New open replacement for WoW's Light.dbc / LightParams.dbc /
LightIntBand.dbc / LightFloatBand.dbc stack — a single .wol
file holds a list of time-of-day keyframes for one zone,
each capturing the ambient + directional + fog state at that
moment. The renderer interpolates between adjacent keyframes
by time-of-day.
Binary layout:
magic[4] = "WOLA", version (uint32),
nameLen + name bytes,
keyframeCount + keyframes (each 13 floats + 1 uint32 time)
Per keyframe:
• timeOfDayMin (0..1439 = minutes since midnight)
• ambientColor.rgb, directionalColor.rgb, directionalDir.xyz
• fogColor.rgb, fogStart, fogEnd
CLI:
• --gen-light <wol-base> [zoneName] — emit a starter file
with 4-keyframe day/night cycle (midnight/dawn/noon/dusk)
using reasonable outdoor defaults
• --info-wol <wol-base> [--json] — inspect: zone name +
per-keyframe time-of-day + colors + fog distances
The 7th open-format addition to the Wowee pipeline:
M2 → WOM (model)
WMO → WOB (building)
WMO collision → WOC
ADT → WOT (terrain)
DBC → JsonDBC
BLP → PNG
Light.dbc family → WOL ← new
Smoke-tested round-trip: gen → info shows correct 4 keyframes
at 00:00 / 06:00 / 12:00 / 18:00 with the canonical color
ramps. JSON output for tooling integration.
