Converting mod to esm broke the mod.

[TheFaeranBlade]

I wanted to give Veronica custom hair from "Nouks and Apachiis hairstlyes" (http://www.nexusmods.com/newvegas/mods/50296/?), so I converted it into an esm using FNVEdit and changed Veronica's hair in the GECK. When I loaded the game back, both Veronica and my player character had vanilla hair (The Unsettler). Does anyone know what might cause this?

I don't really see a reason to convert it to .esm
Did it not work as an .esp?

You can't add a hair from another esp into your own mod for an NPC. The file containing the hair resource has to either be an esm or the hair has to be defined in the same mod that you are changing or defining the NPC in. In other words, if you have a mod called MyVeronicaMod.esp and you have a hair resource that you want to use in HairResource.esp it's not going to work. If you have a mod called MyVeronicaMod.esp and the hair in an esm like HairResource.esm then that will work fine, and your mod will now depend on that esm file. However, if you have HairResource.esp and you edit that mod and change Veronica in that file, then that works too.

 

As for the OP, the problem is that you have a definition of the player in your save file and also a definition of Veronica in that same save file, and they both point to a resource that no longer exists (since you changed the file to an esm, it's effectively a different file now). You might be able to fix it by removing all of your mods that affect Veronica and your player's hair, making a save game of that, then adding the new esm and loading your save. Or just start a new game.
