This allows Godot to automatically compress meshes to save a lot of bandwidth. In general, this requires no interaction from the user and should result in no noticable quality loss. This scheme is not backwards compatible, so we have provided an upgrade mechanism, and a mesh versioning mechanism. Existing meshes can still be used as a result, but users can get a performance boost by reimporting assets.
