I installed the latest update of NGV8 but when it is applied and the materials updated with the script the colour doesn't match. How do you get this to work? It's on Bluejaunte's Gaia. https://postimg.cc/qgm8MH9d
I often have trouble with NGV8 and 8.1 even with the update. Sometimes I have to turn off one of the gen effect layers. Sometimes I just save the torso (body) shader to the library and apply it to the vag and anus, then reconnect the correct textures, bumps and normals. Try the layer effect thing first.
EDIT - You don't have a geoshell on do you?
