Mouth and eyes

ZBrush Usage Questions
#1

I was wondering if someone could tell me or perhaps re-direct me to a tutorial that involves engraving holes for mouths and eyes. I see a lot of people just doing closed mouths so I assume they just sculpted on top, however I’m trying to make a few models that include some poses with mouths closed and open and I still want the interior of the mouth so like teeth and tongue. Heres an example of how I’ve done the mouth on a model…I just pulled and dug however it killed the typology (I think?). I’m still new to ZBrush and to prevent myself from seeming more stupid than I already have, I’ll just end with a smile!

:smiley:

Thanks in advance aswell. <3

The way you are going about it this is fine. Deforming the mesh to the degree you are is going to cause some topology problems based off of your base mesh. These are small problems than can usually be fixed by simply stepping up in subD levels.

The catch is if you want even poly distribution within the mouth then you’ll have to retopo or create a new unified skin that will give you even flow throughout your mesh.

If the mesh is only going to be static and not animated then having some bad geo inside the mouth isn’t really a problem as they can be hidden with the teeth and tongue.

yes the problem is the topology, another way that avoids the problem is to make with a few clicks right on the beginning a good topology :

  1. select on the mesh a rectangular area of polygons where about the mouth will be and hide the rest of the mesh.
  2. be sure you are on first subd level, then hit in geometry pallette “edgeloop”. this creates an edgeloop inside the rectangular area.
  3. use the move tool to pull and push this new loop into an oval open mouth shape, think of it as lips of open mouth seen from front.
  4. select the polygons of the oval mouth shape and hide the rest.
  5. make another edge loop. and repeat 3 and 4 if you feel is needed.
  6. now push as you did on your mesh, the inside of the newly created oval shapes inside to create the hole of the mouth opening.

you will now have nice clean borders, since the mesh is supported by an edgeloop there, the first edgeloop is about where the lips will be, the others provide a clean geometry inside the open mouth.
