When using GoZ to send a character to Zbrush, The mesh size is way too large in Zbrush to properly use the tools. In the Screenshot, you can see that changing the brush size slider to 1000 from the default 64, doesn't allow you a large enough brush to do much on the mesh. I believe Zbrush is made to function best on a mesh with a size around 1. Of course, setting the size in Zbrush and then sending the Mesh back to CC causes it to come in at a miniscule size.
It's as if CC exports to ZBrush expecting centimeters, while ZBrush reads it as Meters. So my character which is approximately 166 cm tall in CC, comes in to Zbrush as 166 meters tall.
You definitely need too customize your brush size but in general I've pointed out a critical issue that would resolve this by default and that is
that CC4 needs to activate Unify to scale it to Zbrush unit space to work properly with symmetry and other tools related otherwise it looses symmetry!! It should function that when the user presses GoZ again to return the model back to CC, it should scale back to CC size like the state/size before the Unify button is pressed.
