I’m trying to get a remotely pre rendered scene be shown on screen. I have a stereo texture generated at runtime and I want it to be drawn fullscreen in VR. I can use a PostProcess material on desktop but unfortunately this is not supported on mobile (Oculus Quest) because it requires MobileHDR. I tried render it into the Viewport via Slate/UMG but it gets weirdly clipped in screen space, see the attached screen in which you can see the small window streaming to the big one and the streamed texture is drawn either onto the cube in the scene and to the viewport, but it gets clipped into a weird screen region.
Now the question is: how to do it? How to draw this texture to fully cover the viewport?
Possibly in a cross platform way
