4 Mapping artwork to 3D surfaces and lighting.
In order to map a saved symbol onto a
selected extruded object, he re-entered the Extrude and Bevel Options dialog and
clicked the Map Art button. Since the key blade originally consisted of two joined
pieces, the map dialog treated each half of this top plane as a separate surface. This
enabled him to map the right half of the blade with the metal symbol and the left half
with a gradient symbol, creating the dark ridge down the center to give the illusion of
a worn step on the blade's left side. McGarry then entered More Options in the Ex-
trude and Bevel dialog and adjusted lighting for each part by moving the highlight on
the sphere and reducing Ambient Light to darken the side shading. Lastly, to en-
hance the 3D illusion he manually added shadow effects (Effects> Stylize> Drop
Shadow), and then drew paths to which he applied Effect> Blur> Gaussian Blur for
the blade and key ring shadows.
