Texturing Extruded Objects Doesn't Work

Sometimes you apply a texture to an extruded object and it still won’t render. What’s wrong?

Here is a typical example. You’ve made an object and you made the correct texture, but still the texture is not showing up.

You can see on the Object Info Palette that I have applied the texture correctly, but if you look at the Attributes Palette you can see that the object has no fill. This means that it will stay wireframe.

Look at this example. I have changed the Attributes Palette so that the object has a solid fill. Everything else has remained the same.

Now the object is displaying the correct texture.
