Hello Mike,
if/when you get a chance try out Unicorn Render (unicornrender.com); in my opinion, it's fantastic how well it deals with physical-based lighting conditions and materials. Kindly note though, it's a Windows only standalone rendering software AND requires a good nVidia GPU (any 1000-series, such as a GTX 1070 or better yet 1080, 1080Ti).
Best!
Diego
