I think harie does what I do- Export the body part from Poser in OBJ

• Convert to COB in 3D Explorer
• I scale up by 20 rotate X 90 and Z 180
• Open the COB in Truespace
• Dont move the whole, just the vertices you want to morph.
• Save in COB
• Convert back to OBJ in 3DExplorer this time scaling by 0.05 and doing the rotate.
• Back into Poser and load the morph.
