Delete Unused Materials was created based on a request from the Omniverse forums.
It also provided me a chance to learning Python, USD, and Kit APIs/workflows.
This tool was created so users can Delete Unused Materials from the scene. When new materials are applied to an object the old one remains in the scene. The tool skips materials in References and Payloads as they can only be deleted in the original file.
After installation the dialog can be opened by Right-Clicking in the Stage > Delete Unused Materials.
To add this extension to your Omniverse app:
- Go into: Extension Manager -> Gear Icon -> Extension Search Path
- Add this as a search path:
git://github.com/ericcraft-mh/meadhunt-utility-materials-deleteunused.git?branch=main&dir=exts
- Custom Glyph in context menu.
- Confirmation dialog with ability to deselect materials you don't want to remove.
If app folder link doesn't exist or broken it can be created again. For better developer experience it is recommended to create a folder link named app to the Omniverse Kit app installed from Omniverse Launcher. Convenience script to use is included.
Run:
> link_app.bat
If successful you should see app folder link in the root of this repo.
If multiple Omniverse apps is installed script will select recommended one. Or you can explicitly pass an app:
> link_app.bat --app create
You can also just pass a path to create link to:
> link_app.bat --path "C:/Users/bob/AppData/Local/ov/pkg/create-2021.3.4"
