# Directional lightmap texture Import Settings window reference

> Explore the settings for a directional lightmap texture.

The **Directional Lightmap** texture type formats the texture asset so it's suitable to use as a directional [Lightmap](/engine/6000.0/manual/lighting-overview/lighting-reference/class-lightmap-parameters.md). Unity locks **Texture Shape** to **2D** for this texture type. For more information, refer to [Texture Shape](/engine/6000.0/manual/materials-and-shaders/textures/textures-reference/class-texture-importer.md#textureshape).

| Property | Description |

In addition, you can use the [Platform-specific overrides](/engine/6000.0/manual/materials-and-shaders/textures/textures-reference/class-texture-importer.md.md#platform) panel to set default options and overrides for specific platforms.
