Missing facegen files

[runsbuns]

I have a npc apearance overhaul mod with some missing facegen files, dont know exactly which or how to find out . So I wanted to ask:

If I wanted to export/generate all the facegen files from the esp(there's alot), can I just load the the mod in CK and export them all without going through each one? and if so how do I do it?

Load esp in CK.

In Object Window -> Actor

Select all the NPCs you want to face gen.

Hold Ctrl and hit F4.

Click Yes when prompted.

Done
