-#    Size of chunks to be generated at once by mapgen, stated in mapblocks (16 nodes).
-#    Increasing this by 1 almost doubles the 3D noise calculation load.
-#    High values can cause noise calculation to overload.
-#    Values smaller than 5 cause a terrain bug in Mapgen V6.
-#    Since there is a fixed number of large caves and dungeons per
-#    mapchunk, values other than 5 alter the density of these.
+#    Size of mapchunks generated by mapgen, stated in mapblocks (16 nodes).
+#    WARNING!: There is no benefit, and there are several dangers, in

+#    Reducing this value increases cave and dungeon density.
+#    Altering this value is for special usage, leaving it unchanged is
+#    recommended.
