(made to fit with my black and red vaultsuits)
it has custom alpha, specular and normal maps
to install just drop the contents of the zip into your Fallout 4 install folder.
if you have not done so already you need to change a line in your ini file
(Documents\my games\Fallout4\Fallout4.ini)
search for the line that reads sResourceDataDirsFinal=STRINGS\
and change it to
sResourceDataDirsFinal=STRINGS\, TEXTURES\, MUSIC\, SOUND\, INTERFACE\, MESHES\, PROGRAMS\,
MATERIALS\, LODSETTINGS\, VIS\, MISC\, SCRIPTS\, SHADERSFX\, VIDEO\
you can change the armour to any colour you like by simply changing the colour of the file
CombatArmor_pallette_d.dds
note that most (if not all) combat armour worn by npcs will also sport this texture.
