I don’t use goZ, and struggle to understand what makes it usefull.
In zbrush, make your morph. Load it in studio with morph loader. Adjust rig to shape and erc freeze if needed.
Back in zBrush, with your morphed mesh, click autogroup. Shift click figure. Delete hidden.
Click auto group with uv’s
Merge groups so that you have your limb group, your face group and a torso group with ears.
Subdivide until you have a few million polygons.
Sculpt in your displacement details and polypaint your texture maps.
Make sure you’ve got the uv border set to 12 or higher
At the highest subdivision level, shift click the face, create texture from polypainting, clone, flip, and export. Turn that texture off and repeat with limbs and torso.
At your lowest sub division level, do the same with displacement maps.
Use maps in studio.
