# WorldChunkLoader
# Dynamically load and unload chunks on a 3D grid.
#
# Direct children should be scenes with Load As Placeholder checked.
# Direct children should be aligned on a grid.
# (To align in 3d scene editor: Transform -> Configure Snap -> Translate Snap.)
# Player should have a WorldChunkGPS component, which sends a signal to here.
#
# Algorithm: load current chunk and all neighbors around it; unload the rest.
