Hi all,
As of 26 October, Chaos Cosmos added new category Materials with 200 items in sub-categories: Bricks, Concrete, Fabric, Ground, Leather, Metal, Roof, Stone, Tiles, Walls, Wood, and Wood flooring. You can see the extensive list on this link.
Cosmos Materials are included in V-Ray 5 for 3ds Max update 2, and will come with each next V-Ray release later this year.
As always, we look forward to receiving your comments and requests.
Best Regards,
