Editor crashes in CalculateSurfaceArea when using auto-generated UVs

Progressive Lightmapper


How to reproduce:
1. Open
2. Open the Assets/UsdUnitySDK/Examples/ImportMesh/ImportMesh Scene
3. Click on Kitchen_set GameObject
4. Mark as Static, including children

Reproducible with: 2018.1.9f2, 2018.2.16f1, 2018.3.0b9, 2019.1.0a8
Not reproducible with: 2017.4.15f1 and lower because of unsupported features

Expected results: GameObject is made Static

  1. Resolution Note (fix version 2018.3):

    The problem lies with the USD exporter that export corrupted meshes.
