USD for Maya v0.28.0 Release Notes
Release Highlights
Layer locking
This update introduces layer locking. You can now work confidently without concern of editing in the wrong layers.
- You can lock or unlock one or more layers with the lock icon in the USD layer editor.
- This lock state is saved as part of the Maya data, ensuring its persistence even after reopening the project.
- Administrators can enforce system-level locks on layers, preventing standard users from unlocking them. This can be done via Mel or Python scripts, or by locking the USD file on disk. The system-locked layers are easily identifiable by the disabled lock icons. Note that system locks are not saved as part of the Maya data.
Other Improvements
- Added the ability for setting the type of the root prim to either Scope or Xform in the USD Exporter.
- Added several callbacks related to loading stages and layers to provide mechanisms for TDs to run layer locking logic.
- Added the ability for choosing multiple job contexts from the Plug-in configuration section in the USD Exporter.
- Added ability for plugins to include their own UI to be supplied to a job context and exposed alongside the context in the Plug-in configuration.
- Added new command to query version information of the Maya USD plugin.
- Exposed missing export options to Export Chasers.
- General stability and performance improvements.
