Textures are laid on top of materials to give them complicated colors and other effects. An object is covered with a material, which might contain several textures.
Having said everything about Textures in Blender in the previous tutorials, many people find it still hard to grasp the concepts behind the texturing system and applying textures.
Not only can textures affect the color of a material, they can also affect many of the other properties of a material. The different aspects of a material that a texture influences are controlled in the Map To panel.
If you choose the Texture Type Image in the Texture Panel, the Map Image and Image panels appear, allowing you to control most aspects of image textures and how they are applied.
As an alternative to using the Texture Channels, Blender includes a node-based texture generation system which enables you to create textures by combining colors, patterns and other textures in much the same way that you combine Material Nodes.
How to bake a texture to its UV-mapped texture. This can be used to emulate the effects of lightening, texturing and other effects to make your object look as it dose in a render inside blenders game engine. These UV textures can also be exported with the model and be used in 3d games made with other applications as well.
