detail.whyNotDrawn

Answer why a piece of a world's detail is not on screen. The subject is an entity name or id, a voxel chunk ({ entity, chunk }), a mesh-LOD level ({ entity, level }) or a streaming cell ({ cell }). Returns one reason from the closed set — drawn, notManaged, notBuilt, buildQueued, buildFailed, builtEmpty, emittedNothing, outsideRadius, evicted, coarserLevel, finerLevel, noSuchLevel, hidden — with a detail line naming what it is about, carrying the engine's own message when a mesh build was dropped.
