In the next section, we will use a modifier to change the mapping coordinates on the
Top Fin object.
COORDINATES ROLLOUT EXPLANATION
The Coordinates rollout in the Bitmap parameters for a 2D image has several options, as you
can see in Figure 7.82. Here is a brief explanation of the settings:
Applies the Map as a Texture Map or Environment You can select the type of coordinates
from the Mapping pull-down menu. As you can see in Figure 7.82, there are different
coordinate choices for Textures or Environments.
Offset UV Changes the position of the map over the surface of the geometry. U moves
the bitmap horizontally, and V moves the bitmap vertically on the surface.
Tiling UV Determines the number of times the map is repeated along each axis.
Angle UVW Rotates the map about the U-, V-, or W-axis in degrees.

Using a UVW Modifier
Instead of dealing with the surface??™s own mapping coordinates as we have tried here, we
are going to use a modifier to replace those coordinates on the geometry. The UVW Map
modifier makes the decal act more like a real decal that we can control by moving a modifier
gizmo around to place the coordinates as we please.
