遮罩节点¶
遮罩节点可以用来选择一个 遮罩数据块。这个节点可以用于其他节点上，比如反转、正片叠底、混合，或者用作一个输入参数因子。
输入¶
- 羽化
使用或者忽略样条曲线定义的羽化设定。具体参看 遮罩羽化 获取更多细节。
运动模糊¶
For animated masks, creating a motion blurred mask from the surrounding frames.
- 采样
Number of motion blur samples. Higher values result in smoother and more accurate blur, but increase processing time.
- 快门
Duration of the motion blur in seconds, corresponding to the exposure time simulated for each frame.
属性¶
- 遮罩
可选择的遮罩数据块。如果标签为空白的话，需设置遮罩名称。
- Size Source
Where to get the mask size from for aspect/size information.
- 场景尺寸:
Will give an image the size of the render resolution for the scene, scaling along when rendering with different resolutions.
- 固定:
gives a fixed size in pixels.
- Fixed/Scene:
gives a size in pixels that still scales along when changing the render resolution percentage in the scene.
输出¶
- 遮罩
遮罩的黑白值输出。
