1) I wasn't happy with the way rivers transitioned into the coast. Colors adjusted. 2) I wanted a Marsh set for Sn00pys, but didn't like any I found, so I darkened the vegetation a bit and adjusted the water color - closer to the color of the rivers that sometimes move through them. 3)I liked the 'muddy floodplains' idea, but not the extent of the brown on them, so I made my own for this terrain set. Edit: I suggest that anyone using this mod check out Better Desert, Floodplain and Bonus Grassland through the use of tnt.pcx for a powerful complimentary mod.
