I imported a base mesh from maya, into ZBrush and have begun sculpting. Is it possible to scale that mesh on an individual axis within ZBrush? I read somewhere that it is, but I think it said it needed to be a particular type of mesh and I'm too new to distinguish ZBrush's mesh types.
Alternatively, you can use the Transpose Tools to scale across a single axis. First snap your camera to an axial view by holding shift while orbiting, then switch to Scale mode and drag out your transpose line from the point from which you want to scale, hold shift, and drag the center ring.
