So, I've figured out how to do fancy texture manipulations with just the traditional material nodes, no newfangled Cycles stuff. Once again, that does not necessarily mean this will work in Poser Pro 2014 because the workings of those nodes may have been changed in the meantime. But at least there's a chance...

(Kaleidofemme, lol!)
