The d3d script is working fine in PoserPro here.

Do you have it installed to the  :Smith Micro:Poser Pro:runtime:python:poserscripts folder?

If it is in the correct location then open PPro and load the figure that has the dials you want to hide or unhide.

Press SHIFT>CTRL>O to open the Python Scripts window

Select an open slot in the dialog and navigate to the location of the UnHide Dials.py to load it for use.

Select the actor containing the dial you wish to hide or unhide then click the UnHide Dials button in the Python Scripts window.

This opens a dialog that has hidden dials in the left column and visible dials in the right column.

Select the parameters you want to manipulate using standard selection methods and click the appropriate button SHOW or HIDE depending on what you are trying to accomplish.

Save a new CR2 with the changes to the dial visibility.

If you have followed all of the above steps exactly and it still doesn't work then you have some other issue occurring.

Please post any error msgs that pop up if the problem continues.
