When opening the "Import Model" window for the first time, all settings are set to Pixyz default values.
All settings can be adjusted to user's requirement, and saved. Use the "Create" button to create an Import Settings asset.
When 'Create' is clicked, an asset will be created in the project Asset folder :
The Import settings asset can be renamed, copied (trough the Windows folder) and/or modified at your convenience.
The import settings asset can be drag and dropped into the import panel to be used for the next import process.
WARNING Unity saves changes made to serialized assets only when clicking 'Save Project'. Make sure you save your project before quitting Unity or changes you made to your import settings (or other serialized assets such as Rule Engine rules set) won't be save properly.
