Hi everyone. I’ll update the git on monday with the following updates:

  • Unreal 4.22.2
  • SteamVR compatible
  • HTC Vive camera access
  • Thoroughly tested with Oculus Quest
  • Highlight selected object compatible with Oculus Quest
  • A lot of other small things

Here are more infos:

Features compatibility:
Oculus Rift / S

  • Avatar: Oculus Avatars or Custom Avatar
  • Multiplayer: Oculus Home, or Steam / LAN (Custom Avatars only)
  • VOIP: Yes

Oculus Go / Quest

  • Avatar: Oculus Avatars or Custom Avatar
  • Multiplayer: Oculus Home (Go only, Quest developers need access to Quest API)
  • VOIP: No (Oculus Avatars), Yes (Custom Avatars)

HTC Vive

  • Avatar: Custom Avatar
  • Multiplayer: Steam / LAN
  • VOIP: Yes

DO I NEED TO MAKE MODIFICATIONS TO THE ENGINE?

What are the best Project Settings for VR?

  • You will find the best settings already set in ProjectSettings

  • Oculus Go / Quest: 4x Mobile MSAA is hardcoded, no matter what

  • Oculus Go works in OpenGL ES2 and ES 3.1

  • Use Android SDK 21, 32-bits Android libraries (armeabi-v7a)

  • Advanced APK settings:

  • Oculus Quest works in OpenGL ES2 and ES 3.1, and Vulkan

  • Disable FFR and Mobile Multi-View if using Vulkan

  • Quest supports arm64, but Oculus Avatars & Mobile Audio plugin are 32-bits
    [LIST]

  • Select armeabi-v7a, Android SDK 23

  • Performances:

  • ES 3.1 + FFR + Mobile MultiView > Vulkan

[LIST]

  • ES3.1 is recommended
