What’s up im currently using ZBrush 4 r4, i’m quite familiar with ZBrush 4 r2 with the general aspects, but the problem here in the r4 is that i couldn’t find the option to delete hidden masked geometry, usually this option is in the geometry submenu, so could anyone help me with this dumb but necessary answer.
Tool > Geometry > Modify Topology.
It’s right under the MicroMesh button.
