# Debug Mode options overlay reference

> Configure the Debug Draw mode options.

The Debug Draw Mode overlay has the following options that help you understand your graphics and lighting better. These controls only affect the Editor view during development and have no effect on the built game.

To open the Debug Mode options overlay, select the Debug Mode icon in the Draw Modes overlay. For more information, refer to [Draw Modes overlay reference](/engine/6000.3/manual/working-with-scenes/scenes-manage-gameobjects/overlays/reference/draw-modes.md).

The transparent colors accumulate, making it easy to spot places where one object is drawn over another.**Mipmaps** — Show ideal texture sizes using a color code:Red indicates that the texture is larger than necessary (at the current distance and resolution)Blue indicates that the texture might be larger. The ideal texture sizes depend on the resolution at which your application will run and how close the Camera can get to particular surfaces.**Texture Mipmap Streaming** — Tint GameObjects green, red, or blue, depending on their status in the [Texture Mipmap Streaming](/engine/6000.3/manual/materials-and-shaders/textures/texture-loading/texture-streaming.md) system. For more information, see documentation on [Analyze mipmap streaming](/engine/6000.3/manual/materials-and-shaders/textures/texture-loading/texture-streaming/analyze.md).**Sprite Mask** — Sprite Masks are used to either hide or reveal parts of a Sprite or group of Sprites. For more information, refer to [Sprite Masks](/engine/6000.3/manual/unity2d/sprite/mask.md). |
