Hello everyone I had such a wonderful experience with these utilities I felt like to share it, use to have problems with nexus mod manager and sometimes unable to solve them my game will get corrupted and I will have install the game over again but with mod organizer it does not touch your game and your data folder stays clean, doing manual install is not my thing because for me something can still go wrong. Merge Plugins xEdit Script a skyrim plugin that works with fnv and fo3 I have merge all millenia weapons and other weapon mods bring my load other from 140 to 69 I think these utilities will help some with problems with there game and I do recommend the switch opinions is nice from others who use these utilities. If your game already runs good for you I see no need for you to switch for me it is a must have I use it for skyrim,fnv and fo3.

There is a specific tool for quick use for merging files called FNV Plugin Utility. On my phone atm so can't link.

I would have to agree with nick85. I just spent the weekend installing FNV through mod organizer and using the EssArrBee STEP installation guide (using most of the mods as a base but not all) and I have to say i'm finding my game much more stable. Plus Mod Organizer has some powerful utilities in it that, if you know how to use, can make installations and customization a breeze. Only downside is that some mods have to be installed though a FOMM fork but as I said before, EssArrBee's guide tells you exactly how to do this and for which mods (usually only UI modification mods) which makes it easy.

I know this is an old topic, but I for the life of me can't get merged plugins through FNVEdit to work correctly. I tried doing it with Dragbody's armor packs, and while the actual process of merging the plugins went very smoothly (and I followed the instructions to the letter), when I launched the game all the textures and meshes for his armors were missing, instead with that fatal red exclamation point in place of them. What am I doing wrong?
