I don't know if this is a figure or 2 props. Anyway, you will always be able to move the jack from the stand, because it's a child of the stand (the parent). What you can do is this. In poser, double-click the trans dial NAMES for the jack. In the dialog box that opens, set the maximum and minimum limits to 0 (zero). You'll want to either leave the Y trans alone, or work out the distance it has to rise, and set that as the limit. For example, when the jack is fully raised, if the Y trans reads 0.100, then set that as the max and zero as the min. After you've resaved the whole thing, open it in a text editor, find each of the 3 trans channels (search for Xtrans, Ytrans, etc), and change the line 'force limits 0' to 'force limits 4', then resave it. When you reopen it in poser, the jack will raise to the top, then stop, and it will not move in any other direction. 'How is it possible to make a custom parameter dial for the jack part to move just up and down' When changing the limits in poser, you can also rename the Ytrans dial to 'up/down' or whatever you want. Other than that, the only way would be to export the raised jack as an obj, then add it as a morph target. But this is pretty klunky and pointless. It adds to the file size and doesn't do anything that the Y trans dial doesn't do. mac PS Whether it's a figure or 2 props, all the above still works.
