The free plug-in is intended to make working with materials in Maya scenes considerably easier: It has an easy-to-understand user interface as well as preview images of the materials. The SLiB plug-in is compatible with Maya versions 2013 to 2016.
There is also a metal shader package with 142 metal materials for Maya and Redshift. A glass and floor package is due to follow soon.
The SLiB package is still being offered at a special price in June.
Here you can buy the metal shader package for 35 US dollars. And the free browser plug-in is available here.
