is rendered.
4. Go to the Material Editor. Click the Go to Parent button to get to the Maps rollout for
the parent material. Click on the bar next to Opacity and select Bitmap from the
Material/Map browser. In the Explore window, navigate to the Texture Scene Files
folder on the CD and select Chain Link OP.tif (shown here).
5. The tiling values for the opacity map must be the same as the diffuse map; otherwise,
the transparency of the fence will not line up with the links of the fence. Go to the
Coordinates rollout, and change both the U and V Tiling to 3.0. Render to see the
results shown in Figure 7.60.
You can see immediately how useful opacity mapping can be. 3ds Max uses the white
portions of the image map to display full opacity, whereas the black areas become transparent.
If you did not have an opacity file such as the one in this exercise, you could easily
create one by painting a black-and-white matte of the color image that you are using for
the material.

In a previous exercise, you turned a boring sphere into an exciting pool ball using Diffuse
and Reflection maps.
