Chaos Rings Omega (CRO-U): HD models.

  export/  the game writes its models here as glTF 2.0 (.glb): run it with --export-models
  hd/      the replacements it draws instead: <name>.glb (or .gltf), edited in Blender and the like,
           keeping the armature (bones node_<n>...) and the material names (cr_mat_<n>...)

With HD Models on (it is by default) a replacement here is drawn in place of the original.
Personal use only: they are made from the game's models. The README's "HD models".
