Yes, but the key here is that our random vegetation code already uses
a grid, with pseudo random numbers used to determine whether a grid
has an instance, and to deviate the coordinates of the instance from
grid alignment. This can give a nice random distribution, or if the
random factors are reduce, the same algorithm can give a nice grid
like pattern of plants, with a nice natural fuziness.\
