ZB_06 | Curve stroke brush mask (Masking Part 3)

 

Hi Everyone, My name is Michele.

You're watching Part 3 of my series on masking in Zbrush.

In the last episode, we looked at how to combine 2 polygroups

into 1 polygroup using two methods. Today, we will look at

how to mask and polygroup the lip area and the mouth cavity

using Curve Stroke brush. Let's open up a new female demo

head project by pressing ",". Click on "Project" and double click

on "Female demo head".

Press "F" to center the model head. Turn off perspective by pressing "P"

so that the model is not distorted while we are editing. (Just woke up!)

As usual, let's divide it up to 800 000 so that we can be as

accurate as possible. Press "X" to turn off symmetry.

Green mask half of the head to isolate it so that we can see the

cross-section.

Turn it to the side. We can only see the front surfaces, and the back surfaces

are invisible.

Let's turn on the invisible surfaces. Go to tools. Scroll down to the bottom

of the palette. Look for "Display properties" and click on double

to turn it on. Let's analyse. Okay, we need to turn off the Subtool

for eyeballs and teeth so that we don't damage them and they

don't block our view.

From this view, we can see that we need to mask from the tip of

the nose to the bottom of the chin, to capture the whole mouth

cavity. Ctrl Shift Tab.

Ctrl Shift Lasso. Mask from the front then isolate just the front

part of the face.

Turn to the back view and hide all that is not required.

We only need to mask the lips and a mouth cavity.

At this stage, we can clearly see that it's easier to isolate the mouth cavity and polygroup it first.

Let's do that and CTRL "W" to polygroup it then unhide

everything.

Once again, isolate from the tip of the nose to the bottom of th

chin.

Hide the rest.

Holding down control. Change the stroke to FreeHand and paint in the approximate shape of the lips.

Holding down control, change the Stroke to Curve.

Press CTRL ALT and Slice away the mask area, which goes

beyond the lip area. Left to right, masks the top. Right to left,

masks the bottom

Hold down Spacebar to move the position of the starting point.

You can also use this to change the direction of the curved line.

You can bend this curved mask line by pressing ALT once.

Press ALT 2X for a sharp angle.

If you need to change the direction, just press Spacebar and

then move it to change the direction.

Once done, rotate to the back and check the extent of

masking. Add more mask where needed before pressing

CTRL or CMD W to polygroup it and that's it.

These are all the basics of masking you need to get started.

In the next episode, I'll be showing you how to use this

Transpose Smart Masking to isolate the tongue from the teeth

Subtool into a different polygroup.
