# Render to a 2D texture array

> Create a render texture to render to a 2D texture array.

To render to a 2D texture array, create a [render texture](/engine/6000.6/manual/materials-and-shaders/textures/render-texture.md) and set the **Dimension** property to **2D Array**.

If you use the [`Graphics.SetRenderTarget`](/engine/6000.6/script-reference/unityengine/graphics/setrendertarget.md) API, set the `depthSlice` parameter to the slice you want to render to.

If the platform supports geometry shaders, use a geometry shader to render to individual slices, or set `depthSlice` to `-1` to render to all the slices.
