    Hi
    How much memory does this terrain setting use. At the moment i have it set to 2048 does that mean its equal to the equivalent of a 2048 texture or is it a lot more expensive than that?

    It's more expensive than that, but depends on what you're doing. Terrains usually have at least 2 textures, one for height and one for texture blending (plus the 1 or more textures you're blending with optional normal maps). I think the terrain also generates a mesh for collision.

    That's all I'm aware of, there may even be more. That said, I don't think you should have to worry about how expensive terrains are unless you're target platform has very little RAM.
