Jonathan, is there a way to filter the Glossy Shader Roughness if you don't have access to the Multi-scatter GGX selection.

    The latest versions should all have Multiscatter, but if you're working on a project that needs an older version, try adding 0.5 to the color with a Mix RGB node and using the roughness value as a factor. It's not 100% the same but it's a very close approximation. Visual here: http://pasteall.org/pic/show.php?id=117006
  • Thanks for the tip Jonathan. I will give it a try. The reason for this is that my current OS/Computer arrangement is forcing me to work in version 2.76b. Again, Thanks.
