Metadata

// UCClusterMetadata is created during finalize_sync for each cluster.
// fogOfWar is computed from the cluster bounds with a 5% overflow:
// a = (2*origin.a + origin.b) / 3, b = (2*origin.b + origin.a) / 3
// then expanded by overflow factor.

// metaMargeForBetterWorldEasing doubles the cluster extent:
// a_out = a + (a - b), b_out = b + (b - a)
// This ensures smooth terrain easing around cluster boundaries.

// Per-cluster noise is optional:
if (cMd->roomMakerStruct->clusterSpecificNoise) {
    UCNoisator::instanciate(this, noisator, seed,
        cMd->roomMakerStruct->clusterSpecificNoise->fastNoiseStruct,
        cMd->roomMakerStruct->clusterSpecificNoise->noiseStructArray);
    cMd->specificTopography = noisator;
}

// UCRoomMetadata is created during finalize_sync for each room.
// Doors are computed by intersecting MST corridor edges with the room rectangle.

UCRoomMetadata* meta = roommaker->retrieveRoomMetadata(room);

// Access door positions:
for (const FCRectangleDoor& door : meta->doorArray) {
    FVector2D doorPos = door.intersection;
    // door.rectangleEdge is the room edge intersected
    // door.mstEdgeIndex is the corridor edge index
}

// Check room ordering on longest path:
if (meta->orderOnLongestPath >= 0) {
    // room is on the longest path, ordered by index
}

// Check consumption state:
if (!meta->consumed) {
    // room can still trigger interactions
}
