ID 608726 - Loading a USD file with multiple geometries where some don't have UVs means Mari won't load geometries without UVs, and the rest are forced to Ptex

Problem summary
When loading a USD file with multiple geometries, Mari ignores those without UV maps. Also, if the Mapping Scheme is set to UV if available, empty otherwise, the Ptex Window appears once Create New Project is pressed.

Steps to reproduce

 

1. Launch Mari.

    

2. Select File -> New.

6. Select Create New Project.

    

7. Select OK in the upcoming Ptex Window.

    

8. Click Ok on the Warning Window.

 
Expected behaviour
Mari should be able to load geometries without UV data in a USD file without being forced to use Ptex.
 
Actual behaviour
When Mari loads a USD file with multiple geometries, any geometry without UVs is ignored, and the rest is forced to Ptex.
 
Workaround
Make sure all the geometries have UV data.
