...or if you want to make your own morph that works with v4, you can try Colorcurvature's python program 'PoserMorphLoader'.

It's not a free program, though.

In my case, I use Hexagon and PML to make morph to correct joint bending.

Great thing about PML is that you can export posed obj and directly work on it in Hex, then back into poser, and apply morph automatically.
