Install the VPM package here or via the Unity Package in Releases.
Open the main window in the Unity Editor Menu: Tools/Open NID.
An open source utility tool to easily manage Network IDs for VRChat worlds.

Open NID provides simple auto fixes for tedious actions like reapplying scene components to an existing network object and
clearing missing network objects from the collection. This is helpful when needing to do repeated builds with scene changes for testing.

Open NID hooks into the VRChat SDK Build API and allows the user to fix issues before the Network ID Verification process.

Open NID provides an intuitive export and import tool for transferring Network ID information between scenes and projects.

Open NID checks for network behaviours related to VRC Player Objects w/VRC Enable Persistence components to allow operations like Clear and Regenerate Network IDs to exclude persistence enabled Network IDs.

Most actions done with Open NID support Unity's Undo system and Prefab instance modifications.
