Unreal bugs/errors with Rift/Go/Quest and their status
I've made a list of current bugs/errors encountered in Unreal when developing for Rift / Quest / Go.
Some can be somewhat fixed / avoided, some are still very present. I encourage people to add to the list or bring their solution.
Would be great also to have input from @NinjaGaijin and @Ross_Beef on their possible ETA or resolution. ;)
This is up-to-date with latest Unreal (4.22.2) Oculus integration found on github, dating back from June 7.
There it is:
5. Multiplayer Oculus Avatar is broken with official Oculus Avatar Plugin
8. Performance issues when a Render target is added to Spectator screen (VR) in a packaged game

This is up-to-date with latest Unreal (4.22.2) Oculus integration found on github, dating back from June 7.
There it is:
1. Retrieve Oculus ID and Verify Entitlement fail on Go/Quest
a. STATUS: can be fixed by changing a line in OculusIdentityCallbackProxy.cpp. See at the end of list for complete solution.
b. Reference: https://developer.oculus.com/bugs/bug/2343978258981741/
2. Entitlement fail on Quest if no access to Quest API
a.STATUS: can be fixed by commenting out a line in OculusMobile_APL.xml. See at the end of list for complete solution.
3. PlayDynamicForceFeedback has errors when nativizing assets
a. STATUS: can be fixed by changing \Engine\Source\Runtime\Engine\Classes\GameFramework\PlayerController.h
line 1053 private to public, because 'PlayDynamicForceFeedback' is a private member of 'APlayerController', for reasons unknown
b. Reference: https://answers.unrealengine.com/questions/831405/playdynamicforcefeedback-node-in-420-fails-to-cook.html ;
4. Oculus Go/Quest : No VOIP / or no LipSync with Oculus Avatars
a. STATUS: NOT FIXED
b. Reference: https://developer.oculus.com/bugs/bug/471102320355137/ ;
c. Background infos: Android only allows access to the microphone from a single process. This wasn't an issue when networking avatars previously, as the mic input wasn't being used. But with the expressive update, we specifically need to run the mic through the OVRLipsync plugin to generate blend-shapes and drive the mouth shapes. Trying to hook up the mic to both VoIP and Lipsync therefore causes an inevitable race condition. The loser gets a bunch of zeros. So either there's no networked audio, or no blend-shapes.
5. Multiplayer Oculus Avatar is broken with official Oculus Avatar Plugin
a. STATUS: NOT FIXED
b. Use our in-house patched plugin/template, or use Photon Engine
6. Oculus Rift / S: Enabling Splash in Project Settings / Oculus Settings crash when loading next level
a. STATUS: NOT FIXED
b. Use blueprints to Set and Show Splash Screen
7. Stereo Layers are transluscent in ES3.1 (Oculus Go/Quest) / Vulkan (Oculus Quest)
a. STATUS: NOT FIXED
8. Performance issues when a Render target is added to Spectator screen (VR) in a packaged game
a. STATUS: FIXED IN 4.23
b. Reference: https://issues.unrealengine.com/issue/UE-70352 ;
c. IN 4.22, don't use Spectator Screens, or use them only in editor:
9. Cannot access Oculus Quest platform features
a. STATUS: You have to be greenlighted by Oculus before doing so or Oculus Business users will have access to Business Suite Q3-4 2019
10. When a stereo layer is present rendering a widget it cannot be destroyed.
a. STATUS: NOT FIXED
b. Reference: https://answers.unrealengine.com/questions/829084/stereo-layer-isnt-destroyed-on-end-play.html ;
c. Avoid using stereo layers if you need to destroy them
11. Quest: Oculus Avatars and Oculus Audio use 32-bits Android libraries (armeabi-v7a); no arm64 librairies available
