This macro creates a perlin noise texture based on the world position pass data of an image. This means that the noise will stay attached to your geometry while the camera is moving. Useful to roughen up the edges of a mask created by the Volume Mask tool.

Main Inputs
The following inputs appear on the tool's tile in the Flow Editor:
- Input
- Source image. Required. For this macro to create any output, the input image needs world position pass coordinates in the respective extra channels.
Controls Tab
Slider control. Define the scale of the noise along each axis.
Slider control. Multiplies the noise values by this factor.
Slider control. By default, the noise values will oscillate around zero. This value is added to the noise. A value of 0.5 will create a noise that oscillates around mid-gray.
Slider control. You can move the noise pattern along each axis using these sliders.
Checkbox. If the world position pass contains zero values where the alpha channel is black, they will be replaced by a gray color if the move sliders are changed. If you enable this checkbox the noise will be multiplied by the image's alpha channel, to make these pixels black again.
