Its probably a beginner/noob question but does anyone have a tutorial or place of reference I can use to convert an older shader I
made from a Maya Blinn shader rendered with Mental ray to a Principle shader that can be rendered with mantra?

not THE material but material. What I was saying is that in a physically based ray tracer, material is a set of algorithm that defines a physical surface/volume's behavior of reflecting/absorbing/scattering light. As far as I know, mental ray is an outdated renderer that's not physically based, and mantra, like arnold is a physically based physical renderer. I hope this answers your question.
