ZB_18 (Part 1) | Scaling to real world size 4K

 

Hi everyone, my name is Michele. In today's Zbrush tutorial,

I am going to scale Julie into real world size using my height.

This way I can measure the length and width of the skirt to real world measurements.

Press , to open up Lightbox.

Under Tool, double click Julie to import it into the Tool Box.

It says updating additive shape layers at the top left corner here.

Zbrush is referring to this Layers tab, where we can record the progression of a

modelling process. Then dialling the intensity up or down with this slider here.

We'll come back to this at the Layers stage.

Let's just extend the edges of the canvas according to the size of the monitor.

Under Document > New Document with Autofit Window Size on,

then click on New Document.

Select Julie Tool from Tool box.

Place Julie, Click and drag on the canvas then let go. Press T to turn 2.5D to 3D editing.

Open up Subtool tab to check that the body is the active Subtool.

Or Press Shift F to turn on Polyframe to check.

I am going to use this body Subtool to resize the whole model.

Go under Zplugin > Scale Master to change the measurement unit to mm.

Under Scale Master there's a button called Set Scene Scale.

Click on it and a dialogue box will pop up with the type of units to measure in.

In my case, I am using mm. So I am clicking on this.

Then under ZPlugin,

request for the Subtool measurement of Julie's Body with this button,

Sliders to Subtool Size and with Ratio lock button on.

The numbers displayed here are the measurements of Julie's Body Subtool,

with 180mm as the Y value.

I want to change the Y value to my own height. 1560mm.

Keep Resize Subtool with All button on and click on Resize Subtool.

When the All button is on, it will resize all the other subtools.

If off, just the selected 1 body Subtool.

Once resizing is done, the model will fit to screen.

Just to be sure let's check the size under ZPlugin again.

Under Scale Master > Sliders to Subtool Size.

The Y height value is 1527mm instead of 1560mm.

Why is that? Let's fix that. Go under Geometry

and check the Subdivision levels.

Slide the Subdivision level to level to 5,

This should increase the accuracy of the mesh and increase the number of active points.

Then check the Y height value again, it should say 1560mm.

If you want to manually measure the model, you can do so by generating

a fitting box either around JUST the body or the WHOLE model.

New Subtool generates a fitting box around the selected subtool.

while New bounding Box Subtool generates a fitting box around all subtools.

which includes the height or thickness of the hair.

Let me click on New Bounding Box Subtool.

A large box will cover up the whole model.

and when I open up Subtool list, at the bottom I will see the generated bounding box.

To measure, press W to launch Gizmo and Y to change it to Transpose tool.

Snap and click at the top right point of the box,

then snap and click at the bottom right point.

The Y value will the displayed at the top left corner of the screen.

1565mm which includes the height of the hair.

Let me check that the Subdivision level is at highest level.

Ok, It is.

If I want to just measure from the tip of the head to the toes without the hair.

I can do so by selecting the Body Subtool, go under Scale Master again.

and click on New Subtool.

New Subtool will add a new bounding box around the 1 selected subtool.

In my case right now, is just the body. So the reading should be exactly 1560mm.

Let's go back to ZPlugin > Scale Master > Sliders to Subtool Size.

There it is 1559.9mm.
