It's a shame we're all so used to morph packs that the face room gets ignored.  I agree with takezo3001 that's it's a great tool and wonder what it would be like if DAZ figures were also supported, but I guess that will never happen :(

Anyway, here's Sydney in default state and with three variations just using the faceroom for both morphing and texture tweaking.  I think I'll go back and try the new morphing brush for more details.   

The only problem I had was Poser giving me an out of memory error  when I tried to generate a second hi-res texture.  I had to close Poser and restart it for each of the three texture mods.
