NPC's with "blackface"

[jmwhalen1000]

2 of my NPC's (so far) have "blackface". Ysolda and Saaid in Whiterun. There bodies are normal, but there's a dstinct line at the neck and everything above is a dark bronze color. I know this has probably been asked and answered, but I'm new at modding, so please be patient with me. I'm using Vortex and there are 4 "missing masters" messages, 2 are missing sexlab.esm, 1 is missing ELE_SSE.esp, and 1 is ELFXENHANCER.esp. I entered those masters in the search bar on Nexxus but no luck. I don't know where to find them.

I'm running Skyrim SE (V: 1.6.1170) from Steam. I am not getting any error messages at start up. 

Any help is greatly appreciated. Thank you.

IIRC, this is usually, if not always, caused by a face replacer being overwritten by an earlier version, or an esp-fe version not being able to find the headpart items it needs to display the face.  Sometimes it seems really hit-or-miss.  I have removed an NPC mod or two that I could not find solutions for.  You could try to search this forum for 'dark face bug' or 'black face bug' to get more information.

A 'Missing Master'  message should tell you which mod needs that missing master.  

That said,  'Sexlab' is on Lover's Lab(VERY NSFW site), not Nexus.    

ELFXENHANCER.esp is part of this mod

ELE_SSE.esp is from 'Enhanced Lighting for ENB (ELE)' mod.   Which for some reason has been removed from Nexus.   But there is a replacement

Now, about black faces - it generally means that there is a mismatch between the actor base record in the plugin, and their head mesh.   Most typical reason: you have two visual replacers, but one has its files in a .bsa archive, another has loose files, and the replacer with .bsa has its plugin loading last.    Another case - you have a visual replacer for an NPC, but another mod also overrides that NPC record.

This is best diagnosed via SSEEdit

You start it up, have it load ALL active plugins, then expand 'Skyrim.esm' - Non-Player Character(Actor) - and look for 00013BAB - Ysolda  (00013BA2 is Saadia).   See which plugins override Ysolda's record and in what sequence.   Once you know that, the issue can be fixed.
