UWP app network connection blocked by hololens 2 windows firewall
Hello, my UWP app, which was installed on the HoloLens, has encountered an issue and is now unable to connect to the internet.I checked the hololens diagnostic log and it stated the following event: "Windows Defender Firewall was unable to notify the user that it blocked an application from accepting incoming connections on the network. Reason: The application is non interactive Application Path:.....". My development setup includes Unity 2018.4.11f1 and Visual Studio 2019. The capability setting in AppxManifest file is: <Capabilities> <Capability Name="internetClient" /> <Capability Name="internetClientServer" /> <Capability Name="privateNetworkClientServer"/> <uap:Capability Name="documentsLibrary" /> <uap2:Capability Name="spatialPerception" /> <DeviceCapability Name="webcam" /> <DeviceCapability Name="microphone" /> </Capabilities> The application tested all OK in unity editor but when loaded to hololens it failed to establish a network connection. Does anyone has any idea why the app has been blocked by hololens firewall? Thanks

HoloLens 1: Gestures not recognized in Unity 2019.4 with MRTK 2.8.3
I own an HoloLens 1 and so far I have developed some AR projects with Unity 2018.4.23f1 using the HoloToolkit (the version available in 2018). Now I want to develop a new project for HoloLens 1 with Unity 2019.440f1 LTS and use MRTK 2.8. I also use Visual Studio 2017. I created a new project and followed Microsoft's instructions on how to install and configure MRTK 2.8.3 (for example, I followed Microsoft manual "Set up a mixed reality project in Unity with the Mixed Reality Toolkit"). I added the MixedRealityToolkit to the new scene I created. For the MRTK Profile configuration, I selected the DefaultHololens1ConfigurationProfile. In the Input section, I activated the InputSystem and selected the DefaultHoloLens1InputSystemProfile. To verify that everything was correctly configured, I added to the scene a 3D cube, and, following Microsoft suggestions, I added the ObjectManipulator and NearInteractionGrabbable components to the cube. When I connect the HoloLens 1 to Unity through Holographic, I correctly see in the Hololens 1 the cube in the scene. Also, if I move the pointer over the cube, it correctly detects the presence of the cube. However, no gestures are recognized and therefore I cannot have any type of interaction with the cube. Even adding a bounding box with handles doesn't change the situation. The handles are recognized (their icons change) by the pointer, but then gestures are not identified and the presence of my hands in the FOV is not detected. I tried creating a new project several times starting from scratch, changing profiles and configurations, but the result is always the same. Is there something I'm doing wrong or missing? thank you for your help

Establishing an absolute world coordinate system
I am currently working on a project using the HoloLens 2, where I create a primitive that offsets a spatial anchor in a certain direction and distance received from a client socket I have in my scene. However, I am having problems with the coordinate system. Each time I open the application on the HoloLens, the coordinate system changes based on the direction I am standing since the headset is always taken as the origin. I am struggling to figure out how to establish an absolute coordinate system that I can use and stay consistent inbetween scenes. I was looking at the MRTK documentation and found the World Locking Tool (WLT), and I am curious if this may be my solution. I was curious if anyone else has experience with WLT, especially for this type of application, or knows another possible way to establish an absolute coordinate system between sessions. This is where I was looking for the WLT -https://learn.microsoft.com/en-us/windows/mixed-reality/develop/unity/spatial-anchors-in-unity?tabs=wlt
3d model quality different in unity and hololens
Hello I'm developing an application for Hololens 2 and I'm having a problem with the quality of the 3d model when I run it on Hololens 2. In Unity, the quality of the clothing animation is good (image on the left) but when I export it to hololens (image on the right) the quality decreases a lot. Could anyone help me with this problem?
