The Tags and Layers settings (main menu: Edit > Project SettingsA broad collection of settings which allow you to configure how Physics, Audio, Networking, Graphics, Input and many other areas of your project behave. More info
See in Glossary, then select the Tags and Layers category) allows you to set up TagsA reference word which you can assign to one or more GameObjects to help you identify GameObjects for scripting purposes. For example, you might define and “Edible” Tag for any item the player can eat in your game. More info
See in Glossary, Sorting Layers and LayersLayers in Unity can be used to selectively opt groups of GameObjects in or out of certain processes or calculations. This includes camera rendering, lighting, physics collisions, or custom calculations in your own code. More info
See in Glossary.
Tags are marker values that you can use to identify objects in your Project (see documentation on Tags for further details). To add a new Tag, click the plus button (+) at the bottom-right of the list, and name your new Tag.
Note that once you have named a Tag, you cannot rename it. To remove a Tag, click on it and then click the minus (-) button at the bottom-right of the list.
Sorting Layers are used in conjunction with SpriteA 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. More info
See in Glossary graphics in the 2D system. Sorting refers to the overlay order of different Sprites.
To add and remove Sorting Layers, use the plus and minus (+/-) buttons at the bottom-right of the list. To change their order, drag the handle at the left-hand side of each Layer item.
Use Layers throughout the Unity Editor as a way to create groups of objects that share particular characteristics (see documentation on Layers for further details). Use Layers primarily to restrict operations such as raycasting or rendering, so that they are only applied to the relevant groups of objects. Layers marked as Builtin Layer are default layers used by Unity, which you cannot edit. You can customise layers marked as User Layer.
To customise User Layers, type a custom name into the text field for each one you wish to use. Note that you can’t add to the number of Layers but, unlike Tags, you can rename Layers.
If your project uses the Universal Render PipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info
See in Glossary (URP) or the High Definition Render Pipeline (HDRP), this section lists the names of Rendering Layers. Use Rendering Layers to configure which lights or decals affect which GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary. Refer to the following for more information:
The Built-In Rendering Pipeline doesn’t support Rendering Layers.
