Camera fade without Mobile HDR enabled?

I’m trying to do some camera fades for an Oculus Go project in Unreal 4.20 and am unable to find a good way to do so without enabling Mobile HDR. I imagine that would destroy my framerate. What are the options to replace a camera fade in this case? I would do a UI or transparent animated plane but that seems like it would wreck performance as well. Would love to hear some suggestions. Thanks!

Did you ever figure this out? I keep searching for the same question and only keep find your post with no answers to it. I’m in the same boat as you, I’m not able to use mobile HDR since I’m developing for the Oculus quest. I tried a plane with a material that has a variable for the opacity mask. Than I attached that to the camera, in front, to stimulate fade in and out between levels and my framerate was cut in half, 72 fps to 36 fps.
