ZB_04 | 1 Ctrl button with 5 ways of masking (Masking Part 1)

 

Hi, Everyone my name is Michele. In today's Zbrush tutorial, I'm

going to show you 5 shortcuts to apply your mask. First, let's

open up a New document, if you need to. Under Document and

then New document

with the W Size turned on to fill up your whole screen with the

canvas space. If you have just launched your Zbrush, you can

go ahead and press ","  to turn off your Lightbox .

Then, let's go to tool and Sphere3d. Click and drag in the middle

of the canvas.

Press "T" to switch it from 2.5D default canvas into 3D canvas.

Then click on make Polymesh3D to activate the polygons.

Before showing the first method, I am going to show you

how to activate your mask pen. Just press CTRL key and it will

switch the default standard brush into mask pen. The stroke

I'm using freehand stroke which is equivalent to painting.

You can select others but for Method no. 1, I will use this.

Alpha. Currently I have none on but I'm going to use one of my

own custom alpha, I have just made.

If you want to know how to make a good 2D Alpha, head on

to my previous video linked above.

Okay, now let's begin with Method no. 1. This is the

simplest method which is to paint over your model like a paint

brush. Holding down control. Cover whichever area you want to

protect. like a band-aid. Leaving behind the

other parts of the model to edit.

If you're using alpha, it will be used as a brush pattern.

If you don't want any pattern, go back to Alpha

and click Alpha off .

You can go ahead and paint it with the regular round brush.

The brush size is adjustable with this slider 

or with the "S" key and a slider will pop up for you to adjust.

Next method is pressing CTRL,

and instead of brushing on a model, I'm

going to switch to my own Alpha 2.

Click outside and drag. You will see the pattern greyed out

on the model. However, as you can see, the mask is very

pixelated because it has only 8 000 active points.

In order to make a seamless

smooth edge, we need to divide it up to 2 million points.

Go to Geometry.

Divide it up to 2 million by clicking this button or pressing

CTRL D, a few times.

I'm going to press CTRL,

Click on the outside of the model.

Drag downwards and press Spacebar to adjust the position.

Let go of all the buttons.

Let's turn on Polyframe by pressing Shift F

or pressing this button. Then press Command/ CTRL W

to isolate it into its own Polygroup.

Now you can extrude it using the two methods I showed in the 

previous video linked above.

The 3rd Method is pressing Ctrl,

Click outside the model, 

similar to the second method, you need to begin

outside the model.

Then, instead of letting go of all the buttons,

let go of just the CTRL button.

When you let go of the CTRL button that means you want to

ignore the brush alpha. You just want a sharp edged,

rectangular alpha.

This means you have masked this area in the middle and

you can edit the model outside this mask area.

The 4th method is very similar to the 3rd.

Press CTRL, starting outside the model, on the background.

Let go of control and re-press ctrl button again.

Let's try it out.

Press CTRL, Click background and drag.

Spacebar to reposition.

Release CTRL and repress CTRL again.

Your mask will turn green which means it has been inverted.

Let go of your left click on your pen. Holding down CTRL key and

this is what you will get. Isolated and editable pattern from your alpha.

Now I can inflate it and move it as i like without affecting the

parts which have been hidden.

Now let me undo this and move on to Method no.5 . 

Ctrl,

begin outside the model.

Click and drag.

Spacebar to position.

Release control,

Repress control and Release control again.

This will give you a green mask which means an inverted mask.

It will ignore your alpha brush, giving you a sharp edged mask

just like Method no. 3 and those are the 5 methods of masking just

by pressing CTRL.

In the next video, I'm going to show you how to apply these

5 Methods of masking on a Demo head.
