Release Notes


In this viewer we've modified the importer to (optionally) improve debug output, perform name-based LOD association, and handle models with many materials.

Using these new features, models with more than 8 unique faces can be imported. Gone are the days of importing complicated meshes in pieces with "some assembly required". At import, these models are automatically split into pieces so that each satisfy the current face limits for a volume.

  • The same limitations on LODs and materials remain in place (e.g. your low LOD mesh materials must be a subset of the full LOD materials).
  • LODs and Physics reps can now be explicitly associated with a given mesh in the full LOD model using name-based matching.
  • By properly naming the meshes in your lower LOD meshes and physics reps, you can avoid issues with ordering of the meshes within your DCC tool and other material mismatching errors.
  • An ImporterDebug option has been added to the settings.xml file which, if enabled, causes more information to be output during import than you can shake a stick at. The extra output can be very helpful for diagnosing authoring errors (e.g. violating the material subset constraints mentioned above) and pinpoint what needs to be fixed in the source model for successful import.
