Texture Types

You can import different Texture types into the Unity Editor via the Texture Importer.

Below are the properties available to configure the various Texture types in Unity in the Texture Inspector window. Scroll down or select from the list below to find details of the Texture type you wish to learn about.

• Default
• Normal Map
• Editor GUI and Legacy
• Sprite (2D and UI)
• Cursor
• Cookie
• Lightmap
• Single Channel

Texture type: Default

Property:	Function:
Texture Type	Default is the most common setting used for all Textures. It provides access to most of the properties for Texture importing.
Texture Shape	Use this to define the shape of the Texture. See documentation on the Texture Importer for information on all Texture shapes.
sRGB (Color Texture)	Check this box to specify that the Texture is stored in gamma space. This should always be checked for non-HDR color Textures (such as Albedo and Specular Color). If the Texture stores information that has a specific meaning, and you need the exact values in the Shader (for example, the smoothness or the metalness), uncheck this box. This box is checked by default.
Alpha Source	Use this to specify how the alpha channel of the Texture is generated. This is set to None by default.
None	The imported Texture does not have an alpha channel, whether or not the input Texture has one.
Input Texture Alpha	This uses the alpha from the input Texture if a Texture is provided.
From Gray Scale	This generates the alpha from the mean (average) of the input Texture RGB values.
Alpha is Transparency	If the alpha channel you specify is Transparency, enable Alpha is Transparency to dilate the color and avoid filtering artifacts on the edges.
Advanced
Non Power of 2	If the Texture has a non-power of two (NPOT) dimension size, this defines a scaling behavior at import time. See documentation on Importing Textures for more information on non-power of two sizes. This is set to None by default.
None	Texture dimension size stays the same.
To nearest	The Texture is scaled to the nearest power-of-two dimension size at import time. For example, a 257x511 px Texture is scaled to 256x512 px. Note that PVRTC formats require Textures to be square (that is width equal to height), so the final dimension size is upscaled to 512x512 px.
To larger	The Texture is scaled to the power-of-two dimension size of the largest dimension size value at import time. For example, a 257x511 px Texture is scaled to 512x512 px.
To smaller	The Texture is scaled to the power-of-two dimension size of the smallest dimension size value at import time. For example, a 257x511 px Texture is scaled to 256x256 px.
Read/Write Enabled	Check this box to enable access to the Texture data from script functions (such as Texture2D.SetPixels, Texture2D.GetPixels and other Texture2D functions). Note that a copy of the Texture data is made, doubling the amount of memory required for Texture Assets, so only use this property if absolutely necessary. This is only valid for uncompressed and DXT compressed Textures; other types of compressed textures cannot be read from. This property is disabled by default.
Generate Mip Maps	Check this box to enable mipmap generation. Mipmaps are smaller versions of the Texture that get used when the Texture is very small on screen. See documentation on Importing Textures for more information on mipmaps.
Border Mip Maps	Check this box to avoid colors bleeding out to the edge of the lower MIP levels. Used for light cookies (see below). This box is unchecked by default.
Mip Map Filtering	There are two ways of mipmap filtering available for optimizing image quality. The default option is Box.
Box	This is the simplest way to fade out mipmaps. The MIP levels become smoother as they go down in dimension size.
Kaiser	A sharpening algorithm runs on the mipmaps as they go down in dimension size. Try this option if your Textures are too blurry in the distance. (The algorothm is of a Kaiser Window type - see Wikipedia for further information.)
Fadeout Mip Maps	Enable this to make the mipmaps fade to gray as the MIP levels progress. This is used for detail maps. The left-most scroll is the first MIP level to begin fading out. The right-most scroll defines the MIP level where the Texture is completely grayed out.
Wrap Mode	Select how the Texture behaves when tiled. The default option is Clamp.
Repeat	The Texture repeats itself in tiles.
Clamp	The Texture’s edges are stretched.
Filter Mode	Select how the Texture is filtered when it gets stretched by 3D transformations. The default option is Point (no filter).
Point (no filter)	The Texture appears blocky up close.
Bilinear	The Texture appears blurry up close.
Trilinear	Like Bilinear, but the Texture also blurs between the different MIP levels.
Aniso Level	Increases Texture quality when viewing the Texture at a steep angle. Good for floor and ground Textures. See documentation on Importing Textures for more information on Anisotropic filtering.

Texture type: Normal Map

Property:	Function:
Texture Type	Select Normal map to turn the color channels into a format suitable for real-time normal mapping.
Texture Shape	Use this to define the shape of the Texture. See documentation on the Texture Importer for information on all Texture shapes.
Create from Greyscale	This creates the Normal Map from a greyscale heightmap. Check this to enable it and enabled it and see the Bumpiness and Filtering. This option is unchecked 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 Greyscale is checked.
Filtering	Определяет, как рассчитывается рельефность:
Smooth	This generates Normal Maps with standard (forward differences) algorithms.
Sharp	Also known as a Sobel filter, this generates Normal Maps that are sharper than Standard.
Advanced

Packing Tag	Specify by name a Sprite atlas which you want to pack this Texture into.
