ID 577631 - Using a USD file that contains a <UDIM> texture that does not resolve to a valid file causes warning messages when rendering

Follow

Problem summary
If a USD file contains a <UDIM> texture that does not resolve to a valid file, Katana will not populate the filename attribute and it will cause warnings messages to appear when rendering.
 
Customer reported version
Katana.n_a
 
Customer reported platform
n_a_linux
 
Steps to reproduce
 
  1. Open the attached Katana scene or create a basic Katana scene that has a USD file that uses a <UDIM> texture.
     
  2. Initiate a render.
     
Expected behaviour
Katana should not error, and populate the attribute with the file path.
 
Actual behaviour
Currently, if a USD file uses a file path that uses <UDIM> texture, it will generate a Warning message: No resolved path for UDIM texture @./File/Path/missing_texture.<UDIM>.tx@. It will also not populate the relevant attribute.
 
Workaround
Unknown.
