I have a ESP file with only NPC records and now I want to import the face geometry changes, hair style edits etcetera into my Bashed Patch without activating the ESP itself. It's a rather dirty ESP I'd prefer not to clean manually, and it's also not mine so I wouldn't know where to start therefore the whole merging of records into the Bashed Patch. So I went on and tagged it NpcFaces and NoMerge in hope it would work that way seeing how that's what filter mods are tagged in Oblivion. Turns out it didn't, and the ESP remains a master of the Bashed Patch. Can someone please point me in the right direction? Or is this even doable given that the tools we have here are outdated compared to Oblivion?

Thanks in advance.

Okay, so I experimented some more, and found out that this method indeed is working with our current tools, yay. So it's something in the mod. The ESP in question is New Vegas Redesigned which I omitted any records from and then turned it from an ESM into an ESP myself. Then I took another New Vegas Redesigned ESM and removed any NPC records from it and used it as a master for the newly created ESP. The lore version works, but then again it has only 6 records, the main file doesn't. If I remove any (intentional or not) changes regarding AI packages, SPECIAL stats it will work, too, or am I wrong?
