# Tile Set Importer Inspector window reference > Explore the settings you can use to configure a tileset, which automatically creates tiles from a texture and its sprites. Explore the settings you can use to configure a tileset, which automatically creates tiles from a texture and its sprites. For more information, refer to [Create a tile palette](/engine/6000.5/manual/unity2d/tilemaps/create-tile-palette/assets.md). | **Property** | **Description** | | ---------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Open Tile Palette Window** | Opens the [Tile Palette window](/engine/6000.5/manual/unity2d/tilemaps/create-tile-palette/tile-palette-editor-reference.md) so you can paint tiles with the tile set. | ## Texture Sources The properties in this section let you select the texture you want to create tiles from. | **Property** | **Description** | | ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Texture** | Sets the texture Unity creates tiles from. | | **Tile Template** | Sets the optional tile template that determines how Unity creates tiles from the texture. If you don't set a tile template, Unity creates a tile for each sprite in the texture. For more information, refer to [Customize how Unity creates tiles from a texture](/engine/6000.5/manual/unity2d/tilemaps/create-tile-palette/tile-template-asset.md). | | **Add** (**+**) | Adds a new element with a **Texture** and a **Tile Template** field. | | **Remove** (**-**) | Removes the selected element, or removes the last element if no element is selected. | ## Palette Grid | **Property** | **Description** | | -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Cell Layout** | Sets the layout of the cells. The options are:**Rectangle**: Lays out the cells as a rectangular grid.**Hexagon**: Lays out the cells as a hexagonal grid.**Isometric**: Lays out the cells as an isometric grid.**Isometric Z as Y**: Lays out the cells as an isometric grid, where each tile has a z value that represents its 3D height. | | **Hexagon Layout** | Sets the type of the hexagonal grid. This option is available only if you set **Grid** to **Hexagon**. The options are:**Point Top**: Aligns the hexagons so they have a point at the top.**Flat Top**: Aligns the hexagons so they have a flat edge at the top. | | **Cell Sizing** | Sets the size of the cells in the tile palette. The options are:**Automatic**: Sets the cell size automatically based on the size of the tile at the bottom-left of the tile palette.**Manual**: Sets the cell size manually in units. | | **Transparency Sort Mode** | Sets the method Unity uses to calculate the depth of tiles for sorting. This property has transparency in its name because Unity renders 2D objects during the transparent render pass. For more information, refer to [Sort sprites](/engine/6000.5/manual/unity2d/sprite/sort-sprites/sort-sprites.md).The options are:**Default**: Sorts using **Perspective** or **Orthographic**, depending on the **Projection** property of the camera.**Perspective**: Calculates the depth of a tile as the distance between the tile and the center point of the camera. Use this option for isometric games.**Orthographic**: Calculates the depth of a tile as the distance between the tile and the camera plane. Use this option for top-down games.**Custom Axis**: Uses a custom axis to calculate depth. | | **Transparency Sort Axis** | Sets the x-axis, y-axis, and z-axis of the sorting axis if you set **Transparency Sort Mode** to **Custom Axis**. For example, a vertical axis (0, 1, 0) means higher GameObjects are further away, which is useful for top-down games. | ## Sprite Atlas Settings This section is available only if you enable **Create Atlas**. For more information, refer to [Packing sprites into atlas textures](/engine/6000.5/manual/unity2d/sprite/atlas.md). | **Property** | **Description** | | -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Create Atlas** | Creates a sprite atlas from the **Texture Sources**. | | **Type** | This property isn't available in this window. | | **Include in Build** | Enables Unity loading the sprite atlas and attaching it to your sprites when your project starts. Disable this property to load the sprite atlas yourself at runtime instead. For more information, refer to [Load sprite atlases manually at runtime](/engine/6000.5/manual/unity2d/sprite/atlas/load-sprite-atlas-spriteatlasmanageratlasrequested.md). | ### Packing These properties are available only if you set **Type** to **Master**. | **Property** | **Description** | | ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Allow Rotation** | Rotates sprites in the sprite atlas texture to find a better fit. Disable this property if you pack [Canvas UI](/engine/6000.5/manual/uicanvas.md) elements, to avoid UI elements rotating. | | **Tight Packing** | Packs each sprite based on its mesh shape from the Custom Outline tab of the Sprite Editor window, instead of the default rectangle. | | **Alpha Dilation** | Expands the colors of the edge of the sprite into adjacent transparent pixels, to prevent visible edges. | | **Padding** | Sets how many pixels Unity uses between individual sprites, to prevent pixels from one sprite appearing in an adjacent sprite. The default value is 4. | ### Texture | **Property** | **Description** | | --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Read/Write** | Allows you to access the data of the sprite atlas in C# scripts using methods such as [Texture2D.SetPixels](/engine/6000.5/script-reference/unityengine/texture2d/setpixels.md). If you enable this property, Unity creates a duplicate copy of the texture data, which can reduce performance. This property only has an effect if the sprite atlas is uncompressed or uses DXT compression. | | **Generate Mip Maps** | Creates mipmap levels for the sprite atlas texture. For more information, refer to [Mipmaps](/engine/6000.5/manual/materials-and-shaders/textures/textures-getting-started/texture-mipmaps-introduction.md). | | **sRGB** | Stores the sprite atlas colors in gamma space. For more information, refer to [Color spaces](/engine/6000.5/manual/materials-and-shaders/graphics-color/color-spaces.md). | | **Filter Mode** | Specifies how Unity filters the sprite atlas when it stretches. The options are:**Point**: Uses the nearest pixel. This makes the sprite atlas appear pixelated.**Bilinear**: Uses a weighted average of the four nearest texels. This makes the sprite atlas appear blurry when you magnify it.**Trilinear**: Uses a weighted average of the two nearest mipmap levels, which Unity filters using bilinear filtering. This creates a soft transition between mipmap levels, but the sprite atlas is slightly more blurry. | | **Aniso Level** | Sets the anisotropic filtering level of the sprite atlas. This increases texture quality when you view the sprite atlas at a steep angle. This property is available only if you enable **Generate Mip Maps** and set **Filter Mode** to **Bilinear** or **Trilinear**. | ## Show Platform Settings The properties in this section set the size and format of the sprite atlas texture. | **Property** | **Description** | | ------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Show Platform Settings For** | Selects which texture the properties in the **Default** tab and the platform-specific tabs display. Select either the main texture of the sprite atlas, or a secondary texture. For more information about secondary textures, refer to [Add normal map and mask map textures to a sprite](/engine/6000.5/manual/unity2d/2d-urp/2d-index/secondary-textures.md). | ### Default tab The **Default** tab lets you set the final size and format of the sprite atlas texture on all platforms. | **Property** | **Description** | | -------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Max Texture Size** | Sets the maximum dimensions of the sprite atlas in pixels. If any of the sprites or textures are larger than the **Max Texture Size**, Unity ignores the **Max Texture Size** setting and uses the minimum size that contains the sprites and textures at their original dimensions.**Important**: Don't use **Max Texture Size** values smaller than 0.25 for [variant sprite atlases](/engine/6000.5/manual/unity2d/sprite/atlas/master-variant-sprite-atlases.md), otherwise Unity compresses the sprites and textures twice. | | **Format** | Sets the number of channels and the data type of the sprite atlas, except for platforms you override in the platform-specific override tabs. The default is **Automatic**, where Unity selects a value based on the number of channels in the sprites, and the **Compression** setting. For more information, refer to [Default formats](/engine/6000.5/manual/materials-and-shaders/textures/textures-reference/class-texture-importer/type-specific.md#default-formats). | | **Compression** | Sets the compression of the sprite atlas. Unity uses this setting to select an appropriate texture format. This setting is only available if you set **Format** to **Automatic**. For more information, refer to [Default formats](/engine/6000.5/manual/materials-and-shaders/textures/textures-reference/class-texture-importer/type-specific.md#default-formats). The options are:**None**: Don't compress the sprite atlas.**Low Quality**: Compresses the sprite atlas using a low-quality texture format. The compressed texture might use less memory than **Normal Quality**.**Normal Quality**: Compresses the sprite atlas using a standard texture format.**High Quality**: Compresses the sprite atlas using a high-quality texture format. The compressed texture might use more memory than **Normal Quality**. | | **Use Crunch Compression** | Compresses the sprite atlas using the Crunch compression library, which helps Unity use the lowest possible amount of space. This setting is only available if you set **Format** to **Automatic**. Unity decompresses the sprite atlas to DXT or ETC format on the CPU, then uploads it to the GPU at runtime. If you enable this setting, textures might take a long time to compress, but decompression at runtime is fast. | | **Compressor Quality** | Sets the image quality of the compressed texture, if you enable **Use Crunch Compression**. A higher value might use more memory and increase compression time. | ### Platform-specific overrides tabs The platform-specific override tabs let you override the settings in the **Default** tab for specific platforms. For more information about build platforms, refer to [Build Profiles window reference](/engine/6000.5/manual/building-and-publishing/build-settings/build-profiles-reference.md). | **Property** | **Description** | | ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Max Texture Size** | Sets the maximum dimensions of the imported texture in pixels. If any of the sprites or textures are larger than the **Max Texture Size**, Unity ignores the **Max Texture Size** setting and uses the minimum size that contains the sprites and textures at their original dimensions.**Important**: Don't use **Max Texture Size** values smaller than 0.25 for [variant sprite atlases](/engine/6000.5/manual/unity2d/sprite/atlas/master-variant-sprite-atlases.md), otherwise Unity compresses the sprites and textures twice. | | **Format** | Sets the sprite atlas format. The available texture formats depend on the platform. Unity selects the default format based on the platform and the settings in the **Default** tab. For more information, refer to [Default formats](/engine/6000.5/manual/materials-and-shaders/textures/textures-reference/class-texture-importer/type-specific.md#default-formats). | | **Compressor quality** | Sets the quality of the sprite atlas that compression produces. This setting isn't available for all texture formats. | ## Additional resources * [Create a tile palette](/engine/6000.5/manual/unity2d/tilemaps/create-tile-palette/assets.md) * [Customize how Unity creates tiles from a texture](/engine/6000.5/manual/unity2d/tilemaps/create-tile-palette/tile-template-asset.md)
