Object mapped using a multi/sub-object material:

Material ID 1 for the housing of the monitor

Material ID 2 for the image on the screen

The Material modifier allows you to animate, or simply change, the assignment of material IDs on an object. If the material ID is animated, the change to a new material ID is abrupt, from one frame to the next.

Tip: If you want a gradual blend from one material to another, try animating the Mix parameter on a Blend material.

Tip: Use this modifier in conjunction with the multi/sub-object material type, to assign different materials to objects or faces at different frames of an animation, or to quickly change the material ID of an object.

Patches

As of 3ds max 4, patch objects coming up the modifier stack are not converted to a mesh by this modifier. A patch object input to the Material modifier retains its patch definition. Files that contain patch objects with the Material modifier from previous versions of the software will be converted to meshes to maintain backward compatibility.

Procedure

Example: To change the material ID of a sub-object selection:

  1. In the Top viewport, create a sphere.

  2. In the Material Editor, create a multi/sub-object material.

    Make the colors of material ID 1 and 2 different.

  3. Assign the multi/sub-object material to the sphere.

  4. On the Modify panel, choose Selection Modifiers > Mesh Select from the Modifier List.

  5. On the Mesh Select Parameters rollout, click Polygon.

  6. In the Front viewport, region-select the lower half of the sphere.

    The selected polygons turn red.

  7. While Polygon is still the active sub-object level (in the stack display, a square polygon icon appears to the right of Mesh Select), choose Surface Modifiers > Material from the Modifier List.

  8. On the Material modifier Parameters rollout, set the value of the Material ID to 1 and 2 to toggle the color on and off.

    In the shaded viewport, the lower half of the sphere changes to the color of the selected material ID.

Interface

Material ID—Sets the material ID to be assigned; this can be animated. If the input object is in face sub-selection, then the ID is only applied to selected faces; otherwise, it is applied to the entire object. The ID number refers to one of the materials in a multi/sub-object material.
