HL2 Holographic Emulation - Hands tracking not working

    Unity 2019.4.3f1 (LTS)
    MRTK 2.4.0 installed

    Trying to set up HL2 with holographic emulation; works nicely with the deprecated framework but I'm not getting the articulated hands - I can see a gameobject created for the hand (right/left) but no movement. And when I switch to the new XR SDK I'm getting hands but remote window disconnects every time I stop playmode and I'm getting some strange exceptions (null reference on something called _unity_self and memory leak on native collections - with a crash every once in a while). I'd love to work with the new SDK obviously but if not then how do I get articulated hands from the deprecated holographic emulation?

    For anyone interested; I've not managed to get the new holographic remoting to work properly (or even stably) with the HoloLens 2 device. So I've reverted back to the deprecated version. That said, there seems to be an issue with the MSBuild for Unity package in Unity 2019.4 so I had to download a nuget client designed for Unity and manually get the required DotNetWinRT.dll dependency. Can follow the instructions here: https://microsoft.github.io/MixedRealityToolkit-Unity/Documentation/Tools/HolographicRemoting.html

    Hello,

    Which version of the Windows SDK did you install? The only thing we can think of at the moment is perhaps you have the wrong version of the SDK installed. To our understanding, DotNetWinRT.dll is shipped with Windows so you should not have to add this manually. Have you brought up this issue to Microsoft as well?
