Displacement mapping is a technique for adding detail to geometric objects without having to model it first. The concept is very similar to bump mapping. However, bump mapping is a shading effect that only changes the appearance of a surface, while displacement Displacement mapping actually modifies the surface.

The image slider on the right shows the effect of the Displacement mapping.

• Create a Displacement geometry in the Asset Editor from the Geometry drop-down menu or from Create Asset > Geometries > Displacement and assign a texture to the Map slot.
  Currently, the displacement Displacement geometry is not assigned to any object in the Revit model and it is not visible during rendering.
• In the Appearance Manager, navigate to the material that needs displacementDisplacement.
• From the V-Ray drop-down menu next to it,  select select Displacement. A grey dot indicates that the Displacement is assigned to that material. All objects that have the material assigned to them also acquire the Displacement.

• A drag-and-drop option is also available for assigning Displacement to any material in the Appearance Manager.
• Materials with assigned Displacement can be filtered from the Filter icon (Image Added), which is located in the search window.
