# 权重工具¶

模式: 编辑模式和权重绘制模式 工具栏 ‣ 工具 ‣ 权重工具 权重

Blender provides a set of helper tools for Weight Painting. The tools are accessible from the Tool Shelf in Weight Paint Mode. And they are located in the Weight Tools panel.

## 子集选项¶

• 激活的组
• 选中的姿势骨骼
• 变形姿势骨骼
• 所有的组

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

## 镜像¶

### 选项¶

Tip

1. 删除目标顶点组（将放置镜像权重的位置）。
2. 创建源骨骼“顶点组”（包含要复制的权重的组）的副本。
3. 将新的顶点组重命名为目标顶点组（你在上面删除的组）的名称。
4. 选择目标顶点组并调用镜像工具（如果网格不对称，则仅使用镜像权重选项和可选的 拓扑镜像）。

• 原始的1.0转换为0.0
• 原始0.5仍然是0.5
• 原始0.0转换为1.0

Note

## 数值化¶

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.

### 选项¶

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].

## 光滑¶

Tip

Blend工具只在启用“绘制时顶点选择遮罩”才起作用。否则，工具按钮变灰。

:math: (1 + 0 + 0 + 0) / 4 = 0.25

• 如果系数是0.0，那么实际上什么也没有发生，顶点只是保持它的值。
• 如果系数(因子）是1.0，则计算平均权重（在此为0.25）。
• 将系数（因子）从0拖到1逐渐从旧值改变到计算的平均值。

• 最顶部和最底部的选定顶点：

被三个未被选择的顶点包围，平均权重为 $$(1 + 0 + 0) / 3 = 0.333$$ 因此，它们的颜色变成浅绿色。

• 中间顶点：

与“权重= 1”未选中的顶点连接。所以在这种情况下平均权重是1.0，因此选定的顶点颜色已经变成红色。

• 右顶点：

被平均权重= $$(0 + 0 + 0) / 3 = 0.0$$ 的三个未选择的顶点包围。因此，平均权重为0，因此所选顶点颜色根本没有改变（在平滑之前它已经是蓝色）。

• 所有选定的顶点都有两个未选中的相邻顶点。
• 未选定顶点的平均权重为 $$(1 + 0) / 2 = 0.5$$
• 因此，当 系数 设置为1.0时，边循环变为绿色，最后混合冷端（右）和热端（左）。

### 选项¶

Number of times to repeat the smoothing operation.

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

The vertices to mix with.

All
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.

## 修正形变¶

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:

Distance
The distance to move to.

The distance moved can be changed by this factor.
Accuracy
Changes the amount weights are altered with each iteration: lower values are slower.

Note

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.

## 传递权重¶

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 Operator 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.

Note

### 准备副本¶

Now ensure that the target object is in Weight Paint mode. Open the Tool Shelf and call the Transfer Weights tool in the Weight Tools panel.

### 操作面板混淆¶

You may notice that the Operator panel stays available after the weight transfer is done. The panel only disappears when you call another Operator that has its own Operator 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 Operator panel, then Blender will reset your work to its state right before you initially called the Transfer Weights tool.
