  • UE4.19 with Mobile Multi View Direct enabled app shows black screen.
  • UE4.19 with Mobile Multi View Direct disabled app shows game scene.
  • UE4.18 with Mobile Multi View Direct enabled app shows game scene.

Did someone experience similar behavior ?

Yeah I found the same thing just now. Black screen with multi-view direct on. But I turned off both mobile multiviews and then it was fine (I’m trying just turning off multiview direct, but leaving standard multiview on now)

Yeah it works with multi-view direct off. But now both SetGVRHMDRenderTargetSize and “vr.pixeldensity” cause the black screen. So we’re stuck running at native resolution is like 4x the pixels…
