遮罩层¶

Mask Layer panel.
- 遮罩层
- 遮罩层由一个或多个样条线组成,用于对样条线进行“分组”操作。图层可用于创建复杂的形状并定义样条线如何相互交互。可以将属于同一图层的样条一起动画,例如通过动作跟踪器素材中的项目。这种工具的例子可能是将整套样条曲线设置为单个运动跟踪数据,或者简单地将它们全部变换到一起。
- 透明度
- Used to set the opacity of the mask layer.
- Invert (black/white icon)
- Inverts the values (colors) in the mask layer.
- 混合
The layer blending operation to perform. See Color Blend Modes.
Modes Merge Add and Merge Subtract gives better results when using a Feather on overlapping masks than straightforward mathematical addition and subtraction.
- 衰减
- Type of the Feather falloff, controls the shape of the transition between black and white.
- 重叠
- 填充自相交区域。
- 孔洞
- Overlapping splines from the same layer will generating holes in the mask.
示例¶
举例说明遮罩层的用途。假设在镜头中有两个不需要的人,其中一个从左到右,另一个在相反的方向。然后可以使用两个遮罩层分别使用单个遮罩数据块来遮罩它们。在这些形状的交叉点处,它们将被添加在一起而不是创建一个孔洞,如果它们在同一层上发生。如果运动足够简单,则可以使用单个运动跟踪点来驱动整个遮罩层的位置。
遮罩显示¶
- 平滑
- 显示消除锯齿的边缘。
- 边缘绘制类型
- 边缘的风格。
- 叠加
为图像和剪辑编辑器添加遮罩叠加。
- 模式
- Alpha通道
- 它显示为灰度图像的光栅化的遮罩。
- 合成结果
- 带遮罩的多个图像/剪辑。
激活的样条¶

激活的样条面板。
- 羽化偏移
The method used for calculating the offset of the mask spline feather.
- Even
- Preserves the thickness of the feather, but can give undesirable loops of the feather curve.
- 平滑
- Gives a nicer and smoother shape, but can also give an undesirable sharp feather when a curve segment forms an S-shape.
- 权重插值
- The type of weight (thickness of feather) interpolation between points. Linear or Ease (i.e. changes occur slowly at the beginning and at the end).
- 循环
- 如果样条线是闭合的。
- 填充
- Creates splines with filled areas. If disabled, Blender will create curves with a thickness to mask out thin objects such as wires or hair.
- 自相交检查
- Prevent the feather (not the curve itself) from intersecting with itself.
遮罩设置¶
- Start Frame, End Frame
- Set the frame range of the mask for Sequencer.
