I shocked my pen a while ago by dropping it on the floor (tip #1, don’t keep your pen in that springy stand it comes with. )
Anyway, the front part of my pen doesn’t work anymore, only the back of the eraser part. So I stopped using it until it has winked from the table at me just now, so I finally drop my clunky mouse and experiment.
Things are a bit different when painting with the eraser end.
As well, a note to Pix or Aurick, the Blur brush is the Sharpen brush and the reverse is also complimentary.
But if you’ve ever wanted a quick change of the editing tools on the fly (those positive, negative modifiers), just flip your pen and it’s instantly in reverse mode.
Painting tools seem to work on the zsub mode, though dropping 3d spheres and such will cause them to pop back up.
But it seems I won’t be Zbrushing for at least a month - my pen will take a trip to the Wacom factory soon, meanwhile I wish there was a way to reverse or turn off eraser mode to just regular mode (perhaps in the Tablet palette) for both ends.
I don’t know if it’s just my lack of use, but painting with the eraser mode seems more comfortable.
