Freehand Mask
Updated: 4 Dec 2023
Generates an image mask from hand drawn shapes.
Freehand Mask
Method #
This node generates a black and white mask sketched by clicking and dragging with the left most button in the viewport. When the right button is pressed the mask is cleared.
Notch must be paused to draw new masks.
This node can be connected to any node which accepts an image input.
Parameters
These properties control the core behaviours of the node.
Parameter Details Active Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Preview In Viewport Preview the generated image as an overlay in the viewport.
- Off : No preview is generated.
- RGBA : Preview the image blended with alpha in the viewport.
- RGB : Preview the colour channels in the viewport.
- Alpha : Preview the alpha channel in the viewport.
- PIP : Preview the image blended with alpha in the viewport, in a smaller picture in picture display, on top of the existing content.
Width The resolution of the generated image horizontally.
Height The resolution of the generated image vertically.
Update Time Mode How the generator updates with relation to the timecode.
- Locked To Timecode : The generator animations are locked to the timecode and the same time will always yield the same result.
- Running / Loopable : The generator animations are disconnected from the timecode and will run seamlessly at the end of the composition.
Feather Makes a blur which follows around the edges of the curve mask shape.
Editor Colour Change the colour of the curve mask line, visualised in the viewport.
These properties control how the generators are coloured and blended with other images.
Parameter Details Colour Change the colour of the generated image.
Blend Amount The amount the generated image blends with the project, depending on the compositing mode chosen.
Blend Mode Choose how the image blends with the scene. See Blend Modes for details.
- Solid : The generator is solid, with a filled alpha channel. Blend amount is ignored.
- Blend : The generator RGBA values have matching alpha channels.
- Pre-Mul Blend : The RGB values are solid white, and the generator colours are stored in the alpha channel alpha. Usually gives the best results for colour blending.
These properties contain an array of all the points included to create the mask.
