Okay, thanks! I asked about this issue on the Redshift forums. Let’s see.
Usually, if the plugin is not showing up on the list of available renderers, then I should update my Nvidia drivers. So currently that’s what I am doing. But if the drivers are not up to date, should the redshift plugin work for Maya 2016 when it is not for C4D? Ugh, I don’t know.
Let’s see if it works after the update.
