The instructions for GoZ are on pages 713-723 of the manual.  Depending on whether you want to morph the entire figure, or a single body part, you choose Figure > Export Figure Mesh to GoZ, or Object > Export Object Mesh to GoZ.

If you use that method, you'll be prompted to enter a name for the morph when you GoZ it back into Poser.

It's super easy, and super fast.

 

Yes ... Reality 3 is coming to Poser! 8-)
