I\'m assuming you\'re refering to Animatek\'s World Builder? It looks like it will get the job done, but definitely not worth it. You can make 3d landscapes in blender just fine (I think it may even support height maps - look around for a tutorial). I\'m pretty sure only blender and 3ds max have CS exporters, so you would need to be using blender anyway (assuming it has a common format with which to export to). Not to mention, when it comes to populating the maps with buildings and features, blender will again need to be used. My recommendation: don\'t waste your time, learn blender instead. I just pulled blender out again this week to muck around with, and I must say I was pleasantly surprised with the interface and tools (though it will definitely take some getting used to).
