To use multiple UVW channels in the same object: Note: If a UVW Map modifier is applied to multiple objects, the UVW Map gizmo is defined by the selection, and the mapping that results is applied to all the objects.

Apply mapping coordinates to an object with no mapping coordinates, an imported mesh, for example.

Objects with built-in mapping coordinates lack a gizmo.

Transform the mapping gizmo to adjust map placement.

Apply one of the seven types of mapping coordinates to an object.

A diffuse map on map channel 1 and a bump map on map channel 2 can have different mapping coordinates and can be controlled separately by using two UVW Map modifiers in the modifier stack Apply one of the seven types of mapping coordinates to an object on a specified map channel.

The Generate Mapping Coordinates option, available during the creation of primitives, uses map channel 1 by default. If you apply a UVW Map modifier to an object with built-in mapping coordinates, the applied coordinates take precedence if map channel 1 in the UVW Map modifier is used. Note: Drawings that are imported or linked from Autodesk Architectural Desktop and Autodesk Revit do retain the mapping coordinates that were assigned to objects by those products.
