Those of us with PhotoShop could easily add the extra channels; I'm not sure what other programs could do. The main trick is to have Poser read the combined file. (I'd imagine that the Materials Selection Menu would look the same, but we'd be loading channels instead of separate files, and could still fidget with the dials.) We do not want to go the CMYK route. That is for printers, and limits the "safe" colors to those printable with real ink as opposed to what we can see on a monitor. The blues and purples will suffer terribly. Carolly
