Modeling

The tutorials in this chapter will introduce you to

modeling in 3ds Max.

• Converting splines into geometry using

modifiers

•S ingupvewpo swthb ckgroundima s

• Editing a model at sub-object levels

•F tu sinEdabePoy

• Using Merge and Xrefs to bring external objects

in your scene

Modeling in 3D can be likened to sculpting.

Many different techniques can be used to create

the objects in your scene. The techniques you

learn are adaptable to any style of modeling you

need to perform. For instance, if you’re building

models that will be incorporated into a game,

you’ll be most interested in low polygon modeling

techniques. The same techniques will be equally

beneficial when building highly detailed models

forarchitecturalpresentationsormotionpictures.

Files for This Section

All the files necessary for this tutorial are provided

on the program disc in the \tutorialsdirectory.

Before starting the tutorials, copy the \tutorials

folder from the disc to your local program

installation.

The tutorials in this section are geared for the

beginning-to intermediate-level modeler. Each

tutorial takes from 30 minutes to several hours to

complete.

Beyond modeling techniques, the tutorials also

expose you to the Material Editor and show you

how to apply materials to objects in your scene.

That familiarity will help when you dive into the

materialsandmappingtutorials(page555).

Modeling a Space Scene

In this tutorial, you will create a planet and its

moons, and an asteroid.

Features Covered in this Tutorial

•C ingp im eob s

• Using a modifier to alter an object’s shape.

• Creating and editing spline objects

Chapter 2: Modeling

Modeling the Planets

In this lesson, you will create the planet Mars and

itsmoons.Youwillalsomakechangestothe

objects in the Create panel.

If at any point the object parameters disappear,

choose the Select Object tool from the main

toolbar and reselect the object. Then open the

Modify panel and make your changes there.

Create the planet:

1. Choose File > Reset. Click Yes in the dialog to

reset.

2. OpentheCreatepanel.Makesurethe

Geometry button is on, and click Sphere in the

Object Type rollout.

3. InthecenterofthePerspectiveviewport,drag

to create a sphere of any size.

4. In the Name And Color rollout, change the

name of the object from Sphere01 to Mars.

Skill Level: Beginner

Time to complete: 45 minutes

Features Covered in This Tutorial

•C ingp im eob s

• Moving objects in the scene

• Using a modifier to alter an object’s shape

5. In the Parameters rollout, change the Radius to

100 and set the Segments to 64.

Tutorial Files

All the files necessary for this tutorial

are provided on the program disc in the

\tutorials\intro_to_modelingdirectory. Before

starting the tutorials, copy the \tutorialsfolder

from the disc to your local program installation.

Increasing the number of segments makes

the planet look smoother. This is especially

important for close-up shots, where every detail

is revealed.

Modeling the Planets

4. Hold down Shift on the keyboard and drag

the gizmo’s X axis to the left and then release

the mouse button.

Click Zoom Extents Selected from the

Zoom Extents flyout.

The sphere moves back and to the center of the

viewport.

Note: The grid is no longer visible because the

size of the grid is fixed and is too small to be

displayed after the zoom was performed.

Create the moons:

MarshastwomoonsnamedDeimosandPhobos.

Instead of making additional spheres, you can

create the objects by cloning.

1. Right-click in the Top viewport and click

Zoom. Place the zoom cursor on the X axis,

just to the right of the sphere.

2. Drag downward to zoom out. Stop when Mars

looks half its previous size.

5. In the Clone Options dialog, leave Copy

selected and change the name of the new object

fromMars01 to Deimos.ClickOK.

Tip: If necessary, click Pan to move the

scene so that you can see Mars in its entirety.

6. Open the Modify panel and change the

Radius parameter of Deimosto 22. Since this

object is smaller than Mars, reduce its segments

to 24.

7. Shift-clone the second moon from the Deimos

moon using the same process, only this time

position the clone closer to Mars. When the

Click Select and Move from the toolbar.

The Transform gizmo appears in the viewport.

Note: If the transform gizmo doe s not appear,

press the keyboard shortcut, X ,tomakeit

appear.
