Camera fade without Mobile HDR?
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!

- GRADGRProtegeCamera Fade requires HDR, then only efficient way to do this is by creating a "fake" fade widget with full screen size. This can be added to pawn camera or even to a sequence by using events.
- VRexProtegeYeah, that's what I figured. Isn't the transparency going to screw up frame rate though? I'll give it a go. Thanks, GRADGR.
- DizzzieExplorerDid you ever figure this out?
- AnonymousAn interesting new feature in Oculus' UE 1.31.0 is color scaling - https://developer.oculus.com/documentation/unreal/latest/concepts/unreal-color-functions/
If you can update the engine, I'd consider looking into achieving the effect that way. - rasamayaExplorer

This works for nice camera fades while streaming in and out levels. Great idea, thanks! Implemented in a few projects on Quest - rustbucketHonored GuestI know this is an ancient thread but does anyone have any clear instructions or a BP sample on how to do a fade using the color scale? I'm completely lost as to what the "color scale and offset" should plug into.
- allan_mcintosh_Honored GuestI am by no means an expert but this worked for me.
It's for my loading screen.
First set the play screen to black then wait 2 seconds and fade to clear via timeline then wait 4 seconds and fadeout then open new level.
Hope this helps - yannick.tholomierHonored GuestThank you!

Hi everyone, I would like to use 'Set color scale and offset' for a single mesh to fade it in. Is that possible? And does anyone know how to accomplish that? I already tried to fade-in the mesh with a: 'dynamic material instance, new timeline and set scalar parameter value', but this looks super strange in the VR headset since little dots occur when the mesh blends in. Thank you very much in advance! :-) - Anonymous

No that node doesn't work individual meshes only the whole scene (excluding widgets).
The way you mentioned should work if the material is translucent. Perhaps you're using a masked material which gets this dotty dithering effect?
