How to create a mod like this? (patch type mod)

[Phoenix7]

YES I did read the sticky!

I was wondering how I would go about creating an esp like Lazy Monk's Alternative NPC faces for Integration: TSL I'm thinking of offering a plugin that does the same thing, but just tidies up the faces, not overhauls them completely. Basically keeping them the same but fixing things like huge noses, impacted eyes, etc. I would just edit Lazy Monks mod, but seeing as how I'm refining the original faces I need to edit them and not the edited versions.

I know how to make a mod, I just have no idea how to make a seperate esp file that only makes face changes, for a mod that alters a mod, that has several esp masters. I know in order to edit Integration I have to use Wrye bash to ESM-ify LAME and RBP. I just have no idea how to make seperate, isolated "patch" esp's that only make the appropriate changes.

Basically I want a file, or to make a file exactly like the one I linked to without face changes.... God, I hope that made sense.

EDIT:

I tried ESM-ifing all the required mods, making my changes and then saving my changes it asked me to name my new esp file, but it keeps failing to save so I assume it must be something else.

I know how to edit mods I just don't know how to make a new esp, and make changes that that using other mods as masters. I also tried taking the blank esp that comes with wrye bash and loading it as the active file along side the ESM-ified: RBP LAME and Integration. Trying to save that made the CS crash.

EDIT:

Also a related question What happens if you ran a mod like this with three duplicate masters? Like it had three master files and they all pointed to one esp... A version of integration that is isolated to one esp is being worked on, so essentially RBP, LAME, and Integration all in one esp file.

Everything keeps the same FORM IDs andsuch so you can use other mods that require RBP, LAME, or Integration so long as you use wrye bash to change the master to the integrated file. It gets kind of complicated with mods that require all three mods because then there's three masters all pointing to the one esp. This is the case with the unique clothing add-on, Lazy Monk's faces add on, and probably just about any other of the Integration add-on mods/patches. So would the three masters work, or is there an easy way to delete the two redundant masters, or what?

LazyMonk told me how to do it. Basically make the two esp masters into esms with Wrye bash. Edit Integration. Open TES4Edit, select the NPCS who's face I edited, and "copy as overwrite" to a new file. Then of course go back into wryebash and turn the esp masters back into esps. That seems to have worked.

Also according to bg2408:

- Making a patch file: As strange as it sounds, you'd need to esmify everything and in addition to change the faces you'd need to move a tree (or something other in the landscape). Otherwise the CS would crash on save. Strange little bug there is.
