Cosmos material library EMPTY

Hi, it’s been a while since the cosmos materials library has been empty for some material categories (e.g., wood flooring, wood, concrete, brick, etc.). The only materials I can still visualize and download are fabrics.

The version of Vray I am using is Vray 5 for rhinoceros.

How can I fix the problem?

Cosmos is a subscription product included with current subscriptions- given you are using V-Ray 5, I’m guessing you don’t have a subscription for V-Ray and Cosmos?

If so, then I guess these are the free ones that people with older licenses can use.
