Hello!
I made an add-on to reproduce the Paddy field.
There are two kinds of waterway type and building type.

Already very nice. A factory addon with fields looking like that would be nice too ;)
Nice ! I love it ! ;)
EDIT: but in cause of you did'nt set the maximum speed to 0, the boats can circulate on it ! And every tile is so expansive !

Thank you everyone. :D
The reason for setting the maximum speed high is to move the farm tractor.
In Japan, agriculture is not profitable so we set the maintenance fee high, but it may have been too high.
