How to make a inner cavity to a head sculpt?

ZBrush Usage Questions
#1

Hello,

I have head that I sculpted in zbrush with a lot of detail and layers on it.
How would I go about making a thin inner cavity to this model, and still preserve the outer details and layers?

After I am going export this as a STL file to be made into a real model.

Thanks,

A pic of what you want to do would be helpful…I’m a little fuzzy. But it sounds like what you may be looking for is backface masking. It allows you to sculpt on one side of a thin mesh, without disturbing the opposing side.

Backface Masking can be turned on for any brush via the brush menu >Auto masking> Backface Masking.

Thanks,

I,m also wanting to know if zbrush can make a thin inner cavity/lining for this head?
Btw, it has an opening at the neck area.

Again, I have very little idea what it is you want to do from the vague description, but Zbrush can create “skins” with thickness to them either via the Extract control in the subtool menu, or by importing the topology into topology-editing mode, and making an adaptive skin with a thickness value assigned to it.

Perhaps one of those would be helpful for what you want to do. Failing that, I really need a clearer explanation of what you want to do. I mean, you can make a “cavity” just by sculpting with Zsub.

Try masking the entire mesh and ‘Extracting’ with a negative value entered into the thickness slider. ~S.~

I will post an image later when I get home.
Snark, I will also give that a try later on.

Thanks,
