Tools I've used in Unity 5.x are breaking my 2017 scene... and I do not see a way to output video or frames from Cinemachine (although I am trying to understand all of its features).
What is the best way in a mandatory C#/Unity 2017 workflow to capture camera output within Unity -- not a screen grab? No postprocessing needed... just frames!
In the past I have used Renderator Pro and VR Rocks, neither of which seem at the moment to support 2017 -- using deprecated code.
SOLUTION -- ROCK VR Does indeed work with Unity 2017... although not exactly the way I have modified it for 5.x.... but going back to stock import of resources and rebuilding works well.
