To make one of the sub-materials a solid color: ■ On the Multi/Sub-Object Basic Parameters rollout, click the color swatch next to the sub-material button. In the Color Selector on page 391, choose a color. The color swatches for sub-materials are shortcuts. They assign the color you choose to the sub-material's Diffuse component. To assign one of the sub-materials to a sub-object selection: 1 Select the object, and assign a Multi/Sub-Object material to it. 2 On the Modify panel on page 7633, apply Mesh Select on page 1527 to the object. 3 Click Sub-Object and choose Face as the sub-object category. 4 Select the faces to which you will assign a sub-material. 5 Apply a Material modifier on page 1517, and set the material ID value to the number of the sub-material you want to assign. The viewport updates to show the sub-material assigned to the selected faces. The material ID values in the Multi/Sub-Object material and the material ID numbers in the Select Face rollout correspond. If you set the ID to a number that doesn't correspond to a material contained in the Multi/Sub-Object material, the faces render as black. WARNING Some geometric primitives do not use 1 as the default material ID, and some, such as hedra or box, have multiple material IDs by default. TIP You can also use the Edit Mesh modifier on page 1353 to assign a contained material to selected faces. Apply Edit Mesh to the object, go to the Face sub-object level, and select the faces to assign. Then on the Edit Surface rollout, set the material ID value to the ID of the sub-material. (You can drag and drop on page 5312 a Multi/Sub-Object material to an Edit Mesh modifier as you can to an editable mesh object.) To add a new sub-material: ■ Click Add. Compound Materials | 5723
