Introduction Introduction
************ ************
The UV Editor is used to map 2D assets like images/textures The UV Editor is used for editing UV maps, which describe how a 2D image should be mapped
onto 3D objects and edit what are called UVs. onto a 3D object.

The most flexible way of mapping a 2D texture over a 3D object is a process called "UV mapping". Image textures are typically needed when the desired look is hard to achieve with procedural textures,
In this process, you take your three-dimensional (X, Y & Z) mesh and unwrap it to a flat two-dimensional or if the texture is not uniform. For example, a car would only have scratches in a few places where they make sense,
(X & Y ... or rather, as we shall soon see, "U & V") image. Colors in the image are thus mapped to your mesh, not in random places all over its body.
and show up as the color of the faces of the mesh. Use UV texturing to provide realism to your objects that
procedural materials and textures cannot do, and better details than Vertex Painting can provide. Blender offers a number of projections (Box, Sphere...) that automatically apply a 2D image to a 3D object,
but these tend to only work for simple meshes. For more complex ones, you need to create a UV map instead.
This is a flat area where each face of the 3D object is laid out on the 2D image, specifying which part of the
image it should be textured with. This gives you complete control over the mapping process.
The name "UV" refers to the axes of the map: U for horizontal, V for vertical. These letters were chosen to
avoid confusion with "X" and "Y", which refer to axes in 3D space instead.
UVs Explained UVs Explained
============= =============
The best analogy to understanding UV mapping is cutting up a cardboard box. The best analogy to understand UV mapping is cutting up a cardboard box.
The box is a three-dimensional (3D) object, just like the mesh cube you add to your scene. If you were to take a pair of scissors and cut along its edges,

If you were to take a pair of scissors and cut a seam or fold of the box,

we could say that U is the left-right direction, and V is the up-down direction. we could say that U is the left-right direction, and V is the up-down direction.
This image is thus in two dimensions (2D). We use U and V to refer to these
"texture-space coordinates" instead of the normal X and Y, which are always used
(along with Z) to refer to the three-dimensional space (3D).
When the box is reassembled, a certain UV location on the paper is transferred to an (X, Y, Z) As a next step, you could put the spread-out box on top of a poster, cut the poster
location on the box. This is what the computer does with a 2D image in wrapping it around a 3D object. to match its shape, glue the poster to the box, and finally reassemble the box.
You now have a 3D box textured with a 2D image.
During the UV unwrapping process, you tell Blender exactly how to map the faces of your object (in this case, a box) A UV map describes how the box is cut up, and how it's laid out on the poster.

and then arrange them in some way upon a photograph that is also lying on that tabletop.)

In this image you can easily see that the shape and In the above image, a dome in 3D space is flattened into a disc in UV space.
size of the marked face in 3D space is different in UV space. Each 3D face is then textured with the part of the image it covers in the UV map.
This difference is caused by the "stretching" (technically called mapping)
of the 3D part (XYZ) onto a 2D plane (i.e. the UV map).
If a 3D object has a UV map, then, in addition to the 3D coordinates X, Y, and Z, The image also demonstrates a common problem in UV maps: distortion. Notice how,
each point on the object will have corresponding U and V coordinates. even though the checkered squares in the 2D texture are all the same size,
they get different sizes when applied to the 3D dome (they're smaller at the base
than at the top). This is because the faces in the UV map have different relative
sizes than in 3D space, which is a result of the flattening process.
.. note:: You'll typically want to minimize this distortion by manually guiding and tweaking
the flattening, using :doc:`seams </modeling/meshes/uv/unwrapping/seams>` for example.
However, it's not always possible to eliminate it completely.
On more complex models (like seen in the sphere above)
there pops up an issue where the faces cannot be cut,
but instead they are stretched in order to make them flat.
This helps making easier UV maps, but sometimes adds distortion to the final mapped texture.
Advantages of UVs
=================
While procedural textures are useful -- they never repeat themselves and always "fit" 3D objects
-- they are not sufficient for more complex or natural objects.
For instance, the skin on a human head will never look quite right when procedurally generated.
Wrinkles on a human head, or scratches on a car do not occur in random places,
but depend on the shape of the model and its usage. Manually-painted images,
or images captured from the real world gives more control and realism.
For details such as book covers, tapestry, rugs, stains, and detailed props,
artists are able to control every pixel on the surface using a UV texture.
A UV map describes what part of the texture should be attached to each polygon in the model.
Each polygon's vertex gets assigned to 2D coordinates that define which part of the image gets mapped.
These 2D coordinates are called UVs (compare this to the XYZ coordinates in 3D).
The operation of generating these UV maps is also called "unwrap",
since it is as if the mesh were unfolded onto a 2D plane.
For most simple 3D models, Blender has an automatic set of unwrapping algorithms that you can easily apply.
For more complex 3D models, regular Cubic, Cylindrical or Spherical mapping, is usually not sufficient.
For even and accurate projection, use :doc:`seams </modeling/meshes/uv/unwrapping/seams>` to guide the UV mapping.
This can be used to apply textures to arbitrary and complex shapes,
like human heads or animals. Often these textures are painted images,
created in applications like the Gimp, Krita, or your favorite painting application.

This operator selects all UVs that are connected to currently selected UVs. Selects all elements that are connected to the currently selected ones.
This works similarly to the tools in 3D Viewport.

Compare Compare

:Equal: Select items with the same value as the active item's chosen property. :Equal: Select elements whose value is equal.
:Greater: Select items with a larger value as the active item's chosen property. :Greater: Select elements whose value is greater or equal.
:Less: Select items with a smaller value as the active item's chosen property. :Less: Select elements whose value is less or equal.
Threshold Threshold
For quantitative properties, this property controls how Tolerance for values that are almost, but not quite the same. A higher threshold will select more elements.

Select Split :kbd:`Y` Select Split :kbd:`Y`
Cuts apart the selected UVs from the map. Only those UVs which belong to "Detaches" the selected faces so they can be moved elsewhere without affecting their neighbors.
fully selected faces remain selected. As the name implies, this is particularly useful to
unlink faces and move them elsewhere. The hotkey is analogous to the mesh Split tool. .. hint::
Unlike :doc:`Split Selection </modeling/meshes/editing/mesh/split>` for meshes, which physically disconnects
faces, this is a pure selection operator. In UV space, the faces were never connected to begin with; it only seemed
that way because *Sticky Selection* automatically selected the vertices of the neighboring faces.
*Select Split* deselects those vertices again.
As an alternative to *Select Split*, you can set the *Sticky Selection Mode* to *Disabled*.
Select Overlap Select Overlap
Selects any UVs that are extended over other UVs while also selecting any underlying UVs. Selects all UV faces that overlap each other.
