ZB_16 | 4 ways to delete Curve lines (4K)

 


I just found out while doing a new Zbrush tutorial,

that the shortcut to deleting a curve line and a strap

is to press Alt while drawing another curve line over the unwanted strap.

In order to remove the curve line only, tap anywhere on the masked model, that's it!

Of course there's still the longer route of using Zmodeler brush

or Curve options under Stroke menu.

ZB_15 | Adjusting belt depth and applying depth on IMM brush using Curve brush depth ( 4K )


Hi Everyone, my name is Michele.

In today's episode I'm going straight into curve depth brush

option under brush menu. At the end of the tutorial what I'm

trying to achieve is this result, where the belt is sitting

on top of the skin and totally not embedded

I think this is suitable not only for belt models

but for 3D printed items that you can

wear like armour or mask

Let's start.

Over here I have Julie's torso as a polymesh3D.

CTRL right click, Move right to zoom in.

Hide 3 strips of left/right polyloop with the bottom strip as a

frame for a curved line.

Ctrl Shift tap on an edge for each polyloop.

Then, Ctrl Shift tap on a polygon to invert the visibility.

This way we can look from the top or

bottom to check on the thickness and

depth of the belt later on.

In order to view the inner surface, let's

turn on Double, from Display properties.

Now using Curve Strap Snap, Click from

the center of the visible strips, Drag

towards the bottom edge. When the cursor

is at the edge of the strip. Press and

hold Shift. When a Curve line appears,

you can let go of your stylus and Shift.

a strap will appear in place of the

curve line. Please check out my previous

tutorial on how to use an edit curv

strap snap. When I let go of the stylus,

the torso will also be masked. This way I will not

be able to edit the torso accidentally.

From this view, we can see that the belt

is quite thick and it

is embedded into the skin as well as

extrude out of the surface of the skin.

I want the back edge of the belt to butt

against the skin surface as close as

possible.

In order to achieve that, go

on the brush then Depth tab.

There is an image with a black dot and a white circle with a line

running across the center.

The top of the circle is the highest point of the strap.

The bottom of the circle the lowest point.

The black dot the center position.

The black line the surface of the skin. To demonstrate the

effects of this black dot and white circle.

Let me increase the thickness of the

belt which means the Z intensity to 50.

Lightly tap on the belt. Lightly, so that I don't accidentally

move it.

Now the thickness is equally distributed

inside and outside of the skin surface.

Let's use the depth tab to pull the belt out of the skin. Sounds

dramatic.

Increase the imbed by clicking and dragging upwards on the

white circle or black dot.

[Music]

Once again lightly tap on a red curved

line to update the strap.

See how it is raised above the skin surface just like the image

on the Depth tab.

If you rotate the model around, you can see the belt is floating

on top of the skin because the imbed is at the maximum;

100 points.

Let's lower the depth so that it is closer to the skin surface,

about 70 points.

Basically, you can keep adjusting the depth by raising or

lowering the imbed value to the desired depth.

Let me just speed up this whole adjustment process where I

eventually ended up with embed value of 90 points.

Another thing to note is that curved line remains editable until

you use another brush or action

to modify your model.

For example I use the select lasso brush to hide another strip

then go back to click on the curved line, curve strap snap will

generate another new strap on top of the existing strap.

The previous belt is merged as part of

the torso sub tool with a different polygroup color.

So, overall there is only one subtool but

three different polygroup colors.

Let me Ctrl Z to undo all this. Another

way to keep them separate is to split

them out as separate subtools

so that I can turn them on or off

when I'm not sure which look I'm going for. Go under Subtool,

Split and Split unmasked or Split masked.

The only difference I found with these two are; whichever

option you clicked on, for example I clicked on unmasked

points. That polygroup Subtool will be below the original

Subtool.

If you have transparency turned on like I do,

whichever Subtool is not active will be see-through.

This way we can analyze the effects of different versions of belt better.

[Music]

Even though I'm using Brush Depth on

Curve line in this tutorial. Brush depth

also applies for other brushes without curved lines such as

Insert Multi Mesh.

B > I and you can select from

the different brushes available.

The only difference is that there is no

red line to tap for updates.

but needs to be redrawn in order to

reflect the changes.

Let me draw an eyelet as an example. The

brush depth is at zero.

I need to remove subdivision levels to

be able to use IMM brush.

Click and Drag down to apply on a

surface.

Let's view from the side.

[Music]

Let's lower the depth by changing

the imbed value to 38,

and then press Ctrl Z to undo,

and redraw the eyelet again with the new

imbed value.

If you want you can still change it into

a Curve line by going under Stroke then

Curve,

to turn on curve mode.

This way we can update it by tapping on

a curve line

like what we have done previously.

This is still a curved line with an

imbed value of -38. Let's change

it to negative 18.

Then lightly tap on the curved line

again to update.

[Music]

There are still many more brushes which

will respond to this Brush Depth option.

Just go to B > I,

select any IMM brushes to explore. There

are at least 20 of them here.

It definitely did

take me some time to explore,

but just remember that if it is not a

Curve line it needs to be redrawn to

reflect the updates,

and with that let me just end my

tutorial here and enjoy exploring.

in the next tutorial

I'm going to use the belt I made to

extrude out a plane so that i can have

some fun with dynamics.

If all is well, I'll see you in the next

tutorial.

Stay away from omicron.

[Music]

ZB_14 | How to form a belt with Curve strap snap without Frame mesh with subtitles (4k)


Hi Everyone, my name is Michele.

In tutorial 12, I ended by showing how to form a belt with Frame mesh and Curve strap snap.

In this video, I am going to show you how to do the same thing without Frame mesh.

It is faster but sometimes a bit tricky to control. Let's start.

Launch Zbrush and close the Homepage pop up.

Wait for Lightbox to load.

Click on Tool in Lightbox and double click on Julie.

Press , to Close lightbox.

Place Julie on canvas . Click and drag down.

With Julie's torso selected, Press on Make Polymesh3D.

Hmm...I should expand the canvas size. Let's create a New Document.

Document > New Document > with Autofit on.

Click and Drag down on the background.

Shift F to turn on Polyframe. Hmm..I forgot to press Edit. Never mind let's start again.

It's in 2.5 D that's why I can't turn on Polyframe. So I need to clear the canvas. Ctrl / Cmd N.

Click and Drag down on the canvas again and Press T to edit.

then click on Make Polymesh3D.

Let's use ONLY Curve Strap Snap to create a quick curve line around the waist.

Zoom in. Ctrl Right Click move right.

Just to be clear, this torso is made up of many different polygroups.

Let me isolate them individually . Cmd or Ctrl Shift Tap.

the legs, arms and body to check that they are all in separate polygroups.

The body is divided into front polygroup and back polygroup.

So there are 2 polygroups and 1 polygroup intersection within the torso alone.

Let's grab Curve Strap Snap. B>C> Click on Curve Strap Snap.

Change the draw size of the brush on the background, Press S. Slide to 10.

Click on where you want the starting point to be and drag to the right or left.

Once I have moved the cursor past the torso. Press Shift to loop the curve line around the waist.

Adjust the angle by moving your cursor up or down.

When I'm happy with the placement of the curve line, I release my stylus.

Tap on the curve line and drag it up or down to reposition.

Tapping on the Strap will also make the strap conform well to the surface of the waist.

When you click and drag out the curve line, don't stop at any polygroup

borders or intersections then press shift or else this will happen.

The strap will align to the intersection and snap to it.

It will snap to the edges instead of looping around the waist.

Remember to drag the cursor past any edges or borders, then press shift.

Then just lightly tap on the curve line for it to match the shape of the waist.

Let me undo that and try it on the wrist.

Same thing on the wrist. If there's only 1 polygroup it is easier to ring around the model.

On the neck. with 2 Polygroups.

Let me start at the intersection of these two polygroups and see what happens.

I always try to pull it towards the angle I want the ring to appear.

It works as long as I have dragged past the borders or edge of the polygroups.

Then I can lightly tap on it to conform it to the contours of the neck. Drag it down slightly.

Let me Ctrl Z to undo.

Let me test out ending my cursor on the edge of the polygroups.

See how it snaps to the edges?

Let's try again.

Same thing, its snaps to the intersection.

When I dragged the curve line pass the borders, away from the model and press shift,

The curve line snaps around the neck.

Then I just have to lightly tap on it to match it to the contours of the neck.

Now that we are done with the details of how to use that quick trick,

In the next video, I'll explore more about Curve options, if I'm not distracted with other tricks.

I'll be exploring Depth tab in Brush menu.

ZB_13 | How to form a belt with Frame mesh & Curve strap snap with subtitles (4K)

Hi Everyone, my name is Michele.

In the previous video, I imported 2 skirt images on Z plane under Draw menu.

In this video, I am going to form a belt using Frame mesh & Curve Strap Snap.

Let's get started!

Shift F to turn on Polyframe.

Ctrl, Right click , move right to Zoom in.

Isolate a polyloop as base for the belt.

Press Ctrl/Cmd Shift to use Select Lasso brush with Lasso stroke.

Hover over the vertical edge of a polygon. If it says "Edge", Ctrl/Cmd Shift tap on it.

This will hide a strip of polyloop that goes all the way around the waist.

Actually, there are two types of "Edge"s you can tap on.

Left/Right Edge hides a horizontal strip.

Top/Botttom edge hides a vertical strip.

So watch out for the type of strip you want to hide. In this case, a Left/Right Edge.

So I have hidden a polyloop to use as a base for the belt.

Let me Ctrl W to regroup these into another colour.

Then Ctrl Shift Tap on a “Poly” to invert the visibility.

If I tap on "Edge" instead, another strip is hidden.

Tapping on "Poly" or "Point" will invert the visibility.

Let's check if the polyloop goes all the way around the waist.

This will be the base to create a frame for the belt.

Go under Stroke menu, Dock it.

Under Curve Functions, there are 3 options. Border, Polygroups and Creased edges.

Polygroups option is for creating a frame between two intersecting polygroups.

In my case, there are no intersecting polygons. So when I click on Frame mesh. Nothing happens.

but when I turn on Border, turn off Polygroups and click Frame mesh.

Curve functions will frame all borders with a Curve line.

Let me Ctrl Z to undo Frame Mesh and unhide all polygons. CTRL SHIFT Tap background.

Let's try out Polygroups. Border off, Polygroups on. Click on Frame Mesh.

Curve functions will form a curve at the intersections of 2 polygroup colours.

Let me undo Frame mesh and isolate this polyloop. Ctrl Z and Ctrl Shift Tap Polygroup.

Border on, Polygroups off. Frame mesh.

Now that I have 2 curves available. I can pick one to put a belt on.

Let's test it out.

B>C>9, Brush > Curve > Strapsnap

Click on the curve line with the selected brush.

Just like that we can have a fitting belt on the waist.

Should I keep the higher or lower belt?

I think I'll use the lower curve line.

Let's use Zmodeler brush to delete the top curve line. B>Z>M.

Hover over the top curve line.

When the word Delete appears, press spacebar to see the actions available.

Do I want to Bevel or Delete? Delete. Do I want All curves or just a curve. Just a curve.

Then click on the curve I want to delete and that's it.

Let’s go back to Brush > Curve > Strap snap .

Click on the curve line,

and check the placement.

What about the width and thickness of the belt? Let's change the brush size under Draw menu.

Draw size affects the width.

Z intensity affects the thickness.

I can also use Spacebar as a shortcut to change the draw size & Z intensity.

Let's try draw size 200, then click on the curve line.

Let me quickly adjust it to a desired thickness and width.

Sometimes I accidentally moved it when I click on it, so just undo and reclick on the curve line.

If it's embedded into the waist, try to thicken the belt using Z intensity.

There's another way to raise it above the waist.

In the next tutorial, I will use Curve tab under Brush menu to do this.

to lift the belt above the curve line so that it's not sunken.
