The Navigation toolbar is accessible only inside V-Ray for 3ds Max 2019 , 2020, and 2021later. Due to browser limitations, there there is no plan to port the Navigation toolbar in older in earlier 3ds Max versions.

The Import options are accessible in 3ds Max 2018 and earlier versions from the Image Added dropdown button in V-Ray Toolbar instead.

Starting with V-Ray 6, update 2, the Chaos Cosmos library lets you import realistic IES light profiles.

HDRIs

The HDRI assets create a Dome Light with a VRayBitmap attached to it.
If a VRayLight (Dome) is already present in the scene, the drag & drop option creates a new VRayBitmap attached to it. Note that the cursor should be placed on the light itself when drag & dropping.

The drag & drop functionality can be used to replace an already existing VRayBitmap asset. To do that, open the Material Editor

 and drag & drop an HDRI asset from Chaos Cosmos Browser to the

file path field of any VRayBitmap.

Materials
...
 Section
 Column
width55%
The Materials section contains an array of pre-made materials, such as wood, metal, glass and others. It also contains Decals, which can be used to simulate dirt or stickers on objects.
Once downloaded, materials can be imported via the Import button. If there is an object currently selected, the material is applied directly to it. Otherwise, the material is imported into the Material Editor. Alternatively, dragging onto an object in the scene or directly into the Material Editor also imports it.

Click the green arrow Image Added for two additional import options.
Use triplanar mapping – Enables triplanar mapping on VRayBitmaps (when adding the material to a scene or selection).
Use real-world scale – Enables real-world scale mapping for VRayBitmaps (when adding the material to a scene or selection).
 UI Text Box

When an option is enabled in this menu, a blue circle (Image Added) indicates the custom setup is in effect for any further material imports.

3D Models Presets

 Section
 Column
width35%
The 3D Models category includes some Presets that work with Chaos Scatter.
When one of the presets is imported, a Chaos Scatter instance object is created. It distributes the model over the target area or spline.
These presets require existing selection of spline or surface as a guiding object for the scatter. You can either select the spline or surface and import the preset, or drag the preset from the Cosmos browser directly to the selected spline or surface of your choice.
As with other scatter objects, you can adjust the density, variation, etc.

 Section
 Column

The Enmesh-Pattern category includes Enmesh patterns that can be applied to the geometry in the scene.
When an Enmesh asset is imported, a pattern is created in the scene. It can then be added to a VRayEnmeshMod as a mesh object, which is repeated on top of the underlying geometry.
If an object is already selected, the mesh is applied directly to the selection. Alternatively, the Enmesh pattern can be dragged onto a geometry in the scene to apply it to the selection.
The imported pattern can be edited as a VRayEnmeshMod, in the Modifiers of the underlying geometry.
