# 编辑

Blender提供了一组权重绘制的工具。

Some of the tools also provide a Subset filter to restrict their functionality to only specific vertex groups (in the 调整上一步操作 panel, displayed after the tool is called) with following options:

• 活动组

• 选择姿势骨骼

• 形变姿态骨骼

• 全部组

## 镜射

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(上文删除的组)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

Tip

Blend工具只在启用“绘制时顶点选择遮罩”才起作用。否则，该工具按钮变灰。

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

• 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：

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

• 右顶点：

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 has not changed at all (it was already blue before Smooth was applied).

• 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)。

## 传递权重

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 调整上一步操作 panel.

Note

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.

### 调整上一步操作面板混淆

You may notice that the 调整上一步操作 panel stays available after the weight transfer is done. The panel only disappears when you call another Operator that has its own 调整上一步操作 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 调整上一步操作 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 调整上一步操作 panel is still available. Unless you really want to reset your changes to the initial call of the tool.

Vertex groups can be locked to prevent undesired edits to a particular vertex group.
