# lightmapMaxSize

> The maximum size in pixels of an individual lightmap texture. (Editor only).

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public int lightmapMaxSize { get; set; }
```

### Remarks

The default value is 1024. Values are squared, so a value of 1024 results in a maximum resolution of 1024 x 1024. Smaller lightmaps might also be generated instead. This happens if it is possible to fit the required UVs into a smaller texture.

This setting affects lightmaps generated by the Baked Global Illumination system.

When Unity serializes this `LightingSettings` object as a [Lighting Settings Asset](/engine/6000.7/manual/lighting-overview/lighting-reference/class-lighting-settings.md), this property corresponds to the **Max Lightmap Size** property in the Lighting Settings Asset Inspector.
