Hello, I was following a tutorial by Adam Skutt that utilized the alHair shader with Arnold 4. I'm using Arnold 5 with Maya 2018 using the aiStandard hair shader instead and trying to figure out how to render out a base color pass of my hair.
I'm using melanin to color the xgen hair, and can't figure out how to render a flat color pass (without influence from shadows or spec). Every AOV option available that seems related to color renders as black. There was an AOV option called "diffuse_color" that worked with the alHair shader in Adam Skutt's 2017 tutorial, but it doesn't exist in Maya 2018. The Beauty render pass has the color so the renderer has to be getting it from somewhere.
