Currently, Conductor does not support Render Setup introduced in Autodesk Maya 2016.5.
Until this feature is supported, we need to set Autodesk Maya 2016.5 and beyond to use the Legacy Render Layers.
In Autodesk Maya, navigate to the Windows pulldown menu and select Settings/Preferences -> Preferences.
In the Preferences Dialog, navigate to the Rendering Option
In the Preferred Render Setup System: pulldown list, select Legacy Render Layers.
Accept the Render Setup System notification.
And then select Save to set the override.
Restart Autodesk Maya for the override to take effect.
