and they are great for skin, landscapes, or just about anything. Figure

Texture
Tools in the Texture category are used for creating and working with
UV maps, which you can think of as the unwrapped skins of 3D models,
flattened out on a grid with coordinate axes U and V. You can
???paint??? colors and textures onto a UV map in a third-party programs
like Adobe Photoshop, then rewrap the model with it. UVs are often
used in video games because one image can be used to surface an
entire object. Have you ever put together a model of a car when you
were a kid? Do you remember that huge sheet of stickers that you
would apply to the model after building it? In a way, a UV map is like
that big sheet of stickers.
