When using Projection Master it works as expected with Deformation selected but selecting the Normalisation button or the Double Sided button has no effect on the model, it gives the same results as when the Deformation only is selected, in other wards only on the surface drawn on, no side or back.
Which version of ZBrush are you using?
I’m using ZBrush 4r6.
I found the answer in the Forum, that by selecting “Double” in the Tool/ Display Properties it solves the problem
Thanks
