| Name | Type | Default | Range | What it does |
|---|---|---|---|---|
| sunAz | number | 180 | 0 to 360 deg | compass direction of the Sun that lights the clouds (0 north, 90 east, 180 south) |
| sunAlt | number | 55 | -10 to 90 deg | height of the Sun above the horizon; low suns give long shadows and warm light |
| cover (Can change over time) | number | 0.45 | 0 to 1 | how much of the sky the clouds fill: 0 clear, 0.3 scattered, 0.6 broken, 1 almost overcastCan change over time |
| towering (Can change over time) | number | 0.25 | 0 to 1 | 0 flat fair-weather puffs, 0.5 tall heaps, 1 storm towersCan change over time |
| altitude | number | 2 | 0.4 to 6 km | height of the cloud bases; low bases loom and crowd the sky, high ones look small and far away |
| size | number | 1 | 0.4 to 4 km | typical width of one cloud |
| drift | number | 6 | 0 to 60 m/s | how fast the wind carries the clouds; 6 is a breeze, 25 a gale |
| driftAz | number | 80 | 0 to 360 deg | compass direction the clouds travel toward |
| softness | number | 0.3 | 0 to 1 | 0 crisp, hard-edged cloud, 1 soft and wispy edges |
| detail | number | 0.7 | 0 to 1 | 0 smooth round domes, 1 lumpy cauliflower tops with ragged edges |
| boil | number | 0.25 | 0 to 1 | how fast the cloud shapes churn and change as they drift |
| density | number | 1 | 0.3 to 2.5 | how thick the cloud is; low is thin and bright-edged, high is dense with dark undersides |
| strength (Can change over time) | number | 1 | 0 to 4 | overall brightness; 1 is the physical value for a sunlit cloud (sunlit tops reach 10,000+ cd/m2)Can change over time |
| tint | color | #ffffff | – | colour of the sunlit cloud (before the Sun's own warmth at low altitude) |
| undertone | color | #aebfdc | – | colour of the shaded undersides, lit by the sky |
| shade | number | 0.7 | 0 to 1 | light the shaded sides and undersides add: high is a grey-white body, low leaves only the lit edges |
