Nodevember 2019 #02 – Clouds

https://nodevember.io/

Made a simple procedural cloud today.  It has a few components. Works well for cumulus clouds, but it’d be fun to make other cloud types as well.

  • 3 components to generate a greyscale mask
    • Z Mask – more density at bottom of clouds (using a color ramp)
    • XY Mask – falloff near edges
    • Cloud Noise – 1 low frequency + 1 high frequency with some distortion for wisps
  • Threshold – Contrast around a chosen midpoint
