Setting limits using a pose: The pose needs to include the morph listing, with forceLimits set to 1 and min and max set to the limits.  It's pretty simple, really.  :D

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.
