Meshes instead of terrains

Hi all!
For example some time ago we couldn’t use terrains on Android.
I suggest I could use mesh, but how I can paint it with different textures like dirt, rocks, grass etc. Is it done in some 3d modelling software like 3d max?
Can anybody explain process briefly.
Thanks

You can use terrains on Android in Unity 3.4. You can’t paint a mesh with textures etc. the way you do with terrains, at least not without writing your own system that would implement that.
