Nucleus Navigator

Interface Overview

Nucleus Navigator makes it easy to browse the data stored in Nucleus using a web browser, from Nucleus tab within the Omniverse Launcher, or by using the standalone Nucleus Navigator application. Using the standalone Nucleus Navigator application will provide the most comprehensive and feature-rich experience.

Whether adding new content, adjusting permissions or sharing content URLs, Navigator provides convenient access to files, users and permissions for any Nucleus host.

Users can also see how their permissions are inherited. With the new “resolved” [R] section in the Permissions Tab panel, users can understand where the most permissive permissions are coming from so they can adjust who can read and/or write their files.

The permissions tab allows you to control access to data. The latest feature we have added is you can now see how your permissions are resolved. This makes it easy to understand where the permissions are coming from since Nucleus supports permission inheritance.

Multiple Server Connections

Depending on how your deployment was configured, users may have the ability to connect Multiple Nucleus servers from one Navigator instance, allowing cross-server search functionality. If this feature is disabled, users will not see the “Add Server” button in Nucleus.

  • This feature cannot be controlled by regular system users.

  • Multiple server support may only be configured by system administrators for the centralized deployment in the browser.

  • For those who install Navigator from Launcher, this option is enabled by default and cannot be reconfigured.

Add a Server

To add a server, click the Omniverse logo in the directory tree. Wait for a moment for the system to search for the server connector. If multiple server connectivity is enabled, click “Add Server”.

Omniverse Nucleus Navigator Add Server

Enter the server address and click “Next”. A successful connection attempt will display the new server in the navigation pane.

Issues with server Connections

  1. Ensure that the server is actually running.

  2. Check your scheme: http v. https

  3. Remove any extraneous endpoints or services that may be trailing the address.

  4. Check your server login credentials or request permission from your administrator.

Version Control

Navigator creates and lists Checkpoints. See the Checkpoints page.

Checkpoint Rename, Move, and Copy

Checkpoints are created automatically for the destinations of Rename, Move, and Copy operations.

  • For Rename and Move the description states which source was used to replace the file contents.

  • For Copy the description states where the file was copied from.
