party.txt in the mod for the pids. Do I need to add the levelup pids too or just the base version of the follower?

Just the base.

Thanks for the help!
