Here is the method I use to make morphs in Blender.

Zero the figure

Select the head

File - Export obj file - select only the head in the hierarcy. Export with all options off - no boxes ticked.

Import the obj file into your modeller, doing whatever you need to do to keep the vertex order unchanged (I don't know Wings, someone else may have more knowledge).

Make your changes until you are happy with the shape. Do not delete or add any vertices - only move them. In Blender I use sculpt mode to do this.

Export from Wings as an obj file, again making sure you keep the vertex order unchanged (This is extremely important. If you mess up the vertex order the head will explode when you apply the morph). There must also not be any translation or scaling changes.

In Poser, load the figure again and select the head. In the object menu, select "Load morph target". Browse to the object file you saved from Wings and select it. If you get an error message here, you have changed the number of vertices and it won't work. If you get no error message, the export from your modelling program was correct. A new dial will appear in the head actor, dial in your new morph.

Good luck - this is tricky at first, but it is fun.
