Run multiple scripts with one click?  Python scripts can call one another, so you can create a sort of runner script.

import poser

poser.ExecFile("Runtime:folder:script1.py")
poser.ExecFile("Runtime:folder:script2.py")
poser.ExecFile("Runtime:folder:anotherscript.py")

The above lines between the # signs should work as a script if saved as a .py file.  Change the paths as needed, using Poser's Mac-style relative Runtime paths.  As far as I can tell from my own experiments, the colon before "Runtime" should be omitted for these, although I'm not sure why....

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
