UE4 switch eye rendered to spectator screen

Hi there,

I'm working with a DK2 in
unreal engine, and I really need to figure out how to change which eye
is rendered to the single eye spectator screen so that I can record
some  footage. There are a few modes which show both eyes, but all the
single eye modes default to the left eye and for my application I
absolutely need it to be the right eye.

I
saw this post on the unreal forums about editing .cpp and recompiling
for the Vive, but I have no idea what files I would have to go about
editing for the DK2, or how to recompile anything.

Not
allowed to post links so the name of the thread is "Problem about
monitor resolution display in vive vr mode" if anyone is curious.
Essentially it just says to edit the line of code relating to the
`DrawRectangle` function and changing the values so it selects a
different area to crop.

I would really appreciate it if someone could help me.

many thanks,
