Just a cross-connection with the Poser 7 threads. DAZ are using something that sounds like ERC tech, with several different parameters controlled by one dial. The Reason 7 list included a reference to improvements in how this can be set up. Quoting: Flexibly increase or reduce the value of any parameter in your scene with Dependent Parameters. Using Dependent Parameters in your files allows you to modify multiple morph targets, deformers or any other parameter using a single, master parameter dial. Now with Poser 7, you have much greater control in defining the ways that your parameters interact as your figure is adjusted. I can see there being a P7 .cr2 which takes advantage of such a change, and a more limited version for older software. Does this mean a .cr7 file? What this "greater control" might be, I have no idea.
