Stereo Camera in Headset (Oculus)

Is it possible to render images from a Stereo camera in the Oculus. I want to render left camera to a texture for the left eye in the oculus and same for the right camera. I got all the code to get the stereo camera textures into Unreal, but I’m not sure how to setup the textures so a texture is rendered for a specific eye in the Headset.

Also how do I get around to change the fov on the fly for the Oculus?
