It would be great if we could export just a single file from the mesh editor and have the uploader recognize the various _PHYS and _LODn models in there. This simplifies the export process.
  1. In a first parse of the file, ignore all objects having the postfix _PHYS and _LODn except for what corresponds to the "High" LOD.
  2. In following parses of the file, look for objects in the first parse that has matching names with the relevant postfixes (_PHYS, _LODn)
  3. Search for the still missing corresponding models for _PHYS and _LODn in other files in the same folder, like is already done today.
