Default
Default is the most common Texture type used for all Textures. It provides access to most of the properties for Texture importing. With this Texture type, you can also change the Texture Shape property to define the Texture Shape.
When you choose the Default Texture type, the following properties are available (click the links for detailed information on each property):
| Property: | Function: |
|---|---|
| sRGB (Color Texture) | Enable this property to specify that the Texture is stored in gamma space. More info. |
| Alpha Source | Specify how the alpha channel of the Texture is generated. More info. |
| Alpha is Transparency | Enable this property to dilate the color and avoid filtering artifacts on the edges if the alpha channel you specify is Transparency. More info. |
| Remove Matte (PSD) | Enable special processing for Photoshop files that use transparency (blending color pixels with white). More info |
| Ignore PNG file gamma | Enable this property to ignore the Gamma attribute in PNG files. More info. |
| Non Power of 2 | If the Texture has a non-power of two (NPOT) dimension size, this defines a scaling behavior at import time. More info. |
| Read/Write Enabled | Enable this to access the Texture data from scripts A piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info See in Glossary using Texture2D.SetPixels, Texture2D.GetPixels and other Texture2D methods. More info. |
| Virtual Texture Only | Enable this texture to use it solely in combination with a Texture Stack for Virtual Texturing. More info. |
| Streaming Mip Maps | Enable this checkbox to use Mipmap Streaming on this Texture. More info. |
| Generate Mip Maps | Check this box to enable mipmap generation. More info. This property is enabled by default. |
| Wrap Mode | Select how the Texture behaves when tiled. More info. |
| Filter Mode | Select how the Texture is filtered when it gets stretched by 3D transformations. More info. |
| Aniso Level | Increases Texture quality when viewing the Texture at a steep angle. More info. |
In addition, you can use the Platform-specific overrides panel to set default options and their overrides for a specific platforms.
Normal map
Select Normal map A type of Bump Map texture that allows you to add surface detail such as bumps, grooves, and scratches to a model which catch the light as if they are represented by real geometry. More info
See in Glossary to turn the color channels into a format suitable for real-time normal mapping. With this Texture type, you can also change the Texture Shape property to define the Texture Shape.
When you choose the Normal map Texture type, you can set the following additional properties:
| Property: | Function: | |
|---|---|---|
| Create from Grayscale | Enable this property to create the Normal Map from a grayscale heightmap A greyscale Texture that stores height data for an object. Each pixel stores the height difference perpendicular to the face that pixel represents. See in Glossary . When enabled, the Bumpiness and Filtering options become available. This option is disabled by default. | |
| Bumpiness | Control the amount of bumpiness. A low bumpiness value means that even sharp contrast in the heightmap is translated to gentle angles and bumps. A high value creates exaggerated bumps and very high-contrast lighting responses to the bumps. This option is only visible if Create from Grayscale is checked. | |
| Filtering | Determine how the bumpiness is calculated: - Smooth generates Normal Maps with standard (forward differences) algorithms. | |
| Ignore PNG file gamma | Enable this property to ignore the Gamma attribute in PNG files. More info. | |
| Non Power of 2 | If the Texture has a non-power of two (NPOT) dimension size, this defines a scaling behavior at import time. More info. | |
| Read/Write Enabled | Enable this to access the Texture data from scripts using Texture2D.SetPixels, Texture2D.GetPixels and other Texture2D methods. More info. | |
| Virtual Texture Only | Enable this texture to use it solely in combination with a Texture Stack for Virtual Texturing. More info. | |
| Streaming Mip Maps | Enable this checkbox to use Mipmap Streaming on this Texture. More info. | |
| Generate Mip Maps | Check this box to enable mipmap generation. More info. This property is enabled by default. | |
| Wrap Mode | Select how the Texture behaves when tiled. More info. | |
| Filter Mode | Select how the Texture is filtered when it gets stretched by 3D transformations. More info. | |
| Aniso Level | Increases Texture quality when viewing the Texture at a steep angle. More info. | |
In addition, you can use the Platform-specific overrides panel to set default options and their overrides for a specific platforms.

Sprite (2D and UI)
Select Sprite (2D and UI) if you are using the Texture in a 2D game as a SpriteA 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. More info
See in Glossary . The Texture Shape property is always set to 2D for this Texture Type. For more information, see the documentation on Texture Shapes.
When you choose the Sprite (2D and UI) Texture type, you can set the following additional properties:
| Property: | Function: | |
|---|---|---|
| Sprite Mode | Specify how to extract the Sprite graphic from the image. The default for this option is Single. | |
| Single | Use the Sprite image as is. You can clip and edit the image in the Sprite Editor to refine it further, but Unity treats the Sprite generated from the imported Texture as a single Asset. | |
| Multiple | Choose this value if your image has several elements in the same image. You can then define the location of the elements in the Sprite Editor so that Unity knows how to split the image into different sub-Assets. For example, you can create animation frames from a single sheet with multiple poses, create TilesA simple class that allows a sprite to be rendered on a Tilemap. More info See in Glossary from a single Tilesheet, or create the different parts of a character. | |
| Polygon | Choose this value to clip the Sprite Texture according to the Mesh The main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info See in Glossary defined in the Sprite Editor's Sprite Custom Outline. | |
| Packing Tag | Specify (by name) the Sprite Atlas A texture that is composed of several smaller textures. Also referred to as a texture atlas, image sprite, sprite sheet or packed texture. More info See in Glossary which you want to pack this Texture into. This property is visible only when you enable the Legacy Sprite Packer in your Project. | |
| Pixels Per Unit | The number of pixels The smallest unit in a computer image. Pixel size depends on your screen resolution. Pixel lighting is calculated at every screen pixel. More info See in Glossary of width/height in the Sprite image that correspond to one distance unit in world space. | |
| Mesh Type | Define the Mesh type for the Sprite you want Unity to generate. The default for this option is Tight. Note: This property is only available for the Single and Multiple Sprite Modes. | |
| Full Rect | Choose this value to create a quad A primitive object that resembles a plane but its edges are only one unit long, it uses only 4 vertices, and the surface is oriented in the XY plane of the local coordinate space. More info See in Glossary (four-sided polygon) to map the Sprite onto. | |
| Tight | Choose this value to generate a Mesh based on pixel alpha value. The Mesh that Unity generates generally follows the shape of the Sprite. Note: Any Sprite that is smaller than 32x32 uses Full Rect, even when Tight is specified. | |
| Extrude Edges A Texture property that enables you to define how much area to leave around a sprite in a generated mesh. See in Glossary | Use the slider to determine how much area to leave around the Sprite in the generated Mesh. | |
| Pivot | The location in the image where the Sprite's local coordinate system originates. Choose one of the pre-set options, or select Custom to set your own Pivot location in X and Y. Note: This property is only available for the Single Sprite Mode. | |
| Generate Physics Shape | When this is enabled and you have not defined a Custom Physics Shape for this Sprite, Unity generates a default Physics Shape from the outline of the Sprite. Note: This property is only available for the Single and Multiple Sprite Modes. | |
| Sprite Editor | Click this button to define how you want Unity to separate the elements on an image with Multiple elements (to create sub-Assets) or refine the shape, size, and pivot position of a Polygon shape. Note: You need to install the 2D Sprite package in order to use the Sprite Editor. For information about how to find and install packages in the Unity Package Manager, see Finding packages and Installing from the registry. | |

In addition, you can use the Platform-specific overrides panel to set default options and their overrides for a specific platforms.
Cookie
Select Cookie to set your Texture up with the basic parameters used for cookies in the Built-in Render Pipeline. With this Texture type, Unity updates the Texture Shapes property automatically based on the selected Light Type:
- Directional and Spotlight cookies are always 2D Textures (the 2D shape type).
- Point Light cookies must be cubemaps A collection of six square textures that can represent the reflections in an environment or the skybox drawn behind your geometry. The six squares form the faces of an imaginary cube that surrounds an object; each face represents the view along the directions of the world axes (up, down, left, right, forward and back). More info
See in Glossary (the Cube shape type).
When you choose the Cookie Texture type, you can set the following additional properties:
| Property: | Function: | |
|---|---|---|
| Light Type | Define the type of Light that the cookie is applied to. Note that you must create your source texture with an appropriate layout: cookies for Point Lights must be laid out as cubemaps, and cookies for Directional Lights and Spot Lights must be laid out as regular 2D Textures. If you apply a cookie to a Directional Light, you can use a cookie configured for a Directional Light, or a cookie configured for a Spot Light. A Directional Light using a cookie configured for a Directional Light repeats the cookie in a tiled pattern all over the scene. A Directional Light using a cookie configured for a Spot Light projects the cookie just once in the direct path of the "beam" of the light. This is the only case where the position of a Directional Light is important. | |
| Spotlight | With this type of Light, you want the edges of your Cookie Texture to be solid black to get the proper effect, so Unity sets the Wrap Mode to Clamp by default. | |
| Directional | With this type of Light, this Texture tiles, so Unity sets the Wrap Mode to Repeat by default. | |
| Point | When you choose this type of Light, you can also customize the Cube shape-specific | |
| Alpha Source | Specify how the alpha channel of the Texture is generated. More info. | |
| Alpha is Transparency | Enable this property to dilate the color and avoid filtering artifacts on the edges if the alpha channel you specify is Transparency. More info. | |

Lightmap
Select Lightmap A pre-rendered texture that contains the effects of light sources on static objects in the scene. Lightmaps are overlaid on top of scene geometry to create the effect of lighting. More info
See in Glossary if you are using the Texture as a Lightmap. This option enables encoding into a specific format (RGBM or dLDR, depending on the platform) and a post-processing A process that improves product visuals by applying filters and effects before the image appears on screen. You can use post-processing effects to simulate physical camera and film properties, for example Bloom and Depth of Field. More info post processing, postprocessing, postprocess
