Brief overview of the process:

To create a morph you need to export your skirt model as obj at 100% scale and import keeping scaling and vert order the same into your modeler. Make the shape changes for the first morph. Then export your morph obj calling it something like "skirtwind-left"

its critical that you dont add or remove any vertices for your morph to work correctly, your just changing the shape.

Now export as obj keeping scaling and vert order the same. Go back to Daz Studio and select your skirt base. then go to morph loader pro under the edit/ object menu. Add your morph to it and hit apply. if your morph is successfully applied you will find it under parameters morphs with your skirt selected. If it explodes when applied you've most likely lost your vert order somewhere in the process.

Goodluck!
