However, when working in a team, you may find that other users might keep making changes to Assets, all of which must be imported. This arrangement is designed to make the workflow as efficient and flexible as possible for an individual user. The imported data from the file is subsequently stored by Unity in an internal format. fbx file is modified, Unity detects the change and automatically re-imports it. Unity has a completely automatic Asset pipeline. If you use Asset Import Pipeline version 2, use Unity Accelerator instead. Important: Cache Server only supports Asset Import Pipeline version 1.
