Novel open terrain format unique to wowee: .wot (Wowee Open Terrain) — JSON metadata: - Tile coordinates, chunk grid dimensions, texture list - Per-chunk layer assignments and hole bitmasks - Water data per chunk (type, height) - Format version "wot-1.0" .whm (Wowee HeightMap) — binary heightmap: - "WHM1" magic header - 256 chunks × (baseHeight + 145 float heights) = 148KB - Direct float storage, no compression, fully portable Both formats are entirely novel — no ADT, no WDT, no Blizzard structures. The WCP content pack can bundle .wot/.whm instead of ADT/WDT for fully open redistribution. Import/export functions: WoweeTerrain::exportOpen() / importOpen()
