  • 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
