Unreal Engine 4 Integration

• First Oculus integration of Unreal Engine 4.26
• The Avatar plugin has been removed. If you require avatars, use an earlier version of the Oculus integration.
• Samples now include Handpose Showcase, providing examples for using the raw hand data provided by the Oculus Hands API. Includes blueprints and C++ code demonstrating "force grab" and "force throw" mechanics.
• To launch apps with command line arguments, you can now add arguments to UE4CommandLine by way of the new debug.ue4.commandline system property.
For example:
adb shell setprop debug.ue4.commandline "-vulkandebug"
• Vulkan shaders compile faster thanks to improved initialization.
• The amount of MSAA subsampling can now be changed by way of the standard Unreal Engine settings. Previously, MSAA subsampling was hardcoded to 4x.
• The Oculus Performance Window now checks if you have set a color space. Rift CV1 is still the default if the color gamut setting is unknown or not enabled.
• To support Oculus Crash Analytics, the default settings of the Oculus Platform Tool automatically uploads debug symbol files when you upload a build to a release channel.

• Fixed issues with VR preview where previewing on device with the mobile code path and shaders would render only the left eye or nothing at all.
• Fixed several Vulkan Validation Layer errors.

Platform SDK

• This is a maintenance release. There are no developer-facing changes in this release.

Mobile SDK

• Added a new entry point, vrapi_CreateAndroidSurfaceSwapchain3, for creating an Android surface backed swapchain by passing platform specific create flags defined in ovrAndroidSurfaceSwapChainFlags.
• The vrapi_SubmitFrame and associated structures have been marked deprecated and should no longer be used. The vrapi_SubmitFrame2 path should be used instead.
• The ovrModeFlag, VRAPI_MODE_FLAG_FRONT_BUFFER_PROTECTED, has been removed since protected mode is indicated at the swapchain level via ovrAndroidSurfaceSwapChainFlags flag VRAPI_ANDROID_SURFACE_SWAP_CHAIN_FLAG_PROTECTED.
• The ovrSystemStatus, VRAPI_SYS_STATUS_FRONT_BUFFER_PROTECTED, has been removed.

• There are no major bug fixes with this release.
