By the way, the second part of the maps catalogue is ready to go. It covers all the "maps" (780) included in the tab 'Add -> Item'.
The use of "" in "maps" is intended: the concept in them is different than in the first part. You can't manipulate it in any way and so you have to use them as they are. Even the same idea of what constitute a "map" or not is arguable. For the catalogue, I try to apply a wide standard based in the disposable space: if there is enough as to put a bunch of characters and make a scene, I considered it a map. That's the reason why you will find here boats and trains but not cars or helicopters for example.
The "maps" are arranged in categories, the same as in the first part, with the name of the file reflecting exactly the path to find them (unfortunately, there is no Search function here). The assignation of some "maps" to a specific category was even more dificult than in the first part so, maybe many of you don't agree with my choosing, but don't worry, you can rearrange them at your will: at last, they are for your own usage...
And, here we go
EDIT: Sorry, I forgot to mention the great advantage of these "maps": you can have several of them in the same scene or use it simoultaneously with normal maps. Also, it can be easily moved to any part of your scene.
