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.

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.
