# Shadowmask texture Import Settings window reference

> Explore the settings for a shadowmask texture.

The Editor texture type formats the texture asset so that it can be used as a [shadowmask](/engine/6000.0/manual/lighting-overview/lighting-light-sources/components/configuring/lighting-mode/lighting-mode.md#shadowmask). 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).
