| 17    | Equipment      | AnyRPG          | Set anything attached to the player to this layer to prevent it from interfering with ground detection or projectors.                                                                                                                    |
| 18    | FireLayer      | Package         | Unused. This was probably from an import of a VFX package.                                                                                                                                                                               |
| 19    | PlayerPreview  | AnyRPG          | Used by the load game screen to allow the camera to ignore anything that is not a player preview.                                                                                                                                        |

| 23    | UnitPreview    | AnyRPG          | Unit previews such as unit spawn control panelswill place their targets on this layer so other cameras don't render them.                                                                                                                |
| 24    | PetPreview     | AnyRPG          | Pet previews such as pet journals will place their targets on this layer so other cameras don't render them.                                                                                                                             |
| 25    | Interactable   | AnyRPG          | Used to render non character units in Unit frames without rendering the environment.                                                                                                                                                     |
