Isaac Sim freezes when clicking on "start OpenXR"

[koehneiph]

Hello, I'm trying to get your Extension to work in NVIDIA Isaac Sim but it immediately freezes the whole Program when I click on "Start OpenXR" in the Extension GUI. I already tried different ways to install your Extension (provided .zip file and Extension manager) but the behavior is still the same. My System Specs are :

• Ubuntu 20.04
• Isaac Sim 2022.1.1
• SteamVR 1.26.6
• HMD: Valve Index

the last terminal output after Isaac Sim freezes shows:

any help would be really appreciated!

Hi @koehneiph

Could you please try the steps described in this post:

From the screenshot, I can see any error. Could you please share Isaac Sim logs?

Hi @Toni-SM

Sorry for my late reply. I made some progress and I can confirm that your extension is working for me in Isaac Sim 2022.1.1 using a HTC Vive Pro 2 together with the monado OpenXR Runtime. However, when switching to Isaac Sim 2022.2.1 the extension is failing to create a viewport with the following Error message:

[Error] [omni.kit.window.viewport.plugin] Legacy viewport window is being created as 'Viewport Legacy' instead of 'Viewport'

Do you know how I can enable data logging in a Standalone application?

Hi @koehneiph

The problem is that, starting with Isaac Sim 2022.2.0, the viewport API has changed and I have not been able to update the extension to use the new viewport API.

I plan to update all extensions during my August vacation. Sorry for the inconvenience

Hi @Toni-SM

alright, I already thought that the problem might be related to changes in the API...
However, I would really looking forward to seeing this add-on working again in Isaac Sim 2022.2.0! If you need testers for the new updates, let me know.

Hello, @koehneiph Could you give me some guidance how to connect HTC ViVE to ubuntu and isaac sim 2022.1.1. I have the the steam &steamVR source library problem. Because in the environment of isaac-sim, the error occurs it can not find the library of steam&steamVR but if I run the hellovr example outside the environment of isaac-sim, the HTC ViVE works well referring to https://github.com/ankurhanda/HTC-Vive-Setup-Ubuntu,
which includes a command (source run_openvr.sh
)step of source library for running steamserver

Hi @Rongyu68

Is the OpenXR runtime configured as indicated in point 2 in #4 (comment)?

Thank you for your reply. My error is not that. Do you know how to deal with this problem？
