Substance to Maya 2016 Arnold to Substance to Maya 2018 NEW Arnold

#1

helloI have made materials in substance painter 2.41 and have exported everything for arnold shaders in maya 2016 with Arnold for Maya 1.2.6.1
It is all looking great.
My question is: I am switching to Maya 2018 and will be using the latest version of Arnold.
How should I deal with my shaders? Is there a new way to export out of substance painter to be used in the latest arnold? Because I hear it is very different?
OR do I have to just convert my shaders from maya arnold old to maya arnold new (I heard this was very different and the results are not good)
please help!
