Is there a Python script to get rid of extraneous material zones? I seem to have accidentally answered yes to the dialog asking if I wanted to add the zones on one of my figures. I can easily edit the CR2 if necessary, obviously, but I'd rather just do it directly in Poser if possible, via Python.

Also, is there a script that can directly copy one character's morphs (or rather a subset thereof) to another in the same scene?

Poser Pocket Knife has the tool required to remove redundant materials from a figure.

The Poser Tool Box has the option to transfer morphs.

Hope that helps.

Copy the morphs , or the morph settings ?
The quick way is to save a pose file containing the morphs , and apply it to the other figure. If you save a pose without morph data first you can restore the figures position.
