Awesome!!! That worked!
How would you go by linking that up to an Arnold Shader? From my understanding, you need to create a aiUserDataColor node and plug that into the color attribute of an Arnold Shader. I'm just not sure what to feed the aiUserDataColor node.
Also, just to be on the same page, when the color is being applied in maya, are we applying the color to points or verts. I'm assuming the gradation in color wouldn't be as smooth on verts?
Thanks again! Very excited to add arrayToPointColor to my workflow!
