As ferramentas para pesos de influência.¶

Blender provides a set of helper tools for Weight Painting.

Opções para subconjuntos

Some of the tools also provide a Subset filter to restrict their functionality to only specific vertex groups (in the Adjust Last Operation panel, displayed after the tool is called) with following options:

Grupo ativo
Ossos de pose selecionados
Deform Pose Bones
Todos os grupos

All tools also work with Vertex Selection Masking and Face Selection Masking. In these modes the tools operate only on selected vertices or faces.

Atribuir a partir dos envelopes de ossos¶

Apply the envelope weight of the selected bone(s) to the selected vertex group.

Atribuir automaticamente a partir do osso¶

Aplica os pesos de influência a partir dos ossos selecionados para o grupo de vértices os mesmos métodos de aplicação de «pesos de influência automáticos» como os que estão disponíveis no menu de «Definir parente para…» quando uma armação está selecionada.

Normalize All¶

For each vertex, this tool makes sure that the sum of the weights across all vertex groups is equal to 1. This tool normalizes all of the vertex groups, except for locked groups, which keep their weight values untouched.

Lock Active: Mantém os valores do grupo ativo enquanto normaliza todos os outros.

Normalizar¶

This tool only works on the active vertex group. All vertices keep their relative weights, but the entire set of weights is scaled up such that the highest weight value is 1.0.

Normalize example.¶

Espelhar¶

The Mirror Vertex Group tool mirrors the weights from one side of a perfectly symmetrical mesh to the opposite side. Only mirroring along local X axis is supported. Those vertices that have no corresponding vertex on the other side will not be affected. But note, the weights are not transferred to the corresponding opposite bone weight group.

Mirror example.¶

Mirror Weights: With this option checked, every selected vertex receives the weight information of its symmetrical counterpart. If both vertices are selected, it will be a weight information exchange; if only one is selected, information from the unselected will overwrite the selected one. Information on weight is passed for the active group only, unless All Groups is checked, in which case it is passed for all groups.
Inverter os nomes de grupos: Works with selected vertices that belong to vertex groups with «symmetrical names» (with components like «L», «R», «right», «left»). All selected vertices that belong to the active group, or to the symmetrical of the active group, will have their assignation to that group replaced by an assignation to the symmetrical one; however, its weight will be preserved. If All Groups is checked, all assignations to these kind of groups will be replaced by the symmetrical counterpart, also keeping the old weights.
Todos os grupos: Operate on all vertex groups, instead of the active one.
Espelhar topologia: Mirror for meshes which are not fully symmetric (approximate mirror). See here for more information.

Dica

Mirror to Opposite Bone

Caso você queira criar um grupo de pesos de influência espelhado para o osso oposto (de um personagem simétrico), então você poderá fazer isto:

Delete the target vertex group (where the mirrored weights will be placed).
Create a copy of the source bone vertex group (the group containing the weights which you want to copy).
Rename the new vertex group to the name of the target vertex group (the group you deleted above).
Select the target vertex group and call the Mirror tool (use only the Mirror weights option and optionally Topology Mirror if your mesh is not symmetric).

Invert¶

Substitua cada um dos pesos de influência dos pesos selecionados pela influẽncia multiplicada por -1.0.

Exemplos:

Original 1.0 converte para 0.0
Original 0.5 permanece 0.5
Original 0.0 converte para 1.0

A inversão.¶

Subset: Restrict the tool to a subset. See above The Subset Option about how subsets are defined.
Add Weights: Adiciona vértices que não têm pesos antes da inversão (todos estes pesos serão definidos para 1.0).
Remove Weights: Remove vértices do grupo de vértices se eles forem 0.0 depois da inversão.

Nota

Locked vertex groups are not affected.

Limpar¶

Clean Vertex Group Weights unassigns vertices from Vertex Groups whose weights are below the Limit. Removes weights below a given threshold. This tool is useful for clearing your weight groups of very low (or zero) weights.

In the example shown, a cutoff value of 0.2 is used (see operator options below) so all blue parts are cleaned out.

Note que as imagens utilizam a opção Ativo(a) para Mostrar pesos zero: (na aba opções) de maneira que os pesos de influência não referenciados são mostrados na cor preta.

Clean example.¶

Subset: Restrict the tool to a subset. See above The Subset Option for how subsets are defined.
Limit: This is the minimum weight value that will be kept in the group. Weights below this value will be removed from the group.
Manter um único: Ensure that the Clean tool will not create completely unreferenced vertices (vertices which are not assigned to any vertex group), so each vertex will keep at least one weight, even if it is below the limit value!

Quantificar¶

This operator uses a process known as Quantization which takes the input weights and clamps each weight to a number of steps between (0 - 1), so there is no longer a smooth gradient between values.

../../_images/sculpt-paint_weight-paint_editing_quantize-example.png

Quantize example (Steps = 2).¶

Passos: The number of steps between 0 and 1 to quantize the weights into. For example 5 would allow the following weights [0.0, 0.2, 0.4, 0.6, 0.8, 1.0].

Levels¶

Adds an offset and a scale to all weights of the selected weight groups. with this tool you can raise or lower the overall «heat» of the weight group.

Nota

Nenhum peso de influência qualquer será definido para valores que estiverem acima de 1.0 ou abaixo de 0.0, independentemente das configurações e / ou definições.

Levels example.¶

Subset: Restrict the tool to a subset. See above The Subset Option for how subsets are defined.
Deslocamento: A value from the range (-1.0 - 1.0) to be added to all weights in the vertex group.
Ganho: Todos os pesos de influẽncia dentro do subconjunto serão multiplicados com o ganho.

Nota

Quaisquer que sejam os valores de Ganho e Deslocamento que você escolher, e para todos os casos, o valor final dos pesos de influência serão limitados (truncados) dentro do intervalo de amplitude de (0.0 a 1.0). Portanto, você jamais terá como resultado pesos de influência negativos (congelamento ou pesos < 0.0 ) ou pesos de influência acima de 1.0 (superaquecimento ou pesos > 1.0) através da utilização desta ferramenta.

Suavizar¶

Dica

The Smooth tool only works when «Vertex selection masking for painting» is enabled. Otherwise the tool button is grayed out.

O método para a mesclagem dos vértices selecionados com os vértices não selecionados adjacentes. Esta ferramenta funciona somente no modo de seleção de vértices.

../../_images/sculpt-paint_weight-paint_editing_smooth-example-1.png

Para entender o que a ferramenta realmente faz, vamos dar uma olhada em um exemplo simples. Os vértices selecionados estão conectados a quatro vértices adjacentes (marcados com um círculo cinza na imagem). Todos os vértices adjacentes estão de-selecionados. Agora, a ferramenta calcula a média dos pesos de influência de todos os vértices conectados e de todos os vértices não selecionados. Neste exemplo, isto é:

\((1 + 0 + 0 + 0) / 4 = 0.25\)

Este valor é multiplicado pelo fator fornecido dentro dos parâmetros do operador (veja abaixo).

Caso o fator seja 0.0, então atualmente nada ocorrerá em todos os vértices. Todos os seus valores serão mantidos.
Caso o fator seja 1.0, então a média dos pesos de influência calculados é tomada (0.25 aqui).
Arrastar o fator entre 0 e 1 gradualmente fará alterações a partir do valor anterior para a média calculada.

../../_images/sculpt-paint_weight-paint_editing_smooth-example-2.png

Agora vamos ver o que ocorre quando nós selecionamos todos menos um dos vizinhos dos vértices selecionados também. Novamente todos os vértices conectados e não selecionados são marcados com um círculo cinza. Quando chamamos a ferramenta Suavizar nesse momento e definimos o fator para 1.0, então vemos que há diferentes resultados para cada um dos vértices selecionados.

The top-most and bottom-most selected vertices:

estão circundados por três vértices não selecionados, com um peso médio de influência de \((1 + 0 + 0) / 3 = 0.333\) . Portando as suas cores foram alteradas para verde claro.
O vértice do meio:

is connected to one unselected vertex with weight = 1. So the average weight is 1.0 in this case, thus the selected vertex color has changed to red.
O vértices á direita:

is surrounded by three unselected vertices with average weight = \((0 + 0 + 0) / 3 = 0.0\) So the average weight is 0, thus the selected vertex color has not changed at all (it was already blue before Smooth was applied).

../../_images/sculpt-paint_weight-paint_editing_smooth-example-3.png

Finalmente, vamos observar um exemplo prático. Neste exemplo, o anel de arestas no meio foi selecionado e será usado para a mesclagem com a lateral esquerda em relação ao lado direito da área.

Todos os vértices selecionados possuem dois vértices adjacentes não selecionados.
A média de pesos de influência dos vértices não selecionados é de \((1 + 0) / 2 = 0.5\).
Portanto, quando o Fator é definido para 1.0, então o anel de arestas se torna verde e finalmente mescla-se com o lado mais frio (direito) do lado mais quente (esquerdo).

Fator

The effective amount of blending. When Factor is set to 0.0 then the Smooth tool does not do anything. For Factor > 0 the weights of the affected vertices gradually shift from their original value towards the average weight of all connected and unselected vertices (see examples above).

Iterations

Number of times to repeat the smoothing operation.

Expandir ou Contrair

Positive values expand the selection to neighboring vertices while contract limits to the selection.

Fonte

The vertices to mix with.

Todos: Smoothing will smooth both selected and deselected vertices.
Only Selected: Smoothing will only smooth with selected vertices.
Only Deselected: Smoothing will only smooth with deselected vertices.

Transferência de pesos de influência¶

Copy weights from other objects to the vertex groups of the active object.

By default this tool copies only the active (selected) vertex group of the source object to the active vertex group of target object or creates a new one if the group does not exist. However, you can change the tool’s behavior in the Adjust Last Operation panel.

For example, to transfer all existing vertex groups from the source objects to the target, change the Source Layers Selection option to By Name.

Nota

This tool uses the generic «data transfer», but transfers from all selected objects to active one. Please refer to the Data Transfer docs for options details and explanations.

Preparando cópias¶

Você deverá selecionar primeiramente todos os objetos de fonte, e finalmente o objeto alvo (o objeto alvo deverá ser o objeto ativo).

It is important that the source objects and the target object are at the same location. If they are placed side-by-side, then the weight transfer will not work. (See the Vertex Mapping option.) You can place the objects on different layers, but you have to ensure that all objects are visible when you call the tool.

Now ensure that the target object is in Weight Paint Mode. Open the Toolbar and call the Transfer Weights tool in the Weight Tools panel.

Adjust Last Operation Panel Confusion¶

You may notice that the Adjust Last Operation panel stays available after the weight transfer is done. The panel only disappears when you call another Operator that has its own Adjust Last Operation panel. This can lead to confusion when you use Transfer weights repeatedly after you changed your vertex groups. If you then use the still-visible Adjust Last Operation panel, then Blender will reset your work to its state right before you initially called the Transfer Weights tool.

So when you want to call the Transfer Weights tool again after you made some changes to your vertex groups, then always use the Transfer Weights button, even if the Adjust Last Operation panel is still available. Unless you really want to reset your changes to the initial call of the tool.

Limitar total¶

Reduz o número de grupos de pesos por vértices ao limite especificado. A ferramenta remove os pesos de influência mais baixos inicialmente e antes que o limite tenha sido atingido.

Dica

A ferramenta somente poderá funcionar de maneira razoável quando um ou mais grupos de pesos estiverem selecionados.

Subset: Restrict the tool to a subset. See above The Subset Option for how subsets are defined.
Limit: O número máximo de pesos de influência permitidos por cada vértice.

Fix Deforms¶

The Fix deforms tool is used to modify an object’s nonzero weights so its deformed vertices are at a new defined distance. This is helpful to fix deformations because when complex models are deformed to their extreme poses, they are often visibly bumpy, jagged, or otherwise incorrectly deformed. Using this tool, you can smooth over the deformation.

To use the tool, select the vertices that you would like to move, either in Edit Mode or by using the vertex selection/mask. The operator can now be used and altered with these options:

Distância: The distance to move to.
Strength: The distance moved can be changed by this factor.
Precisão: Changes the amount weights are altered with each iteration: lower values are slower.

Nota

Note that if it does not change, then there are no nonzero bone weights that are changed to make it closer to the intended distance.

Locks¶
