Further information: The dials do not stack. For example, if you create a grid for [-90,-45,0,45,90]x[-30,0,30], the [45x30] dial will be zero if the actors are bent to [90x30]. But of course you could start by creating a JCM for [45x30], and slave this to both the [45x30] and [90x30] parameters. If [90x30] needs an additional correction, you can develop a further JCM and also slave this to [90x30]. The JCMs that you create, should ideally have their own naming schema and individual master parameter. That makes the reuse and the decoupling easier. I have not really tested these JCMs grids, its hard to predict if they work in other applications, lower versions of poser, if poser saves the setup properly in scene files or libraries, ... bla bla bla....
