How to add fangs to an NPC in Custom Mod?

[DevilFireSmile]

Just installing existing mod isn't an option - I'm doing custom mod to avoid incompatibilities with mod I already have, for personal use.

 

Want to add fangs (teeth) from either "Fangs and Eyes" or "Fangs and Eyes - Serana" mod to vanilla Serana. 

First mod contains only eyes .nif's and mouthhumanchargen.tri and mouthhumanfchargen.tri, the other - full .nif for Serana's head, but I don't like her new face there.

How can I apply these .tri files or somehow copy teeth from "BVFE - Serana" to Serana's .nif I currently use?

UPDATE:

Solved it.

If someone want to use "Fangs and Eyes - Serana" but with her vanilla features, using nifscope open 00002b6c.nif from the mod (need to use BSA extractor) and  a copy of 00002b6c.nif from Skyrim's dawnguard.esm. (extract it into your "Fangs and Eyes - Serana MO2 folder, to be safe don't edit the original)

- In first nif, under BSFaceGenNiNodeSkinned, right click on FemaleMouthHumanoidDefault, the Block>Copy Branch;

- In second, right click on BSFaceGenniNodeskinned, Block>Paste Branch;

- Delete the old "FemaleMouthHumanoidDefault.

 

Now modified vanilla .nif, placed in your mod folder, should overwrite Serana from "Fangs and Eyes - Serana", which will give her original face but with better fangs (and eyes, if using standalone "Fangs and Eyes").
