The script will prompt with the current figure name for a yes/no response and it will list the generated names for the pose and camera. That name is the figure or camera name with a 4 digit frame number appended.

The path to the correct folder is added to the filename for the save.  

Amending the script to prompt for a project name would not be hard , and automatically creating the folders isn't difficult either. There is no way I know of to get the pz3 file name from in Poser.

Doing all the figures is a simple loop, props are a little harder but doable.

The current script does all frames , not all keyframes, so If you build scenes at 10,20,30 etc it will need to be changed.
