Ill have a look on monday =3
im working this weekend and usualy arive around 10pm at home so im kinda fatigued xD i bike to and from work and it takes its time =P
but to be quick on it.
Ninja Adventures has a really good tilemap you can have a look at, This is the Asset pack its called "Tileset Floor". This Video goes thrue how to use it for auto-tiling. probably the best video on auto-tiling ive see
For the water//dirt tile i would recomend something like a sandwall barier making it look like tha dirt is just above the water with some small rocks or something seperating them, could be done the same way you did in your rpg-maker file called "A2_terrains_RPGMaker" on the dirt//grass tiles.
for now, just have a look att the links i sent you and ill have a look att what youve made on monday =D
im looking forward to it ^^'
