Hey there!

This is a conversion of the Dark Disciple to UNP body.

First of all, I did this conversion for personal use. There are flaws, is not perfect as I would like.
I'm not a 3D modeler/designer, actually I don't even how to launch Blender. :P

But I decided share with everyone this conversion because no one did it yet.

Requirements:
UNP Body (really?)

Dark Disciple armor by BetterBecause.

Installation:
Install Dark Disciple by BetterBecause
Install my mod overwriting the original files

-
Known issues:
As mentioned above, the mesh have some imperfections.
I have not modified hands and feet meshes, then they will not fit perfectly with the body armor.

*Bonus*

Accidentally, I found 3 bugs in "darkstandalone.esp" original file, created by BetterBecause.
When BetterBecause make this file, he forgot to rename the file first person nif file.

You can fix this manually - is easy. :)

Open DarkStandalone.esp in TES5Edit or CK.

bug 1:
Look for FullLeatherGlovesDD

Armor\Studded\Female\1stPersongloves_1.nif change it to  armor\BBs\catsuit_hands_1.nif

Bug 2:
look for FullLeatherGlovesCD

Armor\Leather\Female\1stPersomgloves_1.nif change it to  = Armor\BBs\catsuit_T_hands_1.nif

Bug 3:
look for FullLeatherCuirassCD

Armor\Studded\Female\1stPersonbody_1.nif change it to armor\BB's\Catsuit_T_1stPerson_1.nif

As said, these 3 bugs are present in darkstandalone.esp file, unfortunately I can't upload this file fixed.
You will have to fix it manually.
