i think that these settings are very important for layered texturing
but if they are not gone where will i find them???
Theres 2 separate nodes your talking of layered shader but you refeer to layered texture.
layered texture and layered shader are different nodes. Since shaders allready incorporate a blending mode they dont need a dropdown, in fact they can make their own as convoluted modes as you like. The primary difference is that layered schers allow for COLOR transparency transfeers just like shaders use. Whereas layered texture just uses on channel alpha (since it is just alpha it needs a blending mode to get all the cool effects color trnasparency takes care of that need in different way)
Please note: even in maya 2009 theres 2 nodes the mel template just makes up a slight lie to you
