Is there any way to get only the camera? I wanted to use OpenXR and wanted to get the camera function similar to SRWorks

@Kyle C Ok, one more question. How do you enable the hand tracking mode for Vive Pro? I know that for Focus 3 you needed to allow it on the networking settings.

@Kyle C Ok now it is enabled but it is still not like your picture in tutorial and neither the passthrough are working. Do I have to set another setting for the camera? Oh yeah, and I tried to get the log from pack log and it results in nothing, do I need to select the folder the project is on or select an empty folder?

@KyleC If you want to recreate it, here's my steps using Unity 2021.3.2f1: Scene Understanding: 1. Package Manager install com.unity.xr.management and com.unity.xr.interaction.toolkit 2. Package Manager register vive registries: VIVE http://npm-registry.vive.com com.htc.upm 3. Package Manager install com.htc.upm.vive.openxr and import SceneUnderstanding sample or make custom SceneUnderstanding via your tutorial (which actually have an error which is ConvertTransform where you never put it in your tutorial) 4. Play the scene. For me whenever I play the scene it will always make the MeshBehaviour.cs disabled like the picture on my previous reply and also sometimes crashes when I turn on the vive console. SRWorks: 1. Package Manager install com.unity.xr.management and com.unity.xr.interaction.toolkit 2. Import srworks package *IMPORTANT: DO NOT IMPORT STEAM VR OR VIVE OPENXR, because it will made you cannot accept the settings provided by srworks package when you change your scene. 3. Play For me when I play the scene it displays the camera passthrough on the game screen, but it will display nothing on the vive pro 2. The game screen on Unity also went blank when I tried to change the room view setting on SteamVR, and whenever I tried to play the scene again it will still be blank regardless if I try to change my vr room view setting back on the previous one again.

@KyleC Hi Kyle, haven't heard from you. Is there a solution for the problem for SceneUnderstanding I'm currently having?? And do you know what happened for my camera at SRWorks to go blank?

Finally after some bits of tweaking, the SRWorks is working. But it still have some bugs. First of all you cannot install any other VR package other than com.unity.xr.management and xrcom.unity.interaction.toolkit. Even if it is from comhtc.upm.vive.openxr, because it will make the vive settings not working and you have to make another new project. Secondly my bug was, when I try to change the room view, the passthrough doesn't work anymore and it only display blank screen on Unity. Thirdly my Scene Understanding is still not working

For Number 1, I already did set the settings for the Camera and also the developer function for OpenXR. I am using VivePro2 and I also already tried running it with OpenXR without your samples and only the XR Rig which is the default VR package for Unity and it works fine. But not for any of your samples. Here's the Camera Settings Here's the Developer Settings As for step Number 2, the SRWork Runtime does not appear in my Taskbar. Your tutorial also did not mention any apps other than vive console to install. So, I was wondering if there are any other tutorial that I am missing, because from what you have told me I definitely have a step that I didn't do which definitely I didn't see in the tutorial. And also regarding my original question, which is the script of MeshingBehaviour.cs from your sample or in my project is called SceneUnderstanding_Sample.cs still kept disabling itself be it from your sample or creating my own through your tutorial. As you can see from here. Regarding your question for Vive Console installer. I tried two of your installation from Online and Offline Vive setup from your website. and yes, none of the samples I mentioned works in any of them.

Hi, I wanted to ask about why does the Scene Understanding Example not working out for me. I am using Unity 2021.3.2f1 and have also added the OpenXR Vive Plugin, but still cannot play the demo sample. Then I tried to not use the sample and just make a custom one like the tutorial, but the script kept on disabling itself because it cannot found any XRMeshSubsystem using SubsystemManager.GetInstances(). Is there anything that I'm missing?? Oh yeah, this is also the setting for OpenXR Plugin Management Here's my script for MeshingTeapotFeature using System; using System.Collections; using System.Collections.Generic; using System.Runtime.InteropServices;

I also tried the example for SRWorks and I also can't get it to Play.
