Extra data is added to materials when extracting and reimporting .usd, .usda, .usdc & .usdz files with USD Exporter and USD Importer
How to reproduce:
- Open the project "IN-66095"
- Open the “SampleScene” scene
- Select “Root“ GameObject from the Hierarchy window, open USD → “Export Selected With Children“ and save the file
- Drag the saved file into the Project window and select it, in the Inspector window enable “Import” and press “Apply”
- In the Project window, click on one of the imported materials and observe the Inspector window
Expected result: Material data is the same as before importing it
Actual result: Material has extra data added about it (Displacement, ClearCoatMask, etc.)
