I had two icons, and they both go to the same place. I had an icon going to the materials, and one going to Cosmos. Now both icons go to Cosmos. It isn’t nearly as conveniet to find materials without the dedicated icon. Ha ssomething changed?
We are transitioning the materials distribution to Cosmos. If you already have the old library on your machine it should work as before (with the legacy browser). Please check this thread - Vray Material Library Browser - V-Ray for 3ds Max :: General - Chaos Forum
We’ll make the Materials Browser button go directly to the material section in Cosmos in the near future.
