way would appear in 3ds Max assigned to the linked AutoCAD Architecture objects. However, this practice is not recommended because the native 3ds Max Architectural materials have more complete information on the surface characteristics of objects, and are easier to create and share. In other words, you work faster, share easier, and get better results using native 3ds Max rendering materials in both AutoCAD Architecture and 3ds Max. See also: ■ Material Editor, Materials, and Maps on page 5259 UVW Mapping in AutoCAD Architecture Objects An important consideration in how many materials render is how they are "mapped" to the surfaces of the objects they are assigned to. This is especially important for materials that use bitmaps on page 7926 to define the diffuse color of a material, or the bump and cutout special effects. As an example, you may have scanned a picture of wood grain for use in a material, but when the material is applied to an object, how large should the image of the wood grain be? Which way do you want the grain to run, and how do you want the grain to wrap around the corners of a three-dimensional object? How two-dimensional maps are applied to three-dimensional surfaces is represented by mapping coordinates on page 8034, which are stored as UVW coordinates on page 8161. In cases where mapping coordinates are likely to be important to the rendered appearance of an object, AutoCAD Architecture (formerly Architectural Desktop) assigns UVW coordinates to object components. 3ds Max translates these coordinates and stores them in the object mesh that is displayed and rendered in the 3ds Max scene. You can adjust these coordinates in 3ds Max using the UVW Xform modifier on page 1955, or you can redefine them all at once using the UVW Map modifier on page 1931. IMPORTANT Make sure that Rescale is turned on in the Attach Panel of the File Link Manager dialog. Otherwise, if the units do not match, the UVW coordinates will be incorrectly scaled when linked to 3ds Max.
