MtoA - aiStandard Surface: Sheen AOV Question

[awilliamsMilkVFX1]

Hi guys,
Im using the new sheen setting in Maya with the latets build of MtoA, and was wondering if there was a way to have the sheen contribution not included in the Direct spec AOV right now im getting a separated sheen AOV and in the Direct spec im getting that included as well?

can you do subtractions ? https://en.wikipedia.org/wiki/Subtraction

...Id rather not have to do that each time I comp. Surely there is a way to output them already seperated straight from the renderer its self right?

Sheen is a specular contribution. If you wanna a full direct specular aov you get also sheen there. Then yep iirc .. with standardmaterial.. the base specular is treated like a global specular while the other specular layers (coat, sheen) have their own aov .. there should be a separate aov also for the base specular probably.
