Quote - I'm trying the Spawn Morph Target, but when I set its dial to 1.000, the body parts is like, overmorphed or something. Its all distorced, even though I've cleared the custom morph already. Do I have to do this on a zeroed figure?

Spawn Morph Target will create a morph which contains deformations from any morphs or deformers which are active on a body part when the command is run.  This can include FBM or JCM morphs.  If you're trying to use the process on an actor with joint controlled morphs, the figure (or at least the actor itself) should probably be zeroed.

A benefit of using your file-editing process would be that this sort of problem won't crop up.

One of many tools that Poser could really use is any kind of option to restrict what deformations contribute to a spawned morph target, IMO.

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.
