Stereo - Inversed depth

I would like to display one of my projects on my 3DTV, (with SideBySide 3D) but plugins like the SimpleHMD, and startup commands like -emulatestereo always deliver a faulty image, it seems that the right and left eye are inversed but even in changing that manually you still have to squint…

This Screenshot is right out of the engine:

The City in the Background is far away and should be identical… if i export a stereo panorama with the new plugin the depth works perfectly (but unfortunately not the format i need :frowning: )

I hope someone can help me with this, i searched the entire day for a solution without luck :confused:

i´ve encountered this issue in ue 4.7, 4.11 and 4.12 (so basically in every version i tried xD)
