The XRef material lets you use in your scene a material applied to an object in another scene file. As with XRef objects, the material resides in a separate source file. You can set the material properties only in the source file. When you change them in the source file and then save it, the material's appearance can change in the master file that contains the XRef.
The Show Map In Viewport button works for an XRef material only if the same button is turned on in the source file. Otherwise, it is disabled.
Click to open the XRef Objects dialog that highlights the source file's current record with its object displayed in the XRef Entities list. If no file and object have yet been selected for the material, the XRef Objects dialog is displayed, and lets you browse for the file and material to use.

Displays the name of the source object followed by the material name in parentheses. For example, “Shaker ( Chrome ).”
Click to display the XRef Merge dialog pointing to the scene in the XRef File Name field. Here, you can specify a different object whose material you want to reference.
Displays the status of the material. For example, if the file and object are both found, this field says “Status: XRef Resolved.”
