Hehe my question was actually what PML does, not how. I mean, does it help exporting models from Poser, and then import them back? What exactly would it do?
Oh, LOL!
It's all python scripting. My workflow is as follows:
Load the model
Load the clothing, conformed
Pose the figure (and clothing)
export the model using PML
export the clothing using PML
save the scene file (you'll need it for when you re-import the morphed models)
Open the modeler and create the morph(s)
I load the posed figure so I can avoid intersections when creating the morph, etc.
Load the clothing.
Create your morph using your modeler's toolset
Export the morphed object file
Return to Poser
Load the saved scene
Using PML, import the morph objects as a FBM
(You will have to load the original exported object, THEN the morphed object. Which is why the scene file save is important. PML won't know what to do if not using the same posed object files when you re-import.)
Save the CR2 with your new morphs.
Here's an example of an exported (posed) object from PML in the modeler.
