Hi Rain Belt
I recommend watching the introduction videos on Zbrushclassroom (Masking)

I personally believe there is no ‘correct way’ to do a task in Zbrush. There are many ways to complete what you are trying to accomplish.
I can only guess, but I believe you are masking the area, but are not inverting it, so you can sculpt on the unmasked area.
To explain what I mean in regards to the correct way. What you are trying to accomplish can be done in many ways, for example:
- mask where you want the eyelid, invert and then sculpt (claybuild up or inflat) the eyelid
- mask where you want the eye lid, invert and use the transpose move to extract the eyelid area
- If your polygons are low, you could create a polygroup for the eyelid area and then qmesh it out or extrude and then sculpt.
- Or you could wing it, and just inflat brush/clay buildup the eyelid area without masking
- You could dig into the eye socket area and then build up the eyelid area.
- Create a seperate tube for the eyelid area, mold it into position and then merge it with other subtool (must be in dynamesh)
Hope that explains by multiple methods
SupremeFunk on youtube does some great timelapse vids. If you can slow them down, it might give you some ideas.
