Last week, I got a problem with the “normal” of the model. The normal is reversed accidentally while modeling. It is because Maya does not show the angle of the normal.
This problem was solve by clicking in Maya (normal > reverse, or normal > conform)
To fix this problem is ZBrush, Display > double
This week, I’m going to reduce the polygon and doing the UV again.
Finish the ZBrush and begin texturing.
