In section 6.5.1.5 Height Field.
Last sentence of second to last paragraph:
"You may optionally use a boolean value such as smooth on or smooth off."
Either the documentation or the program is wrong. Attempting to use a
boolean keyword after smooth in a height_field produces the following error
message:
smooth on <----ERROR
Parse Error: No matching } in 'height_field', float function 'on' found
instead
