Please Help: Custom Arnold AOV's black

#1

I am using Maya 2016 and Arnold 4 (sorry).

When I create a custom aov it is black. Nothing in the alpha and none of the objects show up? How can I create a custom AOV and why won’t the objects show up?

Thanks!

Ps. The reason why I haven’t upgraded to the latest yet is because I have some very complex shaders that I dont have time to update into the latest maya and arnold which is not backwards compatible with old shaders.

What’s the purpose of the custom aov, what are you trying to accomplish? A matte pass? If so, perhaps this will help:
