Does Zbrush3 allow you to make a selection like with the mask in move mode,( Holde Ctrl+click and drag ) to hide parts of your mesh instead of masking?
That would save a little bit of time, not having to click multiple times to get the little part you want to see. Especially if your model is posed.
edit: nevermind, the option is there and how I wanted it to work.
nice!
