Introducing Synergiz LightHouse: Integrated Real-Time Collaboration Solution
Hi everyone! Hope you're all doing well! At Synergiz (French Microsoft MRPP company) we've been creating HoloLens content since the release of the first hardware version. We experimented a lot of tools to create HoloLens applications and we're now happy to say that we know what's painful and what's not in this process. Therefore, after the deprecation of Unity Network, we decided to create our own multi-user (offline and online) solution. Today, we're proud to release "LightHouse", a solution specifically designed to be integrated into Mixed Reality applications, allowing smooth and real-time multi-users interactions. We would be delighted if you could take a look, and we warmly invite you to try it for yourself : http://lighthouse.synergiz.com/ We would love to have your feedback ! Take care Quentin LouetWelcome!
Hello everyone, and welcome to the Mixed Reality Tech Community! Please make yourself at home, introduce yourself, share a project, or whatever else! We're super excited to finally have an online community space here, so keep your eyes on it, we'll definitely be doing more with it very soon! 🙂

Open PDF Document in Hololens 2 from the file browser
I am trying to open a pdf document located in the persistent data path, in the file explorer, in the hololens 2 device but when trying to open it by c# code in Unity, nothing happens. I've tried with the code provided in the question locted inthis linkand it appear to happen an exception that sais this: "Exception of type 'System.Exception' was thrown". Does anyone know what is happening and how can I fix it? This is the code I've used to do it: using UnityEngine; using UnityEngine.Networking; using System; using System.IO; using System.Collections; using System.Diagnostics; using TMPro; using System.Threading.Tasks; #if !UNITY_EDITOR && UNITY_WSA using System; using System.Threading.Tasks; using Windows.System; using Windows.Storage; using Windows.Storage.Streams; using Windows.Data.Pdf; #endif public class PdfDownloader : MonoBehaviour { public string pdfUrl = "https://grados.ugr.es/primaria/pages/infoacademica/archivos/ejemplostfg/!"; public string destinationPath = "my-file.pdf"; int pg = 0; // Definir e inicializar la variable pg [SerializeField] private GameObject PDFPlane = null; [SerializeField] private TextMeshProUGUI text = null; #if !UNITY_EDITOR && UNITY_WSA PdfDocument pdfDocument; #endif public void download() { StartCoroutine(DownloadPdf()); } IEnumerator DownloadPdf() { UnityWebRequest www = UnityWebRequest.Get(pdfUrl); yield return www.SendWebRequest(); if (www.result != UnityWebRequest.Result.Success) { UnityEngine.Debug.LogError("Error al descargar el archivo PDF: " + www.error); } else { string filePath = Path.Combine(Application.persistentDataPath, destinationPath); SaveFile(filePath, www.downloadHandler.data); UnityEngine.Debug.Log("Archivo PDF descargado correctamente en: " + filePath); text.text += "Archivo PDF descargado correctamente en: " + filePath+ "\n"; // Abrir el archivo PDF LoadAsync(); text.text += "Abierto" + "\n"; } } void SaveFile(string path, byte[] data) { try { // Crear el directorio si no existe string directory = Path.GetDirectoryName(path); if (!Directory.Exists(directory)) { Directory.CreateDirectory(directory); text.text += "Creado" + "\n"; } // Escribir los datos del archivo en el archivo especificado File.WriteAllBytes(path, data); text.text += "Escrito" + "\n"; } catch (Exception e) { UnityEngine.Debug.LogError("Error al guardar el archivo: " + e.Message); text.text += "Error al guardar el archivo: " + e.Message+ "\n"; } } public async void LoadAsync() { string path = Application.persistentDataPath; #if !UNITY_EDITOR && UNITY_WSA text.text += "Empiezo "+ "\n"; try { StorageFolder storageFolder = await StorageFolder.GetFolderFromPathAsync(path); /*StorageFolder storageFolder = KnownFolders.CameraRoll;*/ text.text += "Empiezo 2 "+ "\n"; StorageFile sampleFile = await storageFolder.GetFileAsync("my-file.pdf"); text.text += "Empiezo 3 "+ "\n"; //pdfDocument is an instanced object of type PdfDocument pdfDocument = await PdfDocument.LoadFromFileAsync(sampleFile); text.text += "Folder path 2: " + storageFolder + "\n"; } catch (Exception e) { text.text += "1: " + e.Message; } text.text += "listo"; #endif } public async void ChangePageAsync() { text.text += "Voy" + "\n"; #if !UNITY_EDITOR && UNITY_WSA text.text += "Empiezo "+ "\n"; //pg is the page to load using (PdfPage firstPage = pdfDocument.GetPage((uint)pg)) { InMemoryRandomAccessStream stream = new InMemoryRandomAccessStream(); await firstPage.RenderToStreamAsync(stream); MemoryStream tempStream = new MemoryStream(); await stream.AsStream().CopyToAsync(tempStream); byte[] imgBytes = new byte[16 * 1024]; imgBytes = tempStream.ToArray(); Texture2D imgTex = new Texture2D(2048, 2048, TextureFormat.BC7, false); imgTex.LoadImage(imgBytes); imgTex.filterMode = FilterMode.Bilinear; imgTex.wrapMode = TextureWrapMode.Clamp; MeshRenderer meshRenderer = PDFPlane.GetComponent<MeshRenderer>(); Material mat = meshRenderer.material; mat.SetTexture("_MainTex", imgTex); mat.mainTextureScale = new Vector2(1, 1); text.text += "pg: " + pg + "\n"; } #endif } } In the code, I first download it and then try open it. The text.text are debugging lines I've added. The pdf URL is an example pdf obtained from google. I want to show using an Unity app a pdf that has been downloaded before a pdf, avoiding the limitations tah hololens 2 has when opening a local file.
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 2 - Edge - WebXR & immersive-ar mode
Hello I'm working on the Hololens 2 using WebXR / WebGL custom engine. For some reason, the latest version of the Edge browser changed WebXR behavior, now "immersive-ar " context is no longer supported, only "immersive-vr" Even BabylonJS WebXR demo are broken, as features such as Depth-sensing are not supported in vr mode. Is there any reason why ? Best, Matt

Hololens 2 QRCode Sample in MRTK3
Hello. For an application we built in our laboratory, we used MRTK 2.7.2 and this samplehttps://github.com/microsoft/MixedReality-QRCode-Sample, with unity 2021.1.22. The sample works really well in our case. Now, we are creating a new application with latest version of MRTK3 and Unity 2021.3.19, but seems that the sample doesn't work with MRTK3. Is there a way to let it work with MRTK3? Thank you, Nicolas.
