Configure mesh LOD

To configure LOD, you must have a GameObject with a LOD GroupA component to manage level of detail (LOD) for GameObjects. More info
See in Glossary component. The LOD Group component provides controls to define how LOD behaves on this GameObject, and references the GameObjects that Unity shows or hides for each LOD level. See LOD Group for details on the properties in this component.

You can set up LOD in Unity two ways:

• You can configure LOD levels in your external 3D modeling application, and Unity can automatically create and configure the required GameObjects and components for you. See Importing LOD Meshes for details on the correct configuration.
• You can manually create a GameObject with a LOD Group component, and configure the LOD levels manually.

Configure LOD levels

To manually configure the distance from the camera at which Unity displays each LOD level, use the LOD Group component’s selection bar.

The LOD Group component accepts a maximum of eight LOD levels. LOD 0 is the closest to the Camera, and therefore the most detailed LOD level.

Configure project-wide LOD settings

In the Quality settings window, you can configure LOD settings that affect all GameObjects in your Project.

There are two LOD settings you can configure:

• Maximum LOD Level: Exclude meshes above a specified LOD level from your build.
• LOD Bias: Determine whether to favor higher or lower LOD levels at threshold distances.
