I am not talking about the Orion and Faustus nameplates which are made through Blur multiple Layers, that's tuturial is excellent but it doesn't really help me.
What I mean are the Leviathan nameplates, also used for Fenris/Deimos/Hecate models. The RGB layer uses white letters with a Black Background, while the Alpha Layer uses a Black background also (means 100% transparent), bu the the letters have a 10% transparency. That's what I don't know how to do, I understand it, but I can't really do it.
RGB Channel:
Alpha Channel:
The only way that I can think of doing this, is to save the the same image as a Bitmap but with the Letters at 10% Oppacity, then I use the option to load an Alpha Channel from a Bitmap. That way seems to work, but it is wrong there should be a simple way to do it.
