Omniverse USD Resolver
Omniverse Client Library
Omniverse Asset Validator
203.0 Point Release
Release Date: June 2023
With this release the shipped USD version is updated to 22.11 and Python 3.10 to align with the rest of the Omniverse platform. Also a skinned skeletal mesh example was added to demonstrate how to author, skin, and animate skeletons in a live layer.

Omniverse USD Resolver
Omniverse Client Library
Omniverse Asset Validator
200.1 Update
This small update to the Connect Samples fixes some simple bugs in the live session classes and updates the Omniverse Client Library and USD Resolver with the latest versions.
Samples
Fix the “MESSAGE” message type and custom “message” key to be case correct
Ensure that we flush live layer clears with omniClientLiveProcess()
Clear the peer users in LeaveChannel() allows for recycling the class

Omniverse USD Resolver
Omniverse Client Library
200.0 Point Release
The 200.0 release signifies big changes with the distributed Omniverse libraries. The Omniverse team has separated the USD resolver plugin from the Client library to make it easier to support more versions of USD. Live synchronization is improved for the purposes of performance, simultaneous editors, and supporting the entire USD layer editing feature set. Omniverse applications and Connectors are also now subscribing to the notion of live sessions to support non-destructive workflows. This version of the Connect Samples includes new Python and C++ examples to demonstrate this live session workflow.
104.1 Point Release
Samples
Added physics to HelloWorld sample to showcase UsdPhysics usage.
Added the file hash to the stat output in OmniCLI
Added “cver” command to print client version
Change the live rotations from ZYX to XYZ and all xform ops to double3
Omniverse Client Library
1.17.4
OM-47554: Downgrade some “Error” messages during auth to “Verbose”
We attempt to connect using 3 different methods, and it’s normal for 2 of them to fail. This avoids confusing users with error messages for a connection that ultimately succeeds.
OM-48252: Lower required “list2” version, to allow connecting to servers running Nucleus 112.0.
1.17.3
CC-357: Fixed a deadlock that could occur when a python file status callback is being unregistered on one thread while another thread is simultaneously trying to call that file status callback
CC-367: Allow stat & list using cloudfront.net URLs

OM-33753: Fixed “running massive amounts of live edits together causes massive amounts of checkpoints”
- OM-34432: Fixed “[Create] It will lose all data or hang Create in live session”
These were all the same underlying issue: When a layer is overwritten in live mode it was cleared and set as ‘dirty’ which would cause the next “Save()” (which happens every frame in live mode) to save the cleared layer back to the Omniverse server.

Note this change means live updates no longer work with usda files (though they technically never did – it would silently convert them to usdc files).
