 Textures work in conjunction with [[Shaders]] and [[Material|Materials]] to produce the final rendering. The game model needs [[Texture Coordinates]] to wrap the texture onto the model. Multiple [[Texture Types]] are often used to control different parts of the shader, such as [[Normal map]] or [[Specular color map]].

 Other surfaces need more specialized shaders and textures, such as Skin or water.
-=== Texture Size ===
 The dimensions of the image, how the model is [[Texture Coordinates|unwrapped]], the scale of the model and scene scale all equate to the resolution of the textured model when seen in-game. It is important that all objects in the scene have similar texture scaling to keep the overall look consistent; a low-resolution image looks jarring when placed next to a high-resolution one. Texture size is the first place to start for this decision, determining [[Texel|texel]], the ratio between UV space/Texture resolution/Scene and object scale when uv unwrapping the model is the second.

-=== Texture Channels ===
 Channels are the color components in the image. Red, Green and Blue (RGB) are each stored as data in separate indices and some software can display each as a greyscale image. An additional channel named Alpha can also be present, but not always rendered into the composite.

-=== Bit Depth ===
+== Bit Depth ==
 [[BitDepth|Bit depth]] is how much data is allotted to each pixel either in memory or in the file. More bits per pixel (bpp) increases the number of colors available for each channel. The 1 bit type has two colors, black and white (or off and on), and is often used for [[Transparency_map|transparent]] alpha testing - a simple sorting for whether or not a pixel is visible. 8 bits gives 256 colors per channel (16.7 million RGB colors), and is often the default mode for most applications. However, higher bpp means increased file size and memory use. It's not uncommon for a format to store colors unequally: 5 bits red, 6 bits green, 5 bits blue, for an example of a total 16 bit storage. Compression is another method to decrease the file size.

 === Texture Types ===
-Depending on the engine and visual style, different types of maps are used for different effects. [[Vertex color]] is optionally used to control additional effects, such as blending between two images in the same model. Images are made up of [[Pixel]]s and are split up into Red, Green and Blue components, also known as channels, and may additionally have an Alpha channel which can be used to store [[Transparency_map|opacity]] or another type of map or mask. Masks are images or layers used to control "How much of What", such as [[Specular_color_map]]s or [[Specular_gloss_map]]s, and are typically (but not always) greyscale (pixels only utilizing one channel).

 For the average prop, arrangements of map types might use Diffuse/Specular/Normal for a current-gen game. [[PBR|Physical Based Rendering]] setup might be Albedo/Microsurface/Reflectivity/Normal for a next-gen shader.
