The Layers panel shows a neat array of effects

Giving the moon away

Now let me show you another example that uses different techniques In this exercise, you create cross sections and place more than one instance of an object in a file You also place a second 3D object in the same file You can make a present of the moon by following the steps in the following sections

Create a gift box

Follow these steps to create the first part of the package perfectly wrapped for gift-giving:

On the Web Site

Find the files you need to do this exercise on the Web site They are saved as Figure 24-23 and Figure 24-25 n

This is a PSD file of a 3D box with a lid, as shown in Figure 24.23

uncheck Intersection, set the offset to +12, and click Z-axis

You should be left with the lid of the box.

When you are reminded to save, click OK

Z-axis, and set the offset to 11.

You should be left with the bottom of the box, minus the lid.

10 Use the 3D Manipulation tools to place the bottom of the box so you can see into it.

11 Save the changes, and exit the File.

12 Rename the Figure 24-23 layer Box by right-clicking the layer and selecting Layer

Properties.

13 Use the 3D Manipulation tools to tilt the lid so it looks like it is being opened, as

you see in Figure 24.24.

14 Double-click the lid texture in the Layers panel of the Lid layer to open the texture.

15 Select File ➪ Place, browse to Figure 24-25 (downloaded from the Web site), and

click OK.

This file is a pattern created from an image of a nebula, as seen in Figure 24.25

16 Stretch the pattern to fill the texture of the box

17 Click the check mark in the Options bar to accept the placement of the pattern.

18 Save the changes to the texture, and close the texture file

The lid of the box should now have a new texture.

19 Double-click the thumbnail in the Box layer

When you are reminded to save, click OK

20 Double-click the box texture of the Box layer in the Layers panel to open the

texture.

FIGURE 24.24

You can open the box by creating cross sections of both halves

FIGURE 24.25

This image was created using the Pattern Maker, a plug-in filter available from Adobe

21 Repeat Steps 16-20 to add the texture to the main portion of the box.

22 Save this file, and close it.

You used the Cross Section tool to create and place the same 3D object in a file twice You added texture to both portions of that object Your final result should be similar to Figure 24.26 Now you are ready to create the moon

Creating the moon

To create the moon, you create a sphere in Photoshop and map an image of the moon over it

Follow these steps:

On the Web Site

Find the texture of the moon saved as Figure 24-27 n

FIGURE 24.26

The box is complete

This converts the background layer to a regular layer and gives it a descriptive name

3 Use the 3D Shape Preset in the 3D panel to create a sphere from the layer.

You see a representation of the moon, as shown in Figure 24.27

You can see my settings in Figure 24.28

10 Click OK to exit the Layer Styles dialog box.

11 Save your file.

Creating a present of the moon

Now that you’ve created two 3D object files, let’s add them to an image file to make a complete composite Follow these steps to create a composite that gives the moon away as a gift:

4 Note the areas that need to be masked, and then hide the box by clicking the eye

icon.

shown in Figure 24.30.

Tip

I created a jagged selection along the edge of the box as well as a selection around the face to take away the

sharp edge that should have been sunk slightly into the carpet.

FIGURE 24.30

Creating a selection of the areas that need to be masked

Note

You can, of course, select the areas that need to be shown rather than the areas to be masked Then there is no

need to Inverse the selection n

10 Drag the mask from the Image layer to the Box layer

11 Click the eye icon to restore the Box layer to view.

Your box should be masked into the photo.

12 Choose File ➪ Place, browse to the file of the moon, and click OK.

13 Size the moon to fit in the box, and click the check mark to accept placement.

14 Drag the Moon layer to the top of the Layers panel, placing it on top of the box.

15 Set the moon inside the box.

16 With the Moon layer highlighted, click the Rectangular Marquee Selection tool and

create a selection that includes everything in the moon layer that is above the box,

as shown in Figure 24.31

FIGURE 24.31

Create a selection to mask the moon into the box

17 Click the Mask icon in the Layers panel to create a mask from the selection

The moon is placed into the box Your finished product should look like Figure 24.32

You can see that even the most rudimentary 3D objects can become very interesting by using Photoshop tools to enhance them Just imagine what you can do with more elaborate 3D models

Summary

In this chapter, you learned some of the advanced techniques for working with 3D objects, how to use the Photoshop tools to change them, and how to add them to composite images successfully

You learned how to do the following:

l Use the 3D paint tools to paint textures directly onto a 3D object

l Use adjustment layers, layer styles, and filters on a 3D object

l Create composites using images and 3D objects
