The Materials tab allows you to replace the standard Revit materials with more powerful and versatile V-Ray materials, including .vrscan files. This includes the ability to properly scale and rotate V-Ray materials and a quick link to the V-Ray Asset Editor to edit them.

In order to replace a Revit material with a V-Ray one, you first need to create V-Ray materials in the Asset Editor. Those will then become available in the drop-downs next to each material in the Appearance Manager.

If you don't associate a Revit material with a V-Ray one, the Revit material will be automatically converted to a V-Ray material during V-Ray rendering. It will use the material properties specified in the Revit Material Browser.

With V-Ray 5, update 1, you can also promote the new Revit Prism-based materials as V-Ray ones to the Asset Editor. This equips the native Revit materials with parameters specific for V-Ray Materials only, thus further expanding the possibilities for modifying them.

With V-Ray 6, Enscape materials properties are considered when promoting materials to the Asset Editor.
