Esquema¶

Após o desdobramento, você provavelmente irá precisar organizar os mapas UV em alguma coisa que possa ser texturizada ou pintada de uma forma inteligível. Seus objetivos para a edição são:

Costura algumas peças (mapas UV) formando um único conjunto.
Minimiza o espaço desperdiçado em uma imagem.
Alarga as faces onde você deseja mais detalhes.
Redimensiona / Alarga as faces que estão esticadas.
Encolhe (ou recolhe) as faces que estiverem muito granulares e que possuem muitos detalhes.

With a minimum of dead space, the most pixels can be dedicated to giving the maximum detail and fineness to the UV texture. A UV face can be as small as a pixel (the little dots that make up an image) or as large as an entire image. You probably want to make some major adjustments first, and then tweak the layout.

Bloqueio de eixos¶

As transformações podem ser bloqueadas para um dos eixos pressionando X ou Y após acionar alguma das ferramentas de transformação. Adicionalmente, manter o BMM pressionado também funciona para restringir os movimentos para o eixo X ou Y.

Opções para UVs¶

Desdobramento contínuo: Desdobra continuamente as ilhas de UVs selecionadas durante as transformações de vértices afixados.
Atrair para pixeis: Irá forçar as UVs a ser atraídas para os pixeis mais próximos de uma imagem, caso carregada.
Restringir para os limites da imagem: Habilitar a opção Restringir para os limites da imagem irá evitar que as UVs sejam movidas para fora da amplitude entre 0 e 1.

Afixar e desafixar¶

Panel:	Tool Shelf ‣ Tools ‣ UV Tools ‣ UV Unwrap: Pin/Unpin
Menu:	UVs ‣ Pin/Unpin
Hotkey:	`P`, `Alt-P`

You can pin UVs so they do not move between multiple unwrap operations. When Unwrapping a model it is sometimes useful to «Lock» certain UVs, so that parts of a UV layout stay the same shape, and/or in the same place. Pinning is done by selecting a UV, then selecting Pin from the UVs menu, or the shortcut P. You can Unpin a UV with the shortcut Alt-P.

Pinning is most effective when using the Unwrap method of UV mapping, for organic objects. An example is when you are modeling a symmetrical object using the Mirror Modifier. Some of the UVs on the mirror axis may be shared across the mirrored counterparts. You could pin the UVs that correspond to the midline, then align them on the X axis, and they will stay in that location.

Pinning also work great with the Live Unwrap tool. If you pin two or more UVs, with Live Unwrap on, dragging pinned UVs will interactively unwrap the model. This helps with fitting a UV island to a certain shape or region.

Costuras¶

Empacotar ilhas¶

Mode:	View mode
Panel:	Tool Shelf ‣ Tools ‣ UV Tools ‣ Pack Islands
Menu:	UVs ‣ Pack Islands
Hotkey:	`Ctrl-P`

The Pack Islands tool generates an optimized UV layout with non-overlapping islands that tries to efficiently fill the texture space.

First it will uniformly scale the selected island, then individually transform each island so that they fill up the UV space as much as possible.

Escalonar as ilhas por uma média¶

Referência

Mode:	View mode
Panel:	Tool Shelf ‣ Tools ‣ UV Tools ‣ Average Island Scale
Menu:	UVs ‣ Average Island Scale
Hotkey:	`Ctrl-A`

Using the Average Island Scale tool, will scale each UV island so that they are all approximately the same scale.

Minimizar esticamento¶

Mode:	View mode
Panel:	Tool Shelf ‣ Tools ‣ UV Tools ‣ Minimize Stretch
Menu:	UVs ‣ Minimize Stretch
Hotkey:	`Ctrl-V`

The Minimize Stretch tool, reduces UV stretch by minimizing angles. This essentially relaxes the UVs.

Costurar¶

Panel:	Tool Shelf ‣ Tools ‣ UV Tools ‣ Stitch
Menu:	UVs ‣ Stitch
Hotkey:	`V`

The Stitch tool, will join selected UVs that share vertices. You set the tool to limit stitching by distance in the Operator panel, by activating Use Limit and adjusting the Limit Distance

Copiar as coordenadas UV espelhadas¶

Referência

Mode:	View mode
Panel:	Tool Shelf ‣ Tools ‣ UV Tools ‣ Copy Mirrored UV Coordinates
Menu:	UVs ‣ Copy Mirrored UV Coordinates

Copies UVs from one side of the mirrored mesh to the other. Affects only selected vertices (on both sides).

Axis Direction: Positive/Negative
Precision: Tolerance for finding vertex duplicates.

Espelhar¶

You can also use the hotkey Ctrl-M, then enter X or Y, or hold the MMB and drag in the mirror direction.

Atrair¶

Menu:	Mesh ‣ Face ‣ Rotate UVs/Reverse UVs

The orientation of the UV texture is defined by each face. If the image is, for example, upside down or laying on its side, use the Face ‣ Rotate UVs (in the 3D View in Face Select mode) menu to rotate the UVs per face in 90-degree turns.

The Face ‣ Reverse UVs tool mirrors the UVs per face, which flips the image over, showing you the image reversed.
