Variable: DEFAULT_TILE_SIZE

const DEFAULT_TILE_SIZE: 0.05 = 0.05;

Target physical size (world units) for a single hexasphere tile. All bodies derive their subdivision count from this value via tileSizeToSubdivisions(radius, DEFAULT_TILE_SIZE), ensuring every tile across stars, planets and moons has the same surface footprint.

0.05 is the recommended default for a single body in close-up view (~5 000 tiles on a unit-radius body). For multi-body system views, pass a larger value (e.g. 0.10 for 1 250 tiles) to keep the hex count low on background bodies — see the performance guide.
