Hello!
I was trying to create a "Point World Reference Pass" with Ornatrix in Maya 2016. I'm rendering in Vray for Maya, and it seems that the base mesh that I have the hair growing from renders correctly. But the hair doesn't carry the information with it. Is there a node or an update that can be made to address this?
Here is an example of it working on a base mesh.

I've got it working in Yeti, but I was able to create an attribute in my Yeti fur node chain that passes the point world information to the hair geo that is created.
