 # If this is set to true BlueMap will render Chunks even if there is no light-data!
 # This can be useful for example if some mod prevents light-data from being saved correctly.
 # However, this also has a few drawbacks:
-# - For those chunks, every block will always be fully lit
+# - Cave rendering will always be enabled (BlueMap is using the sky-light data to detect "caves")
+# - Everything will be rendered fully lit (sky-light value of 15, looks similar to having night vision)
 # - Night-mode might not work correctly
-# - Caves will always be rendered (ignoring the 'renderCaves' setting)
 # Default is false
