Property		Function
3D Icons		The 3D Icons checkbox controls whether component icons (such as those for Lights and Cameras) are drawn by the Editor in 3D in the Scene view. When the 3D Icons checkbox is ticked, component icons are scaled by the Editor according to their distance from the Camera, and obscured by GameObjects in the Scene. Use the slider to control their apparent overall size. When the 3D Icons checkbox is not ticked, component icons are drawn at a fixed size, and are always drawn on top of any GameObjects in the Scene view. See Gizmos and Icons, below, for images and further information.
Fade Gizmos		Fade out and stop rendering gizmos that are small on screen.
Selection Outline		Check Selection Outline to display selected GameObjects with a colored outline, and their children with a different colored outline. By default, Unity highlights the selected GameObject in orange, and child GameObjects in blue. NOTE: This option is only available in the Scene view Gizmos menu; you cannot enable it in the Game view Gizmos menu. See Selection Outline and Selection Wire, below, for images and further information.
Selection Wire		Check Selection Wire to show the selected GameObjects with their wireframe Mesh visible. To change the colour of the Selection Wire, go to Edit > Preferences (macOS: Unity > Settings) in the main menu, select Colors, and alter the Selected Wireframe setting. This option is only available in the Scene view Gizmos menu; you cannot enable it in the Game view Gizmos menu. See Selection Outline and Selection Wire, below, for images and further information.
Light Probe Visualization		Select which Light ProbesLight probes store information about how light passes through space in your scene. A collection of light probes arranged within a given space can improve lighting on moving objects and static LOD scenery within that space. More info See in Glossary to display in the Scene view. The default value is Only Probes Used By Selection.
	Only Probes Used By Selection	Display only Light Probes that affect the current selection.
	All Probes No Cells	Display all Light Probes.
	All Probes With Cells	Display all Light Probes, and the tetrahedrons that Unity uses for interpolation of Light Probe data.
	None	Display no Light Probes.
Display Weights		When enabled, Unity draws a line from the Light Probe used for the active selection to the positions on the tetrahedra used for interpolation. This is a way to debug probe interpolation and placement problems.
Display Occlusion		When enabled, Unity displays occlusion data for Light Probes if the Lighting Mode is set to ShadowmaskA Texture that shares the same UV layout and resolution with its corresponding lightmap. More info See in Glossary.
Highlight Invalid Cells		Enable to highlight tetrahedrons that Unity can’t use for indirect lighting. For example if the Light Probes are very close together.
Recently Changed		Controls the visibility of the icons and gizmos for components and scripts that you modified recently. This section appears the first time you change one or more items, and updates after subsequent changes. For more information, see Built-in components, scripts, and recently changed items, below.
Scripts		Controls the visibility of the icons and gizmos for scripts in the Scene. This section appears only when your Scene uses scripts that meet specific criteria. See Built-in components, scripts, and recently changed items, below, for further information.
Built-in Components		Controls the visibility of the icons and gizmos for all component types that have an icon or gizmo. See Built-in components, scripts, and recently changed items, below, for further information.

Gizmos and Icons

Gizmos

Gizmos are graphics associated with GameObjects in the Scene. Some Gizmos are only drawn when the GameObjectThe 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 is selected, while other Gizmos are drawn by the Editor regardless of which GameObjects are selected. They are usually wireframes, drawn with code rather than bitmap graphics, and can be interactive. The CameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info
See in Glossary Gizmo and Light direction Gizmo (shown below) are both examples of built-in Gizmos; you can also create your own Gizmos using script. See documentation on Understanding Frustum for more information about the Camera.

Some Gizmos are passive graphical overlays, shown for reference (such as the Light direction Gizmo, which shows the direction of the light). Other Gizmos are interactive, such as the AudioSource spherical range Gizmo, which you can click and drag to adjust the maximum range of the AudioSource.

The Move, Scale, Rotate and Transform tools are also interactive Gizmos. See documentation on Positioning GameObjects to learn more about these tools.

See the Script Reference page for the OnDrawGizmos function for further information about implementing custom Gizmos in your scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary.

Icons

You can display icons in the Game view or Scene view. They are flat, billboard-style overlays which you can use to clearly indicate a GameObject’s position while you work on your game. The Camera icon and Light icon are examples of built-in icons; you can also assign your own to GameObjects or individual scripts (see documentation on Assigning Icons to learn how to do this).

Selection Outline and Selection Wire

Selection Outline

When Selection Outline is enabled, an outline appears around selected GameObjects and their child GameObjects. By default, Unity outlines selected GameObjects in orange, and child GameObjects in blue. You can change these colors in the Unity preferences (see Selection Colors, below).

When you select a GameObject, Unity outlines all of its child GameObjects (and their child GameObjects, and so on), but does not outline parent GameObjects (or their parent GameObjects, and so on).

If selected GameObjects extend beyond the edges of the Scene view, the selection outline runs along the edge of the window:

Selection Wire

When Selection Wire is enabled, then when you select a GameObject in the Scene view or Hierarchy window, the wireframe MeshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info
See in Glossary for that GameObject is made visible in the Scene view:

Selection colors

You can set custom colors for selection wireframes.

1. Go to Unity > Preferences (macOS) or Edit > Preferences (Windows) to open the Preferences editor.
2. On the colors tab, change one or more of the following colors:
   • Selected Children Outline: outline color for selected GameObjects’ children.
   • Selected Outline: outline color for selected GameObjects.
   • Wireframe Selected: outline color for selected GameObjects’ wireframes.

Built-in components, scripts, and recently changed items

Use the list in the Gizmos menu to control the visibility of icons and gizmos for various components. The list is divided into sections:

Recently Changed

The Recently Changed section controls the visibility of the icons and gizmos for items that you’ve modified recently. It appears the first time you change one or more items. Unity updates the list after subsequent changes.

Scripts

The Scripts section controls the visibility of the icons and gizmos for scripts that:

• Have an icon assigned to them (see documentation on Assigning Icons).

• Implement the OnDrawGizmos function.

• Implement the OnDrawGizmosSelected function.

This section appears when your Scene contains one or more scripts that meet the above criteria.

Built-in Components

The Built-in Components section controls the visibility of the icons and gizmos for all component types that have an icon or gizmo.

Built-in component types that do not have an icon or gizmo shown in the Scene view (for example, Rigidbody) are not listed here.

Toggling icon visibility

The icon column shows or hides the icons for each component type. Full-color icons are displayed in the main Scene view window, faded icons are not.

To toggle an icon’s visibility in the Scene view, click any icon in the icon column.

Note: If an item in the list has a gizmo but no icon, the icon column for that item is empty.

Changing script icons

Scripts with custom icons show a small drop-down menu arrow in the icon column. To change a custom icon, click the arrow to open the Select Icon menu.

Toggling gizmo visibility

To control whether the Editor draws gizmo graphics for a particular component type (for example, a Collider’s wireframe gizmo or a Camera’s view frustum gizmo) or script, use the checkboxes in the Gizmo column.

• When a checkbox is checked, the Editor draws gizmos for that component type.

• When a checkbox is cleared, the Editor does not draw gizmos for that component type.

Note: If an item in the list has an icon but no gizmo, the Gizmo column for that item is empty.

To toggle gizmo visibility for an entire section (all Built-in Components, all Scripts, and so on), use the checkboxes next to the section names.

The Built-in Components checkbox toggles gizmo visibility for every type of component listed in that section

When the checkbox is toggled on, gizmo visibility is toggled on for one or more item types in the section.
