I agree, it is certainly problematic to get in and out of each layer's
alpha
channel. I don't think that there is any way around this: you must save
multiple textures to get all the channels you want for a complex material
as
GIMP doesn't make materials and has a limit (as far as i know) of 4
channels.
FWIW one of the nice new features of the Unreal Tournament 3 game editor
is
that you no longer have to use alpha layers for specularity masks etc.,
now
you can use any layer of any texture although even here I believe that you
can't use materials within materials and each component texture can only
have 4 channels.
