I am new to zbrush. I want to put an alpha mask on polymesh, but every time when I select the drag and drop brush and an alpha and hold the CONTROL KEY it reverts back to a freehand brush and mask pen brush - I have followed the tutorial - I can’t figure out what I am doing wrong
While holding down Ctrl, select the DragRect stroke and then your Alpha then draw it on the mesh. You have to hold down Ctrl for the whole operation.
Also, see my post here.
