7. Save the Library in the MaterialLibraries folder in the Red Rocket project. Name
it rocket1.mat. (There already is a file in that folder called rocket.mat for your
reference.)
You can load the scene file Rocket_Material_Wheel_Final.max from the Scenes folder of
the Red Rocket project to skip to this point or to check your work.
Mapping the Fins: Introduction to Mapping Coordinates
An image map is two-dimensional; it has length and width but no depth. Geometry in
3ds Max, however, extends in all three axes. How is a material that contains 2D image
maps applied properly to a 3D scene object? Are the maps projected in a single direction
onto the object??™s surfaces or do they envelop the object cylindrically or spherically? The
answer depends on the type of mapping coordinates applied to the object. Mapping coordinates
define how and where image maps are projected onto an object??™s surfaces and
whether the maps are repeated across those surfaces.
Mapping coordinates can be applied to objects in several ways. The Generate Mapping
Coords option is on by default. When primitive objects are created and the Generate
Mapping Coords option is checked at the bottom of the Parameters rollout, the appropriate
mapping coordinates are created automatically.
