For the rest I have to find a way to integrate rivers but it's not easy lol.
Update 1.1 :
-- Better tiles alignment in Asset Forge --
-- More details on the different tiles --
-- You have 15 tiles already built in the "AF_Mini-world_1.1.rar" --
-- the "AF_All_SaveFiles.rar" file contains 15 save files for use with Asset Forge and you can full custom the all tiles :)
Here are the old tiles in version 1.0
