We tested to stream an USD 3D model from Omniverse Create(2021.3.8) to XR Remote(iPad Pro 12.9inch 2nd gen, sw ver. 15.2.1) via CloudXR on same network. However, the XR Remote could get the asset and disconnect.

NVIDIA CloudXR v2.2 (CL# 30238443), built on Jul 28 2021 22:49:17.

Hi Joseph, can you please clarify the problem? Are you saying that the XR Remote app from the app store did work, but then you tried using CloudXR itself and that didn’t work?

If that’s the case, I suspect the issue is that Omniverse Create 2021.3.8 and the iOS app are both using CloudXR 2.1, and you appear to be using CloudXR 2.2? These are not fully compatible, unfortunately.

The version of CloudXR is 3.1. We followed the Cloud XR User Manual to enable Omniverse Create TableAR to output to CloudXR server and view it in iOS Omniverse XR Remote. However, the iOS App could not connect/load anything from the server.

Omniverse requires use of their specific server installation and clients, which as noted above was last shipped on top of CloudXR 2.1. If you are trying to use the cloudxr public SDK to build a custom OV client, that won’t work, you’ll need to use the specific SDK version that ships with OV. If you are trying to use the CloudXR public sample code to create a client to connect to OV, again that won’t work due to version mismatch.
