Substance Output Node Not Supported by Redshift - Maya

Hi! I am attempting to use the Substance Plugin for Maya to generate my hyper-shade network for Redshift. However, whenever I try to render the scene I get the error message "(substanceOutputNode) is not supported by Redshift." I was able to get Redshift to render the scene perfectly fine once time before it returned to giving me error messages. Any help would be appreciated!
