As became apparent after my attempt to answer to a recent BSE Question..
It seems that Dupliframes are not rendered in Cycles Preview or Final? (They are rendered by Blender Internal)
This is true of two recent builds of 2.79. Windows 10, Nvidia 840m
Is this just a missing setting, expected behaviour, or a bug?
If it is a bug, is bug reporting still accepted for Blender 2.79, or has everything moved on to 2.8?
