Quote - I also wonder if there is a trick to arrange parameters into groups with python. Did not find it yet ;(

The only thing I can think of would involve using Python to edit a cr2 or pz3, or possibly creating a custom pose and loading it.  I know a pose which loads a pmd morph set can overwrite existing parameter dial groupings, but I'm not sure whether a pose alone can do that, minus the pmd-loading part of the process.  Either way, since loading groupings through a pose would fully overwrite all existing parameter groupings for an affected actor, the pose would need to be carefully tailored for each case by the Python script.

(Also, you explain this stuff better than I could!  :lol:  You're working with more complicated matters than I tend to tackle.  JCMs and their ERC settings have always confused and frustrated me terribly.  :scared:)

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.
