I have just updated to Vray 7 (update 4) for Cinema 4D 2026.3.2. When I import a Chaos Cosmos material, it displays all black in the material editor window, and it does not render. How can I solve this problem?
Are you importing them as node materials? There’s a setting in the preferences to switch back to classic materials, have you tried that? Do you see any errors in Cosmos? And does this happen with all materials or only some? Also can you please check your node space as explained here: Asset Texture issue with any assets
I’m not importing them as none materials. I’m simply opening the Chaos Cosmos browser, selecting a material and importing it. It’s happening to all imported materials (from Cosmos browser). Also, when I import a 3D object also from the Chaos Cosmos browser, its materials are also showing as all black. This is bizarre.
I found the solution to the problem. Because I just updated Cinema 4D, the default renderer was set back to Redshift. When I switched it back to Vray, the problem was solved.
