Join Ryan Kittleson for an in-depth discussion in this video Understanding surface normal direction, part of ZBrush 4 Essential Training.
Occasionally, you may find that models that you import from other programs will…appear to be inside out.…This is because polygons have two sides: a front and a back.…The direction that the front side faces is called the normal, which is…a mathematical term.…It doesn't mean what the word 'normal' normally means in this context.…Sometimes ZBrush will get confused about which side is which.…Since the back side of a polygon is invisible by default, the model can seem to be inside out.…This problem is easily corrected.…
Let's open up the DemoSoldier and expand the Display Properties sub-palette.…Right now, there's no problem with the normals.…But if we click the Flip button, the active subtool looks like it's backwards.…You see now we're seeing the inside of the model.…This is because ZBrush has just flipped which side of the polygons are front…and which are back.…Clicking Flip again will set the Normals in the correct direction.…
Let's hit Flip once again in order to see what Double does.…Double makes both sides of the model visible instead of just the front-facing side.…
