Chaos Cosmos Content System delivers a 3D content library of high-quality 3D content selected from the rich V-Ray ecosystem. It allows V-Ray users, from their respective V-Ray products, to browse, place, and render 3D assets in their projects. The asset categories span across Furniture, Accessories, People, Vegetation, Vehicles, HDRIs, and more. In addition, the assets work seamlessly in the different Chaos renderers (V-Ray, V-Ray GPU, Vantage, Corona, and Vision) and host apps (Houdini, 3ds Max, Cinema 4D, Maya, Revit, Rhino, and Sketchup).

Chaos Cosmos Browser is part of the installation of V-Ray and does not require any other specific actions. You can access the downloadable content of the Chaos Cosmos Platform from within the host platform after the V-Ray installation is completed.

Assets: Note that the Cosmos geometry is imported as V-Ray Proxy. You can refer to the V-Ray Proxy page for additional information. Any material in the scene can be used to override the shader and allows for quick customizations of the scene. You can find the newest assets in the Recently added section of the Cosmos browser.

HDRI: The HDRI assets create a Dome Light with the hdri file attached to it. It is recommended to use VRayPhysicalCamera when using Cosmos hdri files for lighting. Alternatively, you can lower the dome light intensity.

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 obj network. Inside the pattern node, a mesh object can be created to receive the pattern.

If an object is already selected, the mesh is applied directly to the selection.

The imported pattern can be edited as a V-Ray Enmesh node of the underlying geometry.

For more information on Enmesh, see the How to Add V-Ray Enmesh tutorial.
