Oh sorry, that was the colimo plugin, not realcamera. I used to experiment with that plugin in modo. Personally i dont find it very practical, the render passes were skipped in the video, but it have to make a separate render for each thing you want to tweak later (that is, if you want 3 materials and 2 lights, you must wait your render time multiplied by 5) Thats the man reason why i find this tool very interesting, but not really productive.
As far as i know, only major packages are supported. I will be very surprised if octane gets a colimo plugin.
