Motion Blur in Stereo - not possible in UE?


Is it even possible to have stereo view with 2 motion blurs? No matter what technique, I dont care about optimization because it will be just rendered out. I tried multiplayer splitscreen but there is no motion blur (I found that this is turned off in the engine somewhere), SceneCapture2D cameras dont receive motion blur (the only thing that is not working with postprocess), but event with it, when I put two textures from two cameras on one Main camera I have motion blur only from the main so I have in the middle a blur but the worse thing is that when I move my player the blur from objects is in the middle of the screen (I need to have 2 blurs for two eyes). I tried everything but without luck.

Is this effect even possible or this is something required black magic to work?
