Failed to load Windows Mixed Reality Interop Library - UE 4.23

@InceptTn

Thank you for guys for solving this (important) issue for WMR developers. It seems that the late Hololens 2 implementation messed up the UE-71625 commit (https://github.com/EpicGames/UnrealE…10e6cff7b89030).

@scadl could you please elaborate on how you rebuild the WMR plugin? I am receiving an error when using the “RunUAT.bat” batch file to rebuild the plugin “<UE folder>\Engine\Plugins\Runtime\WindowsMixedReality\WindowsMixedReality.uplugin”.

Edit: To whom it may concern, I had to build the release version of Unreal (from github) to change the WMR plugin and build the whole project. I confirm that this solution works. Cheers!

Having the same exact problem, added the lines in the .cpp, now I have no idea how to rebuild this WindowsMixedRealityInterop.Build… Can anyone specify what exactly needs to be done or at least llink me any guide on this?

Please, help us

The only thing I did, I opened the solution of this plugin (MixedRealityInterop.sln).
And (Re)Builded the same way you do this with the Engine itself.

There are two projects inside, one for HoloLens and one for WMR.
I also noticed there are only two target architectures: Arm64, win64.

In the launcher (prebuilt) version of UE you don’t have this SLN,
So I just generated poject source, modified plugin, and repackaged it.
I think this is less reliable way to fix this, because now I have problems with height detection…
Sorry, I couldn’t find the way to fix this on current launcher version of UE 4.23.1
As a temporal solution, I switched to OpenXR plugin and enabled in Mixed Reality Portal
