Good to know
Spatial selection
Nest choices for horizontal provinces or stacked cave, ground and floating-island layers. Selection assigns air as well as solid positions. It does not union or blend independently generated terrain: share upstream density fields where continuity is wanted.
Current boundaries
Connect exactly one of regions or legacy selector on World Output. Region worlds require zero biome edge and transition radii. Use Region Membership and Distance to Region Edge downstream for masks and transitions; neither may drive the classifier. Legacy biome-edge queries remain unsupported in region worlds. Membership is independent of biome appearance.
