Wtf, I was told attach armature doesn't work for rigging helmets....but it does since I just did it.
which means you can make chainmail coifs, a gasmask with an oxygen line leading to a tank
maybe even fix the neck sticking out problem (although that would take some time and might not even work because it isn't a normal object....I'll test it out since it has bothered me from day one.)
narp the skins file doesn't seem to recognize itp_attach_armature, but still works fine with helmets.
