4. The Material/Map Browser opens again, but this time it displays maps. Choose Bitmap from the extensive list and click OK. The Select Bitmap Image File dialog box opens automatically in this standard file browser. Select WomanStanding.tif and click Open. The Material Editor's rollouts change to those of the bitmap. Click the Go To Parent button to return to the top of the material hierarchy.

Now that you have the diffuse color map, the next task is to copy it to create an opacity map. The opacity map determines the boundaries of the object and gets its data from the image's alpha channel.

5. Drag the M icon (meaning mapped) from the Diffuse Color channel to the Opacity channel, as shown in Figure 4.41. The Copy (Instance) Map dialog box opens. Click the Copy radio button and then click OK. Because the Opacity map must take data from the image's alpha channel, it is necessarily different from the diffuse map, so a unique copy is needed.
