Hi ilyamar,
Thank you very much for inviting me to your project, glad to reach you again.
Although I have done this several times (Unity 3D also UE4) the failure of linking OVR camera to some movements it could be due to different factors. I think it would be best that you let me check your project file, and thus be able to guarantee whether can be done or not; in any case offer an alternative.
Let me know your thoughts, I will be looking forward to serving you.
Best regards,
Marco
