Novel replacement for the LightParams.dbc + Light.dbc pair vanilla WoW used to drive the per-zone diurnal sky cycle. Each entry binds one (mapId, areaId, timeOfDayHour) triplet to its sky-rendering parameters: sky-dome zenith and horizon colors, sun angle and color, fog start/end distances, cloud-layer opacity, and cloud drift speed in tenths-mph. The renderer interpolates between adjacent keyframes when the in-game clock crosses an hour boundary, so a 4-keyframe set (Dawn/Noon/Dusk/Midnight) produces the full diurnal cycle through linear interpolation. Servers can author finer-grained keyframes (e.g. every 3 hours) for smoother transitions. Three preset emitters demonstrating the catalog's range: makeStormwindDay (4 standard temperate keyframes from lavender dawn through bright noon to deep blue-black midnight), makeNorthrendArctic (4 cold steel-blue keyframes with high-density ice fog peaking at the midnight blizzard whiteout — minimum 30yd visibility), makeOutlandHellfire (3 keyframes — no midnight, since Outland's permanent gravitational anomaly from the Twisting Nether keeps the sky lit; iconic crimson + orange palette throughout). Validator's most novel checks: per-(mapId, areaId, timeOfDayHour) triple uniqueness — two keyframes at the same hour for the same area would render in unstable order during diurnal interpolation. Plus fogStartYards >= fogEndYards (inverted falloff) error, sunAngleDeg outside [0,360] warning (renderer wraps modulo but suggests authoring confusion). Format count 118 -> 119. CLI flag count 1255 -> 1260. |
