What engine are you using? I know it's iphone bust must engines come with a terrain maker were you can just paint the vertices the green or brown texture. A lot of it depends on the engine.
or use vertex color channel blending to blend 2 different tiling textures, its called vertex blending here is a tutorial on how to apply it in max: http://www.bakdesign.net/tm/tutorial/3dsmax_tutorial.html most engines these days support it
That's mip bleeding. The UVs are too close to the edges of your texture, so on the green end it is sampling a bit of the tan side, and vice versa. You need to shrink the UVs on the axis that isn't tiling. Also you'll need to make green edge tile with the green-only texture, but make it tile a few pixels in, where your UV…
so you need to make a test level for an iPhone game, but you don't know how to 3d model? What software are you using? Which iPhone engine? Does it support decal maps in a second UV channel? edit: I'm not trying to be rude here but I don't understand - you don't know how to apply multiple textures to an object, or tile a…
To do the different areas depends on what the engine you are using supports. Can it do blended textures? If so, how do you control it? What app are you using? If it can't do blended textures, then you are going to have to fake it by cutting up the mesh by the different areas. The road can be a mesh on top of the terrain,…
You're missing the beaches? Shouldn't those be raised up also? Your island isn't a dog bone, but a mangled box. Considering there might be more on this island than just grass you might want to start thinking about optimization. Since you're basing your blending on verts, how you optimize it, drastically effects how your…
