Page History

This allows you to search for materials. Note that if a Revit Identity Class name is inputted in the search bar, only the materials belonging to that class are displayed in the list below.

You can also choose from the following options in the Filter drop-down menu:

Show Materials

All – Lists all materials in your project.

Used in project – Lists all materials in your main Revit file, i.e. hides all linked files materials.

Latest Render – Lists all materials that were exported by V-Ray during the latest render you have done.

Prism only – Lists all Prism-based materials, i.e. all materials that can be promoted using the Promote Revit materials as V-Ray ones functionality.

V-Ray Mapping

All – Lists all materials, i.e. the V-Ray Mapping filter is not applied.

Mapped – Lists all materials that have been replaced with a a V-Ray Material.

Unmapped – Lists all materials that have not been replaced with a V-Ray Material yet.

Transparency

All – Lists all materials, i.e. the Transparency filter is not applied.

Opaque – Lists only the opaque materials in the project. 

Transparent – Lists only the transparent materials in the project.

V-Ray Grass/Fur

All – Lists all materials, i.e. the V-Ray Grass/Fur filter is not applied.

Mapped – Lists all materials that have been assigned a V-Ray Grass/Fur.

Unmapped – Lists all materials that have not been assigned a V-Ray Grass/Fur.

V-Ray Displacement

All – Lists all materials, i.e. the V-Ray Displacement filter is not applied.

Mapped – Lists all materials that have been assigned a V-Ray Displacement.

Unmapped – Lists all materials that have not been assigned a V-Ray Displacement.

Right-click on the filter icon, resets the filters to their defaults.

When you click on the Pick Material button (), and select a surface in the Revit model, you can see only its material displayed in the material list.

Note that the option works only on surfaces that are native for the Revit model and does not work for linked models.

These settings allow you to control the scale, rotation and offset of all maps that a V-Ray material comprises. Use them after you replace a Revit material with a V-Ray one to match the V-Ray material's map size with your project scale.

Width/Height  – Set the width and the height of the V-Ray material.

Rotation – Rotates the V-Ray material (in degrees). 

Offset V/H – Controls the V-Ray material offset in the vertical (V) and horizontal (H) direction. 

The Linked replacements settings allow you to specify whether V-Ray material replacements coming from linked files are treated with respect to the host file or to the linked file:

Discard – All linked V-Ray replacements are discarded. This allows for overriding the materials/families in the linked file.

View & Override – Linked V-Ray replacements can be viewed, rendered or overridden with V-Ray assets created in the host project.

Read-only – Linked V-Ray replacements are rendered but are hidden from the list. An override is not allowed. This mode can be used for reducing the list in the Appearance Manager.

Merge identical – When enabled, identically named items are hidden from the linked file list(s) and remain listed only in the main project section. Their replacements are based on those of the host project. For example, if Bricks_01 material is present in both the host and linked projects and Merge identical mode is enabled, Bricks_01 will only be visible in the Project group of materials. But when replaced with a V-Ray material, it will also override the Bricks_01 material of the linked project.
